Operator Safety Procedures ALL Operators of US Jetting, LLC Equipment and ALL Operators of US Jetting, LLC Equipment and Accessories MUST READ And UNDERSTAND All Accessories MUST READ And UNDERSTAND All Information Contained Within This Manual Before Information Contained Within This Manual Before Operating A US Jetting High Pressure Jetting Unit.Operating A US Jetting High Pressure Jetting Unit.

NEVER TAKE SAFETY FOR GRANTED! This photo illustrates the destructive power of water at 4,000 PSI when applied to a two-by-four piece of wood. Human limbs can be severed or flesh removed from bone by water pressure alone. Stones, dirt, splinters, pebbles or other de-bris can become airborne that can injure not only operators but fellow co-workers and nearby bystanders. High Pressure Jetting Units are not toys, water streams should never be pointed at persons or animals. All High Pressure Jet-ting Units are powerful machines that require Operators respect always!

Safety Is No

Accident

Personal Protective Equipment (PPE)

Operators and other personal working with or near a High Pressure Jetting Unit always wear proper personal protective equipment (PPE). Operators should always wear the required minimum PPE as recommended by OSHA, company safety officer or company manage-ment. When performing work for customers, operators must check for special safety precau-tions and equipment required at each work site.


EYE PROTECTION All operators or persons in the vi-cinity of the jetting unit and/or the work site, Must Wear Suitable Eye Protection. Eye protection MUST BE WORN to protect against injury from flying debris. High-pressure water will scatter debris into the air. The adjacent picture suggests an acceptable range of eye protection products.

Operator Safety Procedures (continued)

HEAD PROTECTION Operators and nearby workers must wear safety hats or helmets that should ideally include a full face shield.

EAR PROTECTION The noises associated with the high-pressure jetting water stream and engine sources can damage hearing over periods of long exposure. Persons within the im-mediate areas of jetting operations should wear ap-proved personal sound abatement protection.

HAND PROTECTION

An operators hands must come in contact with the high pressure jetting hoses, accessories and noz-zles all of which will be contaminated in some man-ner. Operator should wear two pairs of gloves, an inner pair of latex or rubber gloves to prevent mois-ture contact. A second, outer pair should be of leather or other type of puncture resistant material, heavy duty gloves are essential. The outer gloves should extend up the forearms for protection against water burns or cuts as well as other injuries normally associated with the operation of heavy duty machinery.



FOOT PROTECTION

The feet are most likely to come in contact with a jetting stream. This is especially true for jetting gun operators. Therefore, all operators must wear waterproof boots with steel toe caps and metatarsal (foot bridge) guards.

BODY PROTECTION

All operators must wear suitable waterproof clothing in accordance with the work be-ing done. Garments should provide full cover including arms, legs and torso. Liquid or chemical resistant suits must be worn where there is a possibility of injury from such liquids.

CHEMICAL IRRITANT PROTECTION

When using chemicals or high pressure jetting near or in chemically contaminated pipes or vessels, special safety precautions are always required to prevent chemical related injuries. Operators are responsible for determining proper safety procedures to be implemented and followed at every jobsite. No safety manual can predict or de-termine safety procedures for every job. Onsite Safety Officers, MSDS Sheets and other HAZMAT reference material should be reviewed to determine appropriate PPE safety equipment. In some cases, PPE breathing respirators may be required.

Never Enter a Manhole, Lift Station, Septic Tank,

Catch Basin Without Proper Confined Space

Training and Safety BARRICADE WORK AREA

Operators are responsible for the safe operation of high pressure jetting units as well as maintaining a high level of safety in and around the work area. The work area should be adequately barricaded as to prevent unnecessary workers or unwanted onlookers from gaining access to the work area. The barricaded area should be large enough that any possible flying debris cannot injure nearby people and property. Op-erators and workers must maintain the integrity of the barricaded area during all high pressure jetting operations. If there is a breach in the integrity of the barricaded area, all work must stop while the integrity of the barricaded area is restored.



ALCOHOL, DRUGS & PRESCRIPTION MEDICINES

No Operator or nearby worker shall be allowed to operate or work near a high pres-sure jetting unit if either consumed alcohol within the previous 12 hours prior to the start of work. No Operator or nearby worker shall be allowed to operate or work near a high pressure jetting unit if either display any signs of intoxication. No Operator or nearby worker shall be allowed to operate or work near a high pressure jetting unit if taking legally prescribed medicines without specific written permission from their at-tending physician. No Operator or nearby worker shall be allowed to operate or work near a high pressure jetting unit if either display any signs of illegal drug use. Persons displaying any signs of drug abuse should be removed from the work area and re-ported to authorities.

Inline Water Filter Every US Jetting unit has an inline water filter with a reusable 80 mesh stainless steel filter element. Proper and routine maintenance is required to maintain optimum pump performance and reduce pump maintenance. All debris collected by the filter is contained on the inside of the filter element, not visible through the clear filter cup hosing. Secure the filter cap to the housing, make sure the o-ring is in place. Open the water shut-off and allow water to fill the filter also open the bleed valve on the pump to allow air to escape. No water should leak from the filter cup, water that leaks out also allows air to enter the water system when in operation causing poor pump performance.

