Check Oil Level
The importance of checking and maintaining the
proper oil level in the crankcase cannot be
overemphasized. Check oil BEFORE EACH USE as
follows:
1. Make sure the engine is stopped, level, and is cool
so the oil has had time to drain into the sump.
2. To keep dirt, debris, etc., out of the engine, clean
the area around the dipstick before removing it.
3. Remove the dipstick; wipe oil off. Reinsert the
dipstick into the tube and press all the way
down. See Figure 6.
Figure 6. Checking Oil Level.
4. Pull the dipstick out and check the oil level.
The oil level should be up to, but not over, the “F”
mark on the dipstick. See Figure 7.
Figure 7. Oil Level Dipstick.
5. If the level is low, add oil of the proper type, up 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.

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.
Oil Sentry
™
Some engines are equipped with an optional Oil
Sentry
™
oil pressure switch monitor. 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 Filter
Change the oil and oil filter every 200 hours or
annually, whichever comes first (more often under
severe conditions). Refill with service class SG, SH, SJ
or higher oil, as specified in the Viscosity Grades table
(Figure 3) on page 4. Always use a genuine Kohler oil
filter. Use chart below to determine part number to
order.
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, or changing the oil.
Change the oil and oil filter as follows (see Figure 8):
1. To keep dirt, debris, etc., out of the engine, clean
the area around the oil fill cap before removing it.
2. Remove one of the oil drain plugs and the oil fill
cap. Be sure to allow ample time for complete
drainage.
3. 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 and wipe off the
filter adapter with a clean cloth.
4. Reinstall the drain plug. Make sure it is tightened
to 13.6 N·m (10 ft. lb.) torque.
5. 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.
