It is important to occasionally clean the scale and dirt from the Ball Transfer sockets as this material may keep the
transfers from depressing when the holddown fingers clamp the material to be sheared. The height of the ball above the
surface of the shear table is adjustable (Figure 35) and should be just high enough to allow easy movement of a piece of
capacity plate across the shear table.
To adjust the height of the balls, loosen lock nut "A" (Figure 35) and turn adjusting screw "B" either to the right or to
the left depending on the adjustment required. Be sure to retighten lock nut '"A".
SQUARING ARM
Squaring Arms can be provided on any size machine in the following ranges: 72", 96", 120" and 144". Each squaring
arm is provided with a stainless steel scale and an adjustable hinged stop (Figure 36). After the lower blade has been
sharpened a number of times, it will become necessary to adjust the scale for accurate measurement. Lock screws
The screws are loosened to move the scale for adjustment.
Adjustment should always be made for accurate measurement from the cutting edge of the lower blade. Make sure the
scale in the squaring arm is adjusted at the same time as the two scales in the shear table.
The adjusting bracket is bolted to the side of the squaring arm and the front of the shear table. This is to help hold
the squaring arm in position and square with the lower blade. Assuming the squaring arm is installed on the right end of
the table, to adjust it to the left, loosen the bolt between the bracket and the table, move the arm in that direction and
retighten the bolt. To adjust to the right, loosen the bolt between the bracket and the arm and move the arm in that
direction. Place shims between the bracket and the arm and retighten the bolt. If the squaring arm is installed on the left
end of the table, the above directions should be reversed:
The squaring arm can be used on either the right or left hand side of the shear. To use the squaring arm on the
opposite side of the shear, remove the bolts from the gauge bar and move the gauge bar to the opposite edge of the
Squaring Arm. The squaring arm assembly can now be moved to the opposite end of the shear.
