SECTION 4-2

Adjusting or Replacing Bed Knives

(Continued from previous page)

The hydraulic cylinders or jackscrews, which open the machine, should not operate until the rotor is completely stopped. If you discover that the hydraulic cylinders or jackscrews DO operate while the rotor is still turning, immediately shut down the machine and call for maintenance to adjust it.

Wear gloves to protect against injury from the rotor or bed knives.

OPEN THE CUTTING CHAMBER INTERLOCK

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

Make sure the end of the interlock 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.

RELEASE THE CUTTING CHAMBER

FASTENERS

Turn the hold-down clamps counterclockwise to loosen them.

Swing the hold-down clamps toward you until they are disengaged from the cutting chamber housing.

SEE SECTION 6-10 PAGE 87 FOR CUTTING CHAMBER OPENING INSTRUCTIONS.
