CHECKING THE OIL

The importance of checking and maintaining the proper oil level in the crankcase cannot be overemphasized. Check the oil BEFORE EACH USE as follows:

1.Make sure the engine is stopped, level (Fig. 16) and is cool so the oil has had time to drain into the crankcase.

2.To keep dirt, grass clippings, etc. out of the engine, clean the area around the oil fill plug / dipstick before removing it.

3.Remove the oil fill plug / dipstick; wipe the oil off. Reinsert it into the crankcase. Thread the oil fill plug / dipstick into the crankcase.

4.Remove the oil fill plug / dipstick and check the oil level. The oil level should be up to the top of the dip- stick (Fig. 17).

5.If the level is low, add the oil to the top of the dipstick (Fig. 17). Always check the level with the dipstick before adding more oil.
