Replacing The Fuses; Replacing The Motor - JMA NEO Notice D'utilisation

secure two flat key blanks in the clamp and perform the vertical adjustment of the
tracer.
the tracer must be locked (deactivate the movement spring).
remove the two flat key blanks.
secure the key in the clamp using the P-win template.
the original key should be secured with the perforated side facing up.
enter the tracer exactly in one of the points and lock the machine head at that height.
Perform cutting.
See figure 10
3.2.8 jis-4.P keY
use the drill/tracer: F-11 / P-11.
secure the key in the clamp using the ad-Mj adaptor.
secure the adaptors in the clamp.
secure the key in the adaptor up against the turning plate of the adaptor.
Vertically adjust the tracer.
the tracer must be locked (deactivate the movement spring).
Perform first cut.
turn the two keys to the other side of the adaptor and proceed according to the previous
process regarding the placement of the keys.
Finish second cut.
See figure 11
3.2.9 Fo-6.P keY
use the drill/tracer: F-22 / P-22.
secure the key in the clamp using the corresponding ad-Fo adaptor.
Position and secure the adaptors in the clamp with the exterior of the clamp.
when positioning the key, ensure it is flat so the cuts can be symmetrically distributed
on the key.
the tracer must be locked (deactivate the movement spring).
enter the tracer in the groove of a letter. lock the height of the machine head and raise
the tracer slightly so it does not drag the adaptor.
Perform cutting.
See figure 12
reading the cut oF the original keY
the original key has six duplicate positions, which are defined by the letters a, b, c, d,
e and F, as shown in the following figure.
in each of the positions of a key, there are four different possible combinations (defined
by numbers), which are displayed below and numbered:
!
1 2
"height" no. 1 indicates that it should not be duplicated. Position no. 2 indicates that
there is a small groove in the key. when it is larger, it corresponds to height no. 3.
height no. 4 is for the greatest grooves in a key.
therefore, the key is taken and marked with combinations from one of six positions, as
indicated below:
Position a b
coMbination 3 4
note: the combination number series acts as the key code.
4. MAINTENANCE
when carrying out any maintenance operation, the following requirements must be
fulfilled:
3 4
c d e F
1 2 4 2
1. never perform an operation with the machine running.
2. the power supply cable must be disconnected.
3. the manual instructions must be strictly followed.
4. use original spare parts.
4.1 ADJUSTMENT OF THE CLAMP
the machine leaves the factory with the clamp (M) regulated, meaning subsequent
adjustment operations are required. if the clamp is replaced by a new one in the future,
the adjustment of the new clamp will need to be undertaken. to do this, follow these
steps:
1) take two tools (for example, the, P-1 and F-1) and secure them in their corresponding
tool belts, more specifically, with the points facing inwards.
2) slacken the three screws (20) that secure the clamp-holder slide to the structure of
the machine.
3) lower the machine head until the two tools are entered in the corresponding clamp
holes. in this position, lock the machine head using the "Machine head locking lever"
(6).
4) Finally, tighten the three screws (20) that secure the clamp-holder slide to the
structure of the machine.
See figure 13
4.2

REPLACING THE FUSES

if the machine does not start when the corresponding switches are activated, the fuses
must be checked. this operation can be carried out as follows:
1) switch off the machine using the general switch and disconnect the power supply
cable.
2) remove the fuse holders located next to the general switch.
3) check (use a tester) if a fuse has blown and, if so, replace it for another of the same
type and value.
4.3 TIGHTENING AND REPLACING THE BELT
to review the tautness of the belt (c) or to replace it, follow these steps:
1) turn off the machine using the general switch and disconnect the power supply
cable.
2) loosen the "tracer adjustment locking screw" (9) and unscrew the "tracer height
adjustment wheel" (8) until it is removed.
3) unscrew the four screws (21) that secure the "Machine head guard" and remove it.
the screws are located on the front and back of the machine.
4) loosen, but do not remove, the two screws (22) that fasten the motor support plate
to the machine head.
tightening:
while the motor is pushing the rear part of the machine, tighten the two screws (22).
rePlaceMent:
to replace the belt, the same operations as those for tightening should be performed,
but with a new belt.
See figure 14
4.4

REPLACING THE MOTOR

this operation is done as follows:
1) turn the machine off using the general switch and disconnect the power supply
cable.
2) loosen the "tracer adjustment locking screw" (9) and unscrew the "tracer height
adjustment wheel" (8) until it is removed.
3) unscrew the four screws (21) that secure the "Machine head guard" and remove it.
the screws are located on the front and back of the machine.
4) disconnect the power supply cables that reach the motor.
5) loosen, but do not remove, the two screws (22) that fasten the motor support plate
to the machine head.
6) remove the belt (c).
note: to facilitate the understanding of step 1) to 6), see the figure in section 4.3
(tightening and replacing the belt).
7) unscrew the set screw (23) that secures the motor fan belt and remove the fan belt
(g).
8) unscrew the four screws (24) that secure the motor (r) to its support plate and
remove it.
9) to set up the new motor, perform the same operations in reverse order.
See figure 15
4.5 REPLACING THE CONNECTION PLATE
this operation is done as follows:
1) turn the machine off using the general switch and disconnect the power supply
