and the materials to be handled. Follow the
recommendations concerning loading capacity,
arrangementofthematerials,characteristicsoftheground
and job to be performed.
Do not lift and move loads overhead where any personnel
are standing or working, nor downhill when working
crosswise on slopes. In this case, the bucket should be
unloaded on the uphill side, whenever possible.
Startandstopthemachinecarefullywhenthebucketisfull.
Do not move off without first reducing engine speed.
Overtaking maneuvres should be performed only when
absolutely necessary and unavoidable. Beware possible
uneven terrains, poor visibility, presence of other
machinery or personnel out of sight.
Operate the machine at a speed adequate to the working
site conditions and in any case slow enough to ensure
complete control at all times.
Check instruments at start-up and frequently during
operation. Stop the machine immediately should any
malfunction be signalled.

or problems you will encounter, such as narrow streets,
overheaddoors,cables,piping,aswellasground,bridges,
paving and ramps bearing load limitations.
In case of road transfers, find out beforehand what
conditions are likely to be encountered, such as size
restrictions, heavy traffic, paving type, etc. . Beware fog,
smoke or dust that obscure visibility.
When crossing gullies or ditches, move at an angle with
reduced speed after ensuring ground conditions will

MAINTENANCE
GENERALITIES
Before operating or performing any intervention on the
machine:
- carefully read all the norms contained in this Manual;
- read and observe all safety plates and instructions
located on the machine.
Do not allow unauthorized personnel to service the
machine. Do not carry out any maintenance work without
prior authorization. Follow all recommended maintenance
and service procedures.
Keeptheoperator’scompartmentfreeof looseobjectsthat
are not properly secured.
Do not wear rings, wrist watches, jewellery, loose or
hanging garments, such as ties, torn clothing, scarves,
such as: inclines, overhangs, trees, demolition rubble,
fires,ravines, steepslopes,roughterrain,ditches,crowns,
ridge trenches, heavy traffic, crowded parking and service
areas, closed ambients. In such conditions, proceed with
extreme care.
When ever 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
orhighwall,eitheraboveorbelowthemachine.Beware of
caving edges, falling objects and landslips. Remember
that such hazards are likely to be concealed by bushes,
undergrowth and such.
Whenpushing-trees over,themachinemustbeequipped
withproperoverheadguards.Neverdriveamachineup the
roots,particularlywhilethetreeisbeingfelled.Useextreme
care when pushing any tree over with dead branches.
Avoid bushes, logs and rocks.
NEVER DRIVE OVER THEM, or 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 emphasized 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
“Stopping the machine” and “Shutting off the engine"
in the Operation and Maintenance Instruction Manual.

Carefully read personal and machine SAFETY PRECAUTIONS (at the beginning of this manual)

Ensure proper ventilation is provided to avoid accidental
explosions due to build-up of gas released during charg-
ing.
HYDRAULIC SYSTEM
Pressure fluid escaping from a very small hole can be
almost invisible and still have sufficient force to penetrate
the skin. Always check any suspected pressure leaks
using a piece of cardboard or wood. DO NOT USE
HANDS. If injured by escaping fluid, obtain medical
attention immediately or serious infection or reaction may
develop.
Stop the engine and relieve all system pressure before
removing panels, housings, caps, plugs or covers.
Always use gauges of adequate capacity (end-of-scale
reading) and follow recommended procedures.
TOOLS
Always keep head, body, limbs, feet, or hands away from
bucket, blade, or ripper when in the raised position. Prior
to any intervention, install all safety devices according to
current regulations. In case the attachment is to be oper-
ated through the machine hydraulic system for mainte-
nancepurposes,remembertodosoonlywhilesittinginthe
driver's seat. Make sure that no personnel is within the
machine operating range. Before operating the
attachment, alert personnel by sounding the horn and by
voice. Raise the attachment slowly.
Do not use the machine to transport loose objects, unless
proper devices to this purpose are provided.
Clutches and brakes of this machine as well as auxiliary
devices and attachments (such as drive cylinder or winch
control valves) should always be properly adjusted in
accordance with the instructions provided by the Manu-
facturer. Never perform adjustments with the engine
running, except when this is specifically required by the
relevant procedures.
TIRES AND WHEELS
Make sure that the tire inflation pressure corresponds to
specifications issued by the Manufacturer. Regularly
check inflation pressure.
Should pressure be changed, do this while staying on the
tire side and at a safe distance.
Pressure checks should always be carried out with the
machine unloaded and cold tires.
Neverusereconditionedtirerims,sincepossibleweldings,
incorrect heat-treatments or repairs can weaken the
wheels and cause damages or failures.
Do not cut, nor weld rims with inflated tires installed.
The spare tire should be inflated only enough to keep the
rim components assembled. Remember that when not
installed on the disc, a tire inflated to maximum pressure
can explode.
Therefore, maximum care must be taken when handling a
fully inflated tire.

loaders, dozers, scrapers, etc.). Should it be necessary to partially or fully raise the hydraulically,
mechanically, 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.
WARNING
SAFETY RULES
For the decommissioning of the machine, the
availability of particular tooling (hoists, hydraulic
presses. containers for liquids etc.) is required as
well as specific tools listed in the Repair Manuals,
available from NEW HOLLAND CONSTRUCTION
Dealers.
This has the purpose of avoiding that during
disassembly operations, dangerous situations may
arise both for the personnel involved and the
environment.
In the machine are present:
•Fluids under pressure (hydraulic system, cooling
system etc.)
•Gases (air conditioning system and accumulator, if
installed)
•Mechanical devices mounted under pressure
(track tensioner etc.)
•Heavy machine components (frames, blades,
buckets etc.)
DECOMMISSIONING THE MACHINE
•The decommissioning of the machine must be
performed exclusively by personnel trained,
qualified and authorized to perform such
operation.
•Start the disassembly of hydraulic
components only after the same, the hydraulic
oil and lubricants have fully cooled-off and
after all residual pressures have been
released, as described by the Repair
Instruction Manual.
•Prior to proceeding with disassembly
operations, comply with the GENERAL
SAFETY RULES and drain each components
of the machine filled with fluids, both in the
reservoirs and the relevant systems.
