WARNING
Make sure that the engine has stopped and is cool before performing any service to the blower. Contact with rotating blower fan or hot muffler may result in a personal injury.
■ AIR CLEANER
• Never operate the blower without an air filter or with a deformed or broken filter element because unfiltered dusty air will quickly ruin the engine.
• Check the air cleaner before use.
A clogged air filter may increase fuel consumption while cutting down the engine power.
• Never clean a paper filter by striking it with or against another object. The filter may be damaged and resultant dust contamination can diminish engine performance.
