Braking
For precision braking from 2'' to 10'' lengthwise,
first attach the back measurement assembly to
the receiver holes in the back of the crossbeam:
1. To adjust the position of the back measure-
ment assembly, first loosen the two knobs.
2. Move the assembly forward and back using
the handwheel. When it is at the desired
position, tighten the knobs to lock it into posi-
tion.
3. Using the handle assembly, raise the cross
beam up to its highest position.
4. Insert the workpiece in between the upper
and lower braking dies.
5. Rotate the handle assembly, using the
appropriate amount of force to achieve the
desired bending angle.
6. To bend only certain portions of your work-
piece, simply loosen the bolts that hold the
upper braking die brackets in place and add
or remove the dies as required. For small
increments, use the fractional dies included
with the machine. You should notch the
material appropriately before bending to
achieve the good results. This means you
will have to make a cut between the portion
of the material to be bent and the portion you
wish to remain straight.
The upper braking dies may become uneven.
This is best handled with a wooden gauge block
that is the full length of the table and is the same
height all the way across. Raise the crossbeam
all the way and slide the block underneath the
dies. Loosen the bolts that hold the upper die
bracket in place and allow the dies to drop slight-
ly until they contact the block. Tighten the upper
bracket bolts.

Rolling
In order to do rolling operations, move the cover
back and out of the way.
1. Drop the rear roll bar by loosening the adjust-
ment knobs.
2. Insert just the leading edge of the workpiece
between the upper and the lower roll bars,
and tighten the roll bar gap adjustment keys
until the roll bars are barely snug against the
workpiece.
3. Advance the adjustment knobs as much as
desired depending upon the tightness of the
roll to be accomplished. The tighter the roll,
the more the knobs should be advanced.
4.
Rotate the handle assembly until the proper
roll has been achieved. The material will feed
itself through the rollers as the handle
assembly is cranked.
Wire rolling is accomplished in the same manner,
except the proper groove in the upper roll bar
must be utilized depending upon the wire gauge
being rolled.
Lubrication
Grease the crank arms as necessary using a
grease gun on the installed grease fittings. Do not
over-grease.
A light coating of oil on the area where the upper
arm slides will also assure ease of movement.
