Cutting bit and double bit keys
NOTE: check that the carriage is locked into the fi xed horizontal position (chap. 5.1).
1) Fit the keys into the clamps (original key in the left-hand clamp and key blank in the right-hand clamp) with the
bit up against the stop (Y) (Fig. 26).
2) Close the clamps with handles (J1) making sure that the key shafts are in the V groove and check that the key
bits are perpendicular to the tracer point and cutter (Fig. 24).
3) Activate the tilting carriage mechanism (chap. 5.1).
4) Turn on the machine with the switch (H).
5) Use the lever (A) to slowly take the carriage towards the cutter and press the switch (K) to start the motor.
6) Hold the handle (B) slightly raised with the key facing downwards.
7) Take the cut closest to the original key tip against the tracer point and lower the handle (B) to round off the cut.
8) Take the carriage back to come out of the cut. Move the carriage sideways and enter the next cut (Fig. 25). Do
not move sideways once into the cut.
9) Complete all the bits in the same way and remove any excess material at the end of the cutting operation
(towards the head).
10) Take the carriage all the way back.
11) Turn off the switch (K).
12) For double bit keys, turn both keys over and repeat the operations described above.
