OPERATING PROCEDURES
GENERAL CAUTIONARY IMPORTANT WARNINGS
Electrabrake machines are designed for ONE operator only, which includes the inserting the sheet
metal and operating the switches.
See specifications for clamping strength – please note that the force is several tonnes. All units are
fitted with a two-handed interlocking system to prevent hands being accidentally trapped when
clamping.
Safety procedures:
1. Safe pre-clamping is engaged
2. Full clamping is activated
3. Lower clamp bar to 5mm of the bed
4. Magnet will engage
STANDARD BENDING
Preparation: Switch on power. Check that the clamp bar is correctly positioned and that locating
pins are in place at each end of the clamp bar.
For bigger models EB-2000, EB-2500 and EB-3200
Should lifting pins be locked – locate handles below the machine, push hard back and release
forward to lift the clamp bar slightly.
Set the machine to suit the sheet metal thickness by rotating the 2 screws situated on the
back edge of the clamp bar. Check the clearance by lifting the bending beam at 90 deg. and
examine the gap. To achieve and perfect bend, set a fractionally larger gap, than the depth
of the sheet metal, between the edge of the clamp bar and the face of the bending beam.
Place sheet metal under clamp bar – the backstop can be used if needed.
Lift handles or push down the clamp bar onto the sheet metal. The machine will not turn ON
until the clamp bar is within 5mm above the surface bed due to the interlock. The interlock
can be operated by locking down the lifting system if the clamp bar is unable to be lowered
to 5mm. This can occur when sheet metal is buckled.
To apply pre-claming force use the foot-switch or depress and hold any of the green start
buttons.
To activate the micro-switch for full clamping, pull one of the bending handles with your free
hand. Release footswitch or start button.
Pull on both handles and begin bending till the angle required is achieved. Assistance will be
necessary when carrying out heavy duty bending. The right handle has a beam angle, which
graduates continuously. To allow for spring back of the sheet metal, bend a few degrees
more than the angle that is required.
The electrical circuit of the machine releases a reverse pulse at the OFF stage allowing the
clamp bar to release immediately.
