2. Wash the air filter in fresh, non flammable cleaning
solution (ex. warm soapy water) and then dry.
Saturate the air filter in 2 cycle oil or the equivalent.
Squeeze the air filter to distribute the oil completely
and to remove any excess oil.
■ FUEL FILTER
* A clogged fuel filter may cause poor acceleration of
the engine. Check periodically to see if the filter is
clogged with dirt. The filter can be taken out of the
fueling port using a small wire hook. Disconnect the
filter assembly from the fuel pipe and unhook the
retainer to disassemble it. Clean the components
with gasoline.

■ SPARK PLUG
• The spark plug may gather carbon deposits on its
firing end with reasonable use. Remove and inspect
the spark plug every 25 hours and clean the
electrodes as necessary with a wire brush. The spark
gap should be adjusted to .025 in (0.6~0.7mm).
• Plug manufacturers recommend replacing the plug
twice a year to avoid unexpected plug failure in a job.
REPLACEMENT PLUG IS A NGK CMR7H OR
CHAMPION RZ7C.
