7. After full extension, press the reverse foot pedal, as the drive lever retracts, the anti-
springback lock pin will hold the ratchet wheel in place. You can restart the bending process
at any tooth on the ratchet wheel or return the machine to the home position and get the
maximum degrees per stroke. Each tooth on the ratchet wheel represents approximately 7
degrees of bend.
8. If the bend requires more degrees, increase the degrees by repeating step 6 until the desired
degrees of bend is achieved. This allows the operator to gradually reach a bend angle, on
the first set up piece. Once the proper degree of bend is achieved, document the degree (ex;
98deg = 90deg bend, 8degrees of spring back) so multiple bends to that same degree can
be accomplished.
9. When at the desired degree position the drive lever can be returned to the home position.
Material Removal
1. After reaching the desired angle, the material needs to be removed.
2. Pull the anti-springback lever (clockwise) to release tension.
3. Rotate the main bending lever fully to the right or clockwise, this will free the ratchet wheel
completely. Grab the ratchet wheel and rotate counter clockwise until it stops completely,
this is the “home” or “0°” position. The degree pointer should verify this.
4. Once at the “0°” position, engage the anti-springback lever to lock the pin. Activate the quick
release counter die lever and completely remove the material.
5. The machine is now at the “home” position and can be reloaded for the next bend.
6. Repeat previous steps.
7. With the reverse foot pedal, bring the drive lever to the home position. You will hear a
clicking as the drive lever skips over the ratchet wheel. As the drive lever approaches home,
the drive shaft slides up a ramp and disengages the ratchet wheel, stopping at home. A
slight tap of the forward pedal will relieve any tension on the drive pin allowing free
movement of the ratchet wheel.
8. At this point disengage the anti-springback lock pin. This will free the ratchet wheel. Grab the
ratchet wheel and rotate counterclockwise until it stops completely, this is the “0°” or home
position. The degree pointer should verify this.
9. For another bend on the same workpiece, restart steps from step 4 above.
CAUTION:
Stand clear of the material it may spring out quickly.
