Unpacking
1. Remove the crate from around the machine.
2. Carefully clean all rust protected surfaces
with a mild solvent or kerosene and a soft
rag. Do not use lacquer thinner, paint
thinner, or gasoline. These will damage
painted surfaces.
3. Coat all machined surfaces with a light coat
of oil to inhibit rust.
4. Remove the bolts holding the machine to the
skid.
5. Carefully move the machine to a well-lighted
area on a solid, level workbench, and secure
to the bench with lag screws or bolts.
Machine location must allow access to all
sides.
Assembly
The BP-1696H does not require assembly.
However, it is important to make sure that the
machine is level; otherwise the brake will not
bend properly.
Use a machinist's level and shims if necessary.
Adjustments
The (#) in the text refers to the Item Number in
the Parts Breakdown section.
The apron assembly has been adjusted at the
factory for use with material having the capacity
as listed in the Specifications section. During
shipment of this unit the machine may have
come out of alignment.
The forward edge of the holddown fingers (1, 2,
3, 4) should be adjusted parallel to the pivot
edge of the clamp block. Release clamping
pressure on the holddown assembly (800) by
pushing the clamp handles (8, 9) to the rear.
Adjust the hex cap screws as necessary for
parallelism.
The center of the apron can be adjusted by
tightening
the
truss
assembly (803).
Finger alignment can be achieved by loosening
all cap screws (15) and rotating the apron (803)
to the 90-degree position. Push the fingers
forward against the angle bar (36) for proper
alignment. Tighten screws (15).

Operation
Adjusting for Metal Thickness
The holddown assembly (800) must be adjusted
to allow for clearance when making bends
according to the thickness of the material.
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. The forward edge of the holddown
fingers should be adjusted parallel to the pivot
edge of the clamp block. Release clamping
pressure on the holddown assembly by pushing
clamp handles (8, 9) slightly to the rear Adjust

parallelism. The center of the apron can be
adjusted by tightening the truss nut on the apron
assembly (803).
Adjusting the Clamping Pressure
The clamping pressure should be adjusted
according to the thickness of the material. The
clamping pressure should be great enough to
hold the material securely in place but not so
much that it is difficult to lock the clamp handles
(8, 9). Clamping pressure can be adjusted by
turning the nuts (24) on the threaded rod portion
of the toggle assembly (10, 11).
Flange Capacity
The recommended minimum flange capacity is
one inch.
Repeat Bends
Adjust the gauge stop (26) on the gauge rod
(31) to limit the swing of the apron assembly.
Counter Weight
The counter weights (44) can be moved up or
down to provide more or less leverage.
Lubrication
The machine must be lubricated every day of
service with a few drops of oil. Oil pinholes are
located at both toggle assemblies (10, 11) and
the apron assembly (803) near the swivel pin
(23). Lightly oil the machined parts when not in
use to prevent rust.
