RELEASE THE CUTTING CHAMBER

FASTENERS

Turn the hold-down clamps counterclockwise to loosen them.

Swing the hold-down clamps toward you until they are disengaged from the cutting chamber housing

When you REVERSE the jackscrew operating direction, always ALLOW THE JACKSCREW MOTOR TO COME TO A COMPLETE STOP. Release the control switch and allow a minimum of 5 seconds before switching to the opposite operating position. If you don't allow this pause, the JACKSCREW AND OTHER COMPONENTS MAY BE SEVERELY DAMAGED.

CUTTING CHAMBER OPEN SETPOINT

At its full-open position, the cutting chamber should be open just far enough that the center of gravity of the chamber is toward the rear of the machine.

As the cutting chamber approaches its set point, the upper pivot arm moves quickly through a short distance as the hopper weight shifts to the rear. The jackscrew motor should stop just after this movement occurs.

DO NOT ALLOW THE JACKSCREW MOTOR TO RUN

BEYOND THE POINT WHERE THE CHAMBER MOTION

STOPS: THIS COULD RESULT IN SEVERE DAMAGE TO THE

JACKSCREW.

If the cutting chamber does not reach the set point or if the motor does not stop at the point described, the jackscrew limit switches must be adjusted. Confirm whether the cutting chamber operates properly as you open it in the next step.
