Read and heed carefully the safety instructions listed and follow the precautions recommended to avoidpotential risks and to safeguard your health and your safety.

THIS ALERT SYMBOL SIGNALS IMPORTANT MESSAGES INVOLVING YOUR SAFETY.

Most accidents, whether they occur in industry, on thefarm, at home or on the road, are caused by the failureof some individuals to follow simple and fundamentalsafety rules and precautions. For this reason MOSTACCIDENTS CAN BE PREVENTED by recognisingthe real cause and doing something aboiut it before theaccident occurs.Regardless of the care used in the design and construc-tion of any type of equipment, there are many conditionsthat cannot be completely safeguarded against withoutinterfering in the reasonable accessibility and efficientoperation.A carefull operator is the best insurance against anaccident. The complete observance of one simple rulewould prevent many serious accidents.The rule is simple: never attempt to clean, lubricate ormaintain a machine while it is in motion.

AVOID ACCIDENTS

WARNINGPrior to engaging in any maintenance, adjustmentor repair operation on machines having hydrauli-cally, mechanically, and/or cable controlled equip-ment (such as shovels, loaders, dozers, excavatorsetc.) be certain the equipment is lowered to theground.If it is necessary to have the equipment partially orfully raised to gain access to certain items, be surethe equipment is suitably supported by meansother than the devices used for controlling theequipment.

- NEVER COAST the machine down grades and slopeswith the transmission in neutral or neutralised.

Choose and shift into the most appropriate gear to keepthe speed required, thus preventing any loss of control.

- Do not operate machinery in a condition of extremefatigue or illness. Be especially careful towards the endof working shift.

- Do not operate machine with brakes out of adjustment.- Operate the machine at speeds slow enough to ensure

complete control at all times.

- Travel slowly over rough terrain, on slopes or near drop-offs, in congested areas or on ice or slippery surfaces.

- When backing, always look to where the machine is tobe moved. Be alert to the position of exposed personnel.DO NOT OPERATE if exposed personnel enter theimmediate work area. STOP THE MACHINE.

- Maintain a safe distance from other machines. Providesufficient clearance for ground and visibility conditions.Yield right-of-way to loaded machines.

- Maintain clear vision of areas of travel or work. Keep cabwindows clean and repaired.

- When machines are operating in tandem, the pusher(rear) must be equipped with the appropriate deflectorsto protect the unit in front from the air stream coming fromthe radiator.

- When pulling or towing through a cable or chain, do notstart suddenly at full throttle; take-up slack carefully.

Inspect carefully for flaws or troubles before using.

- Avoid kinking chains or cables. Do not pull through akinked chain or cable to the high stresses and possibilityof failure of the kinked area. Always wear heavy gloveswhen handling chains or cables.

- Be sure chains and cables are anchored and the anchorpoints are strong enough to handle the expected load.Keep exposed personnel clear of anchor points andcables or chains.

- DO NOT PULL UNLESS OPERATOR's COMPART-MENT OF MACHINES INVOLVED ARE PROPERLYGUARDED AGAINST POTENTIAL CABLE OR CHAINBACKLASH.

- Be alert to soft ground conditions close to newly con-structed walls. The fill material and weight of the machinemay cause the wall collapse under the machine.

- In darkness, check area of operation carefully beforemoving in with machine. Use all lights provided. Do notmove into area of restricted visibility.

- If engine has a tendency to stall for any reason underload or idle, report this for adjustment to proper mainte-nance authority immediately. Do not continue to operatemachine, until condition has been corrected.

- On machines supplied with suction radiator fans, be sureto periodically check engine exhaust parts for leaks, asexhaust fumes are dangerous to the operator.

- In case of closed type cabs, always keep an opening withthe outside, to ensure a constant air circulation.

- Operators must know thoroughly the performances ofthe machine they are operating. When working onslopes or near sudden level drops of the terrain, avoidareas where ground is loose or soft since rolling-over orloss of control of machine could result.

- Where noise exposure exceeds 90 dBA for 8 hours, wearapproved ear protection.

- When counterweights are provided, do not work ma-chine if they have been removed.

