never check or fill fuel reservoirs or batteries near open
flames, smoking materials or sparks.
- REMEMBER THAT STARTING FLUID IS FLAMMABLE.
Follow strictly the recommendations printed on contain-
ers and in the Operation and Maintenance Manual.
- DO NOT PUNCTURE OR BURN CONTAINERS.
- Containers must be stored in fresh, well ventilated plac-
es, out of reach of unauthorised persons. Follow strictly
the instructions provided by the Manufacturer.
- Never use these products near open flames, smoking
materials or sparks.
OPERATION
- Do not run the engine of this machine in closed areas
without proper ventilation to remove deadly exhaust
gases.
- Roll Over Protective Structures are required on loaders,
dozers, graders, excavators.
WARNING
- Do not allow unauthorised personnel to operate service
or maintain this machine.
- Do not wear rings, wrist watches, jewellery, loose or
hanging apparels, such as ties, torn clothing, scarves,
unbuttoned or unzipped jackets that can catch on mov-
ing parts. Wear proper safety equipment as recom-
mended for the job. Examples: hard hat, heavy gloves,
ear protection, safety glasses or goggles, reflector vests,
respirator. Consult your employer for specific safety
equipment requirements.
- Keep operator's compartment, stepping points, grab-
rails and handles clear of foreign objects, oil, grease,
mud or snow accumulation to minimise the danger of
slipping or stumbling. Clean mud or grease from shoes
before attempting to mount or operate the machine.
- Do not jump on or off the machine. Keep two hands and
one foot, or two feet and one hand in contact with step
grab rails and handles at all times.

CHINE.

SAFETY RULES
Keep cab windows clean and repaired.
- When machines are operating in tandem, the pusher (rear)
must be equipped with the appropriate deflectors to protect
theunitinfrontfromtheairstreamcomingfromtheradiator.
- When pulling or towing through a cable or chain, do not
start 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 a
kinked chain or cable to the high stresses and possibility
of failure of the kinked area. Always wear heavy gloves
when handling chains or cables.
- Be sure chains and cables are anchored and the anchor
points are strong enough to handle the expected load.
Keep exposed personnel clear of anchor points and
cables or chains.

- Be alert to soft ground conditions close to newly construct-
ed walls. The fill material and weight of the machine may
cause the wall collapse under the machine.
- In darkness, check area of operation carefully before
moving in with machine. Use all lights provided. Do not
move into area of restricted visibility.
- If engine has a tendency to stall for any reason under load
or idle, report this for adjustment to proper maintenance
authority immediately. Do not continue to operate ma-
chine, until condition has been corrected.
- On machines supplied with suction radiator fans, be sure
to periodically check engine exhaust parts for leaks, as
exhaust fumes are dangerous to the operator.
- In case of closed type cabs, always keep an opening with
the outside, to ensure a constant air circulation.
- Operators must know thoroughly the performances of the
machine they are operating. When working on slopes or
near sudden level drops of the terrain, avoid areas where
ground is loose or soft since rolling-over or loss of control
of machine could result.
- Where noise exposure exceeds 90 dBA for 8 hours, wear
approved ear protection.
- When counterweights are provided, do not work machine
if they have been removed.
NEVER OPERATE machines without ROPS.
- Make sure the Operator's compartment is free of foreign
objects, especially if not firmly secured. Never use the
machine to transport objects, unless proper securing
points are provided.
- Check monitoring instruments at start-up and frequently
during operations. in case the brake pressure gauge
shows a pressure lower than the minimum operating
pressure, stop immediately the machine .
- DO NOT CARRY RIDERS ON MACHINE
- Study and familiarise with escape routes alternate to
normal exit routes.
- Seat belts are required by current regulations to be provid-
ed with Roll Over Protection Structures or cabs. Keep
safety belts fastened around you during operation.
- For your personal protection, do not climb on or off
machine while machine is in motion.
- Make sure that exposed persons in the area of operation
are clear of the machine, before starting the engine and
operatingtheequipment.Soundhorn.Obeyallindications
provided by flags and signals.
- NEVER COAST the machine down grades and slopes
with the transmission in neutral or neutralised.

