Components and functional parts

2.4.1 Accesories
1 Size 18 spanner.
Keys to adjust the height and depth of the
2
teeth.
3
Wedges to adjust the tip of the key.
4
Recessed wedges to cut cross-shaped keys.
5 Set of allen keys (2, 2.5, 3).

2.4.2 Electric circuit

The main components of the electric circuit and
the electronic components are as follows:
1
Socket
Start switch
2
Motor

2.4.3 2-sided clamp
The clamp is designed to secure a different family
of keys on each side. The figure shows the possibi-
lities for cutting on each side of the clamp.
1) Cutting the key with support on the back:
• Keys with normal blade
• Keys with narrow blade
2) Cutting by means of clamping the key by the
guide (profile).

See Figure 3 3.1.1 Control and adjustment of the side distance
• Place the two adjustment keys (1) in the clamps, so
that the head of the adjustment key rests against
the inner stop of side 1 or 2 of the clamp.
• Then tighten the clamps.
• Move the clamps with the adjustment keys (1)
towards the tracer point (I) and the milling cut-
ter (F), so that the adjustment keys are in the
correct position in respect of the tracer point
and milling cutter. This is done by gently moving

the slide over the tracer point (I) and the milling
cutter (F).
• If the grooves of the adjustment key do not
coincide properly with the tracer point and the
milling cutter, proceed as follows:
• By gently loosening the shaft screws (T), you will
be able to move the milling cutter to the right
or left. You have to move the milling cutter to a
position in which it coincides with the groove of
See Figure 5 the corresponding adjustment key. To carry out
this operation, you have to remove the motor
guard first.
• The distance is now perfectly adjusted, with the
tracer point and milling cutter coinciding with
the respective recesses of the adjustment keys.
Now tighten the shaft screws (T).
Control and adjustment of the cutting depth
3.1.2
• Place the two adjustment keys (1) in the clamps, so
that the head of the adjustment key rests against
the inner stop of side 1 or 2 of the clamp.
• Move the clamps with the adjustment keys (1)
towards the tracer point (I) and the milling cutter
(F), so that the adjustment keys rest on the tracer
point and the milling cutter.
• Turn the milling cutter by hand. If it gently rubs the
adjustment keys, the machine is properly adjusted.
• If the milling cutter turns freely, without rubbing,
this indicates that it is to far back in respect of the
tracer point and is not cutting deeply enough. On
the other hand, if the milling cutter becomes jam-
med up against the adjustment key, this indicates
that it is too far forward in respect of the tracer
point and is cutting too deeply.
• If either of these 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 freely and rubs
gently against the adjustment key. Then tig-
hten the tracer point screw (L).The machine is
now in perfect working order.
