STEP 6Before cutting, check for proper tension by pulling the chain around the bar by hand. If you cannot easily pull by hand, the chain is too tight and needs to be loosened slightly. CAUTION: Be aware that the guidebar rails may develop sharp edges over time so always pull the diamond chain by the diamond segments.

STEP 5Make sure all the drive links are inside the guidebar groove then lift the bar nose and tension the chain by turning the screw clockwise.

CORRECT CHAIN TENSIONAll chains have a tendency to stretch when used. Diamond chains stretch more than wood cutting chains because of the abrasive materials they are cutting. If the chain is too tight, a lot of the saw's power goes into turning the chain rather than into the cut. In extreme over-tightened cases, the saw may not be able to turn the chain at all. In addition, damage can occur to the bar nose and premature stretch may occur.

CHAIN TOO LOOSEIf the chain is too loose, it could come off the bar, or it will allow the drive sprocket to spin without turning the chain, which can chew up drive links. When a chain stretches to a point where the drive links are hanging approximately 1/2 in (12 mm) to 3/4 in (18 mm) below the bar, it is time to tension the chain.

IMPORTANT A properly tensioned chain will optimize cutting performance. The tensioning rule of thumb for a concrete cutting chain saw is that a properly tensioned diamond chain must not be bowstring tight and can be pulled freely around the guide bar by hand easily without binding.

PROPER CHAIN TENSION If the chain is too loose, it could come off the bar, or it will allow the drive sprocket to spin without turning the chain, which can chew up the chain drive links. If the chain is too tight, a lot of the saw’s power goes into turning the chain rather than into the cut. In extreme over-tightened cases, the saw may not be able to turn the chain at all. In addition, damage can occur to the bar nose and premature stretch may occur.

HOW TO CHECK Before cutting, check for proper tension by pulling the chain around the bar by hand. If you cannot easily pull by hand, the chain is too tight and needs to be loosened.

WHEN TO TENSION All chains have a tendency to stretch when used. Diamond chains stretch more than wood cutting chains because of the abrasive materials they are cutting. When a chain stretches to a point where the drive links are hanging approximately 1/2 in- 3/4 in (12 - 18 mm)below the bar, it’s time to tension the chain.

HOW TO TENSION To tension the chain, first loosen the side cover nuts, then while holding the nose of the bar up, use a screw driver to turn the tensioning screw clockwise until the chain drive links hanging below the bar are just beginning to enter the bar groove. Continue to hold up on the nose of the bar and firmly tighten the side cover nuts, (20 ft-lbs, 27 Nm). And remember, it’s the side cover nuts that hold the bar in position.

HOW TO PREVENT CHAIN TENSIONER BREAKAGE Do not attempt to adjust the tensioner without first loosening the side cover nuts. Do not use the saw without making sure the side cover nuts are tight. If the side cover nuts are not tight, the bar can slip backwards during cutting and break the tensioner pin.

Proper Chain TensionIf the chain is too loose, it could come off the bar, or it will

allow the drive sprocket spin without turning the chain which can damage the chain drivel inks. If the chain is too tight, much of the saw’s power goes into turning the chain rather than into the cut. In extreme over-tightened

cases, the saw may not be able to turn the chain at all. In addition, damage can occur to the bar nose and

premature chain stretch may occur.

How To CheckBefore cutting, check for proper tension by pulling the

chain around the bar by hand. If you cannon easily pull by hand, the chain is too tight and needs to be loosened.

When to TensionAll chains have a tendency to stretch when used.

Diamond chains stretch more than wood cutting chains because of the abrasive materials they are cutting. When

a chain stretches to a point where the drive links are hanging approximately 1/2 inch to 3/4 inch below the

bar, it’s time to tension the chain.

How to TensionTo tension the chain, first loosen the side cover nuts, then while holding the nose of the bar up, use a screwdriver to turn the tensioning screw clockwise until the chain drive links hanging below the bar are just beginning to enter

the bar groove. Continue to hold up on the nose of the bar and firmly tighten the side cover nuts. And remember, it’s

the side cover nuts that hold the bar in position.

How to Prevent Chain Tensioner BreakageDo not attempt to adjust the tensioner without first

loosening the side cover nuts. Do not use the saw without making sure the side cover nuts are tight. If side cover nuts are not tight, the bar can slip backwards during

cutting and break the tensioner pin.

