CHECKING OIL LEVEL
Oil level should be checked prior to each use or at
least every 8 hours of operation. Keep oil level
maintained.
CHANGING ENGINE OIL AND OIL FILTER
Change oil after first 8 hours of operation. Change oil
and oil filter every 50 hours thereafter. If you are using
your generator under extremely dirty or dusty
conditions, or in extremely hot weather, change oil
more often.
Change oil while engine is still warm from running, as
follows:
• Clean area around oil drain plug.
• Remove oil drain plug and oil fill plug and drain oil
completely into a suitable container.
• When oil has completely drained, Install oil drain
plug and tighten securely.
• Place a suitable container beneath the oil filter and
turn filter counterclockwise to remove. Discard
according to local regulations.
• Coat gasket of new filter (p/n 70185) with engine
oil. turn filter clockwise until gasket contacts tightly
with filter adapter. Then tighten an additional 3/4
turn.

or once each year, whichever comes first. This will
help your engine to start easier and run better.

Important: If you feel uncomfortable about doing this
procedure or you don't have the proper tools, please
take your generator in to the nearest service center to
have the head bolts re-torqued. This is a very
important step to insure the longest life for your
engine.
NOTE: Only perform this adjustment after the first 50
hours of operation. The head bolts will need no further
adjustment.
