SAFE OPERATION

The best insurance against accidents is to abideby the safety regulations.Read and understand this section carefully,before operating the excavator.Every user, however experienced, shouldcarefully read and understand this section andthose of the attachments and accessoriesbefore taking the excavator into operation. Theowner is obliged to inform the operators of theseinstructions in detail.Keep this manual in the toolbox.

1. BEFORE OPERATION1. Make yourself acquainted with the excavator

and be aware of its limits. Read thisoperator's manual carefully before startingthe excavator.

2. Obey the danger, warning and cautionlabels on the machine.

3. For your safety, ROPS (Roll-Over ProtectiveStructure) with a seat belt is installed.Always use seat belt when the machine isequipped with a ROPS.Do not modify structual members of ROPSby welding, drilling, bending, grinding orcutting, as this may weaken the structure. Ifany component is damaged, replace it. Donot attempt repairs. If ROPS is loosened orremoved for any reason, make certain allparts are reinstalled correctly. Tightenmounting bolts to proper torque.

4. The seat belt must be inspected regularlyand replaced if damaged.

5. Track can be set at the narrow width 700mmand the standard width 860mm.(for details see "OPERATION OF TRACKWIDTH CHANGE AND DOZER")Do not operate in narrow track width700mm, there is a risk of the excavatortipping over, always operate in standardtrack width 860mm, except to pass througha narrow space on even ground.

6. Do not use the excavator under theinfluence of alcohol, medication or othersubstances. Fatigue is also dangerous.

7. Check the surroundings carefully beforeusing the excavator or when attachmentsare being attached.

A Pay attention to the overhead clearance withelectric wires.

-3SAFE OPERATION

5. Make sure that the dozer is on the front side.(The dozer must be raised.) If the swingframe has been turned 180 , i.e. the dozeris, seen from the operator, "behind", then thetravel direction is opposite to the drivedirection of the levers (when activating thedrive lever forwards, the excavator, seenfrom the operator, will move backwards).

6. Do not run the engine in closed or badlyventilated rooms. Carbon monoxide iscolourless, odourless and deadly.

7. Keep all safety equipment and covers inplace. Replace damaged or missing safetydevices.

8. Precautions against tipping over. In order tosecure safe operation, keep away fromsteep slopes and embankments. Do notswing the bucket downwards. Lower thedozer during digging. Keep the bucket aslow as possible while driving upwards. Turnslowly on slopes. Do not keep the excavatornear the edges of trenches and banks, asthe earth can give way due to the weight ofthe excavator.

9. Watch out at all times where the excavator isbeing moved to. Keep an eye out forhindrances.

10.Keep enough distance from trench and bankedges.

C Safety for childrenTragedy can occur if the operator is not alert tothe presence of children. Children generally areattached to machines and the work they do.

11.Never assume that children will remainwhere you last saw them.

12.Keep children out of the work area andunder the watchful eye of anotherresponsible adult.

13.Be alert and shut your machine down ifchildren enter the work area.

14.Never carry children on your machine. Thereis no safe place for them to ride. They mayfall off and be run over or interfere with yourcontrol of the machine.

15.Never allow children to operate the machineeven under adult supervision.

16.Never allow children to play on the machineor on the implement.

17.Use extra caution when backing up, lookbehind and down-make sure area is clearbefore moving.

18.When parking your machine if at all possiblepark on a firm, flat and level surface; if not,park across a slope. Set the parkingbrake(s), lower the implements to theground, remove the key from the ignition andlock the cab door (if equipped) and chock thecrawlers or the wheels.

6. If the excavator is to tow another machine,the load must be smaller than the strength ofthe hook.

5. MAINTENANCEBefore doing maintenance work on theexcavator, place the machine on even solidground, Iower the attachments on the ground,stop the engine and release the cylinderpressure by actuating the levers. Whendismantling hydraulic parts, make sure that thehydraulic oil has cooled down sufficiently toavoid burns.Start maintenance work carefully, e.g. loosenscrews slowly so that oil will not squirt out.1. Before doing work on the engine, the

exhaust system, the radiator and thehydraulics, let the excavator cool downsufficiently.

2. Turn off the engine at all times when fillingwith fuel. Avoid spilling and over-filling offuel.

3. Smoking is prohibited while fuelling andhandling the battery! Keep sparks and fireaway from the fuel tank and battery.Flammable gases escape from the battery,especially during charging.

4. Do not use or charge the refillable typebattery if the fluid level is below the LOWER(lower limit level) mark. Otherwise, thebattery component parts may prematurelydeteriorate, which may shorten the battery'sservice life or cause an explosion. Check thefluid level regularly and add distilled water asrequired so that the fluid level is between theUPPER and LOWER levels.

