MAINTENANCE

SECTION 6-12

Cutting Chamber Access

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.

LOWERING THE SCREEN CRADLE WITH JACKSCREWS

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 the cradle during operation.

Actuate the screen cradle jackscrew from the jackscrew console by turning the selector switch to

LOWER.

Hold the switch in position until the cradle stops. The jackscrew motor shuts down when it reaches the end of its travel.

LOWERING THE SCREEN CRADLE WITH HYDRAULICS

You will need to access the screen cradle before initial startup and for various maintenance procedures. Before accessing the screen cradle, make sure no one is near the hydraulic cylinders or hopper.

The hydraulic cylinders should not operate until the rotor is completely stopped. If the hydraulic system does operate while the rotor is still turning, immediately shut down the machine and call for maintenance to diagnose the system to find the fault.

Actuate the screen cradle hydraulic cylinders from the open/close control panel by turning the screen cradle selector switch to the “LOWER” position. Hold the switch until the cradle stops at its fully open position, and then release and return the switch to the off position.
