Maintenance
■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 : 80~120kg·cm)
•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.
■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 Public Resources Code) to equip a spark arrester when a gas powered tool is used in any forest covered, brush covered, or grass covered unimproved land.
■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 damaged.
WARNING
•Never use the blower without the net of the blower. Before each use, check that the net is attached in place and is free from any damage.
