For your own safety, read the owner’s manual before operating the hand brake.
This hand brake is designed and intended for use by properly trained and experienced personnel
only. If you are not familiar with the proper and safe operation of a hand brake, do not use until
proper training and knowledge have been obtained.
1. KEEP GUARDS IN PLACE and in working order.
2. KEEP ALL BODY PARTS AWAY FROM MOVING PARTS. Avoid placing any part of your body
near belts, cutters, gears, etc.
3. DO NOT EXCEED RATED CAPACITY on this hand brake.
4. KEEP THE WORK AREA CLEAN. Cluttered areas and work benches invite accidents.
5. KEEP CHILDREN AWAY. All visitors should be kept a safe distance from the work area.
6. MAKE THE WORKSHOP KID PROOF with padlocks, master switches, or by removing starter keys.
7. DON’T FORCE THE MACHINE. It will do the job better and more safely at the rate for which it was
designed.
8. USE THE RIGHT MACHINE. Don’t force a machine or attachment to do a job for which it was not
designed.
9. WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other
jewelry which may get caught in moving parts. Non-slip footwear is recommended. Wear protective
hair covering to contain long hair.
10. ALWAYS USE SAFETY GLASSES. Also use face or dust masks if the cutting operation is dusty.
Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.
11. DON’T OVERREACH. Keep proper footing and balance at all times.
12. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for the best and safest performance.
Follow instructions for lubricating and changing accessories.
13. NEVER STAND ON A MACHINE. Serious injury could occur if the machine is tipped.
14. 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.
15. SHEET METAL STOCK HAS SHARP EDGES. To prevent cuts, use caution when handling.
16. KEEP HANDS AND FINGERS clear of the area in front and rear of the brake.
17. DO NOT USE THE MACHINE for any purpose other than for which it was designed.
18. FAILURE TO COMPLY with all of these warnings may cause serious injury.
19. SOME DUST CREATED BY power sanding, sawing, grinding, drilling and other construction
activities contains 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 and cement and other masonry products, and
•Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures 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 those dust masks that are specifically designed to filter out microscopic particles.
20. DO NOT OPERATE TOOL while under the influence of drugs, alcohol or any medication.

Uncrating and Clean-Up
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 work bench, and
secure to the bench with lag screws or bolts.
6. Machine location must allow access to all
sides.
Brake Setup
The brake will not bend properly if it is not level.
Use a machinist’s level and shims if necessary.
Apron Adjustments
The (#) in the text refers to the breakdown.
The apron assembly has been adjusted at the
factory for proper use of capacity material.
During shipment of this unit the machine may
have come out of alignment.
The forward edge of the holddown (66) should
be adjusted parallel to the pivot edge of the
clamp block. Release clamping pressure on the
holddown assembly by pushing clamp handles
slightly to the rear. Turn the hex cap screws (64)
to adjust for parallel.
The center of the apron can be adjusted by
tightening the truss nut on the apron assembly.
Operating the Brake
Adjusting for Metal Thickness:
The hold-down assembly 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 hold-down
(66) should be adjusted parallel to the pivot
edge of the clamp block. Release clamping
pressure on the hold-down assembly by pushing
clamp handles (42 & 43) slightly to the rear.
Turn the hex cap screws (64) to adjust for
parallel and proper clearance. The center of the
hold-down can be adjusted by tightening the
truss nut on the hold-down assembly.
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 clamping
handles. Clamping pressure can be adjusted by
turning the lower nuts (54) on the threaded rod
portion of the yoke assembly (48).
Flange Capacity:
The recommended minimum flange in capacity
material is one inch.
Repeat Bends:
Adjust the stop (81) on the stop rod (69) to limit
the swing of the apron assembly.
Counter Weight:
The counter weight (68) can be moved up or
down to provide more or less leverage
depending on the material.
Lubrication
The machine must be lubricated every day of
service with a few drops of oil. Oil pinholes are
located at both yoke assemblies (47 & 48), and
the apron assembly near the hinge pin (53).
Lightly oil the machined parts when not in use to
prevent rust.
