Setting and Adjusting the Cradle Jackscrew
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.
CRADLE OPEN POSITION
When fully open, the rear of the screen cradle should just make contact with the cutting chamber
support rod. If the jackscrew opens too far and the motor continues to run, IMMEDIATELY
STOP THE JACKSCREW MOTOR TO AVOID SERIOUS DAMAGE TO THE
JACKSCREW then adjust the cradle jackscrew open- position limit switch.
Alternately, if the cradle stops before it reaches the open position, the screen cradle jackscrew
open-position limit switch must be adjusted.
Avoid contact with the rotor knives, which are just above the screen. The cutting edges are very
sharp
Wear gloves to avoid injury when working in this area.
The jackscrews, which open the machine, should not operate until the rotor is completely
stopped. If you discover that the jackscrews DO operate while the rotor is still turning,
immediately shut down the machine and call for maintenance to adjust it.
Make sure no one is near the jackscrew or the cradle during operation.
