MAINTENANCE
CLEAN AND INSPECT RADIATOR FINS, OIL COOLER FINS, AFTERCOOLER FINS AND
CONDENSER FINS
If compressed air, high-pressure water, or steam hits your body directly or dirt is sent flying by the com-
pressed air, high-pressure water, or steam, there is danger of personal injury. Always wear protective
glasses, dust mask, and other protective equipment.
NOTICE
When using compressed air for cleaning, blow it keeping some distance to avoid damaging the fins. Dam-
age on the fins can cause water leakage and overheating. In a dusty job site, check the fins every day,
regardless of the maintenance interval.
1. Remove cover (1).
2. Loosen screw (2) and pull up net (3).
3. Clean net (3). (it is to be installed again, as instructed in the
step 8.)
4. Remove 5 bolts (4), then move bracket (5) to the side and
make a gap between radiator fins (6) and oil cooler fins (7).
5. Inspect the front and rear of radiator fins (6), oil cooler fins
(7), after-cooler fins (8) and condenser fins (9) for dirt, dust,
dry leaves, etc. Blow them away with compressed air, if
any. Steam or water may be used instead of compressed
air.
6. Check the rubber hose. Replace with a new one if the
hose is found to have cracks or to be hardened by aging.
In addition, check the hose clamps for looseness.
7. Remove undercover (10) and blow the mud, dirt, and
leaves that have been cleaned off to the outside.
8. Push in cleaned net (3) back to the original place and
secure it with screw (2).
9. Secure bracket (5) with bolt (4).
10. Remove the cover (1) and undercover (10).
