Warning
allow the machine to come to complete stop before
inspection or servicing. The rotor is heavy and has
inertia built up that will allow the rotor to turn for some time
after the clutch has been disengaged. you can tell when
the rotor has come to a complete stop when there is no
noise or machine vibration present. you can reengage
the clutch to slow the rotor to a stop.
Do not lean over the chipper chute to push objects 5.

paddle.
Never use shovels or forks to feed brush. They can

9.
cover if the engine slows to where it may stall.
Remove the branch and rotate it before reinserting it
10.
into the chute if the chipper jams.
