4. Press the GREEN power rocker switch to ON.
5. Position the piece part under the clamp bar. Use the backstop if needed.
6. To apply the pre-clamping force, step down on the footswitch or press either of the GREEN
start switches (See fig. 8 below).
7. Now that the piece part is held in place, pull up on the bending leaf handles. This will activate
the micro-switch which tells the electro-magnet to apply full clamping force. Continue pulling
up on the handles until the desired bend angle is made.
8. The left handle has a leaf angle indicator that is shown in (fig. 9).
To allow for springback of the material, bend a few degrees more
than the required angle. Read the section Understanding
springback. There is also a locking collar on the indicating shaft
which can be set and locked to duplicate multiple bends.
9. After the bend is made, lower the bending leaf. DO NOT ALLOW
THE BENDING LEAF TO SLAM BACK TO THE LOWER
POSITION!
10. Press and HOLD IN the RED stop button (fig. 10) until the clamping
bar releases. Release the red button.
Important:
Each time the machine switches OFF, a short
pulse of reverse current is sent through the electromagnet to
demagnetize it as well as the piece part. Holding the red stop button
for 2-3 full seconds help collapse the magnetic field.
11. Reposition the piece part for the next bend and repeat steps 4 thru 7.
12. For thicker gauge materials set the toggle switch in (fig. 10) to the
CLAMPING FOR BENDING position. When bending very thin materials
set the toggle switch to CONTINUOUS LIGHT CLAMPING.
