Setting and Adjusting the Chamber Jackscrew
The jackscrews, which open the machine, should not operate
until the rotor is completely stopped. If you discover that the
jack- screws 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 hopper
during operation.
Actuate the cutting chamber jackscrew from the
jackscrew console by turning the CC/Hopper
(Cutting Chamber/ Hopper) switch to the RAISE
position. Hold the switch till the hopper stops or until
it passes the set point described previously in the
topic entitled Cutting Chamber Open Set point. If
necessary, reset the jackscrew open limit switch as
described in the next step.
ADJUST THE JACKSCREW OPEN-POSITION LIMIT
SWITCH
Jog the chamber open till it arrives at the set point.
Open the chamber jackscrew switch housing and
remove the keeper (I).
Turn the OPEN-POSITION NUT (2) toward the
switch (3) until the switch trips. Turn the nut an
additional half-turn toward the switch.
Replace the keeper.
Run the jackscrew to check the open-position stop.
If the stop is okay, proceed with the steps that follow.
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.
