need to add or change the pump oil.
6.4 CLEANING THE AIR-FILTER
WARNING!
Using gasoline or other flammable solvents can cause a fire or
explosion. Do not operate this product without an air filter.
A dirty air filter will restrict air flow into the carburetor. Clean and maintain the air
filter regularly, especially in dusty areas.
Note
Never run the pressure washer without an air filter, doing so will quickly
degrade the engine.
1. Loosen the air filter cover. Remove the air filter housing and elements and
inspect for cleanliness.
2. Clean the foam air filter with soap and water or solvent and let dry.
3. Soak the foam filter in clean engine oil.
4. Gently squeeze and then pat out all excess oil and reinstall.
5. Replace either filter if it is damaged.
