9. Maintenance

F20

■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.

IMPORTANT

•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

F22

■SPARK ARRESTER

•The muffler is equipped with a spark arrester to prevent 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 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.

■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.

■AIR INLET NET

IMPORTANT

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

F23

(1)

•Blowing air is taken in from the air inlet net. When air flow has dropped down during operation, stop the engine and inspect the air inlet net for blocking by obstacles.

•Note that failure to remove any such obstacles may result in the engine becoming overheated and damaged.

WARNING

F21

US-14

•Before starting operation, always make sure to check if the muffler is properly held by three bolts (F21 (2)). (Fastening Torque : 8 to 12 N·m)

•Also make sure that the speak arrester and the diffuser are properly attached with four bolts (F21 (1)). (Fastening Torque : 2 to 3 N·m)

•Even if one of seven bolts is loose, it may result in engine catching on fire.