- Overtaking manoeuvres must be performed only whenabsolutely necessary and unavoidable. Beware of pos-sible uneven terrains, poor visibility conditions, the pres-ence of other machinery or persons out of sight.

- Operate the machine at a speed adequate to the workingconditions in the site and slow enough to ensure com-plete control at all times.

- Never use the machine as a work platform or scaffolding,nor other inappropriate operations (i.e. pushing railwaycars, trucks or other machines).

VSAFETY RULES

- Be alert of people in the operating area of the machine.

- When operating a machine, know in advance whatclearances will be encountered, overhead doors, ca-bles, pipes, bearing load limitations of ground, bridges,floors or ramps.

- When roading, find-out what conditions are likely to beencountered, clearances, traffic congestion, type of roadsurfacing, etc. Beware of fog, smoke or dust elementsthat obscure visibility.

- When crossing gullies or ditches, move at an angle withreduced speed after ensuring ground conditions willpermit a safe traverse.

- Explore the working area to identify potential risks suchas: slopes, overhangs, pits, demolition rubble, fires,ravines, ditches, soft terrain, heavy traffic, crowded park-ing areas, closed ambients. In such conditions, proceedwith extreme care.

- Whenever possible, avoid going over obstacles such asrough terrain, rocks, logs highly irregular ground, steps,ditches, railroad tracks. When obstructions must becrossed, do so with extreme care at an angle, if possible.Reduce speed, shift-down. Ease up to the break overpoint, pass the balance point slowly on the obstructionand ease down on the other side.

- In steep down-hill operation, do not allow engine to over-speed. Select proper gear before starting down grade.

- Avoid side hill travel, whenever possible. Drive up anddown the slope. Should the machine slipping sideways,turn it immediately downhill.

- The grade of slope you should attempt will be limited byfactors such as condition of the ground, load beinghandled, type of machine, speed of machine and visibil-ity.

- There is no substitute for good judgement when workingon slopes.

- Avoid operating equipment too close to an overhang orhigh wall, either above or below the machine. Be on thelook-out for caving edges, falling objects and slides.Beware of concealment by brush and undergrowth ofthese danger.

- When pushing-over trees, the machine must beequipped with proper overhead guarding. Never allowa machine to climb up on the root structure particularlywhile the tree is being felled. Use extreme care whenpushing over any tree with dead branches.

- When pushing trees with dead limbs, proceed withextreme care. Avoid brush piles, logs or rocks.

- NEVER DRIVE OVER THEM or other surface irregulari-ties that brake traction with the ground, especially whenon slopes or near drop-offs.

- Be alert to avoid changes in traction conditions that couldcause loss of control. DO NOT DRIVE on ice or frozenground conditions when working the machine on steepslopes or near drop-offs.

- Working in virgin and rough terrains is characterised bythe presence of all the perils and risks listed above. Inthese conditions, it is emphasised the danger repre-sented by large tree limbs (possibly falling on the ma-chine), large roots (acting as a leverage under themachine when up-rooted causing the roll-over of theunit) etc.

STOPPING

- When the machine is stopped for whatever reason,follow the instructions of chapters "Stopping the ma-chine" and "Stopping the engine" of the Operation andMaintenance Instruction Manual.

- Always remember to position the transmission drivecontrol in neutral and engage the control lock to securethe machine.

- The parking brake is automatically set, when the trans-mission safety lever is lowered.

- NEVER LEAVE THE MACHINE UNATTENDED with theengine running.

- Always, before leaving the operator's seat and aftermaking sure all people are clear of the machine, slowlylower the attachments or tools flat to the ground in apositive ground support position.

- Return the controls to rest position. Place the gearshiftlever in neutral. Disconnect the master switch and ex-tract the key.

- Park in a non- operating and no-traffic area or as in-structed. Park on firm level ground if possible. Where notpossible, position machine at a right angle to the slope,making sure there is no danger of uncontrolled slidingmovements.

- If parking in traffic lanes cannot be avoided, provideappropriate flags, barriers, flares and signals as re-quired. Also provide advance warning signals in thetraffic lane of approaching traffic.

- Keep head, body, limbs, feet, fingers or hands away frombucket, blade or ripper when in raised position.

