Wear proper apparel. Do not wear loose clothing,
gloves, neckties, rings, bracelets, or other jewelry
which may get caught in moving parts. Nonslip foot-
wear is recommended. Wear protective hair covering
to contain long hair.
Failure to observe this precaution may result in injury
or property damage.
Refer to the “Identication” section of this manual.
1. Turn on the main power switch (2).
2. Use the BEND or UNLOAD button to
orient the shoe so that the hooks of the
conduit type to be bent are around the
7o’clock (approximately –5°) position.
(Silver hooks are for EMT; green hooks are
for IMC and rigid.)
The bender automatically stops at the load
position (approximately –5°). To continue
past the load position, release the BEND
or UNLOAD button, and then repress the
BEND or UNLOAD button as needed.
The bender actively prevents operation at certain
angles while the roller supports are up. This is done
to prevent the shoe hooks from damaging the roller
supports. When the roller supports are up and the
hooks are close to or within the roller supports, the
pendant will blink “UP” twice. When the pendant
blinks “UP”, the bender can often be moved in the
opposite direction by pressing BEND or UNLOAD.
If the bender will not move in any direction and con-
tinues to blink “UP”, then the roller supports must
be fully retracted before the bender will move.
3. Load the conduit so that the bending mark is
aligned with the front edge of the hook.
4. Bend the conduit.
a. For 1/2" and 3/4" EMT, IMC, or rigid conduit,
raise the rollers from the retracted position to the
upright position, as shown below.
Squeeze Rollers Retracted Squeeze Rollers Engaged
b. For 1-1/4", 1-1/2", and 2" EMT or IMC conduit,
use the roller engagement handle (16) to raise
the rollers from the retracted position to the
upright (engaged) position, as shown below.
Squeeze Rollers Retracted Squeeze Rollers Engaged
Press BEND while applying pressure to the roller
engagement handle until the rollers hit their stop.
Note: Lifting the tail of a long stick of conduit will

Note: To retract the rollers without bending after the
cam locks them in place, pump the lever below the
2" split roller several times. If this does not release
the cam, lift the tail of the conduit while pumping the
release lever. Otherwise, advance the shoe forward
just enough for the cam to release, and then unload.
Squeeze Roller
Release Lever
c. For all other conduit, press BEND while making
sure the bend mark stays at the front of the hook
until the conduit contacts the tail roller.
5. Continue to press BEND until the pendant display is
close to the desired reading. Use JOG to complete
the bend. JOG will advance the shoe about 1/2"
and help prevent accidental overbending. The dis-
played angle in the pendant is the shoe rotation and
does not include springback in the conduit. Refer to
the Bend Angle Chart in the “Bending Instructions”
section of this manual for display readings for
common bend angles.
6. Press UNLOAD to free the conduit.
7. Twist the conduit to release it from the hook and
remove it from the shoe.
Programmed Bending
If an angle is preset into memory, the bender will auto-
matically stop at that angle.
Note: “Angle” represents the angle of the shoe and
does not include conduit springback. The digital display
chart shown in this manual and on the decal on the
bender provides display readings for common bend
angles.
1. Select the angle by using the ANGLE SELECTp
or ANGLE SELECTqbutton on the pendant to
change the programmed angle. A single press
changes the angle by 1°. Holding down an
ANGLESELECT key changes the angle rapidly in
5° increments. Pressing CLEAR resets the pro-
grammed angle back to 0°.
This programmed angle stays in the memory until
CLEAR is pressed, a new angle is selected, or the
power is turned off. The programmed angle remains
in the pendant display for about 2 seconds and then
reverts to the actual shoe angle.
2. Press BEND until the bender stops. The bender
may slow down before reaching the selected
angle. This is normal. When the bender stops at
the programmed bend, the pendant display blinks
twice with the programmed angle. To continue
a bend, reset the programmed angle with the
CLEAR button, or increase the programmed angle
to be greater than the actual shoe angle with the
ANGLESELECTpbutton.

