5. OPERATION AND FUNCTIONS

5.1 DEPTH ADJUSTMENT

See Figure 5
Switch off the power switch (11), switch off the
master switch (15), close the protective screen (16)
and check that the machine is NOT connected to
the battery charger.
- Secure the two adjustment keys (R) in "side 1" of the clamps
so that the upper edge of the adjustment key is in contact
with the inner face of the clamp (J).
- Raise the carriage to move the clamps closer to the cutter
(C) and the tracer probe (T).
- Position the tip of the tracer probe (T) against the flat edge
of the adjustment key. While in this position, manually rotate
the cutter one full rotation in the opposite direction to stan-
dard operation.
- The depth has been set correctly when the cutter brus-
hes slightly against the adjustment key.
- If the cutter rotates freely, it is too far back from the
tracer and the cutting gear is set too shallow. The depth
requires adjustment.
- If the cutter gets stuck on the adjustment key, it is too
far forward from the tracer and the cutting gear is set too
deep. The depth requires adjustment.
- To adjust the cutter depth, move the micrometric tracer as
follows:
- Loosen the stud bolt (S) to release the tracer but leaving
the stud bolt (S) very gently touching the hidden part of
the tracer. This will avoid any involuntary rotation of the
tracer when moving it forwards or backwards.
- Rotate the control wheel (W) clockwise to move the
tracer backwards.
- Rotate the control wheel (W) anti-clockwise to move the
tracer forwards.
Once the depth has been adjusted, re-secure the tracer
probe using the stud bolt (S).
See Figure 7

5.2 LATERAL ADJUSTMENT

See Figure 6
- Lateral adjustment is fixed and calibrated during factory
assembly. It will therefore not need to be adjusted. You can
check that this calibration has been performed correctly as
follows:
KEY CUTTING MACHINE
Switch off the power switch (11), switch off the
master switch (15), close the protective screen (16)
and check that the machine is NOT connected to
the battery charger.
- Secure the two adjustment keys (R) in "Side 1" of the
clamps so that the upper edge of the adjustment key is in
contact with the inner face of the clamp (J).
- Ensure that the positioner support faces (H) coincide
perfectly with the upper edges of the adjustment keys (R).
If this is not the case, loosen the stopper screw (H) on the
right-hand side and re-secure it in its correct position.
- Raise the carriage to move the clamps closer to the cutter
(C) and the tracer probe (T).
- Insert the tip of the tracer probe (T) into the notch on the
adjustment key (R). While in this position, manually rota-
te the cutter one full rotation in the opposite direction to
standard operation. Ensure that the cutter brushes slightly
against the notch of the adjustment key.
See Figure 8

5.3 KEY COPYING

- Rotate the clamps towards the side you will use for holding
the keys.
- Insert the original key into the left-hand clamp so that the
notched section more or less coincides with the edge of the
clamp. With the key in this position, secure it in place by
rotating the knob (A).
- When using SIDE 1 or 2: support the shaft of the
key correctly on the base of the clamp.
- When using SIDE 3 or 4: correctly insert the key
guide into the clamp guide.
- Insert the blank key into the right-hand clamp and align
the two keys as follows:
- Raise the stoppers using their corresponding knob
and support them against the upper shoulders of the
keys.
- With the blank key in this position, secure it in place
using the knob (A). NOTE: Both the original key and
the blank key should be inserted from the left-hand
side of their clamps.
- Remove the stoppers from the keys so they do not
interfere with the key cutting process.
Raise the protective screen (16) and press the safety switch
(15).
- Switch on the machine so the cutter begins to rotate.
- Bring the keys towards the cutter (C) and the tracer probe
(T). Remember that you should work from left to right.
- Press the original key against the tracer probe and begin
the duplication process, moving the carriage assembly
sideways by operating the carriage movement control (G).
- After completing the duplication process:
- Return the carriage assembly to its rest position.
