Operation (cont’d)
ADJUSTING THE SQUEEZE
When bending 1-1/4" to 2" EMT, IMC and rigid aluminum 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 centerline of the roller with the centerline of the shoe groove.
Retighten the locator screws.

successive bends that make up an offset or a three-bend
saddle.
r
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:

Additional Bending Instructions
OFFSETS
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.
An offset is used to route the conduit around an obstruction. To make an offset, two equal bends are required.
The distance between the two bends is the center-tocenter distance.
STUBS
When working past an obstruction, it is necessary to
determine the location of the first bend. The center-tocenter 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.
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 appropriate angle.
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.
3. Under the column labeled ANGLE, find the appropriate angle. Find the row labeled Z. In the row at
the top of the page, find the height (H) of the offset.
The number shown at the intersection of the Z row
and the appropriate H column is Z. Subtract Z from
the LENGTH. Place the first bending mark this
distance 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.
4. In the same column, find the row labeled L1. Place
the second bending mark L1 inches from the first
bending mark.
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.
5. In the same column, find the row labeled L2. Add L2
to the STRAIGHT SECTION. Place the third bending mark this distance from the first bending mark.
7. Bend the conduit.
6. Make the final bending mark L1 inches from the
third bending mark.

Handle Removal and Replacement
Transporting the Bender
The handle of the 853 is removable. This feature is
convenient when performing complex bending, and
makes it easy to replace a damaged handle.
Make sure that all components used to lift this bender
are properly rated for the 202 kg (445 lb) weight. Use
a ramp to load and unload the bender from a truck or
other vehicle that is not equipped with a lift gate.
Removal
To lift the bender, loop a nylon or polyester sling
through the spindle. Thread one end of the sling through
the length of the spindle as shown. Securely fasten to
lifting device.
1. Place the bender in the upright position.
2. Release the spring clip on the safety snap pin.
3. Remove the pin from the handle and the sleeve of
the frame.
Lifting Bender
4. Repeat for the other end of the handle.
5. Lift the handle to remove.
Replacement
1. Insert the handle into the sleeves of the frame.
2. Align the holes in the handle with the holes in the
sleeves.
3. Insert the safety snap pin. Ensure that the pin goes
through the handle and the sleeve on the frame.
4. Engage the safety spring clip over the end of the
pin. Ensure that the loop on the clip is completely
around the pin.
5. Repeat for the other end of the handle.
Removing or Replacing Handle
safety
snap
pin
Lift bender using a nylon or polyester sling through
the spindle. Do not attempt to lift bender by the
handles. Make sure all lifting components are
properly rated for the 202 (445 lb) weight.
Failure to observe this warning can result in severe
injury or death.
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.

Maintenance
There is no need for periodic flushing and replacing of
lube in the bender gear box since it is sealed and locked
tight. However, if the box is opened for repair and the
lube is lost or contaminated by dirt, then the box and
parts should be flushed out and filled with 26 fluid
ounces of Mobil® 634 synthetic oil.
Flushing should be accomplished with kerosene, which
is a petroleum hydrocarbon that does not affect seals.
Note: Aromatic hydrocarbons such as benzine,
chlorinated solvents such as carbontetrachloride, and ketones such as acetone
should never be used for flushing as they are
solvents for rubber. They are also harmful to the
environment.
Disconnect this tool when not in use,
before servicing or adjusting, and
when changing shoes or conduit
rollers and supports.
With the eight reductor mounting bolts loose, rotate the
eccentric cam with a 1/2" square drive to tension the
chain. Torque the eight reductor mounting bolts to 47
Newton-meters (35 foot-pounds).
Failure to observe this warning can
result in severe injury or death.
Chain Adjustment
Reductor
Mounting Bolt
Both chains have to be adjusted if the final drive #60
chain is to be reset.
Two eccentric cam mounting
holes provided for varying
adjustment positions.
Eccentric Cam
1. Remove the front cover and upper rear guard.
2. Loosen the eight mounting bolts for the reductor.
Remove the eccentric cam and move the reductor
to create chain slack.
Tab on
Reductor Bracket
3. Remove the four retaining screws for eccentric
adjustment. Rotate to remove slack from the chain
and align with one of the two sets of holes in the
frame. Remount the eccentric with the four bolts.
1/2" Square
4. Slide the reductor in slotted mounting holes to the
retension chain. Set tension with the eccentric cam.
Rotate eccentric cam counterclockwise.
Apply 20 Newton-meters (15 foot-pounds) of torque
to set chain tension. Then torque reductor mounting
bolts to 47 Newton-meters (35 foot-pounds).