the speed required, thus preventing any loss of control.
- Donotoperatemachineryinaconditionofextremefatigueor
illness.Beespeciallycarefultowardstheendofworkingshift.
- 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 to be
moved. Be alert to the position of exposed personnel. DO
NOTOPERATEifexposedpersonnelentertheimmediate
work area. STOP THE MACHINE.
- Maintain a safe distance from other machines. Provide
sufficient clearance for ground and visibility conditions.
Yield right-of-way to loaded machines.
- Maintain clear vision of areas of travel or work.
II

SAFETY RULES
- Overtaking manoeuvres must be performed only when
absolutely necessary and unavoidable. Beware of possi-
ble 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 working
conditions in the site and slow enough to ensure complete
control at all times.
- Never use the machine as a work platform or scaffolding,
nor other inappropriate operations (i.e. pushing railway
cars, trucks or other machines).
- Be alert of people in the operating area of the machine.
- When operating a machine, know in advance what clear-
anceswillbeencountered,overheaddoors,cables,pipes,
bearing load limitations of ground, bridges, floors or
ramps.
- When roading, find-out what conditions are likely to be
encountered, clearances, traffic congestion, type of road
surfacing, etc. Beware of fog, smoke or dust elements that
obscure visibility.
- When crossing gullies or ditches, move at an angle with
reduced speed after ensuring ground conditions will per-
mit a safe traverse.
- Exploretheworkingareatoidentifypotentialriskssuchas:
slopes, overhangs, pits, demolition rubble, fires, ravines,
ditches, soft terrain, heavy traffic, crowded parking areas,
closed ambients. In such conditions, proceed with ex-
treme care.
- Whenever possible, avoid going over obstacles such as
rough terrain, rocks, logs highly irregular ground, steps,
ditches, railroad tracks. When obstructions must be
crossed, do so with extreme care at an angle, if possible.
Reduce speed, shift-down. Ease up to the break over
point, pass the balance point slowly on the obstruction and
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 and
down the slope. Should the machine slipping sideways,
turn it immediately downhill.
- The grade of slope you should attempt will be limited by
factors such as condition of the ground, load being han-
dled, type of machine, speed of machine and visibility.
- There is no substitute for good judgement when working
on slopes.
- Avoid operating equipment too close to an overhang or
high wall, either above or below the machine. Be on the
look-out for caving edges, falling objects and slides.
Beware of concealment by brush and undergrowth of
these danger.
- When pushing-over trees, the machine must be equipped
with proper overhead guarding. Never allow a machine to
climb up on the root structure particularly while the tree is
being felled. Use extreme care when pushing over any
tree with dead branches.
- When pushing trees with dead limbs, proceed with ex-
treme care. Avoid brush piles, logs or rocks.
- NEVER DRIVE OVER THEM or other surface irregulari-
tiesthatbraketractionwiththeground,especiallywhenon
slopes or near drop-offs.
- Be alert to avoid changes in traction conditions that could
cause loss of control. DO NOT DRIVE on ice or frozen
ground conditions when working the machine on steep
slopes or near drop-offs.
- Working in virgin and rough terrains is characterised by
the presence of all the perils and risks listed above. In
these conditions, it is emphasised the danger represented
by large tree limbs (possibly falling on the machine), large
roots (acting as a leverage under the machine when up-
rooted causing the roll-over of the unit) etc..
STOPPING
- When the machine is stopped for whatever reason, follow
the instructions of chapters "Stopping the machine" and
"Stoppingtheengine"oftheOperationandMaintenance
Instruction Manual.
- Always remember to position the transmission drive control
inneutralandengagethecontrollocktosecurethemachine.
- The parking brake is automatically set, when the transmis-
sion safety lever is lowered.
- NEVER LEAVE THE MACHINE UNATTENDED with the
engine running.
- Always, before leaving the operator's seat and after mak-
ing sure all people are clear of the machine, slowly lower
the attachments or tools flat to the ground in a positive
ground support position.
III

