REPLACEMENT PLUG
NGK BPMR7A
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 and crank case. (Fastening Torque : 8~12 N·m)
•Also make sure that the spark arrester and the dif- fuser are properly attached with four bolts (Fastening Torque : 2~3 N·m)
•Even if one of seven bolts is loose, it may result in engine catching on fire.

(2) Spark Arrester
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.
NOTE
Fit the Spark Arrester on the pipe and tightly fix with the clip
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.
AIR INLET NET
IMPORTANT
•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 dam- aged.
