and discharge opening. Contact with the rotating impel er can amputate 
fingers, hands, and feet.
Before starting the machine, make sure the chipper chute, feed intake, 
and cutting chamber are empty and free of all debris.
Thoroughly inspect all material to be shredded and remove any metal, 
rocks, bottles, cans, or other foreign objects which could cause personal 
injury or damage to the machine.
If the impel er strikes a foreign object or if your machine should start 
making an unusual noise or vibration, immediately shut the engine off.
