SECTION 00 - SAFETY PRECAUTIONS

4 SECTION 00 - SAFETY PRECAUTIONS
SAFETY RULES
ZCarefully follow specified repair and maintenance
procedures.
ZDo not wear rings, wristwatches, jewels, unbut-
toned or flapping clothing such as ties, torn
clothes, scarves, open jackets or shirts with open
zips which could get hold into moving parts.
We advise to use approved safety clothing such as
anti-slipping footwear, gloves, safety goggles, hel-
mets, etc.
ZNever carry out any repair on the machine if some-
one is sitting on the operator’s seat, except if they
are certified operators to assist in the operation to
be carried out.
ZNever operate the machine or use attachments
from a place other than sitting at the operator’s
seat.
ZNever carry out any operation on the machine
when the engine is running, except when specifi-
cally indicated.
ZStop the engine and ensure that all pressure is re-
lieved from hydraulic circuits before removing
caps, covers, valves, etc.
ZAll repair and maintenance operations should be
carried out with the greatest care and attention.
ZService stairs and platforms used in a workshop or
in the field should be built in compliance with the
safety rules in force.
ZDisconnect the batteries and label all controls to
warn that the Machine is being serviced. Block the
machine and all equipment which should be
raised.
ZNever check or fill fuel tanks and accumulator bat-
teries, nor use starting liquid if you are smoking or
near open flames as such fluids are flammable.
ZBrakes are inoperative when they are manually re-
leased for maintenance purposes. In such cases,
the machine should be kept constantly under con-
trol using blocks or similar devices.
ZThe fuel filling gun should remain always in contact
with the filler neck.
Maintain this contact until the fuel stops flowing
into the tank to avoid possible sparks due to static
electricity buildup.
ZUse exclusively specified towing points for towing
the machine. Connect parts carefully.
Ensure that foreseen pins and/or locks are steadily
fixed before applying traction.
Do not stop near towing bars, cables or chains
working under load.
ZTo transfer a failed machine, use a trailer or a low
loading platform trolley if available.
ZTo load and unload the machine from the transpor-
tation mean, select a flat area providing a firm sup-
port to the trailer or truck wheels. Firmly tie the
machine to the truck or trailer platform and block
wheels as required by the forwarder.
ZFor electrical heaters, battery-chargers and similar
equipment use exclusive auxiliary power supplies
with a efficient ground to avoid electrical shock
hazard.
ZAlways use lifting equipment and similar of appro-
priate capacity to lift or move heavy components.
ZPay special attention to bystanders.
ZNever pour gasoline or diesel oil into open, wide
and low containers.
ZNever use gasoline, diesel oil or other flammable
liquids as cleaning agents. Use non-flammable
non-toxic proprietary solvents.
ZWear protection goggles with side guards when
cleaning parts using compressed air.
ZDo not exceed a pressure of 2.1 bar, in accordance
with local regulations.
ZDo not run the engine in a closed building without
proper ventilation.
ZDo not smoke, use open flames, cause sparks in
the nearby area when filling fuel or handling highly
flammable liquids.
ZDo not use flames as light sources when working
on a machine or checking for leaks.
ZMove with caution when working under a Machine,
and also on or near a Machine. Wear proper safety
accessories:
helmets, goggles and special footwear.
ZDuring checks which should be carried out with the
engine running, ask an assistant to sit at the oper-
ator’s seat and keep the service technician under
visual control at any moment.
In case of operations outside the workshop, drive
the machine to a flat area and block it. If working
on an incline cannot be avoided, first block the Ma-
chine carefully. Move it to a flat area as soon as
possible with a certain extent of safety.
ZRuined or plied cables and chains are unreliable.
Do not use them for lifting or trailing. Always han-
dle them wearing gloves of proper thickness.
ZChains should always be safely fastened. Ensure
that fastening device is strong enough to hold the
load foreseen. No persons should stop near the
fastening point, trailing chains or cables.
ZThe working area should be always kept CLEAN
and DRY. Immediately clean any spillage of water
or oil.
ZDo not pile up grease or oil soaked rags, as they
constitute a great fire hazard. Always place them
into a metal container. Before starting the Machine
or its attachments, check, adjust and block the op-
erator’s seat. Also ensure that there are no per-
sons within the Machine or attachment operating
range.
ZDo not keep in your pockets any object which
might fall unobserved into the Machine’s inner
compartments.

