Kohler Courage SV710-740 Service Manual page 54

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 cool
so the oil has had time to drain into the sump.
2. Clean the area around and the under side of
the oil fill cap/dipstick before removing it. This
will help to keep dirt, grass clippings, and other
foreign matter out of the engine. See Figure 6-2.
3. Unthread and remove the oil fill cap/dipstick;
wipe off oil. Reinsert the dipstick into the oil fill
tube and rest the oil fill cap/dipstick on the oil
fill tube. Turn it counterclockwise until the oil fill
cap drops down to the lowest point of the thread
leads. Do not thread the oil fill cap onto the tube.
See Figure 6-3.
4. Remove the oil fill cap/dipstick and check oil level.
The oil level needs to be within the operating
range. See Figure 6-4. If low, add oil of the proper
type up to the full mark. If oil is above "F" or FULL
mark, drain oil to reach proper level. Reinstall the
oil fill cap/dipstick and thread until tight.
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 above the "F" or FULL mark, or below
the "L" or LOW mark on the dipstick.
Change the oil and oil filter annually or every 100
hours of operation (more frequently under severe
conditions). Refill with service class SJ oil as specified
in the ''Viscosity Grades'' table. Always use a genuine
Kohler oil filter.
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 or checking
oil. Change the oil and oil filter as follows.
1. The drain plug is located on the starter side of the
oil pan. See Figure 6-5. Clean the area around the
oil drain plug and the oil fill cap/dipstick.
2. Remove the drain plug and the oil fill cap/
dipstick.
3. Allow the oil to drain and then reinstall the drain
plug. Tighten 13.6 N·m (10 ft. lb.).
