SPARK PLUG MAINTENANCE

ALWAYS use the Westinghouse OEM or compatible
non-resistor-type spark plug. Use of resistor-type spark
plug can result in rough idling, misfire, or may prevent
the engine from starting.
Inspect and clean the spark plugs after every 100 hours of
use or six months. Replace the spark plugs after 300 hours
of use or every year.
1. Place the generator on a level surface and allow the
engine to cool.
2. Remove the spark plug boots by firmly pulling the boot
directly away from the engine.
3. Clean the area around the spark plugs.
4. Remove the spark plugs with the included spark plug
socket wrench.
NEVER apply any side load or move the spark plug
laterally when removing the spark plug.
5. Inspect the spark plugs. Replace if electrodes are
pitted, burned, or the insulator is cracked. Only use a
recommended replacement plug.
6. Measure the spark plug electrode gap with a wire-type
feeler gauge. If necessary, correct the gap by carefully
bending the side electrode.
Spark plug gap: 0.024 – 0.032 in. (0.60 – 0.80 mm)

7. Carefully install each spark plug finger tight, then tighten
as additional 3/8 to 1/2 turn with the spark plug wrench.

SPARK ARRESTOR SERVICE

Allow the muffler to cool completely before servicing the
spark arrestor. Check and clean the spark arrestor after
every 100 hours of use or six months. Failure to clean the
spark arrestor will result in degraded engine performance.
1. Place the generator on a level surface.
2. Carefully remove the carbon deposits from the spark
arrestor screen with a wire brush. The spark arrestor
must be free of breaks and tears. Use compressed air
to clear removed deposits.

FUEL FILTER

Replace the fuel filter after 100 hours of use.
Note: Have an appropriate gasoline container and rags
ready to catch residual fuel in the filter and fuel line.
1. Allow the generator to cool completely.
2. Turn the fuel valve to the OFF position.
3. Note the orientation of the fuel filter. Using pliers, remove
the fuel line clamps and remove the fuel filter.
4. Install the new fuel filter in the reverse order of removal.
