3.
Check the front and rear sides of radiator fins (5), oil cooler
fins (6), fuel cooler fins (7), and condenser fins (8) (ma-
chine equipped with air conditioner). If there is any mud,
dirt, leaves, etc. stuck to the fins, blow it off with com-
pressed air.
NOTICE
Steam or water may be used instead of the com-
pressed air. However, when performing powerful
steam cleaning (high-pressure machine wash) of the
heat exchange equipment (radiator, oil cooler, and fuel
cooler), maintain sufficient distance from the machine
when performing the work.
If steam cleaning (high-pressure machine wash) is per-
formed at close distance, there is a danger that the in-
ternal fins of the heat exchange equipment may be de-
formed, and this will cause early clogging and break-
age of the equipment.
4.
Close the cooling cover (3).
5.
Close the engine rear cover (1).
