Startup and use of the micromotor
1. Before connecting it to the mains supply, make sure that the mains voltage coincides with
that of the micromotor.
Connect line cord (17), the micromotor (1), the Microhammer (2) and the pedal (4) to the
regulator (3).
ATTENTION. DO NOT ROTATE THE MICROMOTOR WITHOUT SHANK OR BUR.
2. Remove the originally shank and put the bur into the micromotor (1). You should open the
collet chuck, turning left the central part of the micromotor (1). Turn it close. Make sure that
the bur is well clamped. Put the point in the microhammer (2) then screw it slightly with the
pin bolt supplied. You can shape the point as you want previously. The point is made of
water tempered steel so you can harden it for a longer life.
3. Turn on the main switch (19). If everything is correct it will beep slightly. The regulator will
be idle ready to start up. You can see a red pilot lamp (8) illuminated on the frontal part.
Switch on the start up key (9), the display (13) will be illuminated. Just select the working unit
pressing the hammer sign (11). Then select the speed pressing the arrows (12) on the
frontal part. Hold the selected hand piece in one hand and tread on the pedal (4). The
selected speed remains stored, even with the machine off.
The start up/stop pedal (4) is essential to start up the machine.
4. In starting up the micromotor is programmed to turn right. If you want it to turn left you
should push the turn reversing key (10), then the green pilot lamp (7) will indicate that it is
turning left.
5. To avoid any malfunction in the machine, in case it is overloaded the red pilot (8) on the
front will blink. If it is blocked for more than four seconds the regulator (3) will be
disconnected. To continue working just raise your foot and tread on the pedal (4) again. If
overloading continues but not for so long to block the regulator (3), working process will
follow up to a safety threshold, when the regulator will be disconnected. Then you will see a
counter on the display (13). For 60 seconds the regulator (3) will regenerate and then it will
beep once it is ready to work again.
6. To change the collet chuck, untwist the protector lid, turn left the central part from the
micromotor (1) 90º and put a bur stem within it. Then slacken it with the spanner supplied
with the micromotor(1) for this purpose . Unscrew it anticlockwise.
Just proceed the other way round to assembly the machine. The collet chuck should be
turned till stop.
The concentric turn from the collet chuck to be verified comes to a peak value of 0.03mm.
In any case should you use the collet chuck opening system to stop the micromotor.
