Cutting operations
ATTENTION: to work in complete safety, pay special attention to the following recommendations:
-
Always work with dry hands.
-
Check that the machine is properly earthed.
-
Use the protective goggles, even if the cutting tool is fitted with a protective shield.
-
Start the motor (switch N) only when all the operations with the carriage have been car-
ried out (securing keys, etc.).
-
Keep hands away from the cutting tool when in motion.
6.3
Use of the tracer point spring
The spring movement facilitates the identification of the cutting space before the cut is made.
-
To activate the tracer point spring:
release the tracer point spring locking knob (I3).
-
To lock the tracer point spring:
push the tracer point all the way up and secure with the spe-
cial knob (I3) (fig. 14). Use of the tracer point spring is recommended for the cutting of male
and female bit/double bit keys.

Cutting male bit and double bit keys
1) Align the mobile clamp (cutting tool side) by means of the carriage locking knob (D2) (fig. 16).

3) Place the original key into the clamp (E) on the tracer point side, pushing up against the centring
device.
4) Push the key into the centring device so that the bit butts against the stop (fig. 16).
5) Secure the key in this position by tightening the knob (E1).
6) Place the key to be cut in position by repeating steps 3, 4, 5, in that order.
7) Take the head stop (H) up against the key to be cut and lock the knob (H1).
8) Lock the centring device knobs (G2) to avoid vibrations.
9) Release the carriage by means of the knob (D2).
10) Turn on the key-cutting machine by means of the motor ON switch (N).
11) Take the carriage up to the tracer point and cutting tool by raising the carriage lever (A).
12) Grip the lever (B), turn upwards to avoid the cutting tool coming into violent contact with the bit
and cut the tooth.
13) Rest the tracer point properly on the bottom of the cut and round off the cut by moving the
carriage up and down.
14) Repeat this operation for all the cuts on the bit.
15) It is advisable to rectify the side of the key opposite the stop (fig. 15)
