MAINTENANCE

Like all electrical equipment, this unit requires not only correct use, but
also maintenance and checks at regular intervals. This precaution will
guarantee that the equipment works safely and efficiently.

Periodic maintenance consists in checks carried out directly by the
operator and/or by the Technical Service.

The operator can carry out the following checks himself:

•

check the labels are intact and well attached

•

check there are no oil marks on the tubehead

•

check the remote control cable is not broken or scratched

•

check there are no external damages to the equipment which could
make it unsafe in terms of protection from radiation

•

check the scissors arm balance

WARNING:

If you find irregularities or damages the operator must inform the
Technical Service immediately.
