the filler tube to raise the level to the full mark.
Important: Do not overfill the crankcase
with oil and run the engine; engine damage
can result.
Changing the Oil
1. Start the engine and let it run five minutes.
This warms the oil so it drains better.

all moving parts to stop before leaving the
operating position.

drain valve to allow oil to drain (Figure 38).
