Unpacking
Remove all bender shoes, follow bars, U-straps and
pins. Inspect for damage and compare these
components to the complete set shown on page one
for possible missing parts. Depending on which set
you purchased - the basic difference in component
content will be whether you purchased a set having
the 31⁄2" size shoe, follow bar and U-strap included.
Maintenance of your Eegor® Bender
Aside from conventional care of the hydraulic
components, very little maintenance of the Eegor®
bender is required. Removing sand or dirt from
grooves and moving parts will extend bender life and
facilitate ease of operation.
Lubricate rollers, when needed, with molybdenum
disulfide paste only (such as Dow Corning’s
Molykote #G-n paste, or equivalent). For heavy
use, lubricate rollers weekly. Note: Graphite
formulations are not equivalent lubrication.
Bender Frame Assembly -
Removal, Transporting & Storage
To remove or carry the bender frame assembly—do
so by placing hand on the bottom frame plate. You
should have assistance so that the lifting points are
at the front end and back end of the bottom plate.
Avoid pinched fingers by keeping
hands away from the BZ72 roller assembly, which
pivots freely on a pin through the cylinder rod eye and
may swing suddenly aside during handling.
The hydraulic cylinder, cylinder mounting block and
compression roller assembly slide back and forth
between the two frame plates.
This sliding action is a function of the bender design
for locating the cylinder to meet the need of your
particular conduit size; up to a full 90˚ without the need
of another set-up or reposition of the conduit.
The slide action permits the bender assembly to be
collapsed to a shorter length for handling and storage.
When storing, be sure to remove the hydraulic hoses
from the cylinder and install dust caps on the coupler
ports. See the back page for details of storing the
B400DL and B400L models.

Introduction
Gardner Bender™ produces twelve versions of the
Eegor® hydraulic conduit bender. Each version uses a
hydraulic cylinder and electrically operated pump to
produce the force necessary to bend conduit sizes
21⁄2" to 4". Differences between model numbers are
based on the accessories included with each model
and the length of the cylinder used to bend the
conduit. Since the process of bending is the same for
all models, the instructions and safety precautions
apply to all application and uses of Gardner Bender™
hydraulic conduit benders.
Bending conduit encounters a wide range of situations
and a variety of conduit materials. Because of the
multiple job specifications, it is not possible to provide
instructions covering every situation. Principal bending
formulas apply to use of the model B400 series
benders. Assembly instructions are specific. Follow
them precisely to ensure safe, reliable and effective
conduit bending.
All instructions are important, but safety alert
symbols are located throughout this manual, and a
separate section is included to address specific
safety concepts.
Before operating Gardner Bender™ conduit benders,
read and understand this entire manual. If any
subjects are not understood, contact Gardner Bender
at 414-352-4160; ask for technical services.

The Eegor® bender develops 30 tons of force at 9,250
psi. Greater forces will be generated between the
rollers, follow bars and bending shoe. Operators must
follow instructions for assembly and bending conduit
to avoid pinch points and applying forces to incorrect
bender components.
Do not use damaged parts to assemble the
Eegor® bender. Items that are damaged or broken
due to extensive wear must be replaced to avoid
potential hazards to the operator.
Keep hands and loose clothing away from all moving
parts. Frames and rollers move under high pressure.
Do not place hands on conduit or between conduit
and follow bar during operation. Severe injuries could
result.
Do not connect or disconnect hydraulic hose fittings
with pressure in the system. A rigid hose indicates the
presence of internal pressure. Prior to electrical or
hydraulic repairs, retract the hydraulic cylinder and
turn off the hydraulic pump.

5. Install the two hydraulic hoses. Apply one wrap of
teflon tape to the threads on the end of the hose.
Remove the pipe plugs from the pump valve, one
port is marked “ADV” the other is marked “RET”.
Install a hose in each port. Figure 5.
6. Connect the hose from the “ADV” port to the
hydraulic cylinder coupler located near the base
of the cylinder. Make sure there is no dirt or
debris in either half prior to assembly. Push the
hose coupler firmly into the cylinder coupler, then
tighten coupler collar. Connect the hose from the
“RET” port to the remaining cylinder coupler.
Figure 6A & 6B.
IMPORTANT: The hose coupler must be firmly
seated in the cylinder coupler and held
tightly while turning the coupler collar.
Hand tighten the collar. Do not use
tools to tighten. Failure to properly
assemble couplers will inhibit oil flow.
8. The lower plate and roller assembly remain
in position during normal shoe and follow
bar installation.
Bending Shoe and
Follow Bar Installation
A. Model B400L and Model B400DL Ultra Eegor™
1. The B400L and B400DL use a 28" hydraulic
cylinder. As a result, the upper and lower plate
assemblies use the 31⁄2"–4" frame holes for
mounting all sizes of conduit bending shoes. See
figure 8. For smaller sizes of conduit, the cylinder
plunger must be advanced to position the roller
assembly against the follow bar.

