Step 1: Clamping Pressure
Check clamping pressure by clamping test strips in the brake approximately 3 or 4 inches away from
each end of the brake. Clamping pressure should be enough to keep the material from slipping during
a bend. Do Not Use excessive clamping pressure. Excessive clamp pressure causes most bending
and forming problems.
Clamping pressure can be adjusted by loosening the top lock nut and adjusting the bottom nut to
increase or decrease the clamp pressure.
Clamping pressure should be adjusted for the thickness of the material being worked. Clamping
pressure should be adequate to hold the material securely in place but not so great as to require
undue effort in locking the clamp handles.
