AIR FILTER
NOTE: Replace the filter if damaged.
When the filter indicator lamp is activated on the instrument panel, it
means that the filter should be cleaned or replaced. A dirty filter will
cause insufficient power and wear of the engine. In order to ensure the
service life and normal operation of the engine, the air filter must be
maintained carefully and periodically.
The air filter should be checked and maintained after each 5,000-mile
increment. When the vehicle runs in a heavy dust environment, the
replacement cycle of the filter should be shortened. The engine must be
off when the intake system is being serviced. Do not start the engine
once the filter has been removed. Restart only after the filter has been
replaced.
To remove the cover, take off the 4 snap clips and remove the outer
filter and lid. Remove the dust in the unloading valve. Clean the filter by
tapping lightly with hand, wooden tool, or by blowing air into the filter
with an air compressor.
Remove the inner filter butterfly-nut. Clean the filter by tapping lightly
with hand, wooden tool, or by blowing air into the filter with an air
compressor.
CAUTION
Do not blow air on the outside surface of the filter core.
When using compressed air, be sure the air pressure is lower than 72
psi (496 kPa). Blow the air from inside the filter to the outside, until the
dust is no longer visible.
Clean the surface using a clean, dry cloth. The filter should be checked
by using an examining lamp to make sure there is no damage before
installing it. Check for damage or cracks on the sealing ring.
NOTE: Do not start the engine without the air filter in place.