Concrete cutting chainsaws require water for cooling and flushing the cut. Water is not as good as oil as a lubricant. Also, there are concrete particles mixed in with the water. As a result, sometimes the drive links do not nest properly on the drive sprocket. When this happens, the chain acts like it got tighter. There seems to be


tight spots and loose spots as you pull the chain around the bar. If you tension when the chain is in one of the loose spots, it will be too tight at some point in it’s rotation around the bar.

Rotating the chain completely around the bar by hand will let you know you have the chain properly tensioned.

AddITIONAl TENSIONING TIPS:

Concrete and ductile iron cutting chainsaws operate with looser chain tension than wood chainsaws. It is common, especially on gas powered, concrete cutting chainsaws to have the drive links hang completely out of the bar. Wood cutting chainsaws use oil to lubricate the chain. The oil makes the chain very slippery and allows the drive links to fully nest between the teeth of the drive sprocket. Concrete and ductile iron cutting chainsaws require water for cooling and flushing the cut. Water is

not as good as oil as a lubricant. Also, there is debris mixed in with the water. As a result, sometimes the drive links do not nest properly on the drive sprocket. When this happens, the chain acts like it

got tighter. There seems to be tight spots and loose spots as you pull the chain around the bar. If you tension when the chain is in one of the loose spots, it will be too tight at some point in it’s rotation

around the bar. Rotating the chain completely around the bar by hand will let you know you have the chain properly tensioned.

Additional Tips1. To reduce chain stretch and tensioning downtime, a minimum water suply should be used: - For ductile applications, a pump sprayer is sufficient. - For concrete applications us 20 psi or greater water pressure.2. Oil the chain at the end of the day to prevent rust but be careful not to over tension in this condition.3. When pulling the chain around the bar by hand, be careful not to touch the bar with thumb or forefinger. The bar rails can be very sharp. Grab only yhe diamond segments to pull the chain.The bar rails can be very sharp. Grab only the diamond segments to pull the chain.4. Always turn the engine off before tensioning the chain.

Pipe Clamp


Pipe Clamp Mounting Instructions

1. Assess pipe and area to cut. Ensure the chain saw will pass freely around any objects in and around the path of the cut. (ie: power lines, telecommunication lines, rocks, tools, etc.)

2. Ideally the pipe clamp should be mounted in a position that allows the locking pliers to be on the top side of the pipe. This will allow for easier clamping.

3. US Saws recommends a bottom up cutting process. This allows two safety functions.

a) With a bottom cut, a pipe will not sag in a fashion that will pinch the bar. A top cut could cause pinching as a pipe sags. b) The saw will be pulled through the cut by the operator and the bar will swing away from the operators position. If the tool is pushed (downward cut) the saw swings towards the operator.4. Mount the receiver at a 10 o’clock position. This will allow the saw to hang in a

near vertical orientation.

5. Slide mounting pin on the saw (see pin installation instructions) into receiver and install retainer clip.

6. Clear the area of loose debris that could get caught in the chain.7. Use the saw according to operating instructions. Light pressure applied to the handles is all that is required. Do not use levers, hang, or try to increase leverage on the tool.8. In some cases stopping your cut just before completion and leaving a tab allows

greater stability while making cuts down-line. Finish final cut freehand from the top to complete removal of section.

Pipe ClampReciever Pin Mounting Instructions

11

• Remove the rear bar stud nut.• Install pin on rear bar stud.• The inner thread of the pin will take the place of the nut.• In certain applications (larger than 10” pipe) the mounting pin

may need to be relocated to the front bar stud for greater saw clearance.

• Ensure the chain is adjusted according to the chain tensioning guide.

Read and understand instructions provided with the saw and/or pipe clamp before using this device. Use caution not to drop saw or strike mounting pin as damage to the chain tensioning mechanism can occur.

COLD ENGINE STARTING PROCEDURE 1. Pull the choke lever out, which also sets the throttle lock. 2. Depress primer bulb approximately 5-10 times. 3. Push in decompression valve. 4. Open the water valve 1/4 turn. 5. Place the saw on stable ground making sure the chain

is free of any obstructions. 6. Place foot on the base of the rear handle, and place one hand

on front handle. 7. With opposite hand, slowly pull starter handle until the

starter pawls engage. 8. Pull the starter cord (hard, fast, short pulls)

until engine initially fires or "pops". Could be as many as 10-15 pulls.

9. Push the choke lever in. 10. Pull the starter cord until engine starts - should be 1 to 2 pulls. 11. Release the throttle lock by momentarily squeezing on the

throttle trigger.12. When the engine starts, allow the engine to idle briefly.