5. Read and follow "STARTING WITH ANAUXILIARY BATTERY" in "OPERATIONOF THE ENGINE", when starting with anauxiliary battery.

6. To avoid short-circuiting the battery, alwaysremove the earth cable first and attach theplus cable first.

7. Keep a first-aid box and a fire extinguisher athand at all times.

8. Do not open the radiator cap before theradiator has cooled down sufficiently.First loosen the cap to the first stop andallow the system enough time to release theremaining pressure. Then loosen the capcompletely.

9. Leaking hydraulic fluid has enough pressureto penetrate the skin and cause seriousinjuries. Leakages from pin holes can betotally invisible. Do not use the bare hand forchecking on possible leakages. Always usea piece of wood or cardboard. It is stronglyrecommended you use a face mask or eyeprotection.Should injuries occur with leaking hydraulicfluid, contact a doctor immediately. This fluidcan cause gangrene or serious allergicreactions.

10.To avoid leakage of battery acid whichcontains heavy metals, do not throw thebattery away.

11.Observe all laws and regulations concerningthe disposal of used oil, coolants, solvents,hydraulic fluids, battery acids and batteries.

12.To avoid fire, do not heat the hydrauliccomponents (tanks, pipes, hoses, cylinders)before they have been drained and washed.

-6 SAFE OPERATION

13.Use a face mask or eye protection to protectthe eyes and respiratory system againstdust and other foreign particles.

14.Do not crawl under the excavator if theexcavator is only supported by the boomand arm or the dozer. The excavator can tipover or lower itself due to hydraulic pressureloss. Always use safety struts or otherappropriate supports.

15.KUBOTA uses no parts which are lined withasbestos. Do not use these kind of partseven if they can be installed.

16.Fire preventionExcavator and some attachments havecomponents that are at high temperaturesunder normal operating conditions. Theprimary source of high temperatures is theengine and exhaust system. The electricalsystem, if damaged or incorrectlymaintained, can be a source of arcing orsparks.The following fire prevention guidelines willhelp to keep your equipment up and runningefficiently and keep the risk of fire to aminimum.

A Blow off all accumulated debris near hotengine exhaust components such asturbocharger and exhaust manifold as wellas exhaust pipes and muffler morefrequently when working in severeconditions.

A Clean out all accumulated flammable debrissuch as leaves, straw, pine needles,branches, bark, small wood chips and anyother combustible materials from inside themachine belly pans or lower unit structuresas well as from area in proximity to theengine.

A Inspect all fuel lines and hydraulic hoses forwear or for deterioration. Replace themimmediately if they begin to leak.

A Examine electrical wiring and connectorsfrequently for damage. Repair any wiresthat are loose or frayed before operating themachine. Clean all electrical connectionsand tighten all electrical connections asnecessary.

A Inspect the exhaust system daily for anysigns of leakage. Check for broken pipesand muffler and also for loose or missingbolts, nuts and clamps. If any exhaust leaksor fractured parts are found, repairs must becompleted prior to operation.

8 OPERATION OF THE ENGINE

3. Pull the throttle lever all the way back. 4. Insert the key into the starter switch and turn

it to position "ON".

5. Turn the key to position "Preheat". (approx. 5 seconds)

6. Turn the key to position "Start" and releaseafter the engine has started; it willautomatically return to the position "ON".

7. Check if all alarm lamps have gone out.Should an alarm lamp still be lit up, stop theengine and check for the cause.

Malfunction Indicator (Quick Diagnosis)

Alarm Lamp "Battery Charge"This lamp lights up when there is a malfunctionin the electrical system. The lamp lights upwhen the key is in the "ON" position and goesout as soon as the engine starts.

Alarm Lamp "Engine Oil Pressure"This lamp lights up when there is an abnormalityin the engine oil circulation.It lights up when the key is in the "ON" positionand goes out as soon as the engine startsrunning. Should the lamp light up while theengine is running, check the engine oil level.

Alarm Lamp "Fuel Level too Low" This lamp lights up when the fuel level in the fueltank is lower than 2L. The lamp lights up forthree seconds to check the dead lamp when thekey is in the "ON" position while the engine isstopped. The lamp goes out when the key is in the"START" position while the dead lamp check islit.

Alarm Lamp "Water temperature warning"This lamp lights up if the cooling system gets introuble while the engine is running. The lamplights up for three seconds to check the deadlamp when the key is in the "ON" position whilethe engine is stopped. The lamp goes out when the key is in the"START" position while the dead lamp check islit. If the lamp stays on with the engine running,interrupt the operation and keep the engine atidling speed for about 5 minutes and then stopthe engine. Now check the following points.

(1) Check for cooling water shortage andleak.

