PUNCH MOUNTING PLATE (Preliminary)
Requirement
The punch mechanism mounting screw, beneath punch block, and mounting screw at lower
edge of punch mechanism backplate should be located centrally within their respective
mounting holes.
Note: The mounting holes are oversize to facilitate use of punch mechanism on the
typing reperforator.
To Adjust
Remove mounting screw at the lower edge of punch mechanism backplate. With the two
remaining backplate mounting screws and mounting bracket screw friction tight, position
punch mechanism so that the tapped hole of the frame is centrally located (as gauged by
eye) within large body hole of punch mechanism backplate. Tighten the two backplate
mounting screws and recheck to see that requirement is met. Replace and tighten the
lower backplate mounting screw. Tighten the bracket mounting screw.
