Mittler Bros Machine & Tool 2800 Straight Brake - Manual (Page 7)

- 7 -
PRINCIPLES OF OPERATION
Clamp Pressure: Pressure applied with Upper Clamp Head.
NOTE: Apply only enough clamp pressure to hold the metal from moving or slipping.
Set Back: Distance Front Edge of Upper Pinch Head is back away from Apron Pivot point.
General Rule:
18 Gauge (0.050”) or less metal thickness = 1-1/2 times the material thickness.
16 Gauge (0.060”) or more metal thickness = 2 times material thickness.
PRECAUTIONS:
1) Read and understand the safety instructions on page 3 of this manual before proceeding.
2) Always adjust the set back clearance and clamping pressure for different thicknesses of material.
3) Always bend short pieces of material in the center of the brake in order to equalize the stress and
avoid damage to the brake.
4.) Do Not bend rods, nails, or wire in Brake. This will damage the clamp finger(s) and apron.
5.) Do Not bend hems or seams unless the clamp pressure adjustment is changed to handle the extra
(double) metal thickness.
6.) Use your legs and arms when making bends, similar to lifting heavy objects, to avoid back strain.
