Changing Shoes
1. Disconnect the bender from the power source.
2. Lock the bender head in the vertical bending
position (see Pivoting the Bender Head in the
Transportation and Setup section of this manual).
3. See the 1/2" to 1-1/4" Side Exploded View or the
1-1/2" to 2" Side Exploded View. Use heavy-duty
retaining ring pliers to remove the retaining ring (26)
that secures the shoe.

these holes.
5. Mount the replacement shoe onto the spindle. Align
the slot in the shoe bore with the screw head on the
spindle. Push the shoe onto the spindle until the
drive lugs are fully engaged in the drive lug holes.
Replace the retaining ring.

Setting Roller Support Limit Switch
The switch is activated by the main outer roller support
arm, in the retracted position. Retract the switch from
the maximum switch travel by pivoting the switch in
its mounting holes and rotating it clockwise in its
mounting slot.
Set the squeeze adjustment at the maximum clockwise
position. Move the switch in a counterclockwise direc-
tion (with a 0.030" feeler gage between the roller arm
and the body). When the roller, arm, gage, and switch
body are in contact, tighten the mounting screws.
The switch lockout circuit is normally closed. Attach
alligator clips to the common and normally closed
switch terminals to check switch trip operation.
Do not insert meter probes into the Molex
