4.8.10.g CLEANING THE OUTSIDE OF THE RADIATOR
WARNING
q
If compressed air, steam or water are directed against a person, they may cause injuries.
Wear goggles and safety shoes.
To clean the outside of the radiator it is first necessary to loosen
the screws (2) and remove the guard (1) positioned on the front of
the engine hood. Use a 17 mm hex wrench.
The cleaning must be carried out using a compressed air jet and,
if necessary, with a low pressure water or steam washing cycle;
the specific detergents available on the market can certainly be
used, provided that the instructions given on the package are
followed and that the washed parts are carefully dried.
After washing, put back the front guard (1).
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
Clean the outside of the radiator whenever the radiator is
dirtied, even if accidentally, with oil, diesel oil, greasy or
oily substances.
q
If the machine is used in dusty places, clean the radiator
and the heat exchanger more frequently, in order to prevent
the fins from clogging.