- Always disconnect the master switch before any inter-vention (i.e. cleaning, repairing, maintaining, refuelling

XSAFETY RULES

SAFETY RULES FOR SEALS

VITON SEALS (FLUOROELASTOMER)

Seals, especially VITON O-Rings, (normally coloured red)are used in systems operating at high temperatures, sincethis materials resists the effects of heat. However, in theevent this material is subject to heat exceeding 315 C (599F) (in practice, only in case of fire or when using weldingflames) fluoridic acid is generated. This acid is highlycorrosive and could cause severe burns, if in contactwith the skin.Every time it is necessary to intervene on componentsequipped with VITON rings, for which an exposure toexcessive temperatures is suspected, the following proce-dures must be applied:

1) inspect visually, without touching them, all seals show-ing signs of damage due to high temperature. They look

black and tacky;2) identify the type of material of the seals, if they are

VITON, performing the test illustrated below, on thespare parts;

3) in case it is verified, or there is a reasonable doubt thatthe components are made of VITON, the contaminatedarea MUST be decontaminated before proceeding withfurther operations;

4) wear neoprene rubber or PVC gloves and protectiongoggles or face screen, and wash accurately the con-taminated zone with a solution of hydraulic lime (foundat building stores) and water, so that a milky liquid isobtained. Rinse carefully with steam or running water;

5) dispose of the materials removed and the protectivegloves in a safe manner, without burning them.

The machine uses a differential steering system; this consists of a hydraulic pump, a hydraulicmotor, controls, two planetary modules and a steering gear train.The rear transmission has two power inlets. One from the bevel gear for the speed andForward reverse, the other from the motor, to turn.The steering system is actuated by two "finger tip" potentiometric levers, located on the leftside of the operator's seat.

The levers send an electric signal to the microprocessor controlling the two proportionalsolenoid valves; these valves convert the electric signal into a hydraulic one, piloting thesteering section of the main valve.This section controls the pump flow to the hydraulic motor that through the steering gear train,actuates the two planetary modules and the right track chain.

GENERAL INSTRUCTIONS

INSTALLATION OF SEALSFOR ROTATING SHAFTSOsservate le seguenti avvertenze:- prior to installation, keep the seals half an hour

dipped into the same oil they are going to seal;

- clean accurately the shaft and make sure that itsworking surface is undamaged;

- direct the sealing lip towards the fluid; in case of anhydro dynamic lip, the grooves must be orientedso that the rotating direction of the shaft, tend toreturn the oil inside the seal;

- smear the sealing lip with a film of lubricant (oil ispreferred to grease);

- install the seal into its seat by pressing it or using apunch with a flat contact face; absolutely avoidhammering it;

- when pressing the seal, make sure that it is enteredperpendicularly to its seat and once the pressing isover, make sure, when requested, that is seatedagainst the shoulder;

- in order to avoid damaging the sealing seat withthe shaft, it is recommended, during the installationof the two parts, to insert an appropriate seal.

INSTALLATION OF O-RINGSLubricate the seals before placing them into therelevant seats so as to avoid that, during theinstallation, they tend to roll, thus altering their correctpositioning, being furled, causing prejudice to theirsealing function.

RECOMMENDATIONS FOR THE DISASSEMBLYAND REASSEMBLY OF GROUPSThe following information, of a general nature, areintended to facilitate the disassembly and reassemblyof groups.Consequently, read and heed them when performingthis type of operations.

CLEANINGAfter disconnecting the electrical system, cleanaccurately all the parts to be disassembled, preferablyusing steam.In many repair or service workshops, causticcompounds are used to eliminate all traces of grease,dirt, paint or remains of sealing materials etc. fromthe parts. These compounds are very useful andefficient when used correctly; however they can causeconsiderable damages to certain components.Materials such as aluminium, rubber, fibres, sinteredbronze and alloying elements are particularly sensitiveto all highly concentrated caustic compounds.Some heat exchangers are made with aluminium fins.To clean internally or outside these parts, the use ofsolvents not reacting with aluminium arerecommended.

DISASSEMBLYIt is always recommended, for any intervention onengines or other assemblies removed form themachine, that appropriate stands are used.Make available baskets or containers sufficient tostore all the smaller size parts disassembled. Takeparticular care of machined faces of the components,placing them, after the disassembly, on shelves orwooden blocks.When identical parts are disassembled, such asvalves, tappets etc., place them in appropriatecontainers to ensure the same mating order whenreassembling.

