•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.
