Features
The 855 bender is designed to make high quality bends
of up to 90 degrees in 1/2" to 2" EMT, IMC, rigid steel,
and rigid aluminum conduit. It incorporates a number of
features to make bending easier and faster.
• Four large wheels allow easy transportability.
• Powerful motor and efficient gearbox can bend 2" rigid
in 11 seconds.
• Working height at waist level reduces need for the
operator to bend over.
• All conduit bending can be done without changing
shoes or rollers.
• Conduit bending can be done in a vertical plane while
keeping the conduit level or in a horizontal plane to
allow making kicks and offsets.
• Simple roller system automatically adjusts to EMT or
IMC conduit sizes.
• The zero position for bending is automatically set by
selecting the size and type of conduit to be bent prior
to bending.
• Bender automatically compensates for conduit spring-
back so you simply bend to the desired angle without
using charts.

855 Smart Bender™
Setup
When you reach your destination, lower at least two
jackscrews to prevent the unit from rolling. If desired, all
four jackscrews can be used to level the unit. Rotate the
bender head to the position you desire to bend in. To
rotate the bender head, pull out the round pivot lock
knob while pivoting the head in the desired direction.
If the knob is difficult to pull out, turn the knob clockwise
until it pushes against the frame to break it free. When
the bender is in the desired position, make sure the
detent pin fully engages in the hole. To reduce the
amount of free play in the bender head, turn the knob
counterclockwise until some resistance is felt.
Remove the pendant control from its storage area and
plug it into the four-pin pendant receptacle on the side of
the bender power head. This must be plugged in
before the bender is turned on or it will not operate.
Plug the power cord into a 120 VAC, 20 amp GFCI-
protected receptacle and turn the power switch on. Wait
until the display comes on before pressing any keys or
the bender will not operate.

Use lifting eyes for hoisting
Lift only with bending head in a horizontal position

Transportation
The only proper way to lift this bender is by attaching
nylon or polyester slings or chain and hooks to the
lifting eyes. The bender head must be in the table-top
position as shown below with the 1-1/2" to 2" shoe up.
Rotate the eyes up
so that the slings
or hooks can be
hooked to or
looped through the
eyes. Make sure
that each side of
the sling or chain
is at least 3' long
to prevent it from
rubbing against the
bender. Make sure
all components
used to lift this
bender are prop-
erly rated for the
231 kg (510 lb)
weight. Use a
ramp to load and
unload from a
truck or other
vehicle that is not
equipped with a lift
gate. To transport
around the jobsite,
first assure that the jackscrews are retracted enough to
clear the terrain.
Pull out on the bender head pivot lock knob. If the pivot
lock knob cannot be pulled out far enough for the detent
pin to clear the frame, turn the knob clockwise until the
detent pin clears the frame. Rotate the bender head so
that the 1-1/2" to 2" shoe is up. Make sure that the
detent pin locks into position. Turn the pivot lock knob
counterclockwise until resistance is felt to lock the pin in
position.
To prevent the bender from rolling on its own, lower the
kickstand (optional). It is located between the two swivel
wheels. To set the kickstand, apply foot pressure to the
lever above the stand until it contacts the ground and
then push the bender away from you until it rolls up
onto the stand. To take the bender off the stand, push
down on the lever below the crossbar and pull the
bender toward you until it rolls off the stand.

Operation — Standard Pendant
Set the type and size of conduit you will be bending
with the rotary selector switches located on the side
of the bender.
Failure to do so may result in the shoe rotating the
opposite direction than expected.
Bend Key: runs the shoe in the direction to bend the
conduit according to which conduit size has been
selected by the rotary size selector switch. The BEND
key functions only while it is pressed. The BEND key
ceases to function once it reaches the maximum shoe
travel or an angle stored in memory.
Jog Key: runs the shoe in the direction to bend the
conduit according to which conduit size has been
selected by the rotary size selector switch in 1/2-degree
increments. The JOG key functions any time it is
pressed until the maximum shoe travel is reached.
Unload Key: runs the shoe backwards according to
which conduit size has been selected by the rotary size
selector switch. The UNLOAD key functions when it is
pressed unless the roller support locking cam is locked
in position.
Note: The shoes can rotate a restricted amount in the
bend direction. When the maximum has been reached, the
BEND and JOG keys will not function. Use the UNLOAD
key to rotate the shoes to the proper load position.
Angle Select L : is used to set the desired bend angle
into memory. Pressing it for a moment increases the
present angle in memory 1 degree at a time. Holding it
down rapidly advances the memory angle.
Angle Select M : functions the same as the ANGLE
SELECT UP key except it decreases the angle.
Clear Key: sets the display to 00 and eliminates any
angle from memory. It will not reset the actual present
bend angle to zero.