SECTION 00 - SAFETY PRECAUTIONS 5
ZWhenever there is the possibility of being reached
by ejected metal parts or similar, use protection
eye mask or goggles with side guards, helmets,
special footwear and heavy gloves. Wear suitable
protection such as tinted eye protection, helmets,
special clothing, gloves and footwear whenever it
is necessary to carry out welding procedures. All
persons standing in the vicinity of the welding proc-
ess should wear tinted eye protection. NEVER
LOOK AT THE WELDING ARC IF YOUR EYES
ARE NOT SUITABLY PROTECTED.
ZMetal cables with the use get frayed. Always wear
adequate protections (heavy gloves, eye protec-
tion, etc.).
ZHandle all parts with the greatest caution. Keep
your hands and fingers far from gaps, moving
gears and similar. Always use approved protective
equipment, such as eye protection, heavy gloves
and protective footwear.
START UP
ZNever run the engine in confined spaces which are
not equipped with adequate ventilation for exhaust
gas extraction.
ZNever bring your head, body, arms, legs, feet,
hands, fingers near fans or rotating belts.
ENGINE
ZAlways loosen the radiator cap very slowly before
removing it to allow pressure in the system to dis-
sipate. Coolant should be topped up only when the
engine is stopped or idle if hot.
ZDo not fill up fuel tank when the engine is running,
mainly if it is hot, to avoid ignition of fires in case of
fuel spilling.
ZNever check or adjust the fan belt tension when the
engine is running. Never adjust the fuel injection
pump when the machine is moving.
ZNever lubricate the machine when the engine is
running.
ELECTRICAL SYSTEMS
ZIf it is necessary to use auxiliary batteries, cables
must be connected at both sides as follows: (+) to
(+) and (-) to (-). Avoid short-circuiting the termi-
nals. GAS RELEASED FROM BATTERIES IS
HIGHLY FLAMMABLE. During charging, leave the
battery compartment uncovered to improve venti-
lation. Avoid checking the battery charge by
means of “jumpers” made by placing metallic ob-
jects across the terminals. Avoid sparks or flames
near the battery area. Do not smoke to prevent ex-
plosion hazards.
ZPrior to any service, check for fuel or coolant leaks.
Remove these leaks before going on with the work.
Do not charge batteries in confined spaces. En-
sure that ventilation is appropriate to prevent acci-
dental explosion hazard due to build-up of gasses
relieved during charging.
ZAlways disconnect the batteries before performing
any type of service on the electrical system.
HYDRAULIC SYSTEMS
ZSome fluid slowly coming out from a very small
port can be almost invisible and be strong enough
to penetrate the skin. For this reason, NEVER USE
YOUR HANDS TO CHECK FOR LEAKS, but use
a piece of cardboard or a piece of wood for this
purpose. If any fluid is injected into the skin, seek
medical aid immediately. Lack of immediate medi-
cal attention, serious infections or dermatitis may
result.
ZAlways take system pressure readings using the
appropriate gauges.
WHEELS AND TYRES
ZCheck that the tyres are correctly inflated at the
pressure specified by the manufacturer. Periodi-
cally check possible damages to the rims and
tyres.
ZKeep off and stay at the tyre side when correcting
the inflation pressure.
ZCheck the pressure only when the machine is un-
loaded and tyres are cold to avoid wrong readings
due to over-pressure. Do not reuse parts of recov-
ered wheels as improper welding, brazing or heat-
ing may weaken the wheel and make it fail.
ZNever cut, nor weld a rim with the inflated tyre as-
sembled.
ZTo remove the wheels, block both front and rear
Machine wheels. Raise the Machine and install
safe and stable supports under the Machine in ac-
cordance with regulations in force.
ZDeflate the tyre before removing any object caught
into the tyre tread.
ZNever inflate tyres using flammable gases as they
may originate explosions and cause injuries to by-
standers.
REMOVAL AND INSTALLATION
ZLift and handle all heavy components using lifting
equipment of adequate capacity. Ensure that parts
are supported by appropriate slings and hooks.
Use lifting eyes provided to this purpose. Take
care of the persons near the loads to be lifted.
ZHandle all parts with great care. Do not place your
hands or fingers between two parts. Wear ap-
proved protective clothing such as safety goggles,
gloves and footwear.
ZDo not twist chains or metal cables. Always wear
protection gloves to handle cables or chains.
