Install counterweight assemblies to left and
right hinges and tighten set screws. See Figure

Install handle (B) and center brace (C) to front
of apron (HP1, HP4,HP5).
9.
Install stop rod assembly on left side of brake,
through weldment on apron, as shown in Figure
4. Secure stop rod pin (F) with flat washer and
hex nut (HP7,HP3). Install cotter pin (HP8) at
end of stop rod, and bend with pliers to secure.

6.0 Adjustments
6.1 Counterweight position
Proper counterweight position determines amount
of leverage for the bend, and most efficient
movement of apron for the operator.
Adjust counterweight by backing out screw (K,
Figure 5) and rotating upper and lower collars (L) as
needed. When counterweight is at desired position,
turn screw (K) until it re-engages counterweight.
6.2 Apron adjustment
The apron assembly has been adjusted by the
manufacturer for use with material having the
capacity listed in the Specifications section. If any
misalignment occurs, correct as follows.
The forward edge of hold-down fingers should be
adjusted parallel to pivot edge of press bar. Release
clamping pressure on hold-down assembly by
pushing clamp handles slightly to the rear. Turn
knobs (M, Figure 6) to adjust hold-down assembly
for parallel.
The truss nuts (N, Figure 6) can be used to help
achieve
alignment
assemblies, by eliminating any bowing at the center
of these assembles.
Finger alignment can be achieved by loosening the
cap screws on the fingers and raising apron to 90-
degree position. Push fingers forward against apron
bar for proper alignment. Retighten all screws.
6.3 Adjusting for metal thickness
The hold-down assembly must be adjusted to allow
for clearance when making bends according to
material thickness. Clearance for material within
four gauges of the capacity should be twice the
thickness of the material. For lighter gauges use 1-
1/2 times the thickness.
Turn both knobs (M, Figure 6) the same amount to
maintain parallelism of fingers with apron.
