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 Remove the oil access cover.
l Place an oil pan (or suitable container) under the unit.
l Remove the rubber plug located beneath the oil drain
bolt.
l Remove the oil drain bolt.
l After the oil has drained completely, replace the oil drain
bolt and rubber drain plug.
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.
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 Remove the engine service cover.
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: 0.024 - 0.032 in. (0.6 - 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.
