DANGER
Burns danger
Attention to burns. Engine reduction gear oil and
the hydraulic system, pipes, engine and other
components heat up when the vehicle is used.
Wait until all parts cool down before beginning
maintenance or repair work.
• Fluids such as fuel or hydraulic oil under pressure
can penetrate the skin and eyes causing serious
injuries. Take care to avoid these risks when
repairing or doing maintenance work on the
vehicle.
• Discharge the pressure (using the hydraulic levers
of the distributors) before disconnecting or
repairing pipes and hydraulic parts.
DANGER
When a hydraulic pipe needs to be disconnected,
slowly loosen the fittings to discharge residual
pressure.
DANGER
Pressurized liquids danger.
Hydraulic energy accumulators are mounted on
the vehicle. Before intervening on them, make
sure to discharge any internal pressure. Danger of
high pressure oil splashes.
• Before restarting the engine, ensure that all
connections have been properly tightened.
• Use a piece of cardboard to check for any leaks;
make sure your body is adequately protected
against pressurized fluids.
• Any fluids that penetrate the skin must be
removed surgically. Should there be an accident,
seek medical attention immediately.
DANGER
Corrosive substances danger
Never touch air conditioning coolant.
• If it comes into contact with eyes, air conditioning
coolant may cause blindness; it may cause
freezing if it comes into contact with skin.
• When cleaning with compressed air, serious injury
may be caused by flying particles.
• Always wear protective goggles, a dust mask,
gloves and other protective equipment.
WARNING
Adjusting and/or dismantling balancing
and safety valves can be dangerous.
One of the above-mentioned valves may be
removed only when the concerned jack is at rest

All other operations must be carried out by
qualified, authorized personnel only.
NOTE
Only use lubricants suggested by DIECI; never
utilize used lubricants.
