1. Close the choke (pull out knob) before removing the air cleaner cover to
prevent debris from entering the carburettor.
2. Loosen the wing nut and remove air cleaner cover.
3. Before removing the filters, clean the accumulated dust from the filters and
air cleaner base plate with a soft brush or by gently blowing (Do not use
compressed air).
4. The third (nylon mesh) filter should be removed only when cleaning is
necessary. When re-installing, be sure filter base is properly installed in the
rubber connector.
5. Clean the foam (first) filter and nylon (third) filter in water/detergent
solution. Wrap the foam filter in a clean cloth and squeeze (Do not wring)
dry.
6. If foam (first) filter is to be oiled, soak it in clean 20W or 30W engine oil.
Again wrap the filter in a clean dry cloth and squeeze (Do not wring) until
the filter appears dry.
7. Clean the main filter by gently tapping filter flat against a flat surface. Do
not brush or wetten the paper, harsh cleaning methods will damage the
filter. Fasten firmly the main filter mounting bolts.
8. Examine all three filters for cracks or tears. Replace any filter that is, or
appears, clogged or damaged after cleaning.
Dust from cutting must be prevented from entering
the engine. The three (3) filters in the Air Cleaner
System can do this if they are properly maintained
and correctly installed. The foam, first filter when
used dry should be removed and cleaned each
time the fuel tank is refilled. If the foam filter is oiled
[recommended to prolong main (paper) filter life],
cleaning may be required more frequently if a
noticeable drop in power due to a clogged air filter
is noted.
IMPORTANT
Excess oil will contaminate the paper (main)
filter, shortening its life.