Squeeze the throttle trigger several times to help warm up the engine.

13. Open the water valve completely.

CAUTION

STARTING AND STOPPING A CONCRETE CHAIN SAW

Never start a concrete chain saw without the bar, chain and side cover properly assembled. Failure to do so may result in serious injury.

Always move a concrete chain saw at least 10 feet (3 m) away from the fueling area before starting.

Place the saw on clear ground. Ensure that secure footing is established and chain is not contacting any objects. IMPORTANT

WARNING

WARM ENGINE STARTING PROCEDURE 1. Use the same procedure as starting a cold engine, but pull choke lever out, and then push back in to set

the throttle lock. If choke is used on a warm engine, the carburetor will flood with gas. 2. If the engine does not start in 3 hard, fast pulls with the throttle locked, fully squeeze and hold the trigger

while pulling the starter cord 3 more times. Note: To hold the trigger fully open it may be necessary to insert right foot into rear handle opening and twist.

STOPPING THE SAW• To turn the engine off, push stop switch to the "STOP" position. Close water valve.

PRE-CUT CHECKLIST

• Ensure proper chain tension: The chain should be easily pulled around the guidebar by hand.

• Ensure all safety devices are properly mounted and functional and that all controls are in proper working order.

• Be sure there are no obstructions (plumbing, electrical conduit, air ducts) and no unnecessary people present.

• Always wear protective clothing, including hard hat, eye protection, hearing protection, non-slip safety boots, and gloves. Avoid wearing loose fitting clothing.

• Adequate Water Supply and Pressure: Minimum Flow: 2 gpm (8 lpm) Minimum Water Pressure: 20 psi (1.5 bar)

• Diamond chains with SealPro® require a minimum water pressure of 20 psi (1.5 bar).

PLANNING THE CUT

• Select the proper chain type for the material being cut.

• Outline the cut with a permanent marker for a visual cutting guide.

• Avoid pinching the guidebar and chain. Always cut the bottom of an opening first, then top, and then the sides. Save the easiest cut for last.

• For the straightest cuts use the “Step Cut” method. First score the entire cut line approximately a half-inch deep using the nose of the bar. Next, deepen the cut by about two inches. Then plunge all the way through and complete the cut using the WallWalker®.

• Be sure cut concrete cannot fall and injure operator or bystanders. Concrete is very heavy, one cubic foot = 12 in x 12 in x 12 in = 150 lbs (30 cm x 30 cm x 30 cm = 68 kg).

• Check for and remove any obstructions (plumbing, electrical conduit, air ducts, etc,) that may interfere with the cut.

The single most important factor an operator can control to increase chain life is to use adequate water pressure. Insufficient water supply will result in excessive wear to the chain, which can lead to loss of strength and chain breakage, and/or damage to the guidebar nose sprocket.

IMPORTANT

OPERATION

Never start a diamond chain saw without the bar, chain and side cover properly assembled. Failure to do so may result in serious injury.

Always check hose connections before turning on air compressor.

Hold saw with both hands and ensure the chain is not contacting any objects.

• Ensure Proper Chain Installation: Concrete chains should lead with the bumper segment into the cut. Ductile chains can be mounted in either direction.

• Ensure Proper Chain Tension: The chain should be tight but easily pulled around the bar by hand.• Ensure all safety devices are properly mounted and functional. Ensure all controls are in working order.• Be sure there are no obstructions (plumbing, electrical conduit, air ducts, etc.) and no unnecessary

people present.• Always wear protective clothing, including hard hat, eye protection, hearing protection, non-slip safety

boots, and gloves. Avoid wearing loose fitting clothing.• Use Adequate Water Supply and Pressure: Minimum Flow: 1gpm Recommended Water Pressure: 20psi • Use Proper Air Supply: Minimum PSI : 90 Minimum CFM: 90• Blow the air supply line clear before connecting to the saw. • Check oil level; if necessary, re-fill oiler with ice-free air tool oil.• The chain should travel away from the operator on the top side of the bar during operation.

Pre-Cut Checklist

The single most important factor an operator can control to increase chain life is to use adequate water pressure. Insufficient water supply will result in excessive wear to the chain which can lead to loss of strength and chain breakage and/or damage to the guidebar nose sprocket.

• Select the proper chain type for the material being cut.• Outline the cut with a permanent marker for a visual cutting edge.• Avoid pinching the guide bar and chain. Always cut the bottom of an opening first, then top, and then

the sides. Save the easiest cut for last.• For the straightest cuts in concrete use the “Step Cut” method. First, score the entire cut line approxi-

mately a half-inch deep using the nose of the bar. Next, deepen the cut by about two inches. Then, plunge all the way through and complete the cut.

