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 : 70~110 kg·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 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.

F13
•Blowing air is taken in from the air inlet screen. When air flow has dropped down during operation, stop the engine and inspect the air inlet screen 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 screen at the air intake of the blower. Before each use, check that, the screw
(1)is securely tightened and is free from any damage.
