Lifting handles are attached to end of the brake so two men can lift and move the
brake where it is needed. Once the brake is where you want it set it down, unhook the
chains from the c-hooks and lift the brake. The legs will unfold into place. NOTE:
ensure the leg are fully opened and on level ground.
Install the Stand Locking Bolts (P/N 422005) Find number (5) in four places and
tighten securely.
Pushing the clamp handles toward the rear of the brake lifts the ram from the bed and
apron. Insert the material to be bent into the opening between the ram and bed
assembly and clamp the material in place by pulling the clamp handles forward. Raise
the apron to bend the material to the desired angle.
Allowing for metal thickness - The ram assembly must be adjusted to allow for
clearance when making bends according to the thickness of the material being
formed. This adjustment is made by slightly releasing the clamping pressure on the
clamp handles and moving the forward edge back, away from the edge of the clamp
block on the bed. This movement is accomplished by loosening the bracket lock bolts
(Find Number 5) one on each end of the bed assembly. For 22 gauge materials allow
a clearance equal to twice the thickness of the material being worked. For lighter
gauges, allow a clearance equal to one and one half times the thickness of the
material. A larger bend radius can be accomplished by increasing the clearance.
Clamping pressure – Clamping pressure should be adjusted according the thickness of
the material being worked. A common cause of bending and forming problems is
excessive clamping pressure. 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. Clamping pressure is adjusted by turning the nuts on the threaded rod
portion of the yoke assembly below the clamp swivel. The lift of the ram assembly is
adjusted by turning the nut above the clamp swivel. When the clamping pressure is
properly adjusted, lock the nuts against the clamp swivel to prevent any change in
adjustment.
Capacity – The capacity of the brake is 22-gauge mild steel.
