Bending Conduit
Refer to the “Identication” section of this manual.
1. Plug the bender into a grounded 15 amp outlet.
2. Plug the pendant switch into the pendant receptacle
(6).
3. Turn on the main power switch (7).
4. Verify the shoe orientation.
If the pendant display shows approximately
the same degree as the pointer on the shoe,
the shoe position is correct. If not, rotate the
shoe’s engagement points in the sprocket
90° by hand or zero the pendant display. The
shoe units in the 12580 and 12581 bending
groups have drive studs that will align in only
one position with the holes in the sprocket.
Re-zero the pendant display to align the desired
shoe pointer with zero on the bender decal.
5. Press BEND or UNLOAD on the pendant until
the shoe is 5° to 10° before the starting point (0°)
(approx. –5° on 555DX pendant).
6. Load the conduit so that the bending mark is
aligned with the front edge of the hook.
7. Determine the angle to stop at to achieve the
desired bend angle from the bending decal or tables
in this manual.
8. Bend the conduit.
a. For 1-1/2" and 2" EMT or IMC conduit, use the
roller engagement arm (4) to raise the squeeze
rollers and position them so that both rollers
make contact with the conduit. Note that the
engagement arm can be placed in either of two
positions to facilitate hand or foot actuation.
Press BEND while applying pressure to the
engagement arm until the rollers hit their stop.

b. 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.
9. Continue to press BEND until reaching the desired
bend angle.9. Continue to press BEND until
reaching the desired bend angle.
• Use JOG to sneak up on an angle. JOG will
advance the shoe about 1/2°.
• Use BEND to sneak up on an angle.
Note: The angles displayed on the bending decal
and the pendant may not always be in sync due
to shoe casting variations, although they will be
consistent.
10. Press UNLOAD to free the conduit.
11. Twist the conduit to release it from the hook and
remove it from the shoe.

Operation (cont’d)
Squeeze Adjustment
Squeeze is factory set and should not normally need to
be adjusted.
When bending 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 conduit does not contact the roller on
the tail roller support (10) while bending EMT. Also, the
conduit should not be more than approximately 1/4"
(6mm) above the tail roller.
1/4" (6 mm) max.
To adjust the squeeze:
1. Unplug the bender.
2. Remove screw (refer to gure below).
3. Rotate the squeeze adjuster:
• If the conduit is contacting the tail roller, increase
the squeeze by rotating the squeeze adjuster
clockwise.
• If the conduit is more than 1/4" (6 mm) above
the roller, decrease the squeeze by rotating the
squeeze adjuster counterclockwise.

Illustrated Bending Glossary
back-to-back bend — any U-shaped bend formed by two
parallel 90° bends with a straight section of conduit or pipe
between the bends.
center-to-center distance — the distance between the
successive bends that make up an offset or a three-bend
saddle.
developed length — the actual length of pipe that will be
bent; refer to distance “d” in the illustration at left.
gain — the difference between the straight-line distance
(a + a) and the shorter radial distance, (d) where:
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.

Bending Instructions
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.
Notes:
When the operator presses UNLOAD, the conduit may
spring back a few degrees. Compensate by overbending
as shown in the Scale Reading Tables.
The rigid shoe can make a 180° bend in one shot. All
other shoes bend to 90° maximum.

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.
