7.3 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 generator without an air filter, doing so will quickly
degrade the engine.
1.
Unscrew and remove the air filter cover.
2.
Remove the foam filter.
3.
If the foam element is dirty, clean it in warm soapy water, rinse, and allow it
to dry thoroughly, or clean in non-flammable solvent and allow to dry.
4.
Dip the foam 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 filter.
5.
Wipe dirt from the air filter assembly and reinstall into the unit.
