CHECKING ENGINE OIL LEVEL
Check engine crankcase oil level at least every eight
hours of operation, or before each use (Figure 7).
• Be sure the generator is as level as possible.
• Remove oil dipstick and wipe dry with clean, lint-free
cloth.
• Install and tighten oil dipstick, then remove again.
• Oil level should be within the cross-hatched area on the
dipstick. If necessary, remove oil fill cap and add the rec­
ommended oil to the cross-hatched area only. DO NOT
FILL ABOVE CROSS-HATCHED AREA.
• Install and tighten oil dipstick and oil fill cap before oper­
ating the engine.
NOTE: See “Engine Oil Requirements” on Page 9 for
recommended oils.
CHANGE ENGINE OIL
Change engine oil after the first 25 hours of operation.
Thereafter, change oil every 50 operating hours.
Change oil more frequently if operating consistently
under heavy load or at high ambient temperatures.
• Warm up engine for at least five minutes, then shut down.
• With engine still warm from running, remove oil drain plug
(Figure 8). Drain oil completely into a suitable container.
When oil has drained, install and tighten oil drain plug.
Remove oil fill cap (Figure 7) and fill crankcase with the
recommended oil (See Page 9). The engine crankcase
can hold about 1.5 U.S. quarts (1.6 liters). DO NOT FILL
ABOVE THE CROSS-HATCHED AREA.
Install and tighten oil fill cap before operating engine.

CHANGE OIL FILTER
Replace the engine oil filter after the first 25 hours of
operation, every 100 operating hours thereafter.
• Turn oil filter counterclockwise to remove (Figure 9).
• Coat gasket of new filter with engine oil.
• Turn new filter clockwise until its gasket contacts lightly
with the filter adapter. Then tighten an additional 3/4 to
one turn.
• Run engine and check for leaks.
NOTE: Check the oil level and fill to the cross-hatched
area on dipstick after checking for leaks. The filter will
retain some oil.