SAFETY RULES
- Return the controls to rest position. Place the gearshift
lever in neutral. Disconnect the master switch and extract
the key.
- Park in a non- operating and no-traffic area or as instruct-
ed. Park on firm level ground if possible. Where not
possible, position machine at a right angle to the slope,
making sure there is no danger of uncontrolled sliding
movements.
- If parking in traffic lanes cannot be avoided, provide
appropriate flags, barriers, flares and signals as re-
quired. Also provide advance warning signals in the
traffic lane of approaching traffic.
- Keep head, body, limbs, feet, fingers or hands away from
bucket, blade or ripper when in raised position.
- Always disconnect the master switch before any inter-
vention (i.e. cleaning, repairing, maintaining, refuelling
etc.). Do the same when parking for prolonged periods
of time to avoid accidental or unauthorised starting.
- Never lower attachments or tools other than seated in
operator's seat. Sound horn. Make sure area near the
attachment is clear. Lower the attachment slowly. DO
NOT USE FLOAT POSITION of hydraulic system.

SAFETY RULES
WARNING
On machines having hydraulically, mechanically, and/or cable controlled equipment (such as shovels,
loaders, dozers, excavators etc.) be certain the equipment is lowered to the ground before servicing,
adjusting and/or repairing. If it is necessary to have the hydraulically, mechanically, and/or cable con-
trolled equipment partially or fully raised to gain access to certain items, be sure the equipment is
suitably supported by means other than the hydraulic lift cylinders, cable and/or mechanical devices
used for controlling the equipment.
VII
ELECTRICAL SYSTEM
- Disconnect batteries prior to any intervention on ma-
chine or electrical system (cleaning, repair, mainte-
nance).
- Should booster batteries be used, remember to connect
both ends of the booster cables in the proper manner (+)
with (+) and (-) with (-). Avoid short-circuits of the termi-
nals. Follow thoroughly the instructions of this Manual.
- Before any intervention, make sure that the main switch is
OFF.
- BATTERY GAS IS HIGHLY FLAMMABLE. Leave bat-
tery box open to improve ventilation when recharging
batteries. Never check charge by placing metal objects
across the posts. Keep sparks or open flames away from
batteries. Do not smoke near battery to guard against the
possibility of causing an explosion.
- Before any intervention, make sure that there are no fuel
or electrolyte leakages; eliminate them before proceed-
ing with further work. When recharging batteries in
closed ambients, make sure that there is appropriate
ventilation to prevent possible accidental explosions due
to the accumulation of gases generated during the
recharge.
HYDRAULIC SYSTEM
- Fluid escaping under pressure from a very small hole
can be almost invisible and can have sufficient force to
penetrate the skin. Use a piece of cardboard or wood to
search for suspected pressure leaks. DO NOT USE
HANDS. If injured by escaping fluid, see a doctor at
once. Serious infection or reaction can develop if proper
medical treatment is not administered immediately.
- Stop the engine and release all pressures in the system
before removing panels, housings, plugs or covers.
- In case pressures must be measured, use instruments of
adequate capacity. Always follow the recommended
procedures.
TOOLS
- Keep head, body, limbs, feet, fingers or hands away from
bucket, blade or ripper when in raised position.
Prior to any intervention, install all safety devices accord-
ing to current rules and regulations.
- In case equipment on the machine must be operated
by hydraulic systems, remember to proceed only
after seating in the operator's compartment. Make
sure that there are no persons in the operating area
of the machine. Alert people before operating using
the horn and by voice. Move the equipment very
carefully.
- Do not use machine to transport loose objects, unless
proper devices for this purpose are provided.
- Clutches and brakes of this machine and eventual aux-
iliary equipment and attachments (such as operating
cylinder or winches control valves) must always be
properly adjusted in accordance with the instructions
provided by the Manuals of the Manufacturer.
- Never perform adjustments with engine running, except
when called for by the above instructions.
When changing work shift, check that wheel or rim
securing screws and brackets are not loosen; if neces-
sary, retighten to the prescribed torque.

