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 18.
NOTE: “Stub-Up” and “Offset” dimensions can be found on
the bending charts on pages 8 to 9 of this manual or on the
bending instruction decal on the top of each Bender.
3. Rotate the bending shoe 5 to 10 degrees below the
0 degree setting. See Figure 14.
4. After marking the conduit, place it into the Bender. See
Figure 19. 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 19.
NOTE: The appropriate size and type of support roller MUST
be used with the corresponding shoe size and type.
5. Step on the “Engaging Pedal” which will raise the proper
rollers to come in contact with the conduit. See Figure 19.
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
assembly 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.
See Figure 20.
NOTE: Due to springback in pipe/conduit, some overbending
is necessary to achieve the desired degree of bend. See
page 8 and 9, or the bending instruction decal on top of each
Bender for approximate springback compensation figures.
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.
Note that 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”.

" & 2" EMT
AND IMC SUPPORT ROLLER UNITS
The B2555 Sidewinder
®
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.
1. If wrinkling occurs, pressure against the conduit during the
bending process must increase. To increase the squeeze
(pressure), loosen both sets of 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 22.
2. If side marking occurs, or loading IMC or EMT is a
problem, pressure against the conduit during the bending
process must be decreased. To decrease the squeeze
