2-4 PERIODIC MAINTENANCE
MAINTENANCE AND TUNE-UP PROCEDURES
This section describes the servicing procedures for each item of
the Periodic Maintenance requirements.
AIR CLEANER
• Remove the air cleaner cover 1.
• Remove the air cleaner element 2.
• Carefully use air hose to blow the dust from the cleaner ele-
ment.

• Reinstall the cleaned or new air cleaner element in the
reverse order of removal.

Inspect every 6 000 km (4 000 miles, 12 months) and
replace every 18 000 km (11 000 miles, 36 months).
Always use air pressure on the engine side of the air
cleaner element. If air pressure is used on the other
side, dirt will be forced into the pores of the air cleaner
element thus restricting air flow through the air
cleaner element.
If driving under dusty condition, clean the air cleaner
element more frequently. The surest way to accelerate
engine wear is to use the engine without the element
or to use a ruptured element. Make sure that the air
cleaner is in good condition at all times. Life of the
engine depends largely on this component!