Display: shows the actual angle the conduit has been
bent in degrees. Counting does not start until the
conduit actually starts to bend. If an angle is stored in
memory, the display shows the stored angle at all times
except while the BEND, JOG, or UNLOAD keys are
depressed and for about 2 seconds after they are
released. The display will not show angles greater than
99 or less than 0.
Upon power-up the display will show H., which indicates
that the home position must be set on the bender before
installing conduit. Press UNLOAD until the shoe hook
for the size and type of conduit selected is at the bottom
(5 o’clock position). Press BEND until the pendant
display changes from H. and starts counting. Then
press UNLOAD until the shoe rotates backwards and
stops. This is the proper load position for the selected
size and type of conduit and home position is now set.
The display will show H. each time there is a change in
conduit type setting, a change in conduit size to the
other shoe, and when power to the bender has been
interrupted.
Accuracy Adjust Mode: due to variations in conduit,
you may notice the bender consistently over or under
bending a particular size and type of conduit. The
accuracy adjustment mode allows programming correc-
tions for over and under bending conduit. Minus 9 to
plus 9 degree adjustments can be made for each size
and type of conduit. Press and hold CLEAR, then press
and hold BEND until Pr is displayed. Release controls
and adjust the degrees of bend by pressing the ANGLE
SELECT up and down controls. ANGLE SELECT UP
increases and ANGLE SELECT DOWN decreases the
bend angle for the size and type of conduit selected by
the rotary selector switches. CLEAR resets the adjust
angle to zero. Any adjust angle may be displayed by
setting the rotary selector switches to the desired size
and type of conduit. Press BEND to save the adjust
angle and exit the Adjust mode. Only changes to the
last displayed value will be saved. Changes saved are
to permanent memory in the bender and can only be
changed by reprogramming. The pendant will display
oP for two seconds when the bender returns to the
normal operating mode.

selected is at the bottom (5 o’clock position). Press
BEND until the pendant display changes from H. [or
SET HOME POSITION on the deluxe pendant] and
starts counting. Then press UNLOAD until the shoe
rotates backwards and stops. This is the proper load
position for the selected size and type of conduit and
home position is now set. After you start bending, the
bender automatically stops at this load position when
UNLOAD is pressed. The standard pendant displays H.
[SET HOME POSITION on the deluxe pendant] each
time there is a change in conduit type setting, a change
in conduit size to the other shoe, [RESET key is

bender has been interrupted. Home position can only be
set when the shoe rotates in the bend direction.
Note: The shoe can rotate a restricted amount in the
bend direction. When the maximum rotation has been
reached, BEND and JOG keys will not function. Always
use the UNLOAD key to rotate the shoes to the proper
load position.
The shoe grooves for EMT conduit use silver hooks, the
shoe grooves for IMC and rigid (steel and aluminum)
conduit use green hooks, and the optional shoes for
bending 40 Mil PVC-coated steel rigid conduit have
black hooks. Insert the conduit into the proper shoe
groove and hook. Align the bend location marks with the
front of the hook. If you wish to side load the conduit,
rotate the shoe hook to the 5 o’clock position.
• Do not allow a bend or coupler to go over the
roller supports.
• Do not allow the trailing end of the conduit to go
over the roller supports.
Failure to observe these warnings can result in
severe injury or death.

MANUAL BENDING
Make sure that no angle is set in memory. The memory
is clear if the pendant display shows 00 when BEND,
UNLOAD or JOG are not depressed. If 00 is not
displayed, press CLEAR. [The memory is clear if no
angle is shown in the top row of the terminal display and
is prompting for a bend type]. If an angle of 93 degrees
is reached at any time while pressing BEND or JOG, the
bender will stop to prevent accidentally running a hook
into the conduit. Always use the UNLOAD key to rotate
the shoe to the desired position.
1/2" to 1-1/4" Conduit
Press the BEND key while maintaining conduit align-
ment until slack is taken up. When the conduit starts to
bend, the digital display starts to count from zero and
show the angle to which the conduit has been bent.
The angle displayed has already compensated for
springback. When you reach your desired angle,
release the BEND key. It might be beneficial to stop
slightly before the angle to account for reaction time and
motor braking time and then use the JOG key to
advance the bend in 1/2-degree increments to prevent
overbending.

