MAINTENANCE
AIR CLEANER CHECK/CLEANING/
REPLACEMENT
A dirty air filter will restrict air flow to the carburetor,
reducing engine performance. If the engine is operated
in dusty areas, clean the air cleaner more often than
specified in the MAINTENANCE SCHEDULE.
• Operating the engine without the air filters or with the
filter installed loosely will allow dirt to enter the
engine, causing rapid engine wear. Install the air
filters securely.
Remove the air cleaner cover bolt (6 x 40 mm) (2) [1]
and air cleaner cover [2].
Remove the paper element [3] from the air cleaner case
[4].
Remove the foam element [5] from the air cleaner
cover.
Check both air cleaner elements for holes or tears and
replace if damaged.
Clean both air cleaner elements if they are to be reused
(page 3-4).
Installation is in the reverse order of removal.
ELEMENT CLEANING
FOAM
Clean the filter [1] in warm soapy water, rinse, and allow
to dry thoroughly, or clean with a non-flammable
solvent and allow to dry thoroughly.
Dip the filter in clean engine oil, and squeeze out all the
excess oil.
Excess oil will restrict air flow through the foam element
and may cause the engine to smoke at startup.
PAPER
Tap the element [1] lightly several times on a hard
surface to remove excess dirt, or blow compressed air
lightly (206 kPa (2.11 kgf/cm
2
, 30 psi) or less) through
the paper filter from the inside out. Never try to brush
the dirt off; brushing will force dirt into the fibers.
