ADJUSTING THE SQUEEZE
When bending 1-1/4" to 2" EMT, IMC and rigid alumi-
num conduit, the roller support must be engaged so that
it contacts the conduit; the pressure against the conduit
is the “squeeze.” Typically, the squeeze adjustment arm
is vertical (at middle hole) but can be changed by
moving the position of the thumbscrew.
Due to variations in conduit, the standard adjustment
may provide too much or too little squeeze. If the
conduit develops excessive side marking when bent,
the squeeze is set too high; decrease squeeze one
position (hole) clockwise. If the conduit becomes
excessively oval or wrinkled, the squeeze is set too low;
increase squeeze position (hole) counterclockwise.
When bending 1-1/4" to 2" aluminum rigid conduit,
decrease the squeeze by three settings.

LOCATION
If the conduit develops excessive side marking when
bending in the horizontal position, the location of the
roller support assembly might need adjusting. Loosen
the left-hand and right-hand locator screws for the
Roller Support Assembly (see p. 6) to align the center-
line of the roller with the centerline of the shoe groove.
Retighten the locator screws.
