WARNING
On machines having hydraulically, mechanically
and/or cable controlled equipment (such as
showels, loaders, dozers, scrapers etc.) be certain
the equipment is lowered to the ground before
servicing, adjusting and/or repairing.
If it is necessary to have the 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 device used for controlling the equip-
ment.
Mostaccidentsandinjuriesoccurringinindustry,onthe
farm, at home or on the road, are caused by the failure
of some individual to follow simple and fundamental
safety rules or precautions. For this reason, MOST
ACCIDENTS CAN BE PREVENTED by recognizing
the real cause and taking the necessary precautions,
before the accident occurs.
Regardlessofthecareusedindesignandconstruction
of any type of equipment, there may be conditions that
cannot be completely safeguarded against without in-
terfering with reasonable accessibility and efficient op-
eration.
A careful operator is the best insurance against acci-
dents. The complete observance of one simple rule
would prevent many thousands serious injuries each
year.
This rule is: Never attempt to clean, lubricate or adjust
a machine while it is in motion.

GENERALITIES
Carefully read personal and machine SAFETY PRECAUTIONS (at the beginning of this manual)
0 - 3W170/W170TC
Always inspect the working area to identify potential risks
such as: inclines, overhangs, trees, demolition rubble,
fires,ravines,steep slopes, roughterrain,ditches,crowns,
ridge trenches, heavy traffic, crowded parking and service
areas, closed ambients. In such conditions, proceed with
extreme care.
Whenever possible, avoid going over obstacles such as
very rough terrain, rocks, logs, steps, ditches, railroad
tracks. When obstructions must be crossed, do so with
extreme care and at an angle, if possible. Slow down and
select a lower gear. Ease up to the break-over point, pass
the balance point slowly and ease down the other side.
In steep down-hill operation, do not allow the engine to
over-speed. Select the proper gear before starting down
grade.
Avoid crosswise hill travel, whenever possible. Drive up
and down the slope. Should the machine start slipping
sideways when going uphill, steer and turn machine front
immediately downhill.
The gradient you may attempt to overcome is limited by
factors such as ground conditions, load being handled,
machine type and speed, and visibility.
There is no substitute for good judgement and experience
when working on slopes.
Avoid operating the attachment too close to an overhang
or high wall, either above or below the machine. Beware
of caving edges, falling objects and landslips. Remember
that such hazards are likely to be concealed by bushes,
undergrowth and such.
When pushing-over trees, the machine must be equipped
with proper overhead guards. Never drive a machine up
the roots, particularly while the tree is being felled. Use
extreme care when pushing over any tree with dead
branches.
Avoid faggots, bushes, logs and rocks.
NEVER DRIVE OVER THEM, nor over any other surface
irregularities that discontinue adherence or traction with
the ground, especially near slopes or drop-offs.
Be alert to avoid changes in traction conditions that could
cause loss of control. AVOID driving on ice or frozen
ground when working on steep slopes or near drop-offs.
Working in virgin rough terrains is characterized 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 (which may act as a leverage under the machine
when up-rooted and cause the unit to overturn), etc.
STOPPING
When the machine is to be stopped for whatever reason,
do so following the instructions given in chapters “Stop-
ping the machine” and “Shutting off the engine" in the
Operation and Maintenance Instruction Manual.
Alwaysremembertomovethegearshiftlevertothe neutral
position and engage the control lever lock for safety
purposes.
Apply the parking brake (if fitted).
NEVER LEAVE THE MACHINE UNATTENDED with the
engine running.
Prior to leaving the operator’s seat,and after making sure
that all people are clear of the machine, always slowly
lower the attachment until resting it safely to the ground
Park the machine in a non-operating and no-traffic area.
Parkonfirmlevelground.Ifthisisnotpossible,positionthe

If parking in traffic lanes cannot be avoided, provide
appropriate flags, barriers, flares and signals as required
to adequately warn the oncoming drivers.
Keephead, body, limbs, hands and feet clear of the dozer,
arms, bucket or ripper when raised.
Always switch off the battery isolator switch before serv-
icing the machine in whatever manner (i.e., cleaning,
repairing, maintaining, etc.). Do the same when the
machine is to remain parked for prolonged periods of time
to avoid accidental or unauthorized starting.
Never lower the attachments other than sitting in the
operator’s seat. Sound the horn. Make sure that nobody is
withinthemachineoperating range. Lower the attachment

turer. Never perform adjustments with the engine running,
except when this is specifically required by the relevant
procedures.
TYRES AND WHEELS
Make sure that the tyre inflation pressure corresponds to
specifications issued by the Manufacturer. Regularly
check inflation pressure.
Should pressure be changed, do this while staying on the
tyre side and at a safe distance.
Pressure checks should always be carried out with the
machine unloaded and cold tyres.
Never use reconditioned tyre rims, since possible
weldings, incorrect heat-treatments or repairs can
weaken the wheels and cause damages or failures.
Do not cut, nor weld rims with inflated tyres installed.
The spare tyre should be inflated only enough to keep the
rim components assembled. Remember that when not
installed on the disc, a tyre inflated to maximum pressure
can explode.
Therefore, maximum care must be taken when handling a
fully inflated tyre.

• The decommissioning of the machine must be
performed exclusively by personnel trained,
qualified and authorised to perform such op-
eration.
• Startthedisassembly of hydrauliccomponents
only after the same, the hydraulic oil and lubri-
cantshave fully cooled-offand afterall residual
pressureshave been released, as described by
the Repair Instruction Manual.
• Prior to proceeding with disassembly opera-
tions, comply with the GENERAL SAFETY
RULES and drain each components of the ma-
chine filled with fluids, both in the reservoirs
and the relevant systems.
WARNING
Ensure that the attachment is safely resting on to the ground before repairing,adjusting, or servicing
machines fitted with hydraulically, mechanically or cable controlled attachments (such as excavators,
loaders, dozers, scrapers, etc.). Should it be necessary to partially or fully raise the hydraulically, me-
chanically, or cable controlled attachment to gain access to certain items, make sure the attachment is
adequately retained in the raised position by means other than the hydraulic lift cylinders, cable and/or
mechanical devices used for controlling it.
