Emergency button

Red mushroom-head button.

Pressing the button causes the machine to stop immediately in emergency mode, ceasing all movements.

Once pressed, the button can be released by pulling it outward.

Door safety device

The machine is equipped with a door safety device that:

• prevents the mixing cycle to be started when the door is open

• keeps the door locked during mixing of the can

During the mixing cycle, the door can only be opened if the mixing mechanics is in vertical position, i.e. when the can is clamped or

released. Opening the door in these cases causes all movements to be immediately stopped, for obvious safety reasons.

Door lock

As an optional device, a door lock system can be requested: it prevents door opening at any time of the cycle. With this option, it will

not be possible to open the door, neither during plate closing (clamping of the can) nor during plate opening (release of the can).
