This section includes information about simple mainte­
nance which includes the following tasks:
• Checking engine oil level.
• Changing engine oil.
• Changing oil filter.
• Engine air cleaner service.
• Cleaning the air intake screen.
• Cleaning spark plugs.
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.
Figure 9 — Oil Dipstick and Fill Tube
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.
