To clean the air filter
Clean the air filter regularly from dirt and dust. This
prevents carburetor malfunctions, starting problems,
loss of engine power, wear to engine parts and more
fuel consumption than usual. Clean the air filter at an
interval of 40 hours of operation or less if it is heavy
operation conditions.
1. Loosen the fasteners that holds the air filter cover in
position.
