INTRODUCTION
ELECTRABRAKE machines use an electromagnet, rather than a mechanical, clamping system.
The machine consists of a long electromagnet with a steel clamp bar located above it. The sheet
metal is clamped between the two by an electromagnet capable of clamping with a force range of
between 3 - 10 Tons. Rotating the bending beam then forms the bend. The sheet is bent around
the front edge of the clamp-bar.
Using the machine is simple, slide the sheet in under the clamp-bar; press the start-button to
initiate clamping; lift the handle to form the bend to the desired angle; and then return the handle to
automatically release the clamping force. The folded sheet can now be removed or repositioned
ready for another bend.
The special centre less compound hinges, are distributed along the length of the bending beam
allowing bending loads close to where they are generated.
The combined effect of the magnetic clamping with the special centre less hinges means that the
ELECTRABRAKE is a very compact, space saving, machine with a very high strength-to-weight
ratio.
ELECTRABRAKE EB625, EB1000, EB1250, EB 2000, EB 2500 & EB3200
The ELECTRABRAKE EB625, EB1000, EB1250, EB2000, EB2500 & EB3200 are highly versatile
sheet metal folding machines used to bend mild steel and aluminium sheet metal. Thicknesses of
up to 1.2 mm thick can be folded on the EB3200, across the full length of the machine. The
EB625, EB1000, EB1250, EB2000 and EB2500 machines fold material of up 1.6mm thickness.
These multi-purpose machines bend sheet metal of lengths 625mm, 1000mm, 1250mm, 2000mm,
2500mm and 3200mm respectively.
The ELECTRABRAKE magnetic clamping system replaces the bulky clamping structure used in
conventional folding machines. The small compact clamp bar does not hinder or obstruct the work
piece. Automatic electromagnetic clamping and unclamping, means faster operation. These
machines have a much greater versatility than conventional sheet metal benders. The machines
are ideal for use in industry, air-conditioning and building industries.
For the EB-2000, EB2500 and EB3200 an electrical interlock is offered to enhance Operator
Safety. This operation ensures that a safe pre-clamping force must be applied before full-
clamping can be engaged.
ACCESSORIES
Adjustable backstops, storage tray and a complete set of short-length clamp-bars are included as
Standard Accessories.
A foot switch is supplied as a standard accessory on the EB2000, EB2500 and EB3200 only. On
the EB1250 the foot switch is an optional extra.
A narrow clamp bar, a slotted clamp bar for forming shallow boxes more quickly and a power
shear with guide for straight distortion-free cutting of up to 1.6 mm thick is all available as Optional
Extra Accessories.
A Full 12 month warranty is offered that covers faulty materials and workmanship.

SAFETY PRECAUTIONS
Please note: no person with a pacemaker should be closer than 6 FOOT OR 1.828 METRES to
an Electramagnetic machine or anything that has an electrical field.
1. Strong electromagnetic fields can cause electromagnetic interference.
2. EMI can stop the pacemaker from sensing your heart’s rhythm.

ASSEMBLY
HOW TO ASSEMBLE YOUR ELECTRABRAKE
The EB625, EB1000
Note: The machine is supplied upside down for assembly purposes.
1. Remove all parts from the crate with the exception of ELECTRABRAKE magnet body
assembly.
2. Use the 6mm Allen Key and the screws supplied.
3. Place packing between the body and the crate.
4. Attach the feet to the column using the eight M10 x 16 button-head screws provided. Note
that the seam on the column is at the back and the two feet with the yellow and black safety
tape are the front feet.
5. Fasten the foot plate under the front feet using the M10 x 16 cap-head screws with washers.
Alignment is easier if the foot mounting is not tightened until the foot plate is fitted. The rear
feet cap head screws can be adjusted to level the machine.
6. Place the stand on its feet in a safe area so that the magnet body can be fastened to the
stand.
7. Place the magnet body on the stand securing it with two M8 x 16 cap head screws. This
would be best of you used a lifting device or got some assistance. Ensure that the magnet
wires are guided down the column as the magnet body is lowered onto the stand.
8. Remove the rear access cover to gain access to the electrical unit. By removing the four pan
head screws. Connect the adjoining matching plug leads from the magnetic coil and PC
board. Refit the rear access cover.
9. On the EB625 the tray is in two halves. First join the two halves of the tray using the two M6
pan head screws and nuts. Now using two M8 x 12 cap head screws attach the tray to the
back of the magnet body. Place the rubber mat in the tray. Attach the back stop slides to the
side of the tray.
10. On the EB1000 use four M8 x 12 cap head screws to attach the two back stop bars to the
back of the magnet body
11. On the EB1000 use three M8 x 12 cap head screws to attach the tray to the back of the
magnet body between the two back stop bars. Place the rubber mat in the tray.
12. Open the bending beam to gain access to the back of the bending beam so that you can
attach the handle.
13. Slide the handle through the angle indicating ring. Now using two M8 x 16 cap-head screws
to attach the handle to the bending beam.
14. Use solvent i.e. turpentine or methylated spirits to remove the clear protective coating from
the top of the unit and the clamp bar.
15. Place the clamp bar on the magnet body.
16. To obtain excellent results follow the operating instructions.
