4.8.10.h CLEANING THE OUTSIDE OF THE A/C CONDENSER
(only for machines with air conditioner)
WARNING
q
If compressed air, steam or water are directed against a person, they may cause injuries. Always wear
an eye shield and safety shoes.
The condenser (1) must be cleaned at the same at as the radiator
(see "4.8.10.g CLEANING THE OUTSIDE OF THE RADIATOR").
The condenser (1) must be cleaned with a jet of compressed air
and, if necessary, with a low-pressure water or steam washing cy-
cle; the specific products available on the market can certainly be
used, provided that the instructions given on the package are fol-
lowed and that the washed parts are carefully dried.
IMPORTANT
q
Do not use products containing even a slight quantity of
oily substances, since these facilitate the adhesion of dust,
which affects the heat exchange adversely.
q
Carry out this operation whenever the condenser is dirtied,
even if accidentally, with oil, diesel oil, greasy or oily sub-
stances.
To clean the radiator, rotate the condenser (1) on the lower
pins.
q
If the machine is used in dusty places, clean the condenser
more frequently, in order to prevent the fins from clogging.
