7. 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.

8. 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.
