Sample should now be held firmly in position. To adjust for more or less clamping pressure, move Clamping Lever to
unlocked (up) position, and adjust the Clamping Lever Turnbuckles as necessary to achieve firm clamping pressure.
THICKNESS OF MATERIAL ADJUSTMENT:
3. Ensure the Upper Beam is lowered to the normal operating position (but not clamped tight against the Lower
Beam). By turning the two hand knobs (18), set the Upper Beam Jaw back from the Lower Beam Jaw to accommodate
the thickness of the material to be bent. Sometimes, it may be necessary to tighten the Collar Stop Nuts (24) to prevent
creeping of the Upper Beam.
ADJUSTMENTS-FINE ALIGNMENT:
(1.) A sample work piece, the entire length of the brake, should be clamped in place. Make a test bend by lifting the
Apron a full 90. Release metal from brake Jaws and check for straightness.
(2.) ADJUSTMENTS FOR BOWING: Refer to figure 3 for location of Truss Nuts.
PROBLEM:
Bows up.
SOLUTION:
