Safety rules
Personal safety
This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all
safety messages that follow this symbol to avoid possible death or injury.
Throughout this manual you will find the signal words DANGER, WARNING, and CAUTION followed by special in-
structions. These precautions are intended for the personal safety of you and those working with you.
Read and understand all the safety messages in this manual before you operate or service the machine.
DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.
WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION, used with the safety alert symbol, indicates a hazardous situation which, if not avoided, could
result in minor or moderate injury.
FAILURE TO FOLLOW DANGER, WARNING, AND CAUTION MESSAGES COULD RESULT
IN DEATH OR SERIOUS INJURY.
Machine safety
NOTICE: Notice indicates a situation which, if not avoided, could result in machine or property damage.
Throughout this manual you will find the signal word Notice followed by special instructions to prevent machine or
property damage. The word Notice is used to address practices not related to personal safety.
Information
NOTE: Note indicates additional information which clarifies steps, procedures, or other information in this manual.

6. INTRODUCTION
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.
Not 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 is allowed to seat on the operator’s place 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.

7. INTRODUCTION
Emergency
Be prepared for emergencies. Always keep at disposal on
the machine a first aid kit and a fire extinguisher. Make
sure that the fire extinguisher is serviced in accordance
with the manufacturer’s instructions.
SMIL12WEX0174AA 4
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 environment condition require it following personal
safety equipment should be at hand:
• Respirators (or dust proof masks)
• Ear plugs or acoustic ears protections
• Goggles with lateral shield or masks for eyes protection
Do not wear rings, wristwatches, jewels, 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 5
Engine - Radiator
Never leave the engine run in closed spaces without venti-
lation and not able to evacuate toxic exhaust gases. Keep
the exhaust manifold and tube free from combustion ma-
terials.
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 6

8. INTRODUCTION
Pay attention to rotary pieces and do not allow to anyone
to approach to avoid becoming entangled.
If hands, clothes or tools get caught in the fan blades or in
the transmission belt, this can cause amputations, violent
tears and generate condition of serious danger; for this
reason avoid touching or to come close to all rotary or
moving parts.
A violent jet of the coolant from the radiator can cause
damages and scalds.
If you are to check the coolant level, you have to shut-off
the engine previously and to let cool down the radiator and
its pipes. Slowly unscrew the cap to release the inside
pressure.
TULI12WEX2010AA 7
If necessary, remove the cap with hot engine, wear safety
clothes and equipment, then loosen the cap slowly to re-
lieve the pressure gradually.
When checking the fuel, oil and coolant levels, use ex-
clusively explosion proof classified lamps. If this kind of
lamps are not used fires or explosions may occur.
TULI12WEX2011AA 8
Hydraulic systems
Splashes of fluids under pressure can penetrate the skin
causing 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 splashes of
fluids under pressure.
Swallowing hydraulic oil is a severe health hazard.
TULI12WEX2012AA 9
47494131A 11/03/2013

9. 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 few
hours to avoid serious infections.
Flammable splashes may originate because of the heat
near pipes with fluids under pressure, with the result of
serious scalds for the persons hit. Do not weld or use
torches near pipes containing fluids or other flammable
materials.
Pipes under pressure can accidentally be pierced when
the heat expands beyond the area immediately heated.
Arrange for fire resistant temporary shields to protect
hoses or other components during welding.
Have any visible leakage repaired immediately.
Escaping oil pollutes the environment. Soak up any oil
that has escaped with a proper binding agent. Sweep
up binding agent and dispose of it separately from other
waste.
Never search for leakages with the fingers, but use a piece
of cardboard and always wear goggles.
Never repair damaged piping; always replace it. Replace
hydraulic hoses immediately on detecting any damage or
moist areas.
Always store hydraulic oil in the original containers.
