MAINTENANCE PROCEDURE
NOTICE
When using compressed air for cleaning, blow it keeping some distance to avoid damaging the fins.
Damage 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.
Open cover (1).
2.
Loosen screws (3) (2 places) and pull up net (2).
3.
Clean net (2) that you pulled up.
4.
Check the front and rear surfaces of oil cooler fins (4), ra-
diator fins (5), aftercooler fins (6), air conditioner condens-
er fins (7), and fuel cooler fins (8). If there is any mud, dirt,
or leaves stuck to the fins, blow it off with compressed air.
NOTICE
Steam or water may be used instead of the com-
pressed air. However, when performing powerful
steam cleaning (high-pressure machine wash) of the
heat exchange equipment (oil cooler, radiator, after-
cooler, air conditioner condenser, or fuel cooler),
maintain sufficient distance from the machine when
performing the work. 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 may be deformed, and this will cause early
clogging and breakage of the equipment.
5.
Visually check the rubber hose connected to the heat exchange equipment. Check the hose clamp for
looseness as well.
If the rubber hose is cracked or become fragile, ask your Komatsu distributor for replacement.
If the hose clamp is loose, tighten it.
