1. INTRODUCTION
The Corrective Maintenance provides information about adjustment and replacement procedures concerning
the Oralix AC system.
Always disconnect the equipment from the mains supply before starting any maintenance action:
the mains voltage may be present on parts of the system (such as electronic board, Tubehead,
Folding Arm cable) even in the stand-by condition.
In case of replacement/maintenance of Tubehead, Folding Arm and Extension Arm it is neces-
sary to park the Folding Arm in a safe position by guiding the arm slowly to the horizontal position
opposing by hand to the springs action directed upwards (see figure in pag.B14).
If the Folding Arm is released without Tubehead and without opposing by hand to the springs
action, it is possible to damage the springs themselves.
