READ INSTRUCTIONS
• Thoroughly read and understand this manual before using.
• Save for future reference.
PINCH AND CRUSH HAZARD!
• The Eastwood Press Brake Attachment consists of moving components
that quickly generate extreme crushing force which can present a hand/fin-
ger pinch hazard and cause potentially serious injuries. Avoid pinching hands
while handling. Keep fingers and hands away from moving parts
when operating.
CUT HAZARD!
• Handling sharp metal can cause serious cuts. Wear thick, well-fitting
work gloves to prevent cuts from handling sharp metal.
EYE INJURY HAZARD!
• Metal particles can be ejected from the metal surface when bending.
Sheet metal edges and corners are sharp and can injure eyes.
Always wear ANSI approved eye protection when operating this tool.
DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.
WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION used with the safety alert symbol, indicates a hazardous situation which, if not avoided,
could result in minor or moderate injury.
NOTICE is used to address practices not related to personal injury.
SAFETY INFORMATION
The following explanations are displayed in this manual, on the labeling, and on all other information
provided with this product:

• Before beginning ANY work with this tool, it is absolutely necessary that it be
mounted in a properly sized 12 to 20 ton hydraulic press which is securely
bolted to a sturdy workbench or anchored to the floor or wall.
• Strenuous physical force may need to be applied to the Press Brake Attach-
ment during use. Failure to ensure proper footing can quickly result in a fall
which could inflict serious personal injury or property damage. Always work
in a clean, uncluttered environment.
• Be sure there is sufficient working room around the tool to allow for safe
handling of various sizes of metal.
• Excessive resistance while operating could indicate a defect with the work-
piece material or broken or damaged Press Brake Attachment components.
To avoid injury, stop work immediately and inspect workpiece material for
nicks, dents, welds, excessive scale or remaining coatings. Clean or repair
as necessary or discard and begin with a new piece. Also inspect Press
Brake components and host hydraulic press for looseness or damage.

ASSEMBLY
• Locate the Lower Die [A] to the Base
Plate [B] with two M8 x 20 mm screws
and washers (FIG 1). Tighten with a
6mm hex key.
• Insert threaded ends of Slide Posts [C]
into holes in Base Plate [A] and secure
with two M10 Nuts and Washers
(FIG 1). Tighten with a 16mm wrench.
• Place two Release Springs [D] over
Slide Posts [C] (FIG 2).
• Slide sleeves of the Upper Die [E] over
the Slide Posts [C] (FIG 3).
• Thread four (4) M8 Set Screws into
the cup feature of the Upper Die [E].
SET-UP
The Eastwood 12” Press Brake Attachment is
designed as an accessory for use in a 12 to 20
ton hydraulic press.
• Center Press Brake over the crossbar of
hydraulic press (not included).
• Slowly draw down the ram of the
hydraulic press so that it nests within
the cup on the top of the Upper Die [E].
Secure to ram by tightening the four
Set Screws with a 6mm hex key.
Use only in a Shop Press of
20 Tons or less.

OPERATION
• Follow specific operating instructions supplied with the particular hydraulic press to be used.
• Measure and mark the desired bend line on the workpiece panel.
• Slide metal panel between the Dies lining up your pre-marked bend line with the sharp, beveled
edge of the Male Die.
• Center metal panel in Press Brake.
• Gently and slowly draw down the hydraulic ram of the hydraulic press to begin creating the
desired bend. NOTE: The use of an angle gauge or protractor (not included) is recommended.
• Depending on the particular alloy being bent, it may be necessary to push the dies slightly
beyond the desired finished angle to allow for “springback”. Some trial and error is suggested
with scrap material before making final bends.
MAINTENANCE
• Keep all areas of the tool clean particularly those surfaces that contact sheetmetal workpieces.
Dirt and metal chips can cause uneven clamping and inaccurate bends.
• Store in a clean & dry environment when not in use. Coat all machined surfaces with a light
lubricant film of oil or suitable protectant to prevent rust formation.
