12. Rotate the work lever to feed the sheet metal
through the rollers (Figure 9 ). Often after
the first feed is made, an initial flat is cre-
ated (Figure 10) at the leading tip of the
workpiece.

Flat
13. To remove this flat, rotate the workpiece and
feed it in from the tail end this time (Figure
11). This step may have to be repeated a few
times depending on the final radius required.

14. In small increments, tighten the radius adjust-
ment knobs for each and every subsequent
pass until the needed bend radius or cylinder
diameter is reached.
Note: To create cones, adjust the rear roller
on one end only.
15. To remove a cylinder, loosen the thickness
adjustment leaf bolt, and rotate the lock leaf
pin so the flat in the pin (Figure 12 ) allows
the end of the top roller to be removed.
16. While you hold the end of the roller outward
(Figure 12 ), and the other end is pressed
in the machine, have an assistant slide the
cylinder off. The roller is heavy, so do not try
this alone.

We recommend getting assistance to sup
port the top roller while removing cylin
ders. Failure to adequately support the top
roller may result in the roller falling, causing
crushing injuries.
