ALWAYS inspect the bender before operating. Replace any damaged,
missing or worn parts.

WEAR approved safety glasses when using the bender.

Bender MUST be used on a firm, flat surface.
DO NOT use on an inclined surface.

ALWAYS keep the path of the bending conduit clear of obstructions.

ONLY use the bender for its intended purpose. Only use the bender to
bend the specified types and sizes of conduit or pipe.

DO NOT allow the rolling shoe carriage to make contact with the
elevating shoe carriage.

ONLY roll on a firm, flat surface.

NEVER use an impact driver to operate the offset bender. Using an
impact driver could damage the gearbox and other components.

(1/2–13 × 8")

1. Unfold the front leg and secure with the

2. Unfold the rear leg and secure with the
bolt, washer and locknut provided.

3. Insert the gauge rod as shown and
secure with the thumb screw.

OPERATING INSTRUCTIONS

Zero line on

OFFSET BENDS

1. Determine the height and angle for the desired offset

2. Refer to the rolling shoe starting position chart and use the multipler
calculation to determine the starting arrow position of the rolling shoe.
As an example, for a 45° bend, the multiplier is 1.41. To make a 10" high
offset bend, multiply 10" × 1.41 = 14.1". Place the arrow on the rolling
shoe at the 14.1" mark on the horizontal scale.

3. Using a battery powered drill (recommended drill –

1/2" variable speed cordless drill with a minimum
18 Volts), connect to the hex drive shaft with
the 3/8" hex bit provided. Align the
zero line on the vertical
scale with the vertical scale

4. With the conduit support
block lowered, the rolling
carriage block closed and
secured and the conduit
hold down open, slide the conduit over the conduit support block and
through the correct groove on the rolling and elevating shoes. (See chart
below for the correct groove size). Continue to slide the conduit past the
elevating shoe until the desired amount of conduit extends past the shoe.
The length of conduit that extends past the edge of the elevating shoe
will be the straight portion of the conduit that extends past the offset.

NOTE: All shoes are marked with a line indicating the center of the bend.

NOTE: Check the arrow on the rolling shoe carriage to be sure it has not

moved during the bending set up process.

6. Using the Springback Chart for Vertical Scale (see chart below), determine
the height to raise the elevating shoe. As an example, for a 45° bend, add
an additional 5% to the desired offset height. To make a 10", 45° offset,
you would add an additional 5%, which is ½", for a total of 10 ½".

calculated in step 6. The
rolling shoe will move as
the elevating shoe rises and
create the second bend.

8. To remove the bent conduit,
slightly lower the elevating
shoe to release the tension
on the conduit. Then, pull
the quick release pin and
raise the rolling carriage
block to the open position.
Next, pull the pawl release
and raise the conduit hold
down. Remove the conduit.

NOTE: Be sure to lower the conduit support block and close and secure the
rolling carriage block before setting up the next bend.

NOTE: If the end of the conduit that extends past the conduit hold down is
too high, the conduit hold down screw should be lowered. If it is too
low, the conduit hold down screw should be raised.

OPERATING INSTRUCTIONS

Elevating shoe

Saddle Bend

1. Complete an offset bend as previous instructed. Pull the pawl release and
raise the conduit hold down. Next, lower the elevating shoe to the zero (Ø)
position. Rotate the conduit 180° degrees to ensure your two offsets will
be in perfect alignment.

2. Slide the desired length of conduit through the elevating shoe to create
the straight length between the offsets.

3. Return the rolling shoe carriage to the starting position of the offset,
lower the conduit hold down and tighten the screw against the conduit.
Then, raise the elevating shoe to the calculated offset height including the
springback.

4. To remove the bent conduit, slightly lower the elevating shoe to release
the tension on the conduit. Then, pull the quick release pin and raise the
rolling carriage block to the open position. Next, pull the pawl release and
raise the conduit hold down. Remove the conduit.

Matching Existing Offsets

1. You can match existing offsets without knowing the degree of the bend.
First, measure the center distance on the bends of the existing offset. Set
the arrow on the rolling shoe carriage at that number on the horizontal
scale.

2. To determine the vertical scale calculation, measure the height of the
existing offset. Next, check the springback chart and add the springback
amount to this height.

Gauge rod indicator

Multiple Offset Bends
To easily repeat offsets, the Model 754

is equipped with a gauge rod.

carriage

1. To set the gauge rod, raise the
elevating shoe to the calculated
height for the first bend.

2. Next, loosen the thumb screw and
raise the gauge rod until the gauge
rod indicator just touches the top of
the elevating shoe carriage
(see drawing). Retighten thumb
screw.

3. Gauge rod is now set for repeat
bends.

OPERATING INSTRUCTIONS

SHOE ALIGNMENT
The shoes on every Model 754 are set and tested for alignment prior to

shipping. However, if they ever become misaligned, use the following
procedure to realign.

Front Bend — If the front bend has a ”dog,” the elevating shoe
will need to aligned.

Rear Bend — If the rear bend has a ”dog,” the rolling shoe will
need to be aligned.

Loosen the bolts that hold the shoe in question and use a straight piece of
conduit to realign the shoe. Re-tighten the bolts.

OPTIONAL SHOE GROUPS

Optional shoe sets to bend mutiple pieces of the same size conduit are
available.

• Part #754-1/2 is the complete set of shoes and accessories to bend 4 pieces
of ½" EMT at the same time.

• Part #754-3/4 is the complete set of shoes and accessories to bend 2 pieces
of 3/4" EMT or 1/2" Rigid at the same time.

MAINTENANCE

To ensure smooth operation, apply a liberal amount of multipurpose grease
to the gear rack monthly.
