Setting and Adjusting the Cradle Jackscrew

CHECK THE CRADLE CLOSED-POSITION SWITCH

When the screen cradle is fully closed, the cradle front flange should be parallel with the down stroke knife block and the cradle wedges should engage the cradle freely. If this does not occur, or if the jackscrew motor continues to run when the cradle is fully closed, the jackscrew internal limit switches must be adjusted.

If the jackscrew motor continues to run beyond the closed position,

STOP THE JACKSCREW MOTOR IMMEDIATELY TO AVOID SERIOUS DAMAGE TO THE CRADLE JACKSCREW. Adjust the jackscrew closed-position limit switch.

If the cradle stops before it reaches the closed position, the jack- screw closed-position limit switch must be adjusted as described in the topic entitled Adjust the Jackscrew Closed-Position Limit Switch, which follows.

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 that no one is near the jackscrew or screen cradle during operation.

Actuate the screen cradle jackscrews by turning the selector switch to RAISE at the jackscrew console.

Hold the switch in position until the cradle approaches the closed position described previously. TO AVOID SERIOUS DAMAGE TO THE JACKSCREW, STOP THE JACKSCREW MOTOR AS SOON AS YOU OBSERVE THAT THE MOTOR DOES NOT STOP AT THE PROPER LOCATION. If necessary, adjust the cradle- closed-position limit switch as described in the topic entitled Adjust the Cradle Closed-Position Limit Switch that follows.
