CHECKING THE OIL LEVEL
The importance of checking and maintaining the proper
oil level in the crankcase cannot be overemphasized.
Check oil before each use:
1. Stop engine and allow oil to drain into the crankcase.
2. Place the unit on a flat, level surface to get a proper
oil level reading.
3. Keep dirt, grass clippings, etc., out of the engine.
Clean the area around the oil fill plug/dipstick before
removing it.
4. Remove the oil fill plug/dipstick and wipe off oil.
Reinsert it all the way back in.
5. Remove the oil fill plug/dipstick and check oil level.
Oil should be up to the top of the dipstick (Fig. 40).
