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 electrodes as necessary with a wire brush. The spark gap should be adjusted to .025 in (0.6 to 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. Check that the spark plug is fitted with a suppressor.

•To install the spark plug, first turn the plug with your hands until it is tight, then tighten it a quarter turn more with a socket wrench.

■MUFFLER

WARNING

•Periodically inspect the muffler for loose fasteners, damage or corrosion. If any sign of exhaust leakage is found, do not use the blower and have it repaired immediately.

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 prevent red hot carbon from flying out of the exhaust outlet. Periodically inspect and clean as necessary with a wire brush.
