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.
