9. Maintenance
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 elec-
trodes 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 CHAMPION
RZ7C OR NGK CMR7H.
IMPORTANT
• Note that using any spark plugs other than those
designated may result in the engine failing to oper-
ate 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
WARNING
• 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.
IMPORTANT
• Before starting operation, always make sure to
check if the muffler is properly held by three bolts to
the cylinder. (Fastening Torque : 8~12 N·m)
• Even if one bolt out of three bolts is loose, the muf-
fler may get loose during operation which may result
in engine catching on fire.
GB-12
PROCEDURES TO BE PERFORMED AFTER
EVERY 100 HOURS OF USE
1. Remove the muffler, insert a screwdriver into the
vent, and wipe away any carbon buildup. Wipe
away any carbon buildup on the muffler exhaust
vent and cylinder exhaust port at the same time.
2. Tighten all screws, bolts, and fittings.
SPARK ARRESTER
• The muffler is equipped with a spark arrester to pre-
vent red hot carbon from flying out of the exhaust
outlet. Periodically inspect and clean as necessary
with a wire brush. In the State of California it is re-
quired by law (Section 4442 of the California Pulic
Resources Code) to equip a spark arrester when
a gas powered tool is used in any forest covered,
bush covered, or grass covered unimproved land.
