MAINTENANCE
SERVICE PROCEDURE
CLEAN AND INSPECT RADIATOR FINS, OIL COOLER FINS
WARNING
If compressed air, high-pressure water, or steam hit your body directly, or they cause dirt or dust to be blown up, there is a hazard
of serious injury. Always use safety glasses, dust mask, or other protective equipment.
NOTICE
When using compressed air, keep the air nozzle at a distance to prevent damage to the fins. Especially for the aftercooler, blow
the air from 300 mm (11.8 in) or more, and at a 45 degree angle.
To prevent damage to the fins, apply compressed air from an appropriate distance. Damaged fins may cause water leakage or
overheating. On dusty sites, check the fins daily, regardless of the maintenance interval.
Inspect and clean the radiator fins and oil cooler fins, using the maintenance ladder.
1. Open the engine hood and the door on the left side at the rear
of the machine.
2. Blow off with compressed air dirt, dust, tree leaves, etc.
clogging the radiator fins and oil cooler fins (1). Clean the net
in front of the oil cooler at the same time.
Steam or water will do instead of compressed air.
3. Check the rubber hose. Replace with a new one if the hose is
found to have cracks or to be hardened by ageing.
Also, check hose clamps for looseness.
