Maintenance Schedule
These required maintenance procedures should be performed at the frequency stated in the table. They should
also be included as part of any seasonal tune-up.
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 6.
Figure 6. 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.