To Clean and Replace The Water Filter Engine MUST Be Off

1. Close water shutoff ball valve located between wa-ter filter and water storage tank.

2. Open water shutoff ball valve between water filter and pump to allow most of water to drain from sys-tem and release any vacuum.

3. Loosen to remove the clear water filter cup by turn-ing counterclockwise. If a wrench is required for filter removal, use a nylon strap oil filter wrench only.

4. Remove water filter cup and retain large rubber o-ring for reuse.

5. Remove 80 mesh stainless steel filter element. Us-ing freshwater, wash the dirt and debris from the internal core of the element. Hold the element up to a light source to determine cleanliness.

6. Visually inspect the integrity of the filter element for damage such as holes or deformations. Do not reuse a filter element with any type of physical damage, discard and replace with a new filter ele-ment.

7. Replace filter element in filter cup, place o-ring in filter cup seat and screw entire unit into filter base. Hand tight filter only, do not over-tighten

8. Close main water drain shutoff ball valve. 9. Open water shutoff ball valve from water tank. 10. Open pump bleed valve to purge air from system 11. Check water filter o-ring for water leaks, correct if any. 12. When unit is running at full pressure, check water filter assembly for presence of air bubbles, correct to eliminate ALL air bubbles.

Never Run Unit Without A Water Filter


High Pressure Rupture Disc

Every US Jetting unit has an inline high pressure rup-ture disc to prevent pump and system damage in case of over-pressurization. Operators must always main-tain an awareness of pressure gauge readings. If the maximum working pressure of the high pressure jet-ting unit (4,000 PSI) exceeded, the pumps safety pressure disc will rupture. In the event that the actual system pressure exceeds the recommended system pressure, the rupture disc will blow or rupture dis-charging the excess pressure and water from the sys-tem. High pressure rupture discs once ruptured are not reusable or repairable.

When a high pressure rupture disc ruptures, the sound created is similar to a loud bang or gunshot. Water will then flow through the opening in the disc since the restric-tion on the system has been lessened. When this occurs, the unit should be shut completely down and the disc re-placed.

Pressure rupture discs are located on or near the dis-charge of the high pressure pump. The rupture disc as-sembly is mounted with the disc facing downward, direct-ing expelled water safely to the ground. On units with dual hydrau-lic reels with two sets of pressure and water flow outputs, a second pressure relief disc assembly can be found attached to the lower pressure output hose reel.

If a disc does rupture, operators must determine the cause to prevent a reoccurrence. The first and most common place to check is the nozzle to see if the NOZZLE IS BLOCKED and clear before continuing operations. Second, check for any kinks in the high pressure jetting hose. Occasionally, a disc will burst under normal working pressure because the disc is old and getting worn out.

Note: When using Mini-Jet or Micro Mini-Jet kits, water flow output at the nozzle is reduced and has the potential for a system over-pressurization event. Operators must increase throttle while observing the pressure gauge to set the required working pressure and prevent over-pressurization thus preventing a disc rupture.

High Pressure Rupture Disc

To replace a ruptured disc, unscrew disc holder and replace with appropriate colored disc, see above chart. Use Teflon tape or anti seize compound on threads, install disc holder with new disc and tighten with a wrench. Insert rupture disc (see picture) with the flat smooth surface facing outward and grooved side facing inward. Some ruptured discs may be difficult to remove, requiring a hammer and small chisel for extracting a blown disc.

Rupture discs are to be considered a wear item and spare discs should be kept within the unit for use when necessary. Some rupture discs should be kept in reserve at the office or shop for unit replenishment.

Note: When using Mini-Jet or Micro Mini-Jet kits, water flow output at the nozzle is reduced and has the potential for a system over-pressurization event. Operators must increase throttle while observing either the analog or digital pressure gauges to set the required working pressure for the selected hose to prevent over-pressurization thus preventing disc rup-ture. This is a very common scenario for disc ruptures.

Do Not Exceed Maximum Pressure

Your pump is fitted with a safety rupture disc which will burst if the pump is run at more than the maximum designed pressure.

Never Use Substitute Rupture Discs or Coins Instead of US Jetting Rupture Discs. Serious structural pump

damage and bodily injury can occur.


Standard Water Selector Valve The Water Selector Valve is used to manually turn the high pressure water flow On & Off. Water Selector Valves can be found on all US Jetting High Pressure Sewer Jet-ting units located on the right side of the control panel. The Water Selector Valve is easily identified by its square shape block design fabricated from stainless steel.

Note: For units with the Gen II Wireless Remote Control System, the Water Selector Valve is electrically controlled by an actuator arm. See Gen II Wireless Remote Control System details and operational instructionsSee Page 128 .

The Water Selector Valve is in the OFF position when the valve lever is in the down position. When in the OFF position with the engine & pump operating, water is re-circulated from the pump back to the water storage tank.

The Water Selector Valve should always be in the OFF position be-fore the jetting unit is started.


