METHOD FOR CLEANING OIL COOLER FIN
1.
Open the engine side cover on the left side of the ma-
chine.
2.
Blow off mud, dirt, leaves, etc. in oil cooler fins with com-
pressed air.
Steam or water may be used instead of the compressed
air.
However, when performing powerful steam cleaning (high-
pressure machine wash) on the heat exchange equipment
(oil cooler), maintain sufficient distance when performing
the operation.
If steam cleaning (high-pressure machine wash) is performed at close distance, there is a danger that the
internal fins of the heat exchange equipment will be deformed, and this will cause early clogging and break-
age of the equipment.
3.
Perform the following check.
Check the rubber hoses. If they are cracked or fragile, replace them.
Check the hose clamps for looseness.
METHOD FOR CLEANING AFTERCOOLER FIN
1.
Open the engine side cover on the right side of the ma-
chine.
2.
Blow off mud, dirt, leaves, etc. in aftercooler fins (3) with
compressed air.
Steam or water may be used instead of the compressed
air.
However, when performing powerful steam cleaning (high-
pressure machine washing) of the heat exchanger (after-
cooler), maintain sufficient distance from the machine.
If steam cleaning (high-pressure machine wash) is per-
formed at close distance, there is a danger that the internal fins of the heat exchange equipment will be
deformed, and this will cause early clogging and breakage of the equipment.
