Installing and Synchronizing Disks

1. IMPORTANT: Each disk must be installed 90° to the adjacent disk. If disks are not 90° to each other, damage to machine will result.

   NOTE: Disk life can be extended by moving disk to a location of opposite rotation. If this is done, the knives must be interchanged for proper cutting direction. (See INSTALLING KNIVES in this section.)

   If installing left-hand end disk, refer to REPLACING LEFT-HAND END DISK DRIVER in this section. If installing right-hand end disk, refer to REPLACING RIGHT-HAND END DISK DRIVER in this section.

   Intermediate disks next to both left and right-hand end disks are equipped with short converging drums. Converging drum is located on top of disk. Disk installation procedures are the same for all disks.
