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.

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.
