GROUNDING INSTRUCTIONS
This bender is intended for use on a circuit that has a receptacle that looks like
the one illustrated below. The bender has a grounding plug that looks like the
plug illustrated below.
In the event of a malfunction or breakdown, grounding provides a path of least
resistance for electric current to reduce the risk of electric shock. The bender is
equipped with an electric cord having an equipment grounding conductor and a
grounding plug. Only connect the bender to a 20 amp GFCI protected receptacle
which is properly installed and grounded to meet all applicable electrical codes.
DO NOT use an adapter.
DO NOT modify the plug provided. If it will not fit the receptacle, have the
proper receptacle installed by a qualified electrician.
Improper connection of the equipment grounding conductor can result in 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 qualified electrician or service personnel if the grounding
instructions are not completely understood, or if in doubt as to whether
the bender is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding plugs and
3-pole receptacles that accept the bender’s plug.
Repair or replace damaged or worn cord immediately.

SHOE SET-UP
The 747 Omni Bender is equipped with everything needed to bend 1⁄2" thru
2" EMT, IMC, Rigid steel and Rigid aluminum conduit. Also, 40 mil PVC
coated Rigid conduit can be bent with optional shoe and roller support.
1. Choose the shoe for the size conduit you will be bending. The 747 Omni
Bender has a four groove bending shoe for 1⁄2" thru 11⁄4" EMT, IMC and
Rigid conduit. The two groove shoe bends 11⁄2" and 2" EMT, IMC and
Rigid conduit.
If your chosen shoe is not on the front
nose of the bender, you must remove both
shoes and switch their positions.
NOTE: Both shoes are retained by spring
loaded pawls. Press down on the
spring loaded retainer pawls to
remove both shoes (see photo at
right).
2. Place the shoe you are not using onto the
spare shoe tube located on the rear of the bender.
3. Next, you must rotate the bend degree pointer for the size shoe you have
chosen to the minus ten degree (-10˚) position. To do this set the switch
on the pendant to the "UNLOAD" position. Then press the "JOG" button
and rotate the bend degree pointer that matches the size shoe you have
chosen until it is at the minus ten degree (-10˚) position. (See photos
below).
NOTE: Because the pointer will only activate the Bend Angle Limit Switch
and Stop Switch in the clockwise direction, be sure to rotate the
pointer in the counter-clockwise direction when positioning the
pointer.

SHOE SET-UP – CONTINUED
The drive sprocket on the 747 Omni Bender has 2 large holes and 2 small
holes to accept the bending shoe drive studs. Therefore, each shoe will
mount in 2 positions. When mounting the shoes, align the large drive
studs with the large holes and the small studs with the small holes. (See
drawing below).
4. Place the shoe on the bender so that the hook for the type conduit to
be bent is at approximately the 6 o'clock position.
Note that the bending shoe hooks are color coded. The blue hooks are
for Rigid and IMC conduit and the silver hooks are for EMT conduit.
NOTE: The bending shoe should be
pushed completely onto the
nose of the bender to allow the
retaining pawl to secure the
bending shoe.
NOTE: Photo shows the 1 1⁄2" to 2"
shoe positioned to bend Rigid
or IMC Conduit.

BEND ANGLE LIMIT SWITCH AND STOP SWITCH
Bend Angle
Limit Switch
The 747 Omni®Bender has an adjustable bend angle limit switch for easy
repeat bends. The bend angle limit switch will adjust from approximately
five degrees (5°) to one hundred and five degrees (105°).
1. To set the Bend Angle Limit Switch, slide to the desired degree of bend.
(See photo below).
NOTE: The pointers will only activate the bend angle limit switch when
operating in the clockwise (bending) direction.
DO NOT bend over 105°. Doing so will cause the hook on
the other side of the shoe to collide with the conduit.

2. When the pointer reaches the Bend Angle Limit Switch, the bender
will stop.
3. If you do not want to use the Bend Angle Limit Switch, before
bending, slide it clockwise as far as possible (about 105°).
4. An internal stop switch is provided to help avoid damage to the shoe
hook and roller assembly.
Pointer
NOTE: The stop switch
noted in #4 above is located
behind the face plate and
main sprocket of the bender
and is designed to stop the
bender shoe from turning
if the pointer does not
activate the Bend Angle
Limit Switch, thus avoiding
damage to the shoe hook
and roller assembly.
NOTE: If the stop switch activates and
stops the bending shoe from turning in
the bend direction, change the Bend/
Unload switch to the Unload position and
press jog button to turn the shoe in the

SUPPORT ROLLER RETURN SPRING
In addition to the stop switch that is provided to help avoid damage to the
shoe hook and built-in support roller assembly, the 747 Omni™Bender has
a return spring installed on the built-in support roller assembly (See Figure
A1). The return spring is designed to return the support rollers to the down
position (See Figure A2) after a bend is completed. Returning the support
roller assembly to the down position after a bend will help prevent the bender
shoe hooks from contacting the rollers when the rollers are not in use.
