7. Tilt the generator over to drain oil into a waste
oil pan or container (see Figure 33).
8. Allow oil to drain completely.
9. Fill crankcase with new oil following the steps
outlined in Adding Engine Oil.
10. Re-install the oil fill plug and engine or oil
access cover.
An alternate and superior method for draining is to
use an oil extractor vacuum pump to remove the
used oil via the oil fill plug hole.
NOTICE
Never dispose of used engine oil by dumping
the oil into a sewer, on the ground, or into
groundwater or waterways. Always be
environmentally responsible. Follow the guidelines
of the government agencies for proper disposal of
hazardous materials. Consult local authorities or
reclamation facility.

AIR FILTER MAINTENANCE

WARNING
Never use fuel or other flammable
solvents to clean the air filter. Use only
household detergent and warm water
or alternatively a non-flammable
solvent.
NOTICE
Do not operate the generator without an air filter
element or with a damaged air filter element.
This will allow dirt to enter the engine and cause
accelerated wear.