SAFETY RULES
SAFETY RULES FOR SEALS
VITON SEALS (fluoroelastomer)
Seals, especially VITON O-Rings, (normally coloured red)
are used in systems operating at high temperatures, since
this materials resists the effects of heat. However, in the
event this material is subject to heat exceeding 315 °C (599
°F) (in practice, only in case of fire or when using welding
flames) fluoridic acid is generated. This acid is highly
corrosive and could cause severe burns, if in contact
with the skin.
Every time it is necessary to intervene on components
equipped with VITON rings, for which an exposure to
excessive 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 the
spare parts;
3) in case it is verified, or there is a reasonable doubt that
the components are made of VITON, the contaminated
area MUST be decontaminated before proceeding with
further operations;
4) wear neoprene rubber or PVC gloves and protection
goggles or face screen, and wash accurately the con-
taminated zone with a solution of hydraulic lime (found
at building stores) and water, so that a milky liquid is

The machine uses a differential steering system; this consists of a hydraulic pump, a hydraulic
motor, controls, two planetary modules and a steering gear train.
The rear transmission has two power inlets. One from the bevel gear for the speed and Forward
reverse, the other from the motor, to turn.
The steering system is actuated by two "finger tip" (potentiometric levers), located on the left side
of the operator's seat.
The levers send an electric signal to the microprocessor controlling the two proportional solenoid
valves; these valves convert the electric signal into a hydraulic one, piloting the steering 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.
The open hydrostatic circuit includes:
- main pump

STEERING
SYSTEM
D180
The steering system is driven by two levers located on the left side of the
operator's compartment. During translation, the lever sends a modulated
pressure through the electronic control unit and the electroproportional valves
to the steering control valve. The first pressure controls the steering clutch
disconnection. The second pressure is equal to zero until the first pressure
reaches 16 bar (50% of lever stroke). It applies the steering brakes positively.
The service brake system is negatively controlled by the brake pedal or by
pulling the two levers at the same time. The pedal operation cuts the brake
system counterpressure with modulation and applies the braking load with
the springs.

GENERAL INSTRUCTIONS
INSTALLATIONOFSEALSFORROTATINGSHAFTS
Please comply with the following advises:
- 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 its
working surface is undamaged;
- direct the sealing lip towards the fluid; in case of an
hydro dynamic lip, the grooves must be oriented
so that the rotating direction of the shaft, tend to
return the oil inside the seal;
- smear the sealing lip with a film of lubricant (oil is
preferred to grease);
- install the seal into its seat by pressing it or using a
punch with a flat contact face; absolutely avoid
hammering it;
- when pressing the seal, make sure that it is en-
tered perpendicularly to its seat and once the press-
ing is over, make sure, when requested, that is
seated against the shoulder;
- in order to avoid damaging the sealing seat with
the shaft, it is recommended, during the installa-
tion of the two parts, to insert an appropriate seal.
INSTALLATION OF O-RINGS
Lubricate the seals before placing them into the rel-
evant seats so as to avoid that, during the installa-
tion, they tend to roll, thus altering their correct posi-
tioning, being furled, causing prejudice to their seal-
ing function.
Re-install the elastic rings as follows:
- Press the ring so as to have one end and part of
the inner circumference touching the bottom of the
relevant seat (b);
REMOVALANDINSTALLATIONOFELASTICRINGS
FORROTATINGSEALING
Remove the rings as follows:
- press the ring so that one end and part of the inner
circumference contact the bottom of the relevant
seat (a);
- keep the ring in the position above and, acting with
a scriber on the other end, free the catches, as
indicated in the figure (a).

