CHANGE THE OIL FILTER

Change the oil filter the first time after 25 hours of
operation. Then, under normal operating conditions,
change the oil filter after every other oil change. If the
engine is operated under heavy load or in high ambi-
ent temperatures, change the oil filter more frequently.
See Table D.3 for recommended maintenance inter-
vals.
Change the oil filter as follows:
1. Drain the oil from the engine and allow the oil filter
to drain.
2. Remove the old filter (spin it off) and discard it.
Wipe off the filter mounting surface and adapter.
3. Apply a thin coat of new oil to the rubber gasket on
the new oil filter.
4. Spin the new filter onto the mounting adapter until
the gasket just touches the mounting surface, then
turn it down another 1/2 to 3/4 turn. Do not over-
tighten the new filter.
5. Refill the engine with the proper amount and type of
oil as described in the Change the Oil section,
above. Start the engine and check for leaks around
the filter element. Correct any leaks (usually by
retightening the filter, but only enough to stop leaks)
before placing the RANGER 9 back in service.

6. If there are no leaks, stop the engine and recheck
the oil level. If necessary, add oil to bring the level
up to the FULL mark, but do not overfill.
FUEL: At the end of each day's use, refill the
fuel tank to minimize moisture condensation
and dirt contamination in the fuel line. Do
not overfill; leave room for the fuel to
expand.
Use only fresh, unleaded gasoline with octane rating
87 or higher. Gasoline/alcohol blends are approved for
use with your engine as long as the blend does not
exceed 10% ethyl alcohol by volume. Other gaso-
line/alcohol blends are not approved, and their use
may damage fuel system and engine parts.
FUEL FILTER: Your engine may be equipped with an
in-line fuel filter. Inspect the fuel filter periodically and
replace it if it appears dirty.
