Figure 6. Oil Level Dipstick.
5. If the level is low, add oil of the proper type, up to
the FULL 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 ADD
mark or over the FULL mark on the
dipstick.
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
FULL 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 2) on page 4. Always use a genuine
Kohler oil filter, Part No.
52 050 02-S
.
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 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 and the oil fill
cap/dipstick. 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.
6. Put a drop of oil on your fingertip and wipe it on
the rubber gasket of the new oil filter.
7. Install the new oil filter to the filter adapter. Hand
tighten the filter clockwise until the rubber gasket
contacts the adapter, then tighten the filter an
additional
2/3 to 1 turn
.
8. Fill the crankcase with new oil of the proper type,
to the FULL mark on the dipstick. Refer to Oil
Type and Check Oil Level on pages 4 and 8.
Always check the level with the dipstick before
adding more oil.
9. Reinstall the oil fill cap/dipstick and tighten
securely by turning to the right.
