REFER TO SECTION 6.2A FOR SHEAR BLADE ADJUSTMENT.
REFER TO SECTION 6.2B FOR SHEAR ARM ADJUSTMENT.
FIGURE 7A
THE BASIC METHOD OF OPERATING THE BAR SHEAR CONSISTS OF THE FOLLOWING
STEPS:
1. Place the material to be sheared between the shear blades.
2. Adjust the hold-down device down until it is 1/8 of an inch above the material to be sheared.
REFER TO SECTION 6.2A. This prevents "kick-up" of the workpiece and possible damage to
the machine.
3. DEPRESS THE FOOT PEDAL.
Lubricating oil should be applied to the blades every 10 to 15 cuts.
IN ADDITION TO THE FIVE BASIC STEPS OF OPERATION, THE OPERATOR SHOULD ALSO
BE FAMILIAR WITH THE FOLLOWING:
MAINTAIN PROPER BLADE CLEARANCE.
The quality of the cut is an immediate indication of the condition of the shear blades or the amount of
clearance between the blades. For adjustment procedures, REFER TO SECTIONS 6.2B.
RECOMMENDED CLEARANCES FOR FLAT BAR SHEAR BLADES:
Blade clearance is factory set to 0.020" (0.51 mm) .
DO NOT SET CLEARANCE LESS THAN 0.005" (0.13 mm).
For material thickness or blade clearances outside of this chart, consult dealer or factory.
