3. Place an oil drain pan under the oil drain plug,
remove the oil drain plug, and tip the machine
backward and drain the used oil in the oil drain pan

4. After draining the used oil, return the machine to the
operating position.
5. Install the oil drain plug and tighten it securely.
6. Clean around the oil fill cap (Figure 29).

of overflow. There should be very little, if any, oil left
in the bottle.(Figure 31).
Max fill: 20 oz. (0.6 l), type: automotive detergent oil
