77.2 Unpacking and cleanupInspect contents of shipping container for shippingdamage. Report any damage to your distributor.Remove all contents from carton, and compare tothe contents list in this manual. Report any partshortages to your distributor.Do not discard carton or packing material untilmachine is assembled and working properly.Exposed metal areas may have a rust protectantapplied. Remove this with a soft rag and solventsuch as kerosene. (Do not use gasoline, paintthinner, acetone, etc., as these will damagepainted surfaces.)Contents of shipping container1 Box and Pan Brake2 Support legs with screws1 Instructions and Parts Manual (not shown)1 Warranty Card (not shown)8mm hex key required for assembly.7.3 Assembly8mm hex key required for assembly.Numbers in parentheses refer to items in Figure 1.1. Remove any straps securing the machine, andraise into position using properly rated liftingequipment. The floor must be stable and level.Continue to stabilize themachine while installing the support legs.2. Attach the two support legs (11) with twoscrews each.3. Secure machine to floor using lag screws orsimilar system. See diagram, Figure 2.8.0 OperationNumbers in parentheses refer to items in Figure 1.8.1 Adjusting setbackThe bending leaf blade (7) must be adjusted forproper clearance, or “setback” (A, Figure 3) basedon material thickness (B, Figure 3). Generally,setback for material within four gauges of capacityshould be twice the thickness of material. Forlighter gauges, use 1-1/2 times the materialthickness. Consult a machinery handbook for bendallowances.Figure 31. Loosen setback locking screws (5).2. Rotate setback knobs (6) in equal amounts(clockwise decreases distance).Note: When increasing distance (counter-clockwise), you may have to pull back slightlyon the bending leaf to take up any backlash.3. Bring the clamping leaf into position and checkthe setback.4. Repeat above steps until proper distance isachieved. Verify that bending leaf blade (7) isparallel to clamping fingers (2).5. Tighten screws (5).If a crown develops in the material, this can beadjusted out by loosening or tightening the hexnuts on the crown adjustment rod (12). Note: Thisrod has been correctly set by the manufacturer andshould only be adjusted when needed.8.2 Adjusting clamping pressureClamping pressure should be great enough to holdmaterial securely, but not so much that it becomesdifficult to clampRotate clamping adjustment knobs (3) equally toset clamping pressure.8.3 Repeat bendsAdjust stop bolt (4) to limit swing of bending leaf.
