10. MAINTENANCE
ATTENTION: no-one, except for the maintenance man, who must be a specialised technician, must be able to use the
automatic system during maintenance. Switch off the mains power supply to eliminate the risk of electrocution. If the power
supply must be left on for certain operations, each control device should be checked or disabled (remote controls, push
button strips, etc.) except for the one used by the maintenance man.

Each of the following operations must be carried out when it feels necessary and always every 6 months:
Door:
General checking of the door
Automation system:
Checking safety devices
12. EXTRAORDINARY MAINTENANCE
