this service.
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, grass clippings, etc., out of the
engine, clean the area around the oil fill cap/
dipstick before removing it.
3. Remove the oil fill cap/dipstick; wipe oil off.
For engines with a press-on style dipstick:
Reinsert the dipstick into the tube and press onto
the tube. See Figure 6.
For engines with a thread-on style dipstick:
Reinsert the dipstick into the tube and rest the oil
fill cap on the tube. Do not thread the cap onto the
tube. See Figure 6.

page 4.) Always check the level with the dipstick
before adding more oil.

damage, always maintain the proper oil
level in the crankcase. Never operate the

mark or over the “F” mark on the dipstick.
