Spark Plug Maintenance; Spark Arrestor Service - Westinghouse WGen9500c Manual De Usuario

DO NOT pollute. Follow the guidelines of the EPA or other
governmental agencies for proper disposal of hazardous
materials. Consult local authorities or reclamation facility.

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 plug after every 100 hours of
use or six months. Replace the spark plug 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 boot by firmly pulling the spark
boot directly away from the engine.
3. Clean the area around the spark plug.
4. Remove the spark plug 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 plug. 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 the spark plug finger tight, then tighten
as additional 3/8 to 1/2 turn with the spark plug wrench.
8. Attach the spark plug boot.

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. Remove the cover screws and the muffler cover. Use a
screw driver to remove the spark arrestor.
3. Carefully remove the carbon deposits from the spark
arrestor screen with a wire brush. The spark arrestor
must be free of breaks and tears. Replace the spark
arrestor if damaged.
4. Reinstall the spark arrestor and muffler cover.
FUEL VALVE MAINTENANCE
The fuel valve is equipped with a fuel sediment cup, screen,
and o-ring. The fuel valve does not require servicing if the
unit is properly maintained with fresh, clean fuel. If fuel-
related troubleshooting is required, perform fuel valve
maintenance.
1. Allow the generator to cool completely.
2. Turn the fuel valve to the OFF position.
3. Remove the sediment cup from the fuel valve. Remove
the o-ring and screen.
4. Wash the sediment cup, o-ring, and screen in a
nonflammable solvent. Dry thoroughly.
