On the Model 1016 brake
also loosen the apron stiffener adjusting nut
located behind the lower apron tensioning adjusting nut (see Figure 12).
2.
Loosen the upper and lower beam tensioning screws (see Figure 9).
3.
Raise the upper beam to its maximum open height

Check the top edge of apron in relation to the top surface of the bed. The
top edge of apron must be 1/64-in. below the top surface of the bed at each
end. If not, loosen the hinge bolts and adjust the apron up or down using
the apron jack screws (see Figure 13). After the apron edge is adjusted to
the proper position, be sure to retighten the hinge bolts.
5.
Tighten the apron stiffener adjusting nut until the apron edge is 1/32-in.
above the bed edge at the center (see Figure 12). The apron edge should
remain 1/64-in. below the bed edge at both ends.
