(Everyday eyeglasses only have impact
resistant lenses; they are not safety glasses.)
7. Before operating this machine, remove tie,
rings, watches and other jewelry, and roll
sleeves up past the elbows. Do not wear loose
clothing. Confine long hair. Non-slip footwear or
anti-skid floor strips are recommended.
8. Wear ear protectors (plugs or muffs) if noise
reaches unsafe levels.
9. Some dust created by power sanding, sawing,
grinding, drilling and other construction
activities contain chemicals known to cause
cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
•Lead from lead based paint.
•Crystalline silica from bricks, cement and
other masonry products.
•Arsenic and chromium from chemically
treated lumber.
Your risk of exposure varies, depending on how
often you do this type of work. To reduce your
exposure to these chemicals, work in a well-
ventilated area and work with approved safety
equipment, such as face or dust masks that are
specifically designed to filter out microscopic
particles.
10. Do not operate this machine while tired or under
the influence of drugs, alcohol or any
medication.
11. Remove adjusting keys and wrenches. Form a
habit of checking to see that keys and adjusting
wrenches are removed from the machine
before turning it on.
12. Keep safety guards in place at all times when
the machine is in use. If removed for
maintenance purposes, use extreme caution
and replace the guards immediately after
completion of maintenance.
13. Check damaged parts. Before further use of the
machine, a guard or other part that is damaged
should be carefully checked to determine that it
will operate properly and perform its intended
function. Check for alignment of moving parts,
binding of moving parts, breakage of parts,
mounting and any other conditions that may
affect its operation. A guard or other part that is
damaged should be properly repaired or
replaced.
14. Provide for adequate space surrounding work
area and non-glare, overhead lighting.
15. Keep the floor around the machine clean and
free of scrap material, oil and grease.
16. Keep visitors a safe distance from the work
area. Keep children away.
17. Make your workshop child proof with padlocks,
master switches or by removing starter keys.
18. Give your work undivided attention. Looking
around, carrying on a conversation and “horse-
play” are careless acts that can result in serious
injury.
19. Maintain a balanced stance at all times so that
you do not fall into the blade or other moving
parts. Do not overreach or use excessive force
to perform any machine operation.

5.3 Unpacking and cleanup
1. Remove all contents from shipping crate and
compare to the contents list in this manual. If
shipping damage or any part shortages are
identified, contact your distributor. Do not
discard packing material until brake is
assembled and operating satisfactorily.
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.
5.4 Assembly
Refer to exploded view if additional clarification is
needed for assembly.
1. Remove bolts holding leg stands and brake to
pallet.
2. Locate brake in a dry, well-lighted area with a
sturdy, level floor. Machine location must allow
room for loading and offloading stock, and
access on all sides for maintenance.
3. Use hoist or forklift to carefully lift brake onto leg
stands. Secure with M12 bolts, washers and
nuts (HP1/HP4/HP5/HP6).
Do not allow anyone
beneath the brake while moving it into
position and until it is secured on leg
stands.
4. Verify that brake is level; use shims if
necessary. Secure leg stands to floor with
appropriate fasteners, such as lag bolts (not
provided).
5. The clamp handles are shipped in lowered
position due to size constraints (thus, the
fingers will contact platform before handles
reach proper forward position). The handles
must be repositioned before operating, as
follows:
6. Remove screw, spring cover and spring (J,
Figure 3). Slide handle outward just enough to
clear stop pin, and rotate handle to a higher
position, as shown. Reinstall spring, spring
cover and screw, and tighten screw until there
is no “play” in the handle.

Figure 3
7. Install counterweight assemblies to left and
right hinges and tighten set screws. See Figure
3.
8. 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 onapron, as shownin 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.
Figure 4
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.
Figure 5
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 in apron and hold-down
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.
Figure 6
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.

7
6.4 Adjusting clamping pressure
Clamping pressure should be adjusted according to
material thickness. Clamping pressure should be
great enough to hold material securely in place but
not so much that it is difficult to lock the clamping
handles. Clamping pressure can be adjusted by
turning the nuts on the threaded rod portion of yoke
assembly (P, Figure 7).
When clamping handles are properly set, youwill be
able to feel them drop into locking position.
6.5 Repeat bends
Adjust stop collar on stop rod (Figure 4) to limit
apron swing.
7.0 User-maintenance
7.1 Lubrication
The machine must be lubricated every day of
service with a few drops of oil at the pivot points. Oil
pinholes are located at both yoke assemblies (A,
Figure 7) and the apron assembly near the hinge pin
(B).
Lightly oil all machined (unpainted) parts when not
in use, to inhibit rust.
