2.6.3 MORTISE SLIDE three-sided clamp
The clamp is designed to secure a different fami-
ly of keys on each side. These are the different
sides:
Side 1: Side for cutting single or double blade
Side 2: For cutting pump keys.
Side 3: For cutting special YM25P keys. There is

How the machine works

3.1 MACHINE ADJUSTMENT

3.1.1 Control and side adjustment
• Fit the two adjustment parts (6) so that they fit flush
against the clamp, as shown in Figure 6.
• Move the clamps towards the tracer point (I) and
the milling cutter (F), so that the adjustment parts
fit on the tracer point and milling cutter.
• If the adjustment parts do not coincide with the milling
cutter and the tracer point, proceed as follows:
- Loosen the two screws (T) of the tracer point support
and, using a small plastic mallet, give a few gentle
knocks to the right and left so that it coincides with
the adjustment part. See Figure
- The distance is now perfectly adjusted, with the
tracer point and the milling cutter coinciding with
the respective adjustment parts. Now, tighten the
screws (T) of the tracer point support.
3.1.2 Control and adjustment of the cutting depth
• Put the two adjustment rods (7) in the clamps, as
shown in Figure 7.
• Move the clamps with the adjustment rods (7) towards
the tracer point (I) and the milling cutter (F), so that
the adjustment rods rest on the tracer point and the
milling cutter.
• Turn the milling cutter by hand. If it gently rubs
against the adjustment rod, the machining depth is
properly adjusted.
• If the milling cutter turns freely (without rubbing),
this indicates that it is not cutting deeply enough. On
the other hand, if the milling cutter becomes jammed
up against the adjustment rod, this indicates that it is
cutting too deeply.
• If either of these two situations should occur, proceed
as follows:
- Undo the screw (L) securing the tracer point (I) and
turn the micrometric screw (H).
- Move the tracer point forwards or backwards, until
the milling cutter turns and rubs gently against the
adjustment rod. Then tighten the tracer point screw
(L). The machine is now in perfect working order.
3.2.1 Cutting mortise lock keys
• Put the keys into the clamps, taking care that the blade of the
key rests on the inner stop of the clamp, as shown in Figure 8.
• If you have to cut a key with a very long blade, you may have
to insert the key until the tip comes up against the milling
cutter and tracer point, instead of the clamp, so that with the
stroke of the machine, it is possible to cut this sort of key.
• Start the machine and, holding the slide by means of the
handle (M), move the keys towards the tracer point (I) and the
milling cutter (F).
• We recommend that you work slowly, without forcing the
milling cutter. The rounded area is achieved by rotating the
clamp-holder slide with the handle. (N). It is best to do the
machining by moving the handle (N), from top to bottom.
• If the key cutting operation has left some burrs on the cut key,
these can be eliminated with the plane that the machine has
been fitted with for that purpose.
