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.

With normal operating conditions, the maintenance
schedule for cleaning and re-oiling the foam pre-filter

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

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

from maximum to minimum setting twice each
morning before starting to weld.