of the follow bar in place by pushing it forward.
Do not place fingers between follow
bar and conduit. Severe injury
will result.
7. Press “Advance” button to begin bending. Once
follow bar engages all rollers and bend begins, let
go of the follow bar. Continue holding the
“Advance” button until the bend is complete or the
cylinder reaches maximum length.
8. Large 3", 31⁄2", and 4" conduit require two cycles
of the hydraulic cylinder. When the first stage is
complete the cylinder will stop and the pump
motor will begin to stall. Release the “Advance”
button. Press return (momentarily) to release
pressure on the anchor pin. Do not remove the
conduit shoe or follow bar from the bender.
9. Lift and remove the anchor pin. Press “Retract”
button until cylinder mounting block grooves are
aligned with holes marked 21⁄2". Replace the
anchor pin through the top frame, cylinder block
and lower frame. Figure 26.

Reading Bend Angles
1. Bend angles are printed on the upper frame decal.
Locations exist for Rigid, IMC and EMT conduit.
Locate the mark indicating the type of conduit and
the angle desired. Figure 27.
To avoid damaging the anchor pin, be
sure both pin shafts protrude through
the holes in the lower frame.
10. Press “Advance” button until bend is complete.
2. During the bend the bronze roller shaft travels
through the slot in the upper frame. A line is
scribed on the shaft. When the line on the shaft
reaches the bend angle you have selected, the
bend is complete.
B. B400L and B400DL
1. The cylinder mounting block must be positioned
at the 31⁄2"–4" holes of the upper frame.

and hold it until the conduit returns to the starting
position.
When the conduit returns to the
starting position, the conduit and
follow bar become loose enough to fall
out of the bender. Grab the follow bar
to prevent it from falling out of the
roller assembly.
11. Remove the follow bar, then remove the bent
conduit from the roller assembly. Turn pump off.
!CAUTION
Follow Bar
Synchronization - Removal
Occasionally your follow bar may become out of
synchronization with the movement of the bend shoe
on the return cycle.
If this happens, care should be taken by visual
inspection as you are retracting the cylinder. Figure 36
illustrates what to look for in an out-of-phase
condition. You will note the follow bar slipped forward
over the strap, rather than the front end of follow bar
remaining behind the strap.
Procedure for Removal
1. After completing desired bend, retract the bend
shoe until the strap is close to the follow bar as
shown in figure 36. Do not retract further or make
contact with the U-strap against the follow bar or
breakage could occur.

To Make a Stub-up or Kick Bend
1. Determine “H” dimension by measuring rise
or height needed. From “Diagonal Distance
Chart” at right, determine straight length of
pipe (D) needed to reach to desired turn-up
height (H) at desired bend angle.
2. Lay off this distance (D) from end of conduit
and make first mark.
3. From “Set-back Chart”, select proper
set-back dimension (S) corresponding to
conduit size and bend angle desired.
4. Measure distance (S) back from the first mark and make second mark (see figure above).
5. Place conduit in bender with second mark aligned with leading edge of U-strap (see figure above) and bend
conduit to desired angle.

Additional Bending Data for Eegor® Benders
Developed Length of Bend:
When conduit is bent, the length along the bend at the neutral
axis (i.e., approximately the centerline of the pipe) is commonly
called “developed length” of the bend.
Gain of Bend:
The difference between the “squared off” distance (AB + BC) around a corner and the “developed length” (AC)
along a bend is commonly called “gain” of the bend. (Measurements should be made at the pipe centerline.)

Offset Bend Instructions
for the Eegor® Bender
Bending Offsets
Offset bending is easy with the added
benefit of bending good close offsets.
A. To bend the offsets, proceed to bend
in the normal manner covered above
until the desired bend is reached.
See Figure 39.
B. Retract and strip out conduit. Rotate the conduit and locate as shown for the second bend. Complete the
second bend, retract and strip out conduit for a good offset bend.
When making offset bends, caution should be taken not to attempt too tight an offset. The follow bar will
lift off the conduit when starting the second bend if it is too tight. Stop bending immediately or damage
could occur to the bender. Correction is achieved by shifting the conduit so the U-strap engages the
conduit more closely to the unbent portion of the conduit.

To Make an Offset Bend:
1. Make first mark at location determined either by edge of obstacle or
by following “Kick Bend Instruction for Eegor® Benders” (page 11).
2. From the “Offset Chart” for the size of conduit to be bent, obtain
measurement (B) for offset height (H) and bend angle desired.
3. Make second mark at distance (B) beyond first mark and on opposite side of conduit as
illustrated above.
4. Place conduit in Eegor® bender with first mark aligned with leading edge of U-strap (see figure above) and
make first bend to the desired angle.
5. Advance the bent conduit through the frame assembly of the Eegor® bender and rotate the conduit 180°, so
the second mark aligns with the leading edge of the U-strap.
6. Complete offset by making second bend to the exact same angle as the first bend.
