7.4 CLEANING THE AIR-FILTER
WARNING!
Using gasoline or other flammable solvents can cause fire or
explosion. Do not operate this product without an air filter.
A dirty air lter will restrict air ow into the carburetor. Clean and maintain the air
lter regularly, especially in dusty areas.
NOTE
 Never run the pressure washer without an air lter, doing so will quickly
degrade the engine.
1. Loosen top nut and remove the air lter cover. Remove the air lter
element.
2. Separate the foam pre-lter from the air lter element.
3. Inspect the paper lter inside the air lter element, shake lter or blow with
air to remove any dust and debris. Replace either lter if damaged.
4. Clean the foam pre-lter with soap and water or solvent and let dry
completely.
5. Wearing gloves, add new engine oil to the foam pre-lter. Work oil into foam
lter until saturated.
6. Squeeze and repeatedly use a towel to pat out excess oil. The result should
be a very lightly oiled pre-lter, if excess oil remains in the foam lter it can
seep through to the paper lter and damage it.
7. Add foam pre-lter back to air lter element and reinstall onto engine.
