a 14" stroke. As a result, the cylinder mounting
block must be moved to the holes in the frame that
match the size conduit being bent. Figure 15.

2. Slide the cylinder along the bottom frame until the

cylinder mounting block grooves are aligned with
the desired holes in the lower frame.

3. Position the bend shoe on top of the lower roller

plate. Be sure the bend angle numbers are
facing up. Figure 16.

4. The top plate and roller assembly are installed

over the bend shoe. Prior to installation, be sure
to move the indicator knob to either “C” for Rigid/
IMC or “T” for EMT (thinwall) conduit. Figure 17.

5. The axle for the large roller (upper plate

assembly) has two flats which engage the retainer
of the lower plate assembly. Press the upper roller
down until the lower roller axles are flush with the
top plate. The flats on the upper roller axle must
fully seat into the retainer collar. Figure 18.

NOTE: The roller assembly may not fully seat on the

first attempt. To ensure proper engagement,
move the indicator knob (slightly) until the
axles of the lower rollers are through the top
plate and flush with the top of it.

6. Move the bend shoe to align the pivot hole with

the hole at the end of the lower frame. Figure 19.
