3.2 Key duplication
ATTENTION: In order to work in complete safety during
the different phases of duplication, follow these ins-
tructions:
Work with dry hands.
The cutter guard should be in place whenever duplicating.
Use protective glasses.
Make sure that the machine is earthed.
Keep hands away from the milling cutter when it is
moving.
Only switch on the machine when operations invol-
ving the carriage have been completed (securing key
in the clamp, etc.)
3.2.1 Key duplication
Insert the original key in the left-hand clamp, kee-
ping it 2 or 3mm from the edge of the clamp. See
figure no.4.
Tighten the clamp, making sure the back of the key
is resting properly on the base of the clamp.
Position the uncut key to be duplicated in the right-
hand clamp and before tightening the clamp raise
the gauge (C) and align the two keys, making sure
that the two gauge pointers are resting firmly up
against the upper shoulder of both keys. Finally,
tighten the clamps.
See figure 9
Both the original key and the uncut key to be
duplicated should be inserted in the respective
clamps from the left hand side.
Start the machine, and supporting the carria-
ge by means of the lever (M) move the keys
towards the tracer point (I) and the milling
cutter (F), pressing the button (P). The gauge
(C) automatically withdraws when the carriage
moves forward towards the tracer point and
the milling cutter.
Do not forget that it is necessary to work from
left to right. Rest the original key against the
tracer point and begin duplication, moving the
carriage from right to left, using the arm (B),
making sure that the pressure applied to the
tracer point is what the spring incorporated on
the carriage shaft requires.
Once duplication is complete, return the carria-
ge to its starting position. Next, remove the
keys by loosening the clamps.
If the key duplication has produced any burrs
on the duplicate key, these are removed using
the brush which has been specially fitted for
this purpose.

3.2.2 Duplication of narrow bit key. Use of rods 1.2
and 1.7
The rods are inserted between the bottom of the clamp and
the back of the key when the key to be duplicated has a
narrow bit. The rods prevent contact with the clamp itself by
making the key protrude further.
See figure 10
3.2.3 Duplication of keys without shoulders
Insert the two wedges (2) (see figure no.6) in the vertical gro-
oves (R) on each clamp, according to the length of the key to
be duplicated.
Rest the tips of the keys against the wedges (2). The keys are
now adjusted. Then tighten the clamps and before beginning
duplication it is advisable to remove the wedges.
See figure 11
3.2.4 Duplication of cruciform keys. Side 1 of the
clamp
This type of key should be inserted into the clamps from left to
right. Position the wedges (5) (see figure no.7) with the opening or
recess facing upwards, in one or other of the grooves (R) according
to the length of the key to be duplicated.
The teeth of the key are cut in three operations, by turning and
securing shoulder of the key against the wedge each time (5).
