operation. Change the oil while the engine is still warm. The oil will
flow freely and carry away more impurities.

on the unit and clean
up any oil that may

the oil according to
Federal, State and local
regulations.

measures approximately 3.04 ounces (90 ml) (Fig. 30). Check
the level, See Checking the Oil Level. If the level is low, add a
small amount of oil and recheck. Do not overfill (Fig. 30).
