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.

NOTE: See “Engine Oil Requirements” on Page 11 for rec­
ommended oils.

CHANGE ENGINE OIL
Change engine oil after the first 25 hours of operation (after
the 25 hour break-in period, Page 9). Thereafter, change oil
every 100 operating hours. Change oil more frequently if oper­
ating 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 11). The engine crankcase can hold
about 1.5 quarts. 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 opera­
tion, 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 lightly with
the filter adapter. Then tighten with an additional 3/4 to one
turn by hand.
• Run engine and check for leaks.
