MAINTENANCE
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 hose. 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.
CLEAN INTERNAL AND EXTERNAL AIR FILTERS
OF AIR CONDITIONER SYSTEM
If compressed air, high-pressure water, or steam hit your
body directly, or they cause dirt or dust to be blown up, there
is danger of serious injury. Use safety glasses, dust mask, or
other protective equipment.
NOTICE
The interval for cleaning the filter is 500 hours, but if the
machine is used on an extremely dusty job site, reduce the
maintenance interval and clean the filter more frequently.
REMARK
If the filter is clogged, the air flow is reduced and a muffled
sound can be heard from the air conditioner unit.
