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. Reinstall the air filter element inside the air filter
housing while taking care to ensure that the
element is correctly positioned.
11. Reinstall 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 clockwise to the ON
position.
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 29)
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.

MAINTENANCE
8. Pour the contents of the fuel strainer into
a suitable waste receptacle. Low pressure
compressed air can be used if necessary for
blowing onto the outside of the strainer mesh to
remove any trapped fine grit.
NOTICE
Never dispose of fuel or fuel contaminants by
dumping either of them into a sewer, on the
ground, or into groundwater or waterways. Always
be environmentally responsible. Follow the
guidelines of the government agencies for proper
disposal of hazardous materials. Consult local
authorities or reclamation facility.
9. Reinstall the fuel strainer by hand inside the
filler hole on top of the fuel tank (see Figure 30).
Make sure it is fully inserted into the opening
(see Figure 8).

10. Reinstall the fuel cap.

SPARK PLUG MAINTENANCE

Tools required: Phillips head screwdriver, spark plug
socket wrench, spark plug gap tool or feeler gauge,
and wire brush.
The spark plug should be checked and cleaned after
every 100 hours of use or 6 months and then replaced
after 250 hours of use or every year.
1. Stop the generator and let it cool for several
minutes if it's been running.
2. Move the generator to a flat, level surface.
3. Remove the engine access cover (see Figure 26).
4. Remove the spark plug boot by firmly pulling it up
and away from the engine (see Figure 31).
