before installing. If the element is broken or shrunk, replace with a new one. (F17)

A clogged air filter may increase fuel consumption while cutting down the engine power.
And operate the brushcutter without the air filter or with a deformed filter element will
quickly ruin the engine.

• Disconnect the strainer from fuel pipe and clean sludge from strainer. (F18)

A clogged fuel filter may cause poor acceleration of the engine.

■ SPARK PLUG

clean the spark plug and replace with a new one as required. (F19)

■ GEAR CASE

• Supply ZENOAH genuine grease at every 25 hours of use.
• Remove the cutter holders to arrange for old grease to exit. (F20)

■ MAINTENANCE BEFORE STORAGE

• Old fuel left in the carburetor may cause starting failure. When a series of operation

finished, make sure to empty the fuel tank and drain the carburetor.

• Check all parts and the functions. If the failured or damaged parts have been found,

replace them with new ones.
