Check Oil Level; Oil Cooler - Kohler Command CH18 Owner's Manual

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.
4.
Remove the dipstick and check the oil level.
The oil level should be up to, but not over, the " F
mark on the dipstick. See Figure
7.

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 5.) 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 SentryTM
Some engines are equipped with an optional Oil
SentryTM oil pressure switch. If the oil pressure
decreases below an acceptable level, the Oil SentryTM
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 US€ and is maintained up to the " F
mark on the dipstick. This includes engines
equipped with Oil SentryTM.
Change Oil and Filter, Service Oil Cooler
Change Oil
Change oil after every 100 hours of operation (more
frequently under severe conditions). Refill with service
class SG, SH, SJ or higher oil as specified in the
"Viscosity Grades" table (Figure 3) on page 5.
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 Figures 8 and 9):
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 5. 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.
