Operation
(cont’d)
USING ROLLER SUPPORT UNITS
Use the roller support units to squeeze the conduit as it
is bent.
Using the 1/2" to 1-1/4" Roller Support Unit
Pivot this roller support upward and into place when
bending all types of 1/2" to 1-1/4" conduit. Pivot the
roller support down for easier loading and unloading.
Using the 1-1/2" to 2" Roller Support Unit
Engage this roller support when bending 1-1/2" to 2"
EMT, IMC, and rigid aluminum conduit:
1. Load the conduit.
2. While momentarily pressing BEND, move the roller
engagement handle up and to the left. The rollers
will move up and squeeze the conduit against the
shoe. Apply enough force so that the roller support
unit contacts the stops before the conduit starts to
bend.
Note: If it is difficult to engage the rollers completely,
the squeeze is probably set too high. See Adjusting the
Squeeze in this section of the manual.
ADJUSTING THE SQUEEZE
When bending 1-1/2" to 2" EMT, IMC, and rigid alumi-
num conduit, the roller support must be engaged so that
the roller supports the conduit; the pressure against the
conduit is the “squeeze”. Setting the squeeze adjust-
ment arm to the vertical position (middle hole) provides
the necessary amount of squeeze for most 1-1/2" to 2"
EMT and IMC conduit.
Due to variations in conduit, the standard adjustment
may provide too much or too little squeeze.
If the conduit is difficult to load or develops excessive
side marking when bent, the squeeze is set too high.
If the conduit becomes excessively oval or wrinkled,
the squeeze is set too low.
To change the amount of squeeze:
1. Loosen the adjustment arm screw.
2. Rotate the adjustment arm one position counter-
clockwise to INCREASE the squeeze or one posi-
tion clockwise to DECREASE the squeeze.
Note: Decrease the squeeze by three settings when
bending rigid aluminum conduit.
3. Align the adjustment arm with one of the holes and
tighten the screw.
Changing the squeeze may affect the bending accuracy.
If the pointers are inaccurate after changing the
squeeze, see Pointer Accuracy under Maintenance.
