MAINTENANCE
2.
Press down lever (2) and open fan guard (3).
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 machine.
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 with a new one. Also check
and tighten all loose hose clamps.
5.
After cleaning, close fan guard (3) and rear grille (1).
