Setting and Adjusting the Cradle Jackscrew

OVERVIEW

Proper adjustment of the two machine-mounted jackscrews is important to performance and safety. Improper settings can result in premature failure of the jackscrews.

To avoid severe damage to the screen cradle jackscrew, BE PREPARED TO SHUT IT DOWN IMMEDIATELY WHEN THE CRADLE IS MOTIONLESS FOR ANY REASON WHILE THE MOTOR IS RUNNING. This condition can occur when the screen cradle jams on debris or when the cradle reaches the end of its stroke, whether on the opened or closed end of the stroke (if the limit switches are not properly adjusted).

This procedure describes how to check and make adjustments to the screen cradle jackscrew limit switches.

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.

OPEN THE SCREEN CRADLE INTERLOCK

Disengage the interlock actuator screw with a box wrench or ratchet wrench.

Make sure the end of the 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.

RETRACT THE SCREEN CRADLE RETAINERS

Turn the screen cradle retainer knobs clockwise until they stop. (This retracts the support wedges from beneath the screen cradle.)

When the wedges are fully retracted, rods extend so that their ends are flush with the surface of each of the retaining knob mounting plates.
