The shearing blades are reversible and
interchangeable; when the edges dull,
rotate them to the new edge, as follows:
1. Remove hold-down by loosening
screws (O, Figure 10), using 6mm hex
key.
2. Raise upper blade to highest position.
3. Remove seven screws (P, Figure 10)
and carefully remove blade.
4. Rotate or replace blade and re-install
screws (P).
5. Re install hold-down. When blade is in
highest position, the gap between the
hold-down and the table should be within
1/4. Adjust to this position by turning the
two screws (O, Figure 10) as needed.
When the blade starts its downward travel,
the hold-down should immediately hold
workpiece in place.

Slip Roll set-up
Do not roll material larger
than 30
”
20-gauge mild steel. The slip
roll guard must cover the rolls except
when material is being fed into the
rolls. Failure to comply may cause
serious injury and/or damage to the
machine.
Material Size Considerations
To determine approximate length of
material needed for a desired size tube,
use the following formula :
C
=
πD
Where
C
is the circumference,
π
equals
3.1417 and
D
is the diameter.
For example: To find the length of
material needed (C) to form a tube 4" in
diameter, multiply 3.1417 by 4". Result:
12.5667" is the circumference of
approximate length of material needed.
Cut several pieces of material to this
length for a forming test run. Material may
have to be lengthened or shortened
depending upon results of test run.
TIP:
If it doesn’t interfere with the
proposed final shape or design, a slight
bend made with the press brake on the
leading edge will simplify the initial rolling
