4. PREVENTIVE MAINTENANCE INSTRUCTIONS
WARNING
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.
Do not allow liquid, spray or vapour the equipment, as they may cause short circuits or
corrosion. Use white grease Molikote Longterm W2 for any lubrication required.
In case of replacement/maintenance of Tubehead, Folding Arm and Extension Arm it is
necessary 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.
