MAINTENANCE
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.

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.
BATTERY REPLACEMENT
Keep battery terminals covered at all times. The
generator is shipped with a lithium ion (Li-Ion) battery.
Exposed metal positive and negative terminals can
short-circuit when they come into contact with metal
objects, igniting the cell's internal materials and forcibly
expelling burning contents, resulting in fires, explosions,
serious injuries and even death.
1. Loosen and remove the bolts securing the battery hold-
down plate and remove the plate.
2. Disconnect the quick-connect plugs and remove the
battery from the unit.
3. Disconnect the quick-disconnect cable leads from the
battery.
4. On the replacement battery, connect the white (-) quick-
connect cable to the battery negative terminal. Slide the
rubber boot over the connection hardware.
