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

•Check the air cleaner before use.

A clogged air filter may increase fuel consumption while cutting down the engine power.

•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.
