2. Air cleaner service
A dirty air cleaner will restrict air flow to the carburetor. To prevent
carburetor malfunction, service the air cleaner regularly. Service more
frequently when operating the pump in extremely dusty areas.
Never use gasoline or low flash point solvents for cleaning. They are
flammable and explosive under certain conditions.
CAUTION:
Never run the pump without the air cleaner. Rapid engine wear will
result from contaminants such as dust and dirt being drawn into the
engine.
1. Move the choke lever to the CLOSED (upwards) position.
2. Remove the air cleaner cover by unhooking the latch tab on the top
of the air cleaner cover and its two lower tabs.
3. Clean the air cleaner element in warm soapy water, rinse, and allow
to dry thoroughly. Or clean in nonflammable solvent and allow to
dry.
4. Dip the air cleaner element in clean engine oil, then squeeze out all
excess oil. The engine will smoke when started if too much oil is left
in the foam.
5. Wipe dirt from the air cleaner body and cover, using a moist rag. Be
careful to prevent dirt from entering the carburetor.
6. Reinstall the air cleaner element.
7. Reinstall the air cleaner cover by inserting the lower tabs, and the
latch tab.
