Safety Warnings and Precautions
WARNING: When using tool, basic safety precautions should always be followed to re-
duce the risk of personal injury and damage to equipment.
Read all instructions before using this tool!
1. Keep work area clean. Cluttered areas invite injuries.
2. Observe work area conditions. Do not use machines or power tools in damp or wet
locations. Don’t expose to rain. Keep work area well lighted. Do not use electrically
powered tools in the presence of ammable gases or liquids.
3. Keep children away. Children must never be allowed in the work area. Do not let them
handle machines, tools, or extension cords.
4. Store idle equipment. When not in use, tools must be stored in a dry location to inhibit
rust. Always lock up tools and keep out of reach of children.
5. Do not force tool. It will do the job better and more safely at the rate for which it was in-
tended. Do not use inappropriate attachments in an attempt to exceed the tool capacity.
6. Use the right tool for the job. Do not attempt to force a small tool or attachment to do
the work of a larger industrial tool. Do not use a tool for a purpose for which it was not
intended.
7. Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving
parts. Protective, electrically non-conductive clothes and non-skid footwear are recom-
mended when working. Wear restrictive hair covering to contain long hair.
8. Use eye and ear protection. Always wear ANSI approved impact safety goggles. Wear
a full face shield if you are producing metal lings or wood chips. Wear an ANSI approved
dust mask or respirator when working around metal, wood, and chemical dusts and
mists.
9. Do not overreach. Keep proper footing and balance at all times. Do not reach over or
across running machines.

mounting xtures; and any other condition that may affect proper operation. Any part that
is damaged should be properly repaired or replaced by a qualied technician.
13. Guard against electric shock. Prevent body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerator enclosures.

Assembly and Operating Instructions
The 30” Bending Brake requires some minor assembly as described below. Please refer to the
parts diagram on page 5 and the part number listing shown below when reading these instruc-
tions.
The Stand (#1) should be secured to a work bench using the mounting holes and 4
bolts (3/8” diameter).
Each Handle Ball (#7) should be attached to the Handle Lever (#6) and the Handle
Levers should be placed into the Handle Sockets (#5). The Handle Levers are not de-
signed to be permanently mounted into the Handle Sockets.
To use the Bending Brake, lower the Handle Lever until the Moving Plate is parallel to
the work bench. Position the material to be bent on the Supporting Plate (#2) and the
Moving Plate and properly align with the edge to be bent up against the back edge of
the Supporting Plate.
Place and secure the Pressing Plate (#3) on top of the Supporting Plate with the back
edge of Pressing Plate aligned with back edge of Supporting Plate.
Note: To insure a proper bend, leave a 1/8” gap for 18 gauge material. For thicker ma-
terial, this gap will increase. It is suggested that you bend a scrap piece of material rst
to verify the correct material position. It is also recommended that the material be held
in place with C-clamps or other appropriate holding devices.
Raise the two Handle Levers to bend the material to the desired angle.
WARNING! When using the Bending Brake keep ngers clear of the Supporting Plate
and Moving Plate to avoid personal injury.
When the Bending Brake is not in use, it should be covered and stored in a dry location.
