D-2 MAINTENANCE D-2
Use 4-stroke motor oil that meets or exceeds the
requirements for API service classification SG or SH.
Always check the API SERVICE label on the oil con-
tainer to be sure it includes the letters SG or SH.
SAE 10W-30 is recommended for general, all-temper-
ature use, -5 F to 104 F (-20 C to 40 C).
See Engine Owner ’ s Manual for more specific infor-
mation on oil viscosity recommendations.
Wash your hands with soap and water after handling
used oil.
Please dispose of used motor oil in a manner that is
compatible with the environment. We suggest you
take it in a sealed container to your local service sta-
tion or recycling center for reclamation.
Do not throw it in the trash, pour it on the ground or
down a drain.
OIL FILTER CHANGE
1. Drain the engine oil.
• Remove the oil filter, and drain the oil into a suitable
container. Discard the used oil filter.
• Clean the filter mounting base, and coat the gasket
of the new oil filter with clean engine oil.
• Screw on the new oil filter by hand, until the gasket
contacts the filter mounting base, then use an oil fil-
ter socket tool to tighten the filter an additional 1/2 to
7/8 turn.
• Refill the crankcase with the specified amount of the
recommended oil. Reinstall the oil filler cap.
• Start the engine and check for oil filter leaks.
• Stop the engine, and check the oil level. If neces-
sary, add oil to the upper limit mark on the dipstick.
• Air Cleaner - With normal operating conditions, the
maintenance schedule for cleaning and re-oiling the
foam pre-filter is every 25 hours and replacement of
the air cleaner filter every 100 hours. More fre-
quent servicing is required with dusty operating
conditions. Refer to the maintenance section of the
Engine Owner
’ s Manual for more information.
• Refer to the maintenance section of the Engine
Owner ’ s Manual for the maintenance schedule,
spark plug servicing, cooling system servicing, and
fuel filter replacement.
• Blow out the machine with low pressure air period-
ically. In particularly dirty locations, this may be
required once a week.
• Output Selector and Polarity Switch contacts
should not be greased. To keep contacts clean,
rotate the switch through its entire range frequently.
A good practice is to turn the handle from maximum
to minimum setting twice each morning before
starting to weld.
