IMPORTANT SAFETY INFORMATION
• Conduit moves rapidly as it is bent. The path of
the conduit must be clear of obstructions. Be
sure clearance is adequate before starting the
bend.
• Do not operate the bender while wearing loose
clothing. Loose clothing can get caught in moving
parts.
• Inspect the bender before use. Replace worn,
damaged or missing parts with Greenlee replace-
ment parts. A damaged or improperly assembled
component could break and strike nearby
personnel.
• Some bender parts and accessories are heavy
and may require more than one person to lift and
assemble.
• Use this tool for the manufacturer’s intended
purpose only. Use other than that which is
instructed in this manual can result in injury or
property damage.
Failure to observe these precautions can result in
injury or property damage.
Make sure that the handle is properly installed and
secured with the safety spring clips and snap pins
before lifting or moving the bender. An improperly
installed handle could allow the bender to fall,
injuring nearby personnel.
Failure to observe this warning can result in severe
injury or death.
Unplug the bender before changing accessories.
Accidental start-up can result in serious injury.
Pinch points:
Keep hands away from bending
shoe, rollers and conduit when
bender is in use.
Extension cords:
• Use only three-wire, 12-gauge
extension cords that have three-
prong grounding-type plugs and
three-hole receptacles that accept
the tool’s plug.
• Do not use extension cords that
are longer than 30 m (100').
• Repair or replace damaged
extension cords.
Failure to observe these warnings
can result in severe injury or death.
Bending shoe weighs 42 kg (92 lbs)
and may require more than one
person to lift and assemble.
Failure to observe this warning can
result in severe injury.

Grounding Instructions 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.
Electric shock hazard:
• Do not modify the plug provided
with the tool.
• Connect this tool to a grounded
receptacle on a 20 amp ground
fault protected circuit.
Failure to observe these warning
can result in severe injury or death.

ADJUSTING THE SQUEEZE
When bending 1-1/4" to 2" EMT, IMC and rigid alumi-
num conduit, the roller support must be engaged so that
it contacts the conduit; the pressure against the conduit
is the “squeeze.”Typically, the squeeze adjustment arm
is vertical (at middle hole) but can be changed by
moving the position of the thumbscrew.
Due to variations in conduit, the standard adjustment
may provide too much or too little squeeze. If the
conduit develops excessive side marking when bent,
the squeeze is set too high; decrease squeeze one
position (hole) clockwise. If the conduit becomes
excessively oval or wrinkled, the squeeze is set too low;
increase squeeze position (hole) counterclockwise.
When bending 1-1/4" to 2" aluminum rigid conduit,
decrease the squeeze by three settings.
Adjusting the Squeeze
ADJUSTING THE ROLLER SUPPORT ASSEMBLY
LOCATION
If the conduit develops excessive side marking when
bending in the horizontal position, the location of the
roller support assembly might need adjusting. Loosen
the left-hand and right-hand locator screws for the
Roller Support Assembly (see p. 6) to align the center-
line of the roller with the centerline of the shoe groove.
Retighten the locator screws.

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; see distance “d”in the illustration at left.
gain —the difference between the straight-line distance
(a + a) and the shorter radial distance, (d) where:
θ= 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; see the expla-
nation under Offset Bending in this manual.
springback —the amount, measured in degrees, that a
conduit or pipe tends to straighten after being bent.

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.

Additional Bending Instructions
The following drawings and bending tables are intended
to provide the information necessary to accomplish the
most common types of bends. The Bending Tables
contain conduit marking information.
STUBS
1. Select the size and type of conduit. Determine the
height of stub and the angle to be used.
2. Find the table that corresponds to the size and type
of conduit selected in Step 1.
3. Under the column labeled ANGLE, find the appro-
priate angle.
4. Find the row labeled Y. In the row at the top of the
page, find the height (H) of the stub. The number
shown at the intersection of row Y and column H is
the distance Y. Place the bending mark Y inches
from the end of the conduit.
5. Bend the conduit.
OFFSETS
An offset is used to route the conduit around an obstruc-
tion. 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 first 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 first 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, find the
dimension labeled X. Subtract X from LENGTH.
Place the first bending mark this distance from the
end of the conduit.
4. Under the column labeled ANGLE, find the appro-
priate angle. Find the row labeled L1. In the row at
the top of the page, find 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 first bending mark.

LENGTH and the HEIGHT.
2. Find the table that corresponds to the size and type
of conduit selected in Step 1.
3. Under the column labeled ANGLE, find 90°.
4. Find the row labeled Y. In the row at the top of the
page, find the height (H) that corresponds to the
LENGTH. The number shown at the intersection of
the Y row and the appropriate H column is the
distance Y. Place the bending mark Y inches from
the end of the conduit.
5. Find the row labeled L1, and go to the right to find
the height (H) that corresponds to the HEIGHT.
6. The number shown at the intersection of the L1 row
and the appropriate H column is L1. Place the
second bending mark L1 inches from the first mark.
7. Bend the conduit.
