Adjustments

Squeeze
Proper squeeze adjustment for most 1-1/2" and 2" EMT
and IMC conduit is when the squeeze adjustment arm is
vertical (at middle hole). But variation in conduit can
result in wrinkling or side marking of conduit. If wrinkling
or excessive ovalness occurs, increase squeeze one
position (hole) counterclockwise. If loading conduit is
difficult or if excessive side marking occurs, decrease
squeeze one position (hole) clockwise.
Accuracy
If the accuracy of all sizes of conduit on one shoe is off
in the same direction, the limit switch needs to be
adjusted. Individual adjustments specific to one size and
type of conduit should be made using the Accuracy
Adjust mode (see Operation — Standard Pendant).
To adjust the limit switches, first unplug the bender.
Remove the four screws that secure the top round
guard and remove the guard to expose the two limit
switches. The top switch controls the 1-1/2" to 2" shoe.
Loosen the two screws and move it to the right side of
the bender as shown in the diagram below to prevent
overbending. The bottom switch controls the 1/2" to
1-1/4" shoe. Loosen the two screws and move it to the
left side of the bender as shown below to prevent
overbending. Move either switch the opposite direction if
the bender is underbending. Every 1/8" of switch
movement approximates 1 degree of change. Tighten
the screws and replace the guard.
