C Series Granulators Operation 20 of 53
4-3 Clearing a Jammed Cutting Chamber
Never attempt to free a jammed machine by placing hands on the rotor, rotor knives, or inside
the cutting chamber. Hands must be kept clear of the rotational path of the rotor knives.
Good footing on a clean floor is essential and the body should be well braced to guard against
loss of balance should the jam suddenly come free. Use the following procedure to clear a
jammed cutting chamber:
1. Disconnect and lock out power.
2. Be certain that the rotor is motionless.
3. Open the machine as instructed in Section 3-6 on page 16.
4. Use a pry bar to exert force on the rotor, usually in the direction opposite normal
rotation. A leather mallet and a block of wood of sufficient length to keep hands
away from path of knives can be used if necessary.
5. Use pliers to remove material from the cutting chamber, keeping in mind that the
removal of material may cause rotation of the rotor and rotor knives.
6. After clearing the jam, be certain that the screen and all guards and covers are
secured in place before connecting power and starting the machine.
4-4 Shut-down
Use the following procedure to properly and safely shut down the machine:
1. Stop all feeding of material.
2. Allow the granulator to run until the cutting chamber is completely empty.
3. Press the drive motor “stop” button. This shuts off the rotor drive motor.
4. After the granulator has stopped, press the airveyor stop button (if applicable) located
at the blower motor.
5. Turn the main power switch to off.
