5.1 Clamp Foot Pad or Cylinder Replacement
5.1.1 TO REPLACE THE CLAMP FOOT PAD:
1. The Clamp Foot Pad is not attached by adhesive. While the Clamp Foot is still attached
to the machine, use a flat blade screwdriver to remove the old Pad by carefully levering it
out of its seat.
2. The rim of the new Pad must be bent and popped into place. Insert an edge of the new
pad into the Clamp Foot and use a flat blade screwdriver to wedge the rest of the Foot
Pad into the Clamp Foot.
5.1.2 TO REPLACE THE CLAMP FOOT OR CLAMP CYLINDER:
1. Connect 85 PSI directly to the Clamp Cylinder to manually actuate it.
2. With the shaft fully extended, hold the shaft stationary with a ½”
wrench and loosen the
jamb nut with a ¾” wrench. Continue holding the shaft stationary with the ½” wrench and
use large slip-joint pliers to turn the Clamp Foot and break it free of thread lock com-
pound. See Fig 2.