Standard Water Selector Valve To turn the high pressure water ON, the operating sequence should be: 1. Lift or raise the Water Selector Valve lever to the ON position 2. Increase engine speed to set the desired working pressure. See Engine Throttle

Control . To turn the high pressure water OFF, the operating sequence should be: 1. Decrease engine speed to the idle position. See Engine Throttle Control section. 2. Lower the Water Selector Valve lever to the OFF position

For units with optional Gen II Wireless Remote Control Systems, see Water Selector ON / OFF (Red) Switch operating procedures in the Gen II Wireless Remote Control System section.


Standard Hydraulic Hose Reel All standard US Jetting units are equipped with a hydraulic powered hose reel. The hose reel is controlled by a single lever located to the right of the reel for operator ac-cess. If the US Jetting unit has dual hose reels, the second hose reel will have second control lever located to the right of the reel. Hydraulic hose reels allow for the operator to dispense and retrieve the high pressure jetting hose. It can be operated while jetting with the high pressure hose under pres-sure or with the high pressure water shut-off. The hydraulic hose reel is designed to be strong enough to retrieve the high pressure hose under pressure thus relieving the op-erators physical efforts.

Note: Never use a trailer jetting unit that is not se-curely attached to a tow vehicle. Hydraulic hose reels are powerful enough to move a free-

standing jetting unit. If the nozzle be-comes stuck there is a possibility the hydraulic hose reel can move a free-standing trailer unit causing injury to the operator.

To operate the hydraulic hose reel (with engine running) To dispense High Pressure Jetting Hose: 1. Disconnect the high pressure jetting hose from either the Return to Tank Line or the

Anti-Freeze Return Line 2. Start engine, set engine speed to idle 3. Gently press down on the Hydraulic Reel Control Lever with the Black Red knob

until the reel begins to rotate and dispense high pressure hose. The more the lever

Hydraulic Hose Reel Control Valve Lever

Hydraulic Hose Reel Speed Control Valve


Standard Hydraulic Hose Reel is pressed, the faster the reel will rotate.

4. Release lever to stop rotation. When released, lever will automatically return to the neutral - OFF position

To retrieve or rewind the High Pressure Jetting Hose: 1. Gently raise or lift up on the Hydraulic Reel Control Lever with the Black Red knob

until the reel begins to rotate and rewind high pressure hose. The more the lever is pressed, the faster the reel will rotate.

2. Release lever to stop rotation. When released, lever will automatically return to the neutral - OFF position

NOTE: Operators need to be attentive when paying out high pressure hose while sewer jetting. In some instances, operators can inadvertently dispense high pressure jetting hose faster than the high pressure jetting hose travels with a pipe. This can cause a dangerous hose entanglement and possible injury to the operator.


Standard Hydraulic Hose Reel Hose Reel Swivel Feature: US Jetting Hydraulic Hose reels are mounted on a 7 position swivel pedestal. This feature allows the operator to select an appropriate angle for the hose reel for a spe-cific job application. The hose reel assembly can be swiveled by pressing down on the reel Swivel Lock Lever to release the lock while simultaneously rotating the hose reel in the desired direction. After positioning the hose reel at the desired angle, release the Swivel Lock Lever and move the hose reel slightly in either direction to engage the hose reel lock.

Hydraulic Hose Reel Swivel Lock Release Lever


Optional Hydraulic Power Pull-Out Hose Reel

The optional Hydraulic Power Pull-Out Hose Reel allows for the hose reel to extend and retract from the units frame. Hydraulic Power Pull-Out Reels are included as stan-dard equipment for units mounted within enclosed trucks or enclosed trailers. US Jet-ting units with dual hose reels can be ordered with one or both hose reels supplied with the Hydraulic Power Pull-Out Hose Reel option. Units with Hydraulic Power Pull-Out Hose Reels can be identified by the addition of a second lever next to the Hydraulic Reel Control Lever. The Hydraulic Power Pull-Out level will be indicated by a Red knob. All Hydraulic Power Pull-Out Reel assemblies include a manual 7 position reel swivel that can be positioned by the operator as required. The reel swivel release lever is al-ways located on the lower left side of the hose reel.

Engine Throttle Control A standard style throttle cable used on US Jetting Units that differs only in the length between throttle cable mounting position and the engine. Note that some US Jetting throttle cables have either a red or black colored center but operate in the same man-ner. There is a throttle operational difference between units equipped with an optional Gen II Wireless Remote Control System and standard units. If the high pressure jetting unit is equipped with an optional Gen II Wireless Remote Control System, Refer to GEN II Wireless Remote Control section for throttle operation procedures.

For units with optional Gen II Wireless Remote Control Systems, see throttle setting procedures in the Gen II Wireless Remote Control System section (Page 128).

On standard units (without a GEN II Wireless Remote Control System), the throttle ca-ble can be operated in two methods.


Engine Throttle Control NOTE: When adjusting engine throttle (with the high pressure water selector valve in the ON position) opera-tors need to refer to either the digital or analog pressure gauge to prevent over-pressurization and a possible rup-ture of the high pressure disk.

First, use the twist grip by turning counterclockwise slowly increases the engine speed from idle to full throttle. Turning the grip clockwise will slow the engine speed or return the engine speed to idle. Releasing the grip at any point will maintain the current throt-tle speed setting. This is the suggested method for setting the desired high pressure water output. The second method allows for faster throttle adjustments. Depressing the center red portion of the throttle control cable releases the throttle cable lock for pulling out or pushing in of the throttle cable to set engine speed. This feature is useful for faster en-gine speed slowdowns.

