Troubleshooting (cont'd)
Accuracy Adjustment
Due to variations in conduit, you may notice that the
bender consistently over- or underbends a particular size
and type of conduit. Programmed adjustments can be
made to compensate for over- and underbending
conduit. Each size and type of conduit can have a
unique adjustment ranging from plus 9 degrees to minus
9 degrees.

1. Press and hold CLEAR, and then press and hold
BEND until "Pr" is displayed.
2. Use the side switches to select the size and type of
conduit to compensate. The display shows the
current adjust value ("0" is factory default).
3. Compensate the angle:
• Press ANGLE SELECT
compensate for underbending.
• Press ANGLE SELECT
compensate for overbending.
• Press CLEAR to reset the compensation to the
factory default ("0").
4. Press BEND to save the adjust angle and exit the
adjust mode.
• The bender retains the new adjust value even if
power is turned off.

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 direction
(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
