Safety & Operating Instructions

To Free a Jammed Flywheel
Shut down the Engine (The flywheel will continue to rotate for a while after the engine is shut off), Wait 5 minutes for the
engine to cool and all moving parts to come to a complete stop, remove spark plug wire and disconnect the negative
battery cable before moving or working on the chipper.
Tools Needed:
• Two 1/2" Wrenches
• 5/16 Wrench
• Phillips Head screwdriver
Never pry against the Scroll Weldment when removing the Deflector or Discharge Chute or at any other time. This will
cause Damage to the machine.

to the Chipper Housing with two 1/2" Wrenches and then remove the
Discharge Chute (Figure 36).
4. Check to see if the Discharge Chute or Discharge opening is
clogged. If it is, clear it with a wooden stick.
5. With a wooden stick, loosen and remove any material left in the
Chipper Housing and make sure the Flywheel turns freely with the
stick.
Reassemble:
1. Position the Discharge Chute onto the Chipper Housing and secure
with two Bolts and Locknuts using two 1/2" Wrenches.
2. Reconnect the battery negative terminal cable, the spark plug wire and
start the Chipper engine; allowing the remaining material in the Chipper
Housing to discharge.
3. If the Chipper Housing doesn’t clear and the flywheel is still
jammed, repeat above process.
Note: Be certain the Chipper Housing is clear before trying to process more
material into the Chipper Hopper.
