4.4.3 WIRING DIAGRAM
The main components of the electrical circuit are the following:
1. General power supply
2. On/off switch
3. Bridge rectifier
4. Motor
5. Circuit breaker
See figure 4
2.4.4 SIDECLAMP
The clamp is designed to hold a different family of keys on each of its 4 sides:
SIDE 1: Keys supported on the SHAFT and NORMAL blade
SIDE 2: Keys supported on the SHAFT and NARROW blade
SIDE 3: Keys supported on the BOTTOM GUIDE
SIDE 4: Keys supported on the TOP GUIDE
See figure 5

5.- OPERATION AND FUNCTION
5.1 DEPTH ADJUSTMENT
• Disconnect the rear plug from the power supply to perform this operation in complete
safety and make it impossible for the cutter to start moving.
• 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 probe (T).
• Position the tip of the 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 standard
operation.
- If the cutter brushes against the adjustment key slightly, this indicates that the
depth has been set correctly.
- If the cutter rotates freely, this indicates that the cutter is set back from the probe
and the cutting gear is set too shallow. The depth requires adjustment.
- If the cutter remains stuck against the adjustment key, this indicates that the cutter
is set forward from the probe and the cutting gear is set too deep. The depth requires
adjustment.
• To adjust the cutter depth, move the micrometric probe as follows:
- Loosen the stud bolt (S) to release the probe but leaving the stud bolt (S) very gently
touching the hidden part of the probe. This will avoid any involuntary rotation of the
probe when moving it forwards or backwards.
- Rotate the control wheel (W) clockwise to move the probe backwards.
- Rotate the control wheel (W) anticlockwise to move the probe forwards.
• Once the depth has been adjusted, re-secure the probe using the stud bolt (S).
See figure 7
5.2 LATERAL ADJUSTMENT
• 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:
• Disconnect the rear plug from the power supply to perform this operation in complete
safety and make it impossible for the cutter to start moving.
• 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 positioner 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 probe (T).
• Insert the tip of the probe (T) into the notch on the adjustment key (R). While in this
position, manually rotate 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 lever (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 positioners using their handle and support them against the upper edges
of the keys.
- With the blank key in this position, secure it in place using the lever (A).
NOTE: Both the original key and the blank key should be inserted from the left-hand
side of their clamps.
- Remove the positioners from the keys so they do not interfere with the key cutting
process.
• Switch on the machine so the cutter begins to rotate.
• Bring the keys towards the cutter (C) and the probe (T). Remember that you should work
from left to right.
• Press the original key against the 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.
- Switch off the machine so the cutter stops rotating.
- Release the keys from the clamps.
- If the duplication process produced any burrs on the copy, these can be removed
using the brush that is provided with the machine for this purpose.
See figure 9
5.3.1 COPYING KEYS WITH A NARROW BLADE
To duplicate this type of key and in order for the cutter to reach maximum depth in the key
to be copied, "Side 2" of the clamp should be used.
5.3.2 COPYING A KEY WITH NO SHOULDER
• Insert the chocks (Y) into one of the vertical slots on one of the four sides of the clamps.
• Insert the original key into its clamp until the key tip rests against the chock (Y). With
the key in this position, secure it in place by rotating the lever (A). Repeat this process with
the blank key.
• Remove the chocks (Y), raise the carriage assembly and begin the duplication process.
See figure 10
5.3.3 COPYING A CRUCIFORM KEY
• Use SIDE 1 of the clamp for this type of key.
• Insert the star key chocks (X) into the vertical slots in the clamps so that the gap in the
chock is facing the cutter or probe.
• Insert the original key into its clamp until the key tip rests against the chock (X). With
the key in this position, secure it in place by rotating the lever (A). Repeat this process with
the blank key.
• Raise the carriage assembly and begin the duplication process.
• These keys have three notched blades. So the same steps will need to be repeated twice
more for the remaining two key blades.
See figure 11
6.- MAINTENANCE
The NOMAD duplicator machine requires no particular maintenance plan. Nonetheless,
certain parts should be checked regularly and eventually replaced once they become worn.
This particularly includes the cutter, the brush, the tracer and the belt.
Maintenance operations should be carried out by qualified professionals with the neces-
sary protective equipment for working safely. The instructions provided in this manual
should be followed carefully when performing any maintenance tasks and the following
instructions should be followed in general:
Before starting any maintenance operation, the machine must be turned off and
disconnected from the electrical network. The operator must ensure that no one
can access the machine.
Do not carry out any maintenance operation while the machine is running.
Original spare parts must always be used. The "CE" mark is guaranteed only if
original spare parts supplied by the manufacturer are used.
After the replacement of a component, make sure that the corresponding screws
are properly fastened.
DO NOT USE COMPRESSED AIR AT ALL! To keep the jaws and the carriage clean
of metal chips, it is recommended to use the brush supplied with the machine.
