MAINTENANCE
CHANGING THE ENGINE OIL
See Figure 19.
For optimal performance, change the engine oil according
to the figures specified in the maintenance schedule or the
engine manual (if applicable). When using the generator
under extreme, dirty, dusty conditions or in extremely hot
weather, change the oil more frequently.
NOTE: Change the oil while the engine is warm but not
hot. Warm engine oil drains more quickly and thoroughly
than cool lubricant. Contact with hot lubricant will cause
serious burns.
l Turn the generator off and allow the engine to cool for
30 minutes.
l Place the generator on a level surface in a well-ventilated
area.
l Turn the lock knob to the unlocked position.
l Remove the engine service cover.
l Clean the area around the oil dipstick.
l Slowly unscrew and remove the oil dipstick.
l Place an oil pan (or suitable container) under the oil fill/
drain hole.
l Tilt the generator to drain the oil.
l After the oil has drained completely, place the generator
in an upright position.
l Refill the oil as described in the Operations section.
l Replace the oil dipstick and hand-tighten.
l Clean up any spilled oil.
l Install the engine service cover and turn the lock knob to
the locked position to secure.
CLEANING/REPLACING THE SPARK PLUG
See Figure 20.
NOTICE
ALWAYS use the Westinghouse OEM
or compatible non-resistor-type spark plug. Use of re-
sistor-type spark plug can result in rough idling, mis-
fire, or may prevent the engine from starting.
Make sure the spark is clean and properly gapped. To clean
or replace your spark plug:
l Turn the generator off and allow the engine to cool for
30 minutes.
l Place the generator on a level surface in a well-ventilated
area.
l Lift the spark plug service door to gain access to the spark
plug area.
l Remove the spark plug boot by firmly pulling the spark
boot directly away from the engine.
l Clean the area around the spark plug.
l Remove the spark plug with the included spark plug socket
wrench.

NOTICE
Never apply any side load or move the
spark plug laterally when removing the spark plug.
l Inspect the spark plug. Replace if electrodes are pitted,
burned, or the insulator is cracked. Only use a recom-
mended replacement plug.
l 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: 0.028 - 0.031 in. (0.7 - 0.8 mm)
l Carefully install the spark plug finger tight, then tighten
as additional 3/8 to 1/2 turn with the spark plug wrench.
l Install the spark plug boot and close the spark plug service
door.
