3-6 Accessing the Cutting Chamber
You will need to access the cutting chamber before initial startup and for various
maintenance procedures. Before accessing the cutting chamber, make sure no one is near the
jackscrew or hopper. The jackscrews should not operate until the rotor is completely stopped.
If the jackscrews do operated while the rotor is still turning, immediately shut down the
machine and call for maintenance to adjust it.
Use the following procedure to access the cutting chamber:
1. Turn the main power off, remove the line fuses, and tag the machine as out of
service.
2. Unscrew the cutting chamber interlock actuator screw with a box wrench or ratchet
wrench. Make sure the end of the interlock actuator screw is visible and clear of any
contact. When disengaged, the interlock opens the electrical control circuit to the
motor and prevents the machine from running.
3. Turn the cutting chamber hold-down fasteners counterclockwise to remove them, and
place them on the lip of the upper cutting chamber.
4. Start the cutting chamber jackscrew from the jackscrew control panel by turning the
CC/Hopper switch to the “Raise” position and pressing the button in the center of the
switch. Hold the button until the hopper stops, and then release the button and return
the switch to the off position.
Caution! Allow the jackscrew motor to come to a complete stop, and wait at least 5
seconds before reversing the motor. The jackscrew and other components
may be severely damaged if the jackscrew motor is reversed before it has
completely stopped.
5. Position the rotor so that a blade is at the top center, and lock the rotor by inserting
the rotor locking pin into the hole on the right side bearing housing.
Note: Apply light pressure against the pin while turning the rotor toward you
approximately 10 degrees. The pin will drop into the hole when it is properly
aligned.
