SPARK PLUG MAINTENANCE

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.
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.
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.

MAINTENANCE

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. Slide in screwdriver into side slot and remove screw
holding clamp (A) on spark arrestor. Pull out spark
arrestor assembly.
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.

STORAGE

Proper storage preparation is required for trouble-free
operation and generator longevity.
Gasoline stored for as little as 30 days can deteriorate,
causing gum, varnish, and corrosive buildup in fuel lines,
fuel passages, and the engine. This corrosive buildup
restricts the flow of fuel, which can prevent the engine
from starting after a prolonged storage period. The use
of fuel stabilizer significantly increases the storage life of
gasoline. Full-time use of fuel stabilizer is recommended.
Follow the manufacturer's instructions for use.
STORAGE TIME
Less than 1 month
2 to 6 months