Operators can use either method or in combination to set the desired engine throttle speed at their discretion.

For units with optional Gen II Wireless Remote Con-trol Systems, see throttle setting procedures in the Gen II Wireless Remote Control System section.


Hydraulic Reel Speed Control Valve Most US Jetting units are equipped with a hydraulic reel speed control valve. The valve can be adjusted to set the maximum reel speed (slow to fast) when the Hydraulic Reel Control Valve is in the full payout or retrieve position. Speed adjustment is made to suit the needs and requirements of the operator. The Hydraulic Speed Control Valve works in conjunction with the Hydraulic Reel In-Out Control Valve and to a lesser de-gree with the Hydraulic Power Pull-Out Control Valve. The Hydraulic Reel Speed Con-trol Valve controls the amount of hydraulic fluid passing through the Hydraulic Reel In - Out Control Valve.

Hydraulic Reel Speed Control Valve By adjusting the Hydraulic Reel Speed Control Valve, the operator can set the reel speed to a desired rate even when the engine is operating at maximum throttle. By ad-justing the Hydraulic Reel Speed Control Valve will reduce need for the operator to feather the Hydraulic Reel Control Valve to the desired jetting speed. To control and set the speed rate of the hydraulic hose reel, the high pressure hose should be operational within a manhole to manhole pipeline. 1. Loosen the lock screw on the Flow Adjuster Lever. 2. Move the Flow Adjuster Lever counterclockwise (up) to the minimal flow position. 3. Begin high pressure jetting in a mainline pipe. Operate high pressure jetting unit at

maximum pressure & maximum engine RPM 4. Using the hydraulic reel control, press the lever to maximum flow and hold in posi-

tion. High pressure hose will begin to travel up the pipeline. 5. Move Flow Adjuster Lever clockwise to desired reel speed. 6. Tighten the lock screw on the Flow Adjuster Lever to maintain desired position. Once the hydraulic reel speed is set, it will be the same speed in both the payout and the retrieval of high pressure jetting hose.

NOTE: Operators need to be attentive when paying out high pressure hose while sewer jetting. In some instances, operators can inadvertently dispense high pressure jetting hose faster than the high pressure jetting hose travels with a pipe. This can cause a dan-gerous hose entanglement and possible injury to the operator.


Jump Jet Pulsation System NOTE: These operating procedures are used for standard US Jetting unit and units equipped with GEN II Wireless Remote Control Systems

All US Jetting High Pressure Jetting units designed for sewer and drain cleaning come standard with a Jump Jet Pulsation System. The Jump Jet System, when in the ON position is designed to divert one third of the pressurized water from the high pressure jetting system back to the water tank. When the Jump Jet System is turned ON, this results in a sharp pulse or vibration on the jetting hose. The hose will appear to flutter or vibrate that results in increased ease of movement.

The Jump Jet Pulsation System control valve should only be activated (turned ON or OFF) when the jetting unit is at an idle speed with the water selector valve in the OFF or Return To Dump position. To utilize the Jump Jet Pulsation System, turn the Jump Jet System Valve to the ON position, turn the Water Selector Valve to the ON position and increase engine throttle until the pressure gauges indicates 1,5000 PSI. DO NOT EXCEED 1,500 PSI. Both analog (dial) gauge needle and the LED digital readout will fluctuate or bounce at 1500 PSI, a normal indication of the pressure changes or pul-sations.

Never Operate

Jump Jet Pulsation System Above 1,500 PSI

All Jump Jet Pulsation System control valves (ON / OFFf) installed by US Jetting are identical. The location of the Jump Jet Pulsation System con-trol valves vary on different US Jet-ting models (trailer, truck or skid units), but are normally placed within reach of the main unit control panel and easily identified. Locate and identify the Jump Jet Pulsation Sys-tem control valve before operating the unit.


Jump Jet Pulsation System The Jump Jet Pulsation System allows for increased hose distance while jetting. It can also be used for assisting the nozzle and hose in negotiating 30, 45 & 90 degree pipe bends. When the hose is fully extended, the Jump Jet System is turned OFF. Operate the high pressure jetting unit at full pressure (cleaning the pipe) while retrieving or rewinding the high pressure hose for maximum cleaning effectiveness. Use of the Jump Jet System was designed for increased hose mobility only while sacrificing overall cleaning pipe cleaning effectiveness is reduced (lower pressure and reduced water flow). Use With Small Diameter Hose Cleaning Kits The Jump Jet System can be used with smaller diameter hose kits with the same in-creased hose mobility benefit. The same operating procedures should be followed with operating pressure not to exceed 1500 PSI. Use With Gen II Wireless Remote Control Systems (Option) The Jump Jet System can be used in conjunction with the Gen II Wireless Remote Control System. The Jump Jet System can not be turned ON or OFF remotely, only at the Jump Jet Valve mounted on the unit. Location of Jump Jet Valve If the unit has a Jump Jet System, the control valve will be located on or near the op-erator control panel. On trailer units, the Jump Jet Control Valve is normally located next to the right turn signal lamp but on certain models can be found on the control panel attached to the hose reel. On truck mounted units, the Jump Jet control valve is located on the deck floor underneath the control panel or on the control panel attached to the hose reel.

