This section includes information about simple main­
tenance which includes the following tasks:

• Changing engine oil.
• Changing oil filter.
• Changing the air cleaner.
• Cleaning the air intake screen.

CHECKING ENGINE OIL LEVEL
Check engine crankcase oil level at least every eight
hours of operation, or before each use (Figure 3).
• 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 8 for
recommended oils.

CHANGE ENGINE OIL
Change engine oil after the first 8 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, clean area around
oil drain plug and remove oil drain plug (Figure 4). Drain
oil completely into a suitable container.
• When oil has drained, install and lighten drain plug.
• Remove oil dipstick and fill crankcase with the recom­
mended oil (See Page 8). The engine crankcase can hold
about 1 quart (950ml). DO NOT FILL ABOVE “FULL"
MARK.
CHANGE OIL FILTER
Replace the engine oil filter after the first 8 hours of
operation, every 50 operating hours thereafter.
• Turn oil filter counterclockwise to remove (Figure 4).
• 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.
NOTE: Check the oil level and fill to FULL mark on
dipstick after checking for leaks. The filter will retain
some oil.
ENGINE AIR CLEANER
Paper Filter: Once every 25 operating hours or once
each year (whichever comes first), clean or replace
the paper filter (Figure 5). Follow these steps:
• Remove air cleaner cover, then remove paper filter.
• Clean air filter by gently tapping it on a solid surface. If
the filter is too dirty, replace it with a new one. Dispose of
the old filter properly.
• Clean air cleaner cover then insert new paper filter into
cover and assemble them to the base of the air cleaner.
