Oil Change Procedure
1. Stop the generator set.
2. To drain the oil, open the oil-drain valve. See
Section 1 for the valve location.
3. Drain the oil into a suitable container.
4. Allow ample time for all oil to drain.
5. Close the oil-drain valve.
6. Remove the oil-fill cap.
7. Replace the engine oil filter according to the
service schedule and the procedure in
Section 3.3.5.
8. Fill crankcase with oil. Section 1 shows the oil fill
location. See Figure 3-1 for oil selection and
Figure 3-3 for oil capacity. Replace the oil-fill cap.
9. Start the generator set and check for oil leaks.
10. Stop the generator set. Check the oil level. Add oil,
as necessary, to bring the level up to the Full mark.
Note: Too high an oil level causes high oil
consumption and engine carbonizing. Too
low a level damages the engine.
Note: Do not pollute the environment. Dispose of
used engine oil and other contaminants in a
safe, approved manner.
3.3.5 Oil Filter Change
Replace the oil filter at the interval specified in the
service schedule. Change the oil filter more frequently if
the generator set operates under dirty, dusty conditions.
Refer to the following procedure. See Section 1 for oil
filter location.
Oil Filter Change Procedure
1. Loosen the oil filter by turning it counterclockwise.
Remove the oil filter and use rags to clean up
spilled oil. Dispose of the oil filter in an approved
manner.
2. Clean the contact surface of the oil filter adapter.
3. Lightly lubricate the gasket surface of the new filter
with fresh engine oil. Thread the filter on the
adapter until the gasket makes contact and
hand-tighten the filter an additional one-half turn.
Wash hands after any contact with engine oil.
Note: If also performing an oil change, skip steps 4
and 5 and go back to oil change procedure.
4. Start the generator set and check for oil leaks.
5. Stop the generator set. Check oil level. Add oil, as
necessary, to bring level up to Full mark.
3.4 Gasoline Fuel System
3.4.1 Fuel Specifications
Use a clean, good-quality unleaded fuel with an octane
number of 87 or 89. Use fresh gasoline to ensure it is
blended for the season and to reduce the possibility of
the formation of gum deposits that could clog the fuel
system. Do not use gasoline left over from the previous
season.
Kohler Co. recommends unleaded fuel because it
leaves fewer combustion chamber deposits. Never mix
oil with fuel.
Note: Consult the engine owner’s manual for
oxygenated fuel recommendations.
3.4.2 Fuel Filter (Gasoline)
Clean/replace the gasoline fuel filter at the interval
specified in the service schedule.
Service more
frequently if rough operation suggests a clogged fuel
filter. Some models use an in-line fuel filter which cannot
be cleaned and requires replacement. Other models
have a fuel pump with an integral fuel filter which
requires cleaning at the specified interval.