Note: To determine if a US Jetting unit has a Jump Jet System, locate the high pressure hose connection on the top portion of the pump fluid head, refer to pictures of individual pump models in the Pump Section of this manual. US Jetting Radial Piston Diaphragm Pumps contain a dif-ferent style of Jump Jet System at the pump head but utilizes the same ON / OFF control valve. Refer to pictures in the RPD Pump Section of this manual.


Anti-Freeze System Sewer blockages occur no matter what the outside temperature is. In some cases, sewer lines can become clogged due to ground frost penetrating the ground below sewer pipes. In cases of frozen sewer lines, high pressure sewer jetting is the only method to clear the blockage. High pressure sewer jetting work is performed year-round, thus necessitating the need for special procedures to complete work in cold weather environments. Mobilizing high pressure jetting equipment to the work site in extreme cold conditions require certain precautions to protect expensive equipment and maintain operator safety. Water is a liquid when the temperature is above 32 Farenheit or 0 Centigrade. Water becomes a solid or ice when the temperature is 32 Farenheit or 0Centigrade or below. No matter how strong or powerful a high pressure jetting unit is, it cannot pump ice. Formation of ice within a high pressure jetting unit can cause expensive structural pump damage from water expansion during the freezing process. This damage can occur with the engine OFF. Additional pump damage can occur while attempting to start a frozen high pressure jetting unit if operators are not attentive. Operators need to be aware of added precautions needed when operating high pressure jetting units in cold weather ap-plications and take special precautions to pre-vent equipment failure. Water (normally) cannot be completely drained from a high pressure jetting unit, es-pecially units that contain a high pressure hose coiled on a reel. Water trapped inside of a high pressure jetting unit can freeze when exposed to cold weather causing severe and expensive damage. A high pressure jetting unit cannot be used if water has frozen within the system. The US Jetting Anti-Freeze System allows for the high pressure jetting unit to be util-ized in cold weather environments. The Anti-Freeze system contains a 19 gallon Anti-Freeze solution tank integrated into the units piping system, isolated by a single shut-off valve. When properly used, the Anti-Freeze solution can be used for cold weather protection and recovered (stored within the unit) for use at a later time. The Anti-Freeze system eliminates the need for cumbersome storage containers and reduces the possibility of accidental spillage.


Anti-Freeze System US Jetting Anti-Freeze Systems are available as optional equipment on trailer mounted units, skid units, truck units, enclosed truck units and enclosed trailer units for use with all models of the US Jetting high pressure pump product line (individual com-ponent mounting location may vary on different unit models). The concept of Anti-Freezing a high pressure jetting unit is the displacement of any remaining trapped water within the high pressure jetting unit with an Anti-Freeze solution. When removing or purging the Anti-Freeze from the unit, capturing of the Anti-Freeze solution is just as important for both eco-nomical and environmental reasons. Always use propylene glycol based Anti-Freeze or RV (recreational vehicle) Anti-Freeze. This type of Anti-Freeze is commonly available at Wal-Mart stores under the brand name Dow RV & Ma-rine Anti-Freeze. Automotive or glycol based Anti-Freeze can be used but is not recom-mended due to environmental concerns and liability. At the beginning of the cold weather season an initial batch of Anti-Freeze should be prepared for use and re-use throughout the winter season. Each time the Anti-Freeze solution is used and recovered, a small amount of additional water is introduced thus diluting the potency of the Anti-Freeze solution and raising the freezing point. Periodic checks of the Anti-Freeze solution must be performed to insure the appropriate Anti-Freeze concentration for cold weather protection.

NOTE: Only environmentally friendly propylene based Anti-Freeze should be used. Never use a glycol based or automotive type Anti-Freeze due chemical toxicity. To conform to OSHA regulations for worker awareness, always obtain a MSDS sheet for the brand of Anti-Freeze used for proper use and disposal of propylene based Anti-Freeze and Anti-Freeze solutions.


Anti-Freeze System Important Tips For Anti-Freezing Units:

Whenever Anti-Freezing or purging Anti-Freeze from the high pressure jetting unit, always operate the engine at an idle speed and manually operate water control valve.

DO NOT USE Gen II Wireless Remote Control System, ei-ther the Handheld or Foot Activated controllers; operate the unit from the control panel.

The engine will be started and shut-off during the Anti-Freeze process to control the flow of water and Anti-Freeze solution. The water control valve will be left in the ON position or high pressure setting during most of the Anti-Freeze process.

Never Anti-Freeze a high pressure jetting unit with a nozzle or drain jet extension attached to the end of the high pressure jetting hose

Installing Anti-Freeze Solution For Cold Weather Protection:


Anti-Freeze System

Read Thoroughly Before Starting To Anti-Freeze Unit For initial or beginning of season use:

Note the level of Anti-Freeze within the tank using the sightglass tube mounted on the side of the Anti-Freeze tank. If the tube is dirty, remove and clean. It is important to be able to distinguish fluid color & level throughout the winter season. If necessary, clean & flush the Anti-Freeze tank prior to use at the beginning of the season. Note: For future reference that the level in the sightglass, this will be the minimum fluid amount required to Anti-Freeze the system.


