Periodic Maintenance
CLEAR THE JAM
The cutting chamber is very accessible through the screen cradles the rear hatch and
the rear hopper door.
A leather mallet and block of wood of sufficient length to keep hands away from the
path of the knives can be used if required.
Use the block of wood to exert force on the rotor, usually in the direction opposite
normal rotation.
Make sure you have secure footing on a clean floor and keep your body well braced
while prying on the rotor. Guard against loss of balance should the jammed
condition suddenly come free.
Use pliers to remove material from the cutting chamber, keep in mind that the
removal of material may cause rotation of the rotor and rotor knives.
If prying on the rotor is unsuccessful, remove the bed knife and rotor knife at the
jam. For information about bed knives, refer to Section 4, Settings and Adjustments.
Close the screen cradle per instructions in Section 6-4 entitled Screen Replacement.
Close the cutting chamber per instructions in Section 6-9 entitled Cutting Chamber
Access.
A malfunction of the machine, such as a jam, may cause undue strain or damage to any part. Do not restart the
machine after such a malfunction without checking to see whether damage was done or whether settings were
changed by the malfunction.
