MAINTENANCE
3.
Blow off mud, dirt, leaves, etc. in radiator fins (4) with com-
pressed air.
NOTICE
Steam or water may be used instead of the com-
pressed air.
However, when using the powerful steam cleaning
equipment (high-pressure machine wash) for the heat
exchange equipment (radiator and cooler), keep a suf-
ficient distance to the target.
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.
Check the rubber hoses. If any hose is cracked or hardened by age, replace it with a new one. Also check
and tighten all the loose hose clamps.
5.
After cleaning, close the fan guard (3) and rear grille (1).

1.
Open the engine side covers (1) and (2) on the right and
left sides of the machine.