Apply sufficient force on the handle so that the roller
system reaches its position against the stops before the
conduit starts to bend. Supporting the tail end of a long
conduit may ease engagement when bending vertically.
Continue to press the BEND key while maintaining
conduit alignment until slack is taken up. When the

A roller support lock has been provided to free up one
hand. Once the roller support engagement handle is
brought up into position, a locking cam holds the handle
in place and bending can proceed from this point
without further operator action on the handle. Lifting up
on the tail of the conduit makes roller engagement
easier. For 1-1/2" EMT, it may be easy to go past the
cam; if this happens, raise the cam by hand and rest the
handle against it. If you wish to change the position of
the conduit and it is held too tightly to move, rotate the
handle counterclockwise to disengage the cam. Reposi-
tion the conduit and relock in place. The UNLOAD key
will not function while the locking cam is engaged.
Note: If you are unable to raise the handle enough to
engage the locking cam even after lifting up on the tail
of the conduit or pushing down on the nose, the
squeeze is probably set too high. If the handle easily
passes by the cam on 2", the squeeze is probably set
too low.
PROGRAMMED BENDING
Press the ANGLE SELECT UP key to place an angle
into memory. Pressing it momentarily advances the
stored angle 1 degree at a time. Holding it down rapidly
advances the angle. Release it when the desired angle
is obtained. Use the ANGLE SELECT DOWN key to
reduce the angle in memory. It operates the same as
the ANGLE SELECT UP key does. The ANGLE
SELECT DOWN key can also be used to initiate putting
an angle in memory. For large angles, this would be
faster. Press the CLEAR key to remove any angle from
memory and set the display to 00. If an angle is stored
in memory, it will be displayed whenever the BEND,
JOG or UNLOAD keys are not depressed. [Press the
ANGLE key on the deluxe terminal and enter an angle
using the 10 numerical keys. The decimal is not used
for angles. Press ENTER to set the angle in memory.] If
an angle of 93 degrees is reached at any time while
pressing BEND or JOG, the bender will stop to prevent
accidentally running a hook into the conduit. Always use
the UNLOAD key to rotate the shoe to the desired
position.
Accuracy Adjustments
Due to variations in conduit, you may notice the bender
consistently over or under bending a particular size and
type of conduit. Programmed adjustments can be made
to compensate for over and under bending conduit.
Minus 9 to 9 degree adjustments can be made for each
size and type of conduit. Press and hold CLEAR and
then press and hold BEND until Pr is displayed.
Release the keys and adjust the degrees of bend by
pressing the ANGLE SELECT UP or ANGLE SELECT
DOWN keys. ANGLE SELECT UP increases and
ANGLE SELECT DOWN decreases the bend angle for
the size and type of conduit selected by the rotary
selector switches. CLEAR resets the adjust angle to
zero. Any adjust angle may be displayed by setting the
rotary selector switches to the desired size and type of
conduit while in the Accuracy Adjust programming
mode. Press BEND to save the adjust angle and exit
the Adjust mode. Only changes to the last displayed
value will be saved. Changes saved are to permanent
memory in the bender and can only be changed by
reprogramming. The pendant will display oP for two
seconds when the bender returns to the normal operat-
ing mode.
1/2" to 1-1/4" Conduit
Press the BEND key while maintaining conduit align-
ment until slack is taken up. When the conduit starts to
bend, the digital display starts to count from zero and
show the angle to which the conduit has been bent. The
angle displayed has already compensated for
springback. As the conduit approaches the programmed
angle, the bender slows and then stops at the pro-
grammed angle. Releasing the BEND key at any time
during the bend stops the bender. The bend can then
be resumed from the point it was stopped. After stop-
ping at the programmed angle, the BEND key will
function if released and pressed again. The JOG key
can be used to bend beyond the programmed angle in
1/2-degree increments.