Anti-Freeze System Regular installation of Anti-Freeze solution: 1. Confirm that the Anti-Freeze tank valve is in the closed position. 2. Pour 5 gallons of undiluted, pure propylene based Anti-Freeze into the Anti-Freeze

tank 3. Obtain two 5 gallon open top pails, pre-position between the hose reel and control

panel. 4. Remove nozzle and drain jet extension from end of high pressure jetting hose if

present. 5. Remove / open the Anti-Freeze tank fill cap. Always remove the Anti-Freeze tank

cap when Anti-Freezing the system or purging Anti-Freeze from the system. 4. Open water storage tank drain valve. 5. Open the tank shut-off valve. 6. Allow all water to drain from water storage tank. 7. Remove the water filter cup to empty then replacehand tighten only 8. Close the tank shut-off valve. 9. Close the main drain shut-off valve. 10. Note level in sight tube, is there enough Anti-Freeze or Anti-Freeze solution to con-

tinue? Tank level should have a minimum of 4 of Anti-Freeze solution to complete the process.

11. Open the Anti-Freeze tank valve. 12. Open pump bleed valve slightly to remove air from system, close when done. 13. Remove nozzle from high pressure jetting hose. 14. Place end of hose in five gallon pail. 15. Set water selector valve to ON position. If unit is equipped with GEN II Wireless re-

mote Control System, turn key to the ON position then turn water selector knob to


Anti-Freeze System ON. Allow time for the actuator to activate the water control valve to the ON posi-tion.

16. Set engine throttle to idle. 17. With one hand, hold end of high pressure jetting hose over one the 5 gallon pails. 18. Start engine. 19. Fill one 5 gallon pail to fill with water and then switch to fill second pail halfway

(about 7 gallons total), then shut-off the engine. Do not shut-off water control selec-tor valve. If the Anti-Freeze solution or colored water appears, shut-off the engine immediately.

20. Connect high pressure hose to Return to Anti-Freeze Tank line connection and tighten connection with a wrench.

21. Note level of Anti-Freeze on tank sightglass. 22. Re-start engine to allow water and Anti-Freeze solution to mix until a uniform color

is achieved. Jetting unit is now in a closed loop, allowing any residual water to mix with Anti-Freeze.

23. Allow engine to run at idle for two minutes for proper circulation and to complete the next two procedures.

24. Briefly (2 seconds) open By-Pass Valve then close. 25. Briefly ( 4 seconds) turn the Jump-Jet valve ON then turn back to the OFF position. 26. Briefly (4 seconds) turn the water selector valve OFF then turn back to the ON po-

sition. 27. Turn the OFF Engine 28. Open the tank shut-off valve to allow a little Anti-Freeze to leak into the water tank

connection tube. This allows the Anti-Freeze solution to protect both sides of the shut-off ball valve.

29. Using a small container, open main drain valve to obtain a sample for testing with an Anti-Freeze Coolant Tester. Anti-Freeze should be in the proper range. After testing, pour the test sample back into the Anti-Freeze tank.

30. If the Anti-Freeze solution has been diluted, drain off 4 gallons of Anti-Freeze solu-tion and properly discard. Add 4 gallons of new undiluted, pure propylene based Anti-Freeze into the Anti-Freeze tank. Repeat Anti-Freeze procedures from Step 22.

31. Replace the vented Anti-Freeze tank cap. 32. Anti-Freeze operation is completed.

Note: If the US Jetting unit contains dual high pressure hose reels, each hose reel will need to have Anti-Freeze circulated through the reel. Fol-low the directions for Anti-Freezing the first hose reel. Set high pressure jetting unit to activate second hose reel, switch diverter valve. Follow pro-cedures 12 to 33 to Anti-Freeze the second hose reel. For units with dual high pressure hose reels, it is recommended that only one hose reel be

purged of Anti-Freeze for use at a time. The other hose reel should contain Anti-Freeze when not in use to prevent freezing.


Anti-Freeze System To Purge and Recover Anti-Freeze From The Unit For Reuse: Read Thoroughly Be-fore Starting To Anti-

Freeze Unit 1. Remove / open the Anti-

Freeze tank fill cap. Al-ways remove the Anti-Freeze tank cap when Anti-Freezing the system or purging Anti-Freeze from the system.

2. Note the Anti-Freeze so-lution level in the sight-glass. If the sightglass indicates a high fluid level of above two-thirds of a tank, it may be necessary to drain off some Anti-Freeze solution to pre-vent the Anti-Freeze from overfilling the tank. Anti-Freeze solution can be drained into a container or pail through the main tank drain valve.

3. Fill water tank with water. Removal or purging of Anti-Freeze can begin when tank contains about 30 gallons of water.

4. Detach the high pressure hose from Return To Anti-Freeze Line connector. 5. Place hydraulic reel control valve in the detent or free spin position (locked in the

down position) and manually pull off +/- 20 feet of hose. 6. Insert the end of the high pressure jetting hose into the top of the Anti-Freeze tank.