Operation (cont’d)
Squeeze Adjustment
Squeeze is factory set and should not normally need to
be adjusted.
When bending 1-1/4", 1-1/2", or 2" EMT or IMC, the
amount of squeeze applied to the conduit can be
adjusted to compensate for conduit variations. The
squeeze is set properly if the support shaft does not
contact the support plates while bending EMT, as
shown by the shaded parts below. The shaft should
not be more than approximately 1/4" (6 mm) above the
lower at surface.
Squeeze can be checked by loading EMT conduit
and advancing the shoe until conduit starts to bend.
If support shafts touch plates or are more than 1/4"
(6mm) from plates, unload conduit and adjust squeeze
as described.
• If shaft is touching, increase squeeze.
• If shaft is farther than 1/4" (6 mm), decrease squeeze.
1/4" (6 mm) max. gap between
shaft and top of side plates
To adjust the squeeze:
1. Unplug the bender.
2. Remove screw (refer to illustration below).
3. Rotate the squeeze adjuster:
• If the shaft is contacting the support plates,
increase the squeeze by rotating the squeeze
adjuster clockwise.
• If the shaft is too high above the support plates,
decrease the squeeze by rotating the squeeze
adjuster counterclockwise.

q= angle of bend
r = the centerline bending radius of the bending shoe
kick — single bend of less than 90°
leg length — the distance from the end of a straight section
of conduit or pipe to the bend; measured from the end to the
outside edge of the conduit or pipe.
offset bend — two opposite bends with the same degree of
bend; used to avoid an obstruction.
offset height — the distance between the two legs of
an offset bend, measured perpendicular to the two legs; also
called amount of offset and depth of offset.
rise — the distance from the end of a straight section of
conduit or pipe to the bend; measured from the end to the
center line of the conduit or pipe. Also called stub or
stub-up.
saddle — a three-bend or four-bend combination; used
to avoid an obstruction.
shrink — the amount of conduit “lost” when laying out an
offset bend working toward an obstruction.
springback — the amount, measured in degrees, that a
conduit or pipe tends to straighten after being bent.

90° STUBS
1. Measure the length of the required stub.
2. Refer to the Minimum Stub Length formula on the
Deduct Table. The required stub must be equal to or
longer than the Minimum Stub Length.
3. Measure and mark the stub length on the conduit.
This is Mark 1. Subtract the Deduct from this mark
and make a new mark. This is Mark 2.
4. Align Mark 2 with the front edge of the hook and
bend the conduit.
Note: The shoe bends to 90° maximum.
Note: When the operator presses UNLOAD, the conduit
may spring back a few degrees. Compensate by over-
bending as shown in the Bend Angle Chart below.

Offsets
1. Measure the height and length of the obstruction.
Select the angle to be used.
2. Refer to the Offset Table. The height of the obstruc-
tion must be equal to or greater than the minimum
offset.
3. Refer to the X Table to nd the X dimension. Refer
to the Offset Table to nd the center-to-center
distance.
Note: If the center-to-center distance is not shown,
calculate it by using the multipliers shown in the
Offset Table.
4. Mark the conduit as shown.
5. Insert the conduit into the bender. Align Mark 1 with
the front edge of the hook and bend the conduit.
6. Align Mark 2 with the front edge of the hook.
Without removing the conduit from the bender,
rotate the conduit 180°. Make the second bend.

OFFSETS
An offset is used to route the conduit around an
obstruction. To make an offset, two equal bends are
required. The distance between the two bends is the
center-to-center distance.
When working past an obstruction, it is necessary to
determine the location of the rst bend. The center-to-
center distance is then used to determine the location of
the second bend. When working toward an obstruction,
it is necessary to determine the location of the second
bend. The center-to-center distance is then used to
determine the location of the rst bend.
Working Past an Obstruction
1. Select the size and type of conduit. Measure the
height of the obstruction and the distance labeled
LENGTH. Determine the angle to be used.
2. Find the table that corresponds to the size and type
of conduit selected in Step 1.
3. To the right of the size and type of conduit, nd the
dimension labeled X. Subtract X from LENGTH.
Place the rst bending mark this distance from the
end of the conduit.
4. Under the column labeled ANGLE, nd the appro-
priate angle. Find the row labeled L1. In the row at
the top of the page, nd the height (H) of the offset.
The number shown at the intersection of row L1 and
column H is L1. Place the second bending mark L1
inches from the rst bending mark.
5. Bend the conduit.
