4.11 Maintenance procedure
Every 500 hours service
Clean and inspect radiator fins, oil cooler fins and condenser 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 dan-
ger of serious injury. Use safety glasses, dust mask, or other
protective equipment.
NOTE
When using compressed air, if the nozzle is brought too near the
fins, the fins may be damaged. Use compressed air from a rea-
sonable distance to prevent damage to the fins.
Do not direct the jet directly at the core. If the fins are damaged,
it will cause leakage of water and overheating. On dusty job
sites, inspect fins every day, regardless of the maintenance
interval.
1. Open engine hood.
2. Inspect the front and rear of the oil cooler fins (4), radiator
fins (7), after-cooler fins (8), and condenser fins (9) for dirt,
dust, dry leaves, etc. Blow them away with compressed air.
Steam or water may be used instead of compressed air.
3. Check the rubber hoses. Replace it with a new one, if the
hose is found to have cracks or to be hardened by age. Also
check the hose clamps for looseness.
4. Remove cover (10) from underneath and dispose of the dirt,
dust, dry leaves, etc., which have fallen on it.
