A dirty air filter decreases engine per-
formance and increases fuel consump-
tion and harmful emissions. Always
clean after every 5 hours of operation.
Cleaning the air filter:

around it to keep debris from falling
into the carburetor
chamber when
the cover is removed.
2. Remove parts as illustrated.
NOTE: Do not clean filter in gasoline
or other flammable solvent.
Doing so
can create a fire hazard or produce
harmful evaporative
emissions.

5. Apply a few drops of oil to the filter;
squeeze filter to distribute oil.

sure the engine starts easier and runs
better. Set spark plug gap at 0.025
inch. Ignition timing is fixed, nonadjust-
able.
