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 screw (2) and pull up net (3).
3.
Clean net (3) that you pulled up.
4.
Remove bolts (4) (6 places) and move bracket (5) to make
clearance between radiator fin (6) and oil cooler fin (7).
5.
Check the front and rear sides of radiator fins (6), oil cooler
fins (7), aftercooler fins (8), and condenser fins (9). If there
is any mud, dirt, leaves, etc. 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 (radiator, oil cooler, after-
cooler, fuel cooler, air conditioner condenser), main-
tain sufficient distance from the machine when per-
forming the work. If steam cleaning (high-pressure ma-
chine 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.
6.
Visually check the rubber hose connected to the heat exchange equipment. Check the hose clamp for
looseness as well.
