CHECKING ENGINE OIL LEVEL
Check engine crankcase oil level at least every eight
hours of operation, or before each use (Figure 9).
• 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 should be at dipstick FULL mark. If necessary, add the
recommended oil to the FULL mark only, DO NOT FILL
ABOVE “FULL’ MARK.
• Install and tighten oil dipstick cap before operating 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
(after the 25 hour break-in period. Page 6). Thereafter,
change oil every 100 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 cap from oil
drain hose (Figure 10). Drain oil completely into a suitable
container.
• When oil has drained, install and tighten drain hose cap.
Remove oil dipstick and fill crankcase with the recom­
mended oil (See Page 9). The engine crankcase can hold
about 1.7 liters. DO NOT FILL ABOVE “FULL” MARK.
Install and tighten dipstick cap before operating engine.
CHANGE OIL FILTER
Replace the engine oil filter after the first 25 hours of
operation, every 200 operating hours thereafter.
• Turn oil filter counterclockwise to remove (Figure 11).
• Coat gasket of new filter with engine oil.
• Turn new filter clockwise until its gasket contacts tightly
with the filter adapter. Then tighten with an additional 3/4
to one turn by hand.
• Run engine and check for leaks.
NOTE: Check oil level and fill to full mark after check­
ing for leaks. Filter will retain some oil.
