”, 1 1 ⁄

” and 2” Conduit
NOTE: All operations referring to “toward the operator”
are viewed from the lifting handle end of the bender
frame.
1. Bending 1 1 ⁄ 4 " through 2" requires using one of the
three sets of nylon rollers and one of the grooves on
the lower half of the bending shoe.
2. Move the roller housing against the frame stop
(figure 10). The upper urethane roller must be on the
outside (toward frame handle) of the roller housing
(figure 6). If it’s not, pull the ring pin. Lift
the roller support arm, swing it over the roller
housing, lower the handle into the bracket and insert
the ring pin.
To avoid damage to the bending shoe, always place
the roller housing against the frame stop, prior to
activating the bending shoe.
3. Check the bending shoe to be sure the correct
grooves for the conduit being bent are facing toward
the operator. If the shoe must be rotated, hold the
pendant control toggle switch in “Return” and press
the override button until the zero light goes out. The
shoe will rotate 180° then stop in the load position
(figure 7).
4. When bending 1 1 ⁄
4
" - 2"
conduit, position roller
housing and upper arm.
Then push the conduit
between the shoe groove
and the 2" nylon rollers
until the bend mark on the
conduit is in line with the
outside edge of the
clamp jaw.
5. Grasp the upper urethane
roller and move the support
arm counterclockwise until
it contacts the roller housing. The two nylon rollers
should have moved against the conduit and should
firmly hold the conduit in the shoe (figure 8).
6. Each time a different size and type of conduit is
being bent, three facts must be determined and set
into the bender shoe control system. The required
settings are: conduit size, material and desired bend
angle. Prior to setting, be sure the desired size
indicator scale is toward the operator and the
correct shoe grooves are also toward the operator.
a. Lift the angle knob locking handle to release the
angle set knob and angle indicating disc. Use
the two small knobs to rotate the angle disc,
clockwise (figure 9).
b. Set the bender for specific conduit size by
turning the angle disc until the red line and
pointer are on an outer size indicator mark
which matches the size conduit being bent
(figure 9). Be sure the correct size indicator is
being used (EMT, lMC, or Rigid).
c. Move the bend angle knob (figure 9) until the
flat edge of the pointer is on the line indicating
the exact degree of bend desired. Lower the
center handle to lock the pointer and scale
and to prevent inadvertent movement
during bending.
