COULD result in minor personal injury or property damage. 13.0 BENDING INSTRUCTIONS
FOR 1-1/2" AND 2" EMT & IMC
1. See pages 5 and 6 for mounting shoes and support units. Be
sure to match the appropriate shoe with its corresponding
support unit.
NOTE: The outside roller on the 1 1/2” thru 2” IMC support unit is
steel. See Figure 10. The outside roller on the 1 1/2” thru 2” EMT
support unit is urethane. See Figure 11.
2. Mark the conduit to the desired length. Note that a 2” minimum
dimension is required to eliminate flattening the end of the
conduit. See Figure 12.
NOTE: “Stub-up”and “Offset” dimensions can be found on the
bending charts on pages 8 thru 10 of this manual or on the
bending instruction decal located on the top of each bender.
3. Rotate the bending shoe 5 to 10 degrees below the degree
setting. See Figure 8b.
4. After marking the conduit, place it into the bender. The conduit
should slide over the support rollers and through the shoe
groove and into the hook. The bending mark should be at the
front (OUTSIDE) edge of the hook. See Figure 12.
NOTE: The appropriate size and type of support unit MUST be
used with the corresponding shoe size and type.
5. Step on the “Engaging Pedal” which will raise the rollers to
come in contact with the conduit. See Figure 13. Be sure the
correct rollers for the size conduit being bent are in position to
engage the conduit.
NOTE: See SQUEEZE ADJUSTMENT PROCEDURE (Section 14).

6. Keep foot pressure on the engaging pedal and push the
Bend/Unload switch to the Bend position. Then press the Jog
button. The conduit will pull the support rollers against the
stop. Foot pressure can then be removed from the engaging
pedal. Be sure to check the alignment of the bending mark as
the rotating shoe locks the conduit into position.
Advance the bender shoe to the desired degree of bend. When
the pointer on the shoe reaches the desired degree of bend,
release the Jog button and the bender will stop.
NOTE: Due to springback in pipe/conduit, some overbending is
necessary to achieve the desired degree of bend. See page 9 or
the bending instructions decal located on the top of each bender
for approximate springback compensation figures.
NOTE: Do NOT allow the rollers to come in contact with the
bending shoe. The shoe and rollers squeeze the conduit but they
should never touch each other.
7. To release the conduit, place the Bend/Unload switch in the
Unload position. Press the Jog button and reverse the shoe.
The support rollers will then drop, allowing removal of the
conduit.
WARNING: The pipe/conduit should be under control when
unloading. Failure to do this may result in injury or death.
8. After removal of the conduit, inspect it for wrinkling or
excessive side marks. If these conditions occur, refer to the
Squeeze Adjustment Procedure (Section 14).
COULD result in minor personal injury or property damage. 14.0 SQUEEZE ADJUSTMENT
FOR 1-1/2" AND 2" EMT & IMC
The B2555 bender has a Squeeze Adjustment feature if wrinkling
or side marking becomes a problem during the bending process.
This feature allows you to increase or decrease the amount
of pressure applied to the conduit during bending, thereby
eliminating these problems. Begin with the 1/2" starting location
of the adjusting bolts as shown in Figure 14.
1. If wrinkling occurs, pressure against the conduit during the
bending process must increase. To increase the squeeze
(pressure), loosen both set screws and turn both adjusting
bolts one-half turn clockwise. Tighten both set screws and
bend one piece of conduit to test the adjustment. If wrinkling
still occurs, repeat the procedure.
NOTE: Both adjusting bolts MUST be in contact with the bender
frame. See Figure 15 on page 8.