(2) Check the fan belt for looseness.(3) See if the radiator is covered with mud

or dirt.

(A) "PREHEAT"(B) "OFF"(C) "ON"(D) "START"


BHourmeterThe hourmeter shows the total operating hoursof the excavator.

C Meter readingThe meter counts up 1 for one operating hour.The electric meter is still counting if the enginestops but the key is in the "ON" position.

BCheckpoints after Starting the Engine

After starting the engine, but before startingoperation, check following points:1. Put the throttle lever in the "LOW" position

and let the engine idle for approx. 5 minutes.This allows the engine lubricant to warm upand penetrate every part of the engine.

A This idling is usually called "Warm-up".2. Once the engine has warmed up, check:

12 EXCAVATOR OPERATION

EXCAVATOR OPERATION

CONTROL OBSERVATIONS DURING OPERATIONBStop the Engine immediately if:A Sudden increase or decrease in engine

revolution occurs.A Sudden abnormal noises occur.A Exhaust gases turn suddenly very dark.

Make following control observations duringoperation to be sure that everything functionsnormally.

BAlarm LampsShould an alarm lamp light up during operation,stop the engine immediately and as describedbelow, check for the cause. Do not use theexcavator when an alarm lamp is lit up.Explanation of alarm lamp is described as"Malfunction Indicator (Quick Diagnosis)" under"STARTING THE ENGINE" in "OPERATIONOF THE ENGINE".

Engine Oil PressureWhen the engine oil pressure sinks below theprescribed level, the alarm lamp will light up.Should this occur during operation and not goout even if the engine revolution is increased by1000 rpm, check the engine oil level. (see"Check Engine Oil Level" under "DAILYCHECKS" in "MAINTENANCE").

Battery ChargeIf the battery is not charged by the generator,the alarm lamp will light up. Should this occurduring operation, check the electrical system orcontact your KUBOTA dealer.(see "TROUBLESHOOTING")

RUNNING-IN OF THE NEW EXCAVATOR The operation and care of the new excavatorinfluences its life span. Your new excavator hasbeen carefully checked and tested beforeleaving the factory. In spite of this, all movablecomponents must run-in during the first 50work hours. Do not work with full revolution andfull loads during this period. It is most importantto run-in your excavator properly in order toachieve its full performance and longevity.During the running-in, the following pointsshould be adhered to in all cases.

BDo not Work with Full Revolutions or Full Loads during the First 50 Working Hours.

A Let the engine warm up sufficiently in thecold season.

A Do not let the engine rev-up more thannecessary.

BOil Change in the Run-in Stage. The lubrication oil plays a specially importantrole during the run-in phase of the excavator.The numerous movable parts are not yet run-in,so that many fine metal particles can developand cause damage or shorten the lifetime ofmany components. Pay attention to the oil-change intervals and execute them soonerrather than later as necessary. See the subject"Care and Maintenance" for more details on theoil-change intervals.

*NOTE:A See "SWIVEL MOVEMENT AND SWING

MOVEMENT".

OPERATION OF THE BOOMTo raise the boom, pull the attachment controllever back.The boom is equipped with a cushion cylinderwhich prevents excavated material in the bucketfrom fall-in out. By low hydraulic oil temperature,(e.g. right after starting the engine) thecushioning function will only be effected after acertain delay (approx. 3 to 5 seconds). Thiscondition results from the viscosity of thehydraulic oil and is no sign of a malfunction.

A When lowering the boom, make sure that itdoes not hit the dozer and that the bucketteeth do not touch the dozer.

OPERATION OF THE ARMPull back the left attachment control lever andthe arm will be pulled in. To move the arm out,push the control lever towards the front.

A When pulling in the arm, the movement maystop for a short moment when the arm is inits vertical position. This is caused by thefact that at this position the maximum loadfor the arm and bucket is reached, and thehydraulic pressure in the cylinder is not highenough. This is a characteristic of thehydraulic system and is not a sign of amalfunction.

OPERATION OF BUCKETTo dig with the bucket, move the rightattachment control lever from the neutralposition towards the left. Moving the controllever towards the right pushes the bucketoutwards and dumps its contents.


SWIVEL (UNIT SWING) OPERATION

To avoid personal injury: A When working in groups, always let

the others know what you are going todo before you do it.

A Keep away from the working area.

A Do not operate the left attachmentcontrol lever abruptly from the right tothe left (or vice versa). Because of the lawof inertia, this causes an impact load onthe swing gear and the swing motor.Additionally, the lifetime of the excavatorwill be shortened.

A Unlock the swing lock pin beforecarrying out swivel operations.

1. Tilt the control lever to the left and the upperstructure will turn to the left.

2. Tilt the control lever to the right and theupper structure will turn to the right.
