11.7.1. Replace Proof Test Grip
Remove the 4 flat head screws on top of the proof test mandrel and lift off the flanged top. Depress the mandrel
clamp button and remove the rubber grip. Install a new grip making sure that the grip is uniformly positioned
around the mandrel and seated below the bottom flange. Replace the top flange and 4 flat head screws. Make
sure that the mandrel clamp operates freely and that the rubber grip does not rub against the clamping arm. After
replacing the proof test grips, a calibration check should be performed.
