GENERAL MAINTENANCE
Air conditioning system
WARNING: Never attempt to open the air conditioning system. Liquid refrigerant can cause severe and
painful frostbite. Contact your dealer, who is experienced in servicing and handling of refrigerants.
Air conditioned cab
Besides being able to provide an optimum temperature
in the cab, this system also lowers the degree of humid-
ity in the air.
Safety notes
The air conditioner is a safe system that is able to ensure
lasting and risk-free use. However, it is important to com-
ply with certain simple precautions (listed below) in order
to prevent possible accidents.
• Never work on the conditioning system yourselves.
Always contact the specialised technicians of the
Assistance Service.
• Keep naked flames well away from the air conditioning
system (Fig.131) as leaking coolant could give rise to
a deadly gas: phosgene..
• The mixture of oil and coolant in the air conditioning
system is under pressure.
Never ever loosen any unions or tamper with the
pipes.
For the same reason, you must never unscrew the
compressor's oil level check plug.
• Coolant can freeze the skin and particularly the eyes.
Proceed in the following way if accidents occur:
– if coolant has splashed into the eyes, wash them out
immediately with a few drops of mineral oil, then
continue to wash them with a solution of boric acid
and water (one teaspoon of acid in 1/4 of a cup of
water) and immediately seek medical help;
– areas frozen by coolant fluid can be treated by pro-
gressively warming the injured zone with cold water
and then applying a greasy cream.
However, always seek medical help if such accidents
occur.
•
Keep the air conditioning system well away from heat
sources as explosions could occur.
System check
The cab air conditioner is equipped with a system to
protect the compressor from high or low refrigerant
pressures.
Have your conditioning system checked once a year by
specialised personnel at your Dealer's.
DANGER: Always wear protective clothing in
case of leaks. Coolant can injury the eyes.
The coolant produces a toxic gas if it contacts
a flame.
