C.Angle Adjustment
To adjust Brake for bending clearance, raise folding blade 90 degrees, insert
material between edges of folding blade and leading edge of fingers (for heavy
material, clearance should be twice the thickness, less for lighter gauge or if
sharper bend is desired). Adjust finger mount weldment by turning arm
adjustment bolts (item 45). To adjust clamping pressure, insert material under
fingers and turn arm adjustment bolts until material is held securely when
fingers are lowered. To adjust degree of bend, pins (item 47) located on both
ends of folding blade for desired degree of bend.
Reverse Bends
Remove the five Hex head cap screws 3/8-16x1 (item 18) the support bar (item
38) and adjust Brake as shown.
NOTE: 16 GAUGE CAPACITY (with support bar in place)
MINIMUM LENGTH OF BEND WHEN
FORMING A REVERSE BEND = 1/4
NOTE: Di-Acro Brakes are rated for 1” minimum flange when bending full
capacity. Caution should be used if necessary to bend heavier gauge material in
short widths.

D. MICROMETER BACK GAUGE
Typically the back gauge is assembled when the finger brake is shipped from
the factory. Occasionally it is removed for ease of palletizing. To install and/or
zero the gauge follow the instructions below. (Refer to parts breakdown pages
5.6,7)
1. Install quik set rod (item 49) in holes located in rear of the base casting.
2. Hold quik set dial assemblies (items 55, 56,57) on zero and screw rods in
until gage (item 51) lines up with folding blade. Quik set rods can be
locked in place by tightening screws located behind folding blade.
3. To position micrometer back gauge rapidly, turn quik set dial assemblies
to zero. Depress dial and slide complete back gauge assembly to desired
position. For fine adjustment turn quik set dial assemblies in regular
manner.
