Hole-punching
Work only with sharp punches and dies.
Oil the punch slightly to simplify pulling back.
1. Set the basic device switch to Punching.
2. To punch holes, take the bending die and the electrical angle reader from the work block.
3. Use the stamp with the Neoprene deflector and pressure plate (up to 14 mm diameter) for the working block's
mounting hole.
4. Fix the punch socket with the threaded pin opposite the height display. Use the keys supplied for this.
5. Mark the position of the slot on the busbar.
6. Place the operating cylinder in the centre of the hole punch with the help of the counting mechanism.
7. Insert the centring tip of the punch into the punch mark. This allows the hole pattern to be punched to be produced
with precision.
8. After the process has ended the hole punch returns to its initial position.
