CAUTION
To prevent damage to the follow bar,
be sure the follow bar is inserted
tapered end first and rests against
the “U” strap. When installing the follow
bar, the numbers engraved into the
bar must face up.
5. If the follow bar will not fit between the roller
assembly and the conduit, the rollers will have to
be moved. Turn the pump on. Press the “Retract”
button momentarily to move the rollers back.Turn
pump off. Push follow bar into position against the
“U” strap.
6. Prior to pressing the advance button, hold the end
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.

", 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 2

anchor pin through the top frame, cylinder block
and lower frame. Figure 26.

CAUTION
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 3

"–4" holes of the upper frame.
Figure 28.

2. Position the bending shoe (numbers facing up) on
the lower roller plate. Install the upper roller plate
assembly. Be sure the lower roller axles are flush
with the top of the upper roller plate.
3. Place the upper frame on the cylinder block so the
lock tab and the roller axle are located in the
center groove of the frame. Position the hole (in
the far end) over the pin hole in the bending shoe.
4. Insert the bend shoe pin (BZ78) through the upper
frame, bend shoe and lower frame. Insert the
retaining pin into the hole at the bottom of the
bend shoe pin. Figure 29.
