6.2.2 – Replacing the handpiece
When replacing handpiece (13) by screwing it onto micromotor (14), take
care that the raised features on handpiece spindle (C) (see fig. 3) enter
their locations without having to force them; otherwise the motor coupling
(15, Fig. 5) may be damaged.
As soon as you detect excess resistance, unscrew handpiece (14) and
retighten it gradually; repeat this operation as many times as necessary
until you find the correct position.
6.2.3 – Replacing the motor
After approximately 2000 hours of duty it may prove necessary to change
the motor in order to restore the original performance characteristics of
the new unit.
Proceed as follows:
-
unscrew rear head (G) shown in Fig. 6 after releasing the cable to
prevent it becoming twisted;
-
unscrew the three screws (H) shown in Fig. 5;
