6. Wash the air filter element in a solution of
household detergent and warm water or
alternatively in non-flammable solvent. Slowly
squeeze the foam in the liquid for a thorough
cleaning action. Then remove the foam and
squeeze out the liquid.
NOTICE
NEVER twist or tear the air filter element during
cleaning or drying. Apply only a slow and firm
squeezing action.

fresh water and applying a slow squeezing
action.
MAINTENANCE
NOTICE
Never dispose of the used cleaning solution or
solvent by dumping it into a sewer, on the ground,
into groundwater or into a waterway. Always be
environmentally responsible. Follow the guidelines
of the governmental agencies for proper disposal
of hazardous materials. Consult local authorities
or reclamation facility.
8. Dry the air filter element by repeatedly applying
a slow firm squeezing action.
9. Coat the air filter element in clean engine oil and
then thoroughly squeeze out the excess liquid.
10. Re-install the air filter element inside the air filter
housing while taking care to ensure that the
element is correctly positioned.
11. Re-install the air filter and engine access covers.

FUEL STRAINER MAINTENANCE

Check and clean the fuel strainer after every
100 hours of use or 6 months. It is recommended
that this maintenance task also be performed each
time when filling with fuel from any source other
than directly from a service station bowser.
1. Stop the generator, if running.
2. Allow the generator to cool down until the
muffler access cover is cool to the touch.
3. Remove the generator to a flat surface.
4. Clean area around the fuel cap.
5. Turn the fuel cap vent to the ON position, if
equipped.
6. Remove the fuel cap and set it aside on a clean
surface.
7. Remove the fuel strainer by hand from inside the
filler hole on top of the fuel tank (see Figure 39)
taking care not to tear or otherwise damage the
fine mesh screen. Keep the fuel strainer vertical
so that any trapped liquid or solids do not spill
onto the generator.