Allow for two feet of the hose to remain inside the tank. 7. Close shutoff valve at base of Anti-Freeze tank. 8. Open shutoff valve between water tank and water filter. 9. Open (briefly) pump prime valve to determine if pump is frozen. Water or Anti-

Freeze solution may come out or air may be sucked into the system, either is an indication the pump is not frozen.

10. Set water selector valve to the ON position. If unit is equipped with GEN II Wireless


Anti-Freeze System Remote Control System, turn the ignition key to the ON position then turn water se-lector knob to the ON position. Allow time (5 seconds) for the actuator to activate the water selector valve to the ON position.

11. Start the engine and then proceed immediately to grasp end of high pressure hose located in Anti-Freeze tank. Use two people to complete this task if available.

12. Slowly remove the high pressure jetting hose from the Anti-Freeze tank until the water stream (colored due to the presence of Anti-Freeze) is visible while maintain-ing the colored water flow into the Anti-Freeze tank. A one inch gap between the end of the hose and the Anti-Freeze tank fill spout is acceptable.

13. When colored water flow changes to clear water, remove water flow from entering the Anti-Freeze tank, allow water to spill on the ground.

14. Shut water flow OFF at the water control valve. If unit is equipped with GEN II Wire-less Remote Control System, turn water selector knob to the OFF position. Allow the engine to continue to run at an idle.

15. Continue to allow water to fill water tank until full. 16. The unit is now ready to operate for high pressure jetting work. In severe cold environments (below 32 Farenheit or 0Centigrade), operators should be aware of potential hazards and other factors & conditions that could result in a frozen high pressure jetting unit. When not jetting, allow the engine to idle so water will circulate through the unit and

not freeze. Turning the engine OFF can result in localized freezing of components that will prohibit use of unit until thawed.

Always test for unrestricted water flow (without an attached nozzle) through high pressure jetting hoses (including Mini Jet or Micro Jet hose kits) prior to attaching a nozzle to the high pressure jetting hose).

Do not lay high pressure hose on the ground. If unavoidable, flush water through the hose periodically to prevent an ice blockage by quickly turning the water control valve ON and OFF. Hoses that lay on the ground without water moving through the hose can freeze in minutes.

Periodically turn the Jump Jet Valve ON then OFF to prevent Jump Jet lines from freezing.

Never use the high pressure water to clear ice blockages from within a frozen high pressure jetting hose including Mini Jet or Micro Jet hose kits. Ice blockages dis-lodged by high pressure water can shoot from the high pressure hose as deadly projectiles. If a high pressure jetting hose does freeze, stop work immediately. Drain all water from the water storage tank (open main drain shut-off valve), with the engine running and the water selector valve in the return to tank position. After all the water has drained from the tank, close the tank shut-off valve and the main drain shut-off valve. Open the Anti-Freeze tank shut-off valve and allow Anti-Freeze to enter the pump. With the water selector valve in the dump or re-circulate posi-tion, the Anti-Freeze solution will go directly into the water storage tank. This will


Anti-Freeze System provide freeze protection for the high pressure pump, water filter and other system components. The unit should be placed in a warm garage to allow the high pres-sure hose to thaw before being used again.

Be aware of ice formation from water leaving the high pressure jetting unit that may cause slip or fall hazards for operators, workers or passersby.

If a high pressure jetting unit or any compo-nent has been exposed to cold weather that resulted operational failure due to freezing, extreme care must be used when operating the unit after thawing. Operators must check for any signs of damage from a freeze - thaw cycle. All damage from a freeze thaw cycle must be repaired before using the high pressure jetting unit.

Location of the Flow By-Pass Valve is

always adjacent to Water Selector Valve. Arrow on valve indicates relative

position only.

Most US Jetting High Pressure Jetting units include a Water Flow By-Pass valve for fine tuning of water pressure and flow adjustments as needed with certain jetting noz-zles and reduced diameter accessory hose kits. Water Flow By-Pass valves are avail-able in two different styles, one with a black knob and the other with a tee handle. Al-though different in appearance, both are equal in function & pressure ratings. US Jetting manufactures and ships high pressure jetting units with standard size noz-zles with precision drilled nozzle orifices to provide maximum pressure and water flow to complement each unit. Use of the standard size nozzles will allow the unit to operate at 4,000 PSI at full engine power with the Water Flow By-Pass Valve in the closed po-sition. Use of nozzles by other manufac-turers that do not precisely match unit specifications (i.e. correct pres-sure with reduce water flow) or use of smaller diameter hose cleaning kits may require opening the By-Pass valve to reduce pressurized water flow to prevent over-pressurization and rupture of pres-sure relief disc. Water Flow By-Pass Valves allows the operator to divert excess pres-surized water flow to the water tank

Water Flow By-Pass Valve


Flow By-Pass Valve while maintaining overall precise pressure control within the system. Use of the Flow By-Pass allows the Operator to better control and set desired operating pressure in ad-dition to the engine throttle. Use of the Flow By-Pass Control Valve prevents poor en-gine performance or engine loading at low engine speeds. When using the Flow By-Pass Valve, it is best to open the valve a quarter turn, raise engine RPMs then adjust to the desired pressure by adjusting the Flow By-Pass valve to the desired pressure.

