Changing Oil
To drain oil from the engine's crankcase, proceed as
follows:
Run the engine for a few minutes to allow the oil to
warm up. Warm oil flows more easily and will carry
away more impurities when draining oil.
Position the chipper shredder on level surface and
place an appropriate receptacle with a capacity of
at least one quart beneath the oil drain tube. See
Figure 16.
