4.9.6.c CHECKING THE OIL LEVEL IN THE FINAL REDUCTION GEARS
WARNING
q
Soon after the machine has been stopped, the engine oil is very hot and may cause burns; let the oil
cool down to 40–45° C before carrying out any check.
q
Loosen the cap slowly to release any residual pressure.
1. The check must be carried out on each reduction gear, with
the drain plug (P) in low position and perpendicular to the
ground. If necessary, move the machine slightly until reach-
ing the specified position, which is indispensable for an accu-
rate check.
2. This is a visual check and serves to make sure that the lubri-
cant reaches the height of the hole (G); if this is not the case,
top up by proceeding as explained in paragraph "4.9.7.b
CHANGING THE OIL IN THE FINAL REDUCTION GEARS"
and using the oil prescribed in the lubricant chart (see "4.4
FUEL, COOLANT AND LUBRICANTS").
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.