CAUTION: When using reduced diameter accessory hose kits such as the Micro Mini-Jet and the Mini-Jet kits, the Flow By-Pass Valve should be opened a quarter of a turn (counterclockwise) to prevent pump over-pressurization and reduce engine loading at low engine speeds. This is always true when using Micro Mini-Jet kits that have the smallest internal hose diameter. Failure to partially open the Flow By-Pass Valve may result in the unnecessary rupture of the pressure relief disk.


Colored Safety Leader Hose All US Jetting High Pressure Jetting units configured for use in sewer and drain clean-ing applications should always have a 10 safety colored leader hose attached to the end of the primary jetting hose. The Colored Safety Leader Hose is rated for the same or greater pressure than the main sewer jetting hose. This serves multiple purposes, such as:

Acts as a safety indicator to warn to the operator the nozzle (and its high pressure water stream) is less than 10 feet from the entry point of the pipe by the visible color change .

Acts as a sacrificial piece of hose that is suscepti-ble to abrasive wear from the water and debris stream from the nozzle, thus protecting the integ-rity and length of the main jetting hose

The Colored Safety Leader Hose should be left attached to the main jetting hose at all times for operator convenience. The Colored Safety Leader Hose should be secured to the main hose with teflon tape and secured with wrenches to eliminate pressure and water leaks.

Colored Safety Leader Hose & Tiger Tail Hose

Protector Should Always Be Used For

Sewer & Drain Cleaning Operations.


Tiger Tail Hose Protectors Tiger Tail Hose Protectors should always be used to prolong the life of the high pres-sure jetting hose. Tiger Tails provide a smooth surface for the jetting hose when transi-tioning the bend at the bottom of the manhole or at pipe entry point. This prevents the hose from gouging and resulting coating peeling. Tiger Tails are available in three di-ameter sizes; 3, 2 and 1-1/2. Tiger Tails should be used whenever possible and in-cluding use with smaller diameter hose kits. All Tiger Tails have a length of nylon rope attached so the Tiger Tail can be secured to the jetting unit to prevent movement or loss.

Not Using Tiger TailsImproper jetting

method of line clean-ing can cause hose

damage and unnecessary hose

wear.

Tiger Tail Hose Protectors can be used in various places to reduce friction wear on high pressure jet-ting hose.

All high pressure jetting units should have at least two Tiger Tail hose protectors for special applica-tions.

Daily & Monthly Equipment Checklist Located on the rear corner of the unit is a durable graphic decal to remind and prompt operators of the daily and monthly maintenance checks to be performed. Items to be checked on a daily basis are written inside rectangular boxes with a line indicating the area or component to be inspected. Items listed inside of black filled boxes with white text require inspection on a monthly basis. Operators should always observe the unit for any problems that may occur during normal operations between inspection inter-vals.

Daily Equipment Check Check High Pressure Jetting Hose & Safety Colored Leader Hose Unit should always have a safety colored leader hose. Operators should check the condition of the safety colored leader hose for wear, cuts or other types of damage. The visible portion of the main jetting hose should also be checked. If any hose dam-age is discovered, repairs or replacement should be made before use. Trailer Lights Turn - Tail Stop Once the unit is connected to the tow vehicle, a check of the trailer lighting system should be performed. Inspection should also include any damaged light lenses. A test of the directional arrowboard should also be performed at this time. If any faults are discovered, repairs should be made before use.


Raise Leveling (2) Stand For Transport (Option) This simple procedure is often overlooked by operators, failure to check leveling stand position can result in severe damage to the unit. Operators need to check both sides of the units for elevated leveling stands not only at the beginning of every shift but also when relocating from one worksite to another. Check Tire Inflation 50 PSI (4) Daily tire inspection should be performed to check tire air pressure and the condition of the tires. Worn tires and tires with cuts or blisters should be replaced before use. Bleed Brake Air Tank A petcock located under the air tank should be opened to allow accumulated moisture to be drained from the brake system. This procedure should be performed when the brake air lines are connected and under pressure. Escaping air should be heard when the valve is opened. Check for Proper Color Safety Disc Inspection should be performed to visually see if the proper color high pressure rup-ture disc (white is for 4000 PSI) is correctly installed. Never use the machine if the plastic disc has been replaced with some other type of round disc or if the disc holder has been capped off or removed and plugged. Clean & Check Water Filter Remove and inspect the water filter mesh element. Clean and remove any dirt or de-bris. Check the filter mesh for damage. Replace mesh in filter cup, re-install on ma-chine, hand tighten only. Dirt and debris accumulates on the inside of the wire mesh filter, filter must be removed from clear protective cup for inspection. Check Pump Oil Level Oil level should be visible through sight glass with level passing through the red dot. Add oil if required (SEE CHART). Check Fuel Filter Transparent fuel filter should be checked daily for signs of debris or water. Service, re-place filter as necessary. Check Brake Fluid Level Remove cap to inspect flui
