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.
Note that using any spark plugs other than those
designated may result in the engine failing to
operate properly or in the engine becoming
overheated and damaged.
To install the spark plug, first turn the plug until it is
finger tight, then tighten it a quarter turn more with a
socket wrench.
MUFFLER
Inspect periodically, the muffler for loose fasteners,
any damage or corrosion. If any sign of exhaust
leakage is found, do not use the blower and have it
repaired immediately.
Note that failing to do so may result in the
engine catching on fire.
Before starting operation, always make sure to
check if the muffler is properly held by three bolts
(F19 (2)). (Fastening Torque : 8 to 12 N·m)
Also make sure that the speak arrester and the
diffuser are properly attached with four bolts (F19
(1)). (Fastening Torque : 2 to 3 N·m)
Even if one of seven bolts is loose, it may result in
engine catching on fire.
