To examine the air intake screen
A clogged air intake screen decreases the blow force
and increases the temperature of the engine. An
increased temperature can result in engine failure.
1. Stop the engine.
2. Examine the air intake screen for damages and
make sure that it is attached correctly.
3. Remove dirt, leaves and unwanted materials from
the air intake screen.
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.