ASSEMBLYClean accurately all the components to bereassembled, as described by the various chaptersof the Manual.The use of the proper special tools shown in the Manualis recommended.

Note When applying sealing adhesive compounds,comply with the instructions provided with commercialproducts.

0 - 23D350


GENERALITIES

The manufacturer prescribes, unless differentlyspecified, the following adhesive compounds:RHODORSIL CAF 1, or LOCTITE 510.Whenever possible, press bushes into their correctposition using a press.In the event it is necessary to use a hammer to installa bush, use an appropriate punch to avoid damagingthe bush.Lubricate ball bearings prior to their installation. Lubri-cate the sealing lip of all seals, prior to their installa-tion.Whenever possible, install new seals; in particular newgaskets must be used on engine cylinder heads.Use screws with the dimensions and grade indicated,referring to the part number of the Spare Parts Cata-logue.When indicated, safety washers, split pins and lock-ing wires etc. must be used.Comply with the prescribed tightening torques indi-cated in the "Tightening torques" section of thisManual, using an appropriate torque wrench.Self-locking nuts must be replaced at each disassem-bly, to ensure a constant good performance againstloosening.

HIGH PRESSURE PIPES, CONNECTIONS,HOSES AND PIPESThis chapter provides correct recommendations andprocedures to be followed during the disassembly ofpipes and relevant connections.

- Keep all internal and external threads clean;

- Remove the plugs just before connecting the pipesand plug at once all open connections.

- Do not use or reuse semi flanges out of shape morethan 0.6 mm (0.02 in) in the centre (see figure).

- Make sure that the seats of O-rings are undamaged.

- Lubricate all O-Rings.

- Make sure that O-Rings are in place in the relevantseat.

- Tighten regularly so as to avoid distortions or dam-ages to O-Rings;

GENERALITIES

- Install pipes and support bands letting the latterslightly loosen (tighten the band only after tighten-ing the connections).

- Make sure that the hoses reach the correspondingpart to be connected to without forcing their posi-tion.

- In the event a hose is mounted straight, let enoughspace to absorb contractions caused by pressure.

- Hoses must not be rolled (see figure) or touchingone another or touching other parts, especially ifmoving.

- Make sure that the dimension of the bands isappropriate for the outer diameter of the pipe to betighten to avoid possible rubbings (see figure).

- Do not install bands on small diameter curves, toavoid that, under pressure, forces are generated inthe pipe (see figure: the dotted lines indicate thecontraction that the hose could be subject to underthe action of the pressure).

- Make sure that bands are installed in a correct po-sition so that the hose is kept away from obstacles(see figure).

GENERALITIES

GENERALITIESFor a fast troubleshooting, we recommend the com-pliance with the following rules:

a) Knowing the machineIt is impossible to research the causes and formulate a diagnosis of troubles without having a good knowl-edge of the machine. Thus it is recommendedthat the descriptions regarding the arrangement andthe operation of the various groups provided by theRepair Manuals are carefully read.

b) Inspection with the operatorMany trouble originate from a bad use or insufficientmaintenance. Check with the operator if the machinewas previously subject to the current trouble and even-tual interventions have been performed with appropri-ate equipment and genuine spare parts. Also,check the environmental working conditions of themachine and make sure that current maintenance isperformed.

c) Operating the machineThe best way to ascertain the conditions of themachine is to test it under real working conditions.During such test, check:

- the correct operation of the monitoring instrumen-tation;

- the performance of the machine;

- eventual odours or signs of overheating;

- noises different from normal operation noises; iden-tify their origin and the operating conditions duringwhich they occur.

d) Inspection of the machineAfter the test described in item c, stop the machineand perform a visual inspection. Check whether leak-ages of fluids, loosening of fixtures, breakages orvarious deformations etc. occurred.

e) DiagnosisOnce the trouble is identified. prepare a list of thepossible causes with the help of the suggestions ofthe chapter for the group involved and identify thecorrect one, using practical tests, starting from themost probable causes and the easiest tests.
