Selection of the correct grade and type of engine oil
greatly affects the performance of the generator,
especially when starting. Before selecting replacement
oil for an oil change, consider the anticipated operating
conditions the generator may be exposed to. Choose the
appropriate weight of oil for anticipated temperatures
from Chart C. If temperatures are expected to fluctuate
between extremes prior to the next oil change interval,
use of synthetic oil is recommended. Use of oil meeting a
minimum American Petroleum Institute (API)
classification of SJ is advised.
Engine oil changes are recommended at the
maximum intervals given in the Periodic Maintenance
Table. When operating in hot or dusty conditions shorter
change intervals may be necessary. To change the
engine oil and oil filter, the listed procedure is
recommended.
1. Warm up the engine oil by running a cold engine for
a few minutes, then shutting it off. Start and stop the
engine by moving the control panel mode switch
between the RUN and OFF positions. Insure the
mode switch is in the OFF position before continuing
the oil change.
2. Place an oil drain pan capable of holding three (3)
quarts under the end of the oil drain hose (
A
).
3. Remove the oil fill cap (
B
) and place in a convenient
location. While holding the end of the oil drain hose
(
A
) in the drain pan, slowly open the oil drain valve
(
C
) by turning the handle clockwise until the valve is
fully open. Allow the engine oil to completely drain
into the drain pan.
4. When the engine oil is completely drained, close the
valve (
C
) by turning the handle fully counterclockwise.
5. Place the drain pan underneath the spin on oil filter
(
D
), then remove the filter by turning it
counterclockwise. Once loose, drain all of the oil
from the filter into the drain pan.
6. Apply a light film of oil to the gasket on the new oil
filter, then screw the filter onto the adapter until the
gasket lightly touches the adapter face. Tighten the
filter an additional ¾ to 1 turn.
7. Refill the engine with 1.5 qt (1.4 liters) of new engine
oil through the engine oil fill cap (
B
). Refer to the
engine oil recommendations on chart C for the
proper grade of oil. Replace the oil fill cap (
B
),
then start the engine and check for leaks.
8. Stop the engine and check the engine oil level as
outlined on page 26. Add oil as required to bring
the oil to the proper level on the dipstick.
At the intervals given in the maintenance schedule
table, check the oil cooler and lines for leaks. If leaks are
detected, replace clamps, fittings or hoses as necessary.
Also visually inspect the oil cooler for debris clogging the
cooler fins. If the cooler is blocked, use low pressure air
or water to dislodge the blocking material.

Chart C
•
State and federal agencies have determined
that contact with used engine oil can cause
cancer or reproductive toxicity. Take care to
limit skin contact and breathing of vapors as
much as possible. Use rubber gloves and wash
exposed skin.

Any attempt to crank or start the engine before
it has been properly serviced with the
recommended oil will result in an engine failure
that is not covered by warranty.
