IMPORTANT SAFETY INSTRUCTIONS
To reduce the risk of injury, read and understand this instruction sheet.
WARNING
Failure to understand how to safety operate this tool could result in an ac-
cident causing serious injury.
Always inspect the bender for wear or damage before each use. A worn or damaged tool may
fail, resulting in injury or property damage.
Use this tool only for its intended use. Other use may result in injury.
Keep proper footing and balance at all times. This enables better control of the tool in unexpected
situations.
Always wear eye protection. Protective equipment used for appropriate conditions will reduce
personal injuries.
READ AND SAVE THESE INSTRUCTIONS
MILWAUKEE conduit benders are used to bend 1/2" through 1" EMT and 1/2" through 3/4" rigid
conduit.

FUNCTIONAL DESCRIPTION

1. Center of Saddle Bend Notches (30°,45°, and 60°)
2. Angle Indicators
3. Offset Multipliers
4. Back of 90° Bend Indicator
Good practices and tips:
• Always measure first
• Use the tables on the bender's handle or in this instruction sheet to mark the conduit.
• Match the marks to the markings on the bender.
• When bending against the ground, pin the conduit down using heavy foot pressure to keep the
conduit in the groove and prevent kinks.
• When bending in the air, pin the conduit against your body.
To make a simple stub bend:
1. Mark the conduit.
2. Line up the Alignment Arrow with the mark.
3. Bend to 90°.
NOTE: Use the following to calculate the marking location:
Desired stub height - Indicated tool stub height = Marking location for alignment arrow
Back-To-Back Bends
To make U-bends in a single piece of conduit:
1. Make the initial stub bend.
2. Measure and mark the conduit where the back of the U-bend will be. This is the side that will
run against the floor, ceiling or wall.
3. With the bender hook facing away from the previous bend, line up the mark with the star (Back
of 90° Bend) indicator.
4. Bend to 90°
To make an offset bend due to work around an obstacle, resulting in the conduit running along a
different plane:
1. Determine the most appropriate offset angle, keeping in mind the function of the bend.
2. Measure the distance from the coupling to the obstacle.
3. Use the Offset Table to determine the appropriate Offset Angle.
4. Find the corresponding Offset Depth.
5. Add the Shrink Amount and mark the conduit.
6. Measure the Distance Between Marks and mark the conduit again.
7. Line up the Alignment Arrow with the first mark and bend to the offset angle chosen
8. Rotate the conduit 180°.
9. Line up the Alignment Arrow with the second mark and bend to the offset angle chosen.
To make a saddle bend due to work around an obstacle, returning the conduit to the same plane:
1. Use the same calculation for both sets of angles. a 45° center bend with two 22-1/2° outer bends
is most common.
2. Find the SADDLE DEPTH in the
Saddle Table.
3. Find the center of the bend, and
mark it accord-ing to Place Center
mark "A" Ahead of Actual Center By.
4. Mark the other bends according to
Place Marks "B" and "C" Each Way
From Center.
5. Line up the Center of Bend Indicator
on the A mark.
6. Bend to 45°.
7. Slide the conduit down and line up
the Alignment Arrow with the B mark.
8. Bend to 22-1/2°.
9. Remove the conduit and rotate it
180°. Line up the Alignment Arrow
with the C mark. NOTE: Be sure the
bend is in the same plane.
10. Bend to 22-1/2°.
11. See the following example.
Saddle Formula
Distance from Mark "A" to Marks "B" and "C"=2.5 x Saddle Depth
Example
Saddle over a 2" diameter pipe; center of pipe is located 15" from the box