RECOMMENDATIONSFORTHEDISASSEMBLYAND
REASSEMBLYOFGROUPS
The following information, of a general nature, are
intended to facilitate the disassembly and reassembly
of groups.
Consequently, read and heed them when performing
this type of operations.
CLEANING
After disconnecting the electrical system, clean ac-
curately all the parts to be disassembled, preferably
using steam.
In many repair or service workshops, caustic com-
pounds are used to eliminate all traces of grease,
dirt, paint or remains of sealing materials etc. from
the parts. These compounds are very useful and ef-
ficient when used correctly; however they can cause
considerable damages to certain components.
Materials such as aluminium, rubber, fibres, sintered
bronze and alloying elements are particularly sensi-
tive to all highly concentrated caustic compounds.
Some heat exchangers are made with aluminium fins.
To clean internally or outside these parts, the use of
solvents not reacting with aluminium are recom-
mended.
DISASSEMBLY
It is always recommended, for any intervention on
engines or other assemblies removed form the ma-
chine, that appropriate stands are used.
Make available baskets or containers sufficient to
store all the smaller size parts disassembled. Take
particular care of machined faces of the components,
placing them, after the disassembly, on shelves or
wooden blocks.
When identical parts are disassembled, such as
valves, tappets etc., place them in appropriate con-
tainers to ensure the same mating order when reas-
sembling.
ASSEMBLY
Clean accurately all the components to be reassem-
bled, as described by the various chapters of the
Manual.
The use of the proper special tools shown in the
Manual is recommended.
Note – When applying sealing adhesive compounds,
comply with the instructions provided with commer-
cial products.
- install the ring in the position describe above and
lift the free end (b) moving it until the two catches
engage correctly (c).

0 - 32 D180
Wrong Correct
The manufacturer, prescribes, unless differently
specified, the following adhesive compounds:
RHODOSIL CAF 1, or LOCTITE 510.
Whenever possible, press bushes into their correct
position using a press.
In the event it is necessary to use a hammer to install
a bush, use an appropriate punch to avoid damaging
the bush.
Lubricate ball bearings prior to their installation. Lu-
bricate the sealing lip of all seals, prior to their instal-
lation.
Whenever possible, install new seals; in particular
new gaskets 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 this
Manual, using an appropriate torque wrench.
Self-locking nuts must be replaced at each disassem-
bly, to ensure a constant good performance against
loosening.
HIGH PRESSURE PIPES, CONNECTIONS, HOSES
AND PIPES
This chapter provides correct recommendations and
procedures to be followed during the disassembly of
pipes and relevant connections.
- Keep all internal and external threads clean;
- Remove the plugs just before connecting the pipes
and plug at once all open connections.
- Do not use or reuse semi flanges out of shape more
than 0.6 mm in the centre (see figure).
- Make sure that the seats of O-rings are undam-
aged.
- Lubricate all O-Rings.
- Make sure that O-Rings are in place in the relevant
seat.
- Tighten regularly so as to avoid distortions or dam-
ages to O-Rings.
- Install pipes and support bands letting the latter
slightly loosen (tighten the band only after tighten-
ing the connections).
- Make sure that the hoses reach the corresponding
part to be connected to without forcing their posi-
tion.
- In the event a hose is mounted straight, let enough
space to absorb contractions caused by pressure.
- Hoses must not be rolled (see figure) or touching
one another or touching other parts, especially if
moving.

0 - 33D180
- Make sure that the dimension of the bands is
appropriate for the outer diameter of the pipe to be
tighten to avoid possible rubbings (see figure).
- Do not install bands on small diameter curves, to
avoid that, under pressure, forces are generated in
the pipe (see figure: the dotted lines indicate the
contraction that the hose could be subject to under
the action of the pressure).

GENERALITIES
For a fast troubleshooting, we recommend the com-
pliance with the following rules:
a) Knowing the machine.
It is impossible to research the causes and formula
te a diagnosis of troubles without having a good knowl-
edge of the machine. Thus it is recommended
that the descriptions regarding the arrangement and
the operation of the various groups provided by the
Repair Manuals are carefully read.
b) Inspection with the operator
Many trouble originate from a bad use or insufficient
maintenance. Check with the operator if the machine
was previously subject to the current trouble and
eventual interventions have been performed with
appropriate equipment and genuine spare parts.Also,
check the environmental working conditions of the
machine and make sure that current maintenance is
performed.
c) Operating the machine
The best way to ascertain the conditions of the
machine 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 during
which they occur.
d) Inspection of the machine
After the test of item c, stop the machine and have a
visual inspection. Check whether the various groups
show leakages of fluids, loosen bolts, failures of de-
formations etc.
e) Diagnosis
Once the trouble is identified. prepare a list of the
possible causes with the help of the suggestions of
the chapter for the group involved and identify the
correct one, using practical tests, starting from the
most probable causes and the easiest tests.
