4.9.6.d CHECKING AND CLEANING THE FINS OF THE RADIATOR AND OF THE
EXCHANGER
WARNING
q
If compressed air, steam or water hit someone, they may cause serious injury.
Always wear a visor and safety shoes.
1. Open the radiator cover. For details, see paragraph "3.2.7
RADIATOR COVER"
2. The radiator-exchanger assembly (1) must be cleaned with a
jet of compressed air and, if necessary, with a low-pressure
water or steam washing cycle; the specific products available
on the market can be used, provided that the instructions giv-
en on the package are followed 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 cleaning operation whenever the radiator or
the heat exchanger are accidentally dirtied with oil, diesel
oil or 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.
