Lateral Adjustment; Key Copying; Copying A Key With No Shoulder; Copying A Cruciform Key - JMA NOMAD V 0.1 Manual De Instrucciones

- 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

3.2 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

3.3 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

3.3.1 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

3.3.2 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

4.- MAINteNANCe

the following recommendations should be considered when performing any maintenance:
• Never do anything while the machine is running.
• The power cable should be disconnected first.
• The instructions in this manual should be followed carefully.
• Use original spare parts.

4.1 BRUsH RePLACeMeNt

replace the brush when it can no longer remove burrs. do so as follows:
1) Switch off the machine and unplug the power cord.
2) release the 4 screws securing the cutter and brush protector and then remove it.
3) insert the securing rod into the hole in the brush assembly.
4) using the 5 mm allen key, release the screw holding the brush in place.
5) replace the brush and secure it in place.
6) remove the securing rod and reattach the cutter and brush protector.
see figure 12

4.2 CUtteR RePLACeMeNt

the cutter should be replaced when it becomes worn. do so as follows:
1) Switch off the machine and unplug the power cord.
2) release the 4 screws securing the cutter and brush protector and then remove it.
3) insert the securing rod into the hole in the cutter assembly.
4) using the 5 mm allen key, release the screw holding the cutter in place. Bear in mind
that this is a reverse-thread screw.
5) carefully clean the new cutter and all areas that will come into contact with it.
6) replace the cutter and re-secure it using the reverse-thread screw.
7) ensure that the cutter is securely in place and facing the correct way (it rotates clockwi-
se).
8) remove the securing rod and reattach the cutter and brush protector.
9) after replacing the cutter, the depth adjustment process should be repeated. the steps
to do so are explained in Section 3.1.
see figure 13

4.3 PROBe RePLACeMeNt

the probe should be replaced when it becomes worn. do so as follows:
1) Switch off the machine and unplug the power cord.
2) release the screw (S) using the 3 mm allen key.
3) rotate the control wheel (W) until the probe (t) is fully removed.
4) insert and secure the new probe, ensuring that the flat side is facing upwards.
5) after replacing the probe, the depth adjustment process should be repeated. the steps
to do so are explained in Section 3.1.
see figure 14

4.4 CARRIAge DePtH ADJUstMeNt

a maximum cutting depth should be set in order not to damage the clamps or the cutter.
the distance between cutter/probe and clamp should be 0.1 mm. do the following if this
is not the case:
1) Switch off the machine and unplug the power cord.
2) raise the carriage and move the clamps towards the cutter/probe as far as the carriage
assembly will go.
3) loosen the securing bolt (d) with the 8 mm wrench.
4) adjust the screw (p) to achieve a separation of 0.1 mm.
5) Secure the screw (p) by tightening the bolt (d).
see figure 15

4.5 INteRIOR ACCess

for maintenance requiring access to the machine interior, do the following:
1) Switch off the machine and unplug the power cord.
2) Very carefully roll the machine onto its rear side.
3) remove the 4 feet. loosen the 4 screws (q) to do so.
4) remove the lower casing. remove the screw (o) to do so.
see figure 16

4.6 FUse RePLACeMeNt

if the machine fails to start when pressing the on/off switch, the condition of the fuses
should be checked. this is done as follows:
