Oil Sentry

Some engines are equipped with an optional Oil
Sentry ™ oil pressure switch. If the oil pressure
decreases below an acceptable level, the Oil Sentry
will either shut off the engine or activate a warning
signal, depending on the application.
NOTE: Make sure the oil level is checked BEFORE
EACH USE and is maintained up to the "F"
mark on the dipstick. This includes engines
equipped with Oil Sentry

Change Oil and Oil Filter

Change Oil
Change oil after every 100 hours of operation. Refill
with service class SG, SH, SJ or higher oil as specified
in the "Viscosity Grades" table (Figure 2) on page 4.
Change the oil while the engine is still warm. The oil
will flow more freely and carry away more impurities.
Make sure the engine is level when filling, checking,
and changing the oil.
Change the oil as follows (see Figure 7):
1. To keep dirt, debris, etc., out of the engine, clean
the area around the oil fill cap/dipstick before
removing it.
2. Remove one of the oil drain plugs, oil fill cap, and
dipstick. Be sure to allow ample time for complete
drainage.
3. Reinstall the drain plug. Make sure it is tightened
to 13.6 N·m (10 ft. lb.) torque.
4. Fill the crankcase, with new oil of the proper type,
to the "F" mark on the dipstick. Refer to "Oil Type"
on page 4. Always check the level with the dipstick
before adding more oil.
5. Reinstall the oil fill cap and tighten securely.
Reinstall dipstick.
NOTE: To prevent extensive engine wear or
damage, always maintain the proper oil
level in the crankcase. Never operate the
engine with the oil level below the "L"
mark or over the "F" mark on the dipstick.

Change Oil Filter
Replace the oil filter at least every other oil change
(every 200 hours of operation). Always use a
genuine Kohler oil filter, Part No. 12 050 01-S.
Replace the oil filter as follows:
1. Drain the oil from the engine crankcase by
removing one of the drain plugs and allowing
ample time for complete drainage.
2. Before removing the oil filter, clean the area
around the oil filter to keep dirt and debris out of
the engine. Remove the old filter. Wipe off the
surface where the oil filter mounts.
3. Place a new replacement filter in a shallow pan
with the open end up. Pour new oil of the proper
type in through the threaded center hole. Stop
pouring when the oil reaches the bottom of the
threads. Allow a minute or two for the oil to be
absorbed by the filter material.
4. Apply a thin film of clean oil to the rubber gasket
on the new filter.
5. Install the new oil filter onto the filter adapter. Turn
the oil filter clockwise until the rubber gasket
contacts the mounting surface, then tighten the
filter an additional 2/3 to 1 turn.
6. Reinstall the drain plug. Make sure it is tightened
to 13.6 N·m (10 ft. lb.) torque.
7. Fill the crankcase with new oil of the proper type
to the "F" mark on the dipstick.