UNLOADING
When the conduit is bent to the desired angle, press the
UNLOAD key until the shoe has rotated back about 10
or more degrees. Twist the conduit to free it from the
hook and remove it from the shoe. Continue to press
UNLOAD and the bender will automatically stop at the
best position for end-loading the next conduit. If you
want to side-load the conduit (or use the opposite side
of the shoe), you need to unload beyond this point. To
do so, simply release the UNLOAD key and press it
again. The bender will proceed to unload. Release the
UNLOAD key when the shoe has rotated to the desired
position.
MAKING ANOTHER BEND
To make another manual bend, proceed as you did with
the first one. To make another programmed bend of the
same size, type and angle, load and bend the conduit
just as you did the previous one. You may change the
programmed angle and make a bend to the new angle
without any additional changes. You can also change
the size and/or type of conduit and bend to the previous
angle; however, if your change requires using the
opposite side of a shoe, you need to use the UNLOAD
key to index the shoe. Do not use the BEND key to
index the shoe. Using the BEND key will cause the
bender to stop at the programmed angle. Pressing
CLEAR will eliminate this, but you will need to repro-
gram the bend.
MAKING A FULLY PROGRAMMED BEND
ON DELUXE PENDANT
Select the size and type of conduit to be bent as previ-
ously instructed. Select the type of bend you wish to
make, using one of the three bend type keys (STUB,
OFFSET or SADDLE). Enter the angle to be bent to,
using the numerical keys (0 to 9). Press ENTER. The
decimal key is not used for angles. Enter the height of
the stub, offset or saddle, using any of the 11 numerical
keys. Press ENTER. The height is from the bottom of
the conduit to the center of the end of the conduit for
stubs, and from the bottom of the conduit to the bottom
of the second bend for offsets and saddles. If you are to
make an offset or saddle, enter the length of it using the
11 numerical keys. Press ENTER. The length is from
the end of the conduit to the beginning of the first bend
for offsets, and from the end of the conduit to the middle
of the saddle for saddles. The display screen will show
where to make your alignment marks. Place mark 1 on
the conduit the distance shown from the end of the
conduit. For offsets and saddles, place mark 2 the
distance shown from mark 1. For saddles, place mark 3
the distance shown from mark 2. Set Home Position if
required. Insert the conduit into the proper shoe groove
and hook and align mark 1 with the outside edge of the
hook.

855 Smart Bender™
This section of the manual describes how to disas-
semble and replace parts in the Greenlee 855 Smart
Bender™. Parts must be ordered from Greenlee
Textron.
Service of this bender should only be done by qualified
personnel who are familiar with handling of electronic
components. The 855 Smart Bender™ warranty will
become void if unauthorized repairs are attempted or
non-specified parts are used in repairs. For information
on parts or repair procedures not shown in this docu-
ment, contact your nearest Authorized Greenlee
Service Center or call 800-435-2932.
SERVICE
Disconnect power supply before
servicing bender. Servicing to be
done only by trained service
technician.
Failure to observe this warning can
result in severe injury or death.
Adjustments
Squeeze
Proper squeeze adjustment for most 1-1/2" and 2" EMT
and IMC conduit is when the squeeze adjustment arm is
vertical (at middle hole). But variation in conduit can
result in wrinkling or side marking of conduit. If wrinkling
or excessive ovalness occurs, increase squeeze one
position (hole) counterclockwise. If loading conduit is
difficult or if excessive side marking occurs, decrease
squeeze one position (hole) clockwise.
Accuracy
If the accuracy of all sizes of conduit on one shoe is off
in the same direction, the limit switch needs to be
adjusted. Individual adjustments specific to one size and
type of conduit should be made using the Accuracy
Adjust mode (see Operation — Standard Pendant).
To adjust the limit switches, first unplug the bender.
Remove the four screws that secure the top round
guard and remove the guard to expose the two limit
switches. The top switch controls the 1-1/2" to 2" shoe.
Loosen the two screws and move it to the right side of
the bender as shown in the diagram below to prevent
overbending. The bottom switch controls the 1/2" to
1-1/4" shoe. Loosen the two screws and move it to the
left side of the bender as shown below to prevent
overbending. Move either switch the opposite direction if
the bender is underbending. Every 1/8" of switch
movement approximates 1 degree of change. Tighten
the screws and replace the guard.

