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). For the Onan
engine, it is recommended that SAE 30 oil be used
above 82 F (27 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
• 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
RANGER 9
SLIP RINGS
A slight amount of darkening and wear of the slip rings
and brushes is normal. Brushes should be inspected
when a general overhaul is necessary. If brushes are
to be replaced, clean slip rings with a fine emery
paper.
Do not attempt to polish slip rings while engine is
running.
------------------------------------------------------------------------
• 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 frequent 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 for
spark plug servicing, cooling system servicing, and
and fuel filter replacement.
• Blowout the machine with low pressure air period-
odically. In particularly dirty locations, this may be
required once a week.
• Output Ranger Selector and Polarity Switches:
Switch contacts should not be greased. To keep
contacts clean, rotate the switch through its entire
range frequently. Good practice is to turn the handle
from maximum to minimum setting twice each
morning before starting to weld.
