Personal safety
Carefully read this Manual before proceeding with main-
tenance, repairs, refuelling or other machine operations.
Repairs have to be carried out only by authorized and in-
structed staff; specific precautions have to be taken when
grinding, welding or when using mallets or heavy ham-
mers.
Non-authorized persons are not allowed to repair or carry
out maintenance on this machine. Do not carry out any
work on the equipment without prior authorization.
Ask your employer about the safety instructions in force
and safety equipment.
Nobody should be allowed in the cab during machine
maintenance unless he is a qualified operator helping
with the maintenance work.
If it is necessary to move the equipment to carry out re-
pairs or maintenance, do not lift or lower the equipment
from any other position than the operator’s seat.
TULI12WEX2004AA 1
Never carry out any operation on the machine when the
engine is running, except when specifically indicated.
Stop the engine and ensure that all pressure is relieved
from hydraulic circuits before removing caps, covers,
valves, etc.
All repair and maintenance operations should be carried
out with the greatest care and attention.
Service stairs and platforms used in a workshop or in the
field should be built in compliance with the safety rules in
force.
Any functional disorders, especially those affecting the
safety of the machine, should therefore be rectified im-
mediately.
DANGER
Unexpected movement!
Make sure parking brake is applied. Secure
machine with wheel chocks.
Failure to comply will result in death or serious
injury.
D0013A
TULI12WEX2005AA 2
Before performing any work on the machine, attach a
maintenance in progress tag. This tag can be applied on
the left-hand control lever, safety lever or cab door.

Emergency
Be prepared for emergencies. Always keep a fire extin-
guisher and first aid kit readily available. Ensure that the
fire extinguisher is serviced in accordance with the man-
ufacturer’s instructions.
SMIL12WEX0174AA 3
Equipment
Wear close fitting clothing and safety equipment appropri-
ate for the job:
• Safety helmet
• Safety shoes
• Heavy gloves
• Reflective clothing
• Wet weather clothing
If working conditions require, the following personal safety
equipment should be on hand:
• Respirators (or dust proof masks)
• Ear plugs or acoustic ears protections
• Goggles with lateral shield or masks for eye protection
Do not wear rings, wristwatches, jewelry, unbuttoned or
flapping clothing such as ties, torn clothes, scarves, open
jackets or shirts with open zips which could get caught into
moving parts.
TULI12WEX2008AA 4
Engine - Radiator
Never leave the engine running in enclosed spaces with-
out proper ventilation which is able to evacuate toxic ex-
haust gases- Keep the exhaust manifold and tube free
from combustible materials.
Do not refuel with the engine running, especially if hot, as
this increases fire hazard in case of fuel spillage.
Never attempt to check or adjust the belts when the en-
gine is running.
Never lubricate the machine with the engine running.
TULI12WEX2009AA 5

10. INTRODUCTION
Pay attention to rotating components and do not allow
anyone to approach these areas to avoid becoming en-
tangled.
Hands, clothing or tools getting caught in the fan blades or
engine belts, can cause amputations, violent hemorrages
and generate conditions of grave danger. For this reason
avoid touching or approaching all rotating or moving parts.
A surging spray of the coolant from the radiator can cause
serious burns and scalds.
Before checking the coolant level, shut-off the engine
and allow machine to cool down the radiator and hoses.
Slowly unscrew the cap to release any residual pressure.
TULI12WEX2010AA 6
If it is necessary to remove the cap while engine is hot,
wear safety clothes and equipment, then loosen the cap
slowly to relieve the pressure gradually.
When checking the fuel, oil and coolant levels, use lights
and lamps explicitly designated as explosion proof. If
these types of lamps are not used, fires or explosions may
occur.
TULI12WEX2011AA 7
Hydraulic systems
Jets of fluids under pressure can penetrate the skin caus-
ing serious injuries.
Avoid this hazard by relieving pressure before disconnect-
ing hydraulic or other lines.
Relieve the residual pressure by moving the hydraulic
control levers several times.
Tighten all connections before applying pressure.
To protect the eyes wear a facial shield or safety goggles.
Protect your hands and body from possible jets of fluids
under pressure.
Swallowing hydraulic oil is a severe health hazard.
TULI12WEX2012AA 8

11. INTRODUCTION
When hydraulic oil has been swallowed, avoid vomiting,
but consult a doctor or go to a hospital.
If an accident occurs, see a doctor familiar with this type
of injury immediately.
Any fluid penetrating the skin must be removed within a
few hours to avoid serious infections.
Flammable splashes may originate because of heating
near lines with fluids under pressure, resulting in serious
burns. Do not weld or use torches near lines containing
fluids or other flammable materials.
Lines under pressure can accidentally be pierced when
the heat expands beyond the area immediately heated.
Arrange for temporary fire resistant shields to protect
hoses or other components during welding or torch use.
Have any visible leakage repaired immediately.
Discharged oil pollutes the environment. Soak up any
oil that has spilled with a proper binding agent. Sweep
up binding agent and dispose of it separately from other
waste.
Never search for leakages with fingers; instead, use a
piece of cardboard and always wear goggles.
Never repair a damaged line; always replace it. Replace
hydraulic hoses immediately on detecting any damaged
or moist areas.
Always store hydraulic oil in the original containers.
