6.2B SHEAR BLADE ADJUSTMENT
To set the blades, lower the arm so that the upper blade crosses the lower blade. (If fitting new or
re-ground blades, ensure that the lower blade is fully adjusted away from the upper blade before
lowering the arm.)
Switch off the machine.
Remove the shear hold-down and the shear support table.
Adjust the lower blade to the upper blade to achieve desired clearance. See Figure 14 below.
Ensure that the lower blade is adjusted with a slight cant, or tilt of a few thousandths of an inch,
so that the cutting edge of the blade is closer to the top blade.
Lock the upper blade in position by tightening the upper blade securing screws.
Check and readjust the blade setting, if necessary.
Re-fit the hold-down and the shear support table to the machine.
The upper blade has two cutting edges, whereby the lower blade has four. It is possible to replace
the shaped upper blade by a rectangular lower blade, therefore offering multi-edged economy
shearing with only a very small amount of distortion on wide bars.
