MAINTENANCE
SERVICE PROCEDURE
CLEAN RADIATOR FINS
1. Remove bolts (1) at the center and four corners of the radiator
grill, then open radiator grill (2).
2. Clean the radiator fins clogged with mud, dust and leaves with
compressed air. Steam or water may be used instead of
compressed air.However, when performing powerful steam
cleaning (high-pressure machine wash) of the heat exchange
equipment (radiator), maintain sufficient distance from the
machine when performing the operation. If steam cleaning
(high-pressure machine wash) is performed at close range,
there is danger that the internal fins of the heat exchange
equipment may be deformed, and this will cause early clogging
and breakage.
REMARK
Use compressed air to blow off any dirt embedded in the radiator
fins. It is also possible to blow with compressed air from the side
holes on both sides (3) of the radiator guard.
CLEAN OIL COOLER FINS
1. Open the engine side cover on the right side of the machine.
2. Blow off dirt, dust and dry leaf shreds that clog the oil cooler
fins, with compressed air. Steam or water may well be used for
this purpose instead of compressed air.However, when
performing powerful steam cleaning (high-pressure machine
wash) of the heat exchange equipment (oil cooler), maintain
sufficient distance from the machine when performing the
operation. If steam cleaning (high-pressure machine wash) is
performed at close range, there is danger that the internal fins
of the heat exchange equipment may be deformed, and this
will cause early clogging and breakage.
REMARK
Check the hydraulic cooler hoses. If any hose is cracked or
hardened by age, replace with a new hose. Also check and tighten
all loose hose clamps.