Adjustments (cont’d)
Retention Cam
Loosen the screws securing the retention cam. With the
bender oriented in the vertical position, rotate the round
plate until the right side edge of the cam is pointed
straight down or within 1/4" left of being straight down.
Make sure both ends of the spring are engaged in the
holes of the cam and round plate. Tighten the screws
while holding the round plate in position with pliers to
prevent it from rotating.
1/4"
Check to make sure the roller support handle will fully
engage and retract without catching on the cam holding
surface. This should be done in both the vertical and
horizontal bending positions. It should also be done with
the cam positioned as far left and as far right as friction
will allow it to stay.
Cam Holding
Surface
Once everything is tightened down in the proper posi-
tion, push in the limit switch trip arm. You should hear
the switch click on. If not, loosen the two screws and
nuts and slide the switch to the right and retighten.
Push the cam toward the switch to make sure any free
play will not trip the switch.
Tripping Surface
of Cam
Limit
Switch
Arm
Rotate the cam until the switch trip arm rides up on top
of the tripping surface of the cam. You should hear the
switch click on. If not, move the switch to the left to a
point where it does. You should hear the switch click off
when the cam is released. If you cannot move the
switch enough to get it to trip properly, use needlenose
pliers to slightly bend the arm.
Chain Lubrication
Lubrication of the drive chain is recommended every
six months (more often if used in dusty or corrosive
environments).
1.
Disconnect power to unit.
2.
Remove the 1-1/2" to 2" shoe.
3.
Remove the lower front guard.
4.
Spray a motorcycle chain lubricant on the inside of
the chain between the sprockets while pressing
UNLOAD until the entire length of chain has been
covered (do not spray on the encoder beneath the
drive sprocket).
5.
Replace the guard and shoe.
Chain Adjustment
Check the free play in the chain every time the chain is
lubed. If the total play halfway between the sprockets is
more than 1", adjust the chain.
1.
Disconnect power to unit.
2.
Remove the 1-1/2" to 2" shoe.
3.
Remove the front lower guard and the motor
cover.
4.
Loosen the two motor mounting bolts on the front of
the bender and the two mounting bolts and one nut
on the back.
5.
Turn the lower bolt on the front clockwise until all
chain slack is removed. While maintaining tension,
tighten the nut and two front bolts.
6.
Tighten the two rear bolts.
7.
Replace the motor cover, guard and shoe.
Brake
Under normal circumstances the brake should not require
adjustment. However, if the brake can be heard dragging
while bending or if the braking performance deteriorates,
brake adjustment may be necessary.
1.
Disconnect power to unit.
2.
Remove the motor cover.
3.
Loosen the two set screws on the brake rotor hub
(the part that turns).
4.
Slide it to a position .002" to .015" away from the
mating face (about 1 to 3 page thicknesses of this
manual).
5.
Tighten the set screws to 4 Nm (35 in-lb).
6.
Replace the motor cover.
Maintenance
Do not touch the brake if the bender
has been recently used. It will be
hot. Wait an hour for it to cool off
before adjusting.

holding the round plate in position with pliers to
prevent it from rotating.
1/4"
• Check to make sure the roller support handle will
fully engage and retract without catching on the
cam holding surface. This should be done in both
the vertical and horizontal bending positions. It
should also be done with the cam positioned as
far left and as far right as friction will allow it to
stay.
Cam Holding
Surface
• Once everything is tightened down in the proper
position, push in the limit switch trip arm. You
should hear the switch click on. If not, loosen the
two screws and nuts (40 and 41) and slide the
switch to the right and retighten. Push the cam
towards the switch to make sure any free play will
not trip the switch. Rotate the cam until the switch
trip arm rides up on top of the tripping surface of
the cam. You should hear the switch trip on. If not,
move the switch to the left to a point where it
does. You should hear the switch click off when
the cam is released. If you cannot move the
switch enough to get it to trip properly, use
needlenose pliers to slightly bend the arm.

If the accuracy of all sizes of conduit on one shoe is
off in the same direction, the limit switch needs to be
adjusted. To do so, first unplug the bender. Remove the
four screws that secure the top round guard and remove
the guard to expose the two limit switches. The top
switch controls the 1-1/2" to 2" shoe. Loosen the two
screws and move it to the right side of the bender
(as shown above) to prevent overbending. The bottom
switch controls the 1/2" to 1-1/4" shoe. Loosen the two
screws and move it to the left side of the bender (as
shown above) to prevent overbending. Move either
switch the opposite direction if the bender is under-
bending. Every 1/8" of switch movement approximates
1 degree of change. Tighten the screws and replace the
guard.

SQUEEZE ADJUSTMENTS
Proper squeeze adjustment for most 1-1/2" and 2" EMT
and IMC conduit is when the squeeze adjustment arm
(74) is vertical (at middle hole). But variation in conduit
can result in wrinkling or side marking of conduit. If
wrinkling or excessive ovalness occurs, increase
squeeze one position (hole) counterclockwise. If loading
conduit is difficult or if excessive side marking occurs,
decrease squeeze one position (hole) clockwise.

If the chain breaks, replace it with a new
chain — not another master link — due
to the high stress on the chain. The
addition of a second master link will only
weaken the chain further. If the master
link breaks, replace it with a new master
link (905 4251.7).