• For the straightest cuts in pipe cutting applications cut from the bottom up using the Pipe Clamp.• Be sure that cut material cannot fall and injure operator or bystanders. • Check for live electrical wiring near the cut or in the concrete to avoid electrocution.• Check for and remove all obstructions (plumbing, electrical conduit, air ducts, etc.) that may interfere

with the cut. © 2010 ICS, Blount International Inc. Specifications are subject to change without notice. REV0611 F/N 545067

Before cutting, make sure the pipe is in a safe condition to be cut. Support the piece you are going to be cutting in such a way that the cut will remain open during the cut and when the cut is finished. Pinching the chain during the cut could cause chain breakage and could result in death or serious injury to the operator.

If using the pipe clamp accessory, the clamp must be attached in such a way that it does not move during the cutting operation and/or when the cut is finished. Unexpected movement of the clamp could cause the operator to lose control of the saw resulting in death or serious injury.


Making The CutAll concrete pipe cutting chain saws are considered specialty tools. The overall cutting speed is slower that some other types of cutting equipment. For this reason the correct time allocation should be made so that the operator has time to make the cut at a safe pace and not have to force the saw to try and increase production. Forcing the saw creates unneeded wear on chains, bars, and drive components. Additionally, long periods of exertion can cause operator fatigue which can increase the likelihood of injury.

When using the saw in a hand held fashion a slow rocking motion will provide the best cutting action. Alternating pressure from the front of the cut to the rear of the cut offers reliable results.

The saw will cut slower when cutting through rebar and other reinforced materials. Allow the saw to run at full speed and use light pressure. Pushing hard on the tool only increases chain wear and stretching force adding to wear and increasing the cost per cut.

When cutting ensure that the water supply is sufficient for the cut being made.1. Connect all fittings (Air, Hydraulic, Water).2. Turn on power supply.3. Turn on water valve on the saw.4. Once water is running through the bar apply and hold full throttle to begin cut.5. Use full throttle for the entire cut. Feathering the throttle makes the saw difficult to control.

With the saw engaged in any surface the operator should be aware that the forces generated by the tool can force debris to be ejected from the moving chain either away from the saw or towards the operator. Ensure no bystander is located immediately in front of or behind the material being cut.

Troubleshooting

• SLOW CHAIN SPEED - Be sure the compressor is providing the correct air pressure, 90 psi, and cubic feet per minute, 90 cfm. These are the minnimum requirements; ideal performance can be achieved at higher volume.

• POOR CUTTING PERFORMANCE - Diamonds may be “glazed over”. Make a few cuts in abrasive material such as cinder block to expose diamonds. In the case of the pipe cutting chain, the segment does not wear away. However, the diamonds will wear away leaving a smooth surface.

• PREMATURE CHAIN STRETCH - Not enough water pressure. The recommended water pressure is 20 psi. Do not force the chain. Extra force will cause the chain to stretch faster.

• CHAIN TENSIONER BREAKAGE - Side cover nuts are not tight enough.

• WATER NOT FLOWING - Water hose is kinked, blockage in guide bar water ports, or water supply is not turned on.

• MOTOR DOES NOT START - • Insufficient air supply. Check compressor and air hose, valves, and air inlet

screen for blockage.• Chain tension is too tight. Loosen chain tension.• Iced exhaust. Wait until ice thaws, then lubricate with ice-free air tool oil.• Vanes sticky. Apply lubricant directly to saw air inlet and blow motor clear. Repeat

if necessary.

Maintenance

Air Motor Maintenance

Only proper maintenance can ensure consistent saw performance, reduction of wear, and thus, a reduction in operation costs and an increase in service life.

Service life and performance of the chain saw are determined by:1. Degree of air purity2. Lubrication3. Maintenance

System Clean-Up 1. Run saw, with water on, for 15 seconds out of cut to flush slurry and/or debris from chain, bar, and drive. 2. Wash concrete slurry, cutting debris, and/or ductile shavings from saw assembly. 3. Remove bar and chain. Flush out chain tensioner assembly location with high water pressure, then lube with grease. 4. Clean all air fittings on saw and compressor. 5. When finished cleaning saw, spray entire saw, chain, bar, and drive sprocket with a light weight penetrating oil (ie: WD40). This will minimize rust and reduce build-up on saw assembly.
