AIR FILTER MAINTENANCE

Never use gasoline or other flammable
solvents to clean air filter. Use only
household detergent soap to clean the air
filter.
The air filter must be replaced after every 50 hours of
use or every year (frequency should be increased if
pressure washer is operated in a dusty environment).
NOTE: The air filter cannot be cleaned with
compressed air.
1. Turn off the pressure washer and let it cool for
several minutes if running.
2. Move the pressure washer to a flat, level surface.
3. Loosen the clip or nut holding the cover in place
and open the air cleaner cover.

5. Wash the foam air filter elements by submerging
the elements in a solution
of household detergent soap and warm water.
Slowly squeeze the foam to thoroughly clean.

8. Dry the air filter elements by again applying a slow
firm squeezing action.
