• Do not modify the plug provided

with the tool.

• Connect this tool to a grounded

receptacle on a 15 amp ground

fault protected circuit.

Failure to observe these warnings

could result in severe injury or death.

This tool must be grounded. In the event of a malfunc-

tion or breakdown, an electrical ground provides a path

of least resistance for the electric current. This path of

least resistance is intended to reduce the risk of electric

shock.

This tool’s electric cord has a grounding conductor and

a grounding plug as shown. Do not modify the plug.

Connect the plug to a corresponding GFCI-protected

receptacle that is properly installed and grounded

in accordance with all national and local codes and

ordinances.

Do not use an adapter.

NEMA 6-15

Plug Receptacle

Do not modify the plug provided. If it will not t the

outlet, have the proper outlet installed by a qualied

electrician. Improper connection of the equipment-

grounding conductor can result in a risk of electric

shock. The conductor with insulation having an outer

surface that is green with or without yellow stripes

is the equipment-grounding conductor. If repair or

replacement of the electric cord or plug is necessary,

do not connect the equipment-grounding conductor

to a live terminal. Check with a qualied electrician or

service personnel if the grounding instructions are not

completely understood, or if in doubt as to whether the

tool is properly grounded.

Bending Conduit

Refer to the “Identication” 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"

(6mm) 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.
