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 des-
ignated 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
WARNING
• Inspect periodically, the muffler for loose fasteners,
any damage or corrosion. If any sign of exhaust leak-
age is found, do not use the blower and have it re-
paired 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 cyl-
inder. (Fastening Torque : 8~12 N·m)
• Even if one bolt out of three bolts is loose, the muffler
may get loose during operation which may result in
engine catching on fire.
PROCEDURES TO BE PERFORMED AFTER EV-
ERY 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 cylin-
der 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 out-
let. Periodically inspect and clean as necessary with
a wire brush. In the State of California it is required 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.
