Key copying operation

Insert the original key in the left-hand clamp, keeping a
distance of from 2 to 3 mm between it and the edge of the
clamp. See figure 4
Tighten the clamp, keeping the back of the key correctly
supported on the base of the clamp.
Insert the uncut key in the right-hand clamp and before
taking the clamp, lift the gauge (C) and align the two keys,
making sure that the two calibre indices rest firmly on the
upper stops of both keys. Lastly, tighten the clamps.
Both the original key and the uncut key for copying must
be inserted from the left of the respective clamps.
Start the machine and by holding the carriage by means
of the handle (M), move the keys towards the copying
index (I) and the milling tool (F), by pressing the button
(P). Gauge (C) withdraws automatically when the carriage
moves towards the copying index and the milling tool.
Remember that the machine works from left to right.
Rest the original key against the copying index and begin
to work, moving the carriage from right to left, using
the arm (B). Make sure that the pressure exerted on the
copying index is the one required by the spring built into
the carriage shaft.
When the key has been copied, returned the carriage to
the original position. Now, withdraw the keys by releasing
the clamps.
If, when copying, burrs are left on the copied key, these
may be eliminated with the brush provided for this purpo-
se. See figure 10
3.4.1 Copying keys with narrow blades. Side 2 of
the clamp.(padlocks/letterboxes)
For copying this kind of key, and so that the milling tool reaches
the maximum cutting depth, use side 2 of the clamp as this allo-
ws you to cut more deeply when copying.

3.4.2 Copying keys without stops

Insert the two shims (2) (see figure no. 6) in the vertical
grooves (R) of each clamp, in accordance with the length of
the key to be copied.
Rest the tips of the keys against the shims (2). The keys
are adjusted in this way. Now, tighten the clamps. Before
starting to copy the key, it is advisable to remove the shims.
See figure 11
3.4.3 Copying the cruciform key. Side 1 of the clamp
This type of key must be inserted in the clamps from left to right.
Place the shims (5) (see figure no. 7) with the opening or recess
downwards, in one or other groove (R), according to the length
of the key to be copied.
The serrations of the key are cut in three positions, by turning and
locking the stop of the key on the shim on each occasion (5).
See figure 12

The copying
keys "Block B":

3 sided clamp

The clamp is designed to secure a family of different keys
on each side. Let's take a look at the different sides:
Side 1:
Side for copying lever tumbler keys with one blade or
twin blade.
Side 2:
Copying frontal keys.
Side 3:
Copying the special key FO-4P. In the clamp there is a 45º
groove that allows this special key to be copied.
For more details, see the chapters on key copying.
4.2 Control and lateral adjustment "Block B"
Place the two adjustment pieces (6).
Move the clamps towards the copying index (I) and the milling
tool (F) so that the adjustment keys rest on the copying index
and the milling tool. The machine carriage is released by loose-
ning the handle (B).
Should the adjustment keys not coincide with the copying in-
dex and with the milling tool, proceed as follows:
Loosen the two screws (T) of the support and, with a small plas-
tic hammer, tap this slightly to the right or left so that it coinci-
des with the adjustment key. See figure No. 2.
Now, the distance is perfectly adjusted and the copying index
and the milling tool coincide with the respective adjustment
pieces. Now, tighten to lock the support screws (T).
See figure 13
Control and adjustment of the cutting
4.3
depth of "Block B"
Place the two adjustment bars (7) on the clamps, as indicated
in the design.
Move the clamps with the adjustment bars (7) towards the co-
pying index (I) and the milling tool (F) so that the adjustment
rods rest against the copying index and the milling tool. The
machine carriage is released by loosening the handle (B).
Turn the milling tool with your hand. If the milling tool rubs
against the adjustment rods slightly, the machine is correctly
adjusted.
If the milling tool turns freely, without rubbing, this indicates
that it does not cut at a sufficient depth. On the other hand, if
the milling tool jams in the adjustment rod, this shows that the
cut is too deep.
If one of these two incidents occurs, proceed as follows:
Release the set screw (L) that locks the copying index (I) and
turn the micrometric screw (H). See figure no. 3.
Bring the copying index forward or backward until the milling
tool turns and rubs against the adjustment rod very slightly.
Now, tighten the screw (L) of the copying index. The machine
is now in perfect working order.
