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 5.

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. If the oil pressure
decreases below an acceptable level, the Oil Sentry™

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.
