CHECK AND CHANGE ENGINE OIL
Before checking or refilling engine oil, be sure the machine is located on a stable level surface and stopped.
When check oil do not thread the oil gauge (Figure 9-1) into oil filler to check oil level. If the oil level is below the lower
level (Figure 9-1) line on the dipstick oil gauge, refill with the proper oil to the upper level (Figure 9-1)(to the neck of oil
filler).
When changing oil stop the engine, loosen the drain plug (1, Figure 9-1), reinstall the drain plug before refilling oil.
Add new oil at the oil gauge (Figure 9-1) port.

shorten the engine life.
