Air Filter Cleaning - Husqvarna W 40P Operator's Manual

MAINTENANCE

AIR FILTER CLEANING

A dirty air filter will restrict air flow to the carburetor, reducing engine
performance. If you operate the pump in very dusty areas, clean the air
filter more frequently than specified in the Maintenance Schedule (see
page 26).
1. Clean the air filter in warm soapy water, rinse, and allow to dry
thoroughly. Or clean in nonflammable solvent and allow to dry.
2. Dip the air filter in clean engine oil, and then squeeze out all excess
oil. The engine will smoke when started if too much oil is left in the
foam.
3. Wipe dirt from the air cleaner base and cover, using a moist rag. Be
careful to prevent dirt from entering the air duct that leads to the
carburetor.
