check for loose or damaged components. Replace all
bent or damaged air cleaner components.

air cleaner components could allow unltered air into

Note: Service the air cleaner more often under
extremely dusty, dirty conditions.

blade control switch, move the motion control
levers to the brake position, stop the engine, and

Lift the cover and remove the hose clamp securing
the air cleaner assembly to the engine (
