Emergency opening of the working chamber door

CAUTION

Cutting injuries caused by rotating tools

If a power failure or a machine malfunction occurs during machining, the spindle including the inserted tool keeps rotating. If you touch the rotating tool, you will suffer from cutting injuries.

  • Wait until the spindle has stopped rotating before performing an emergency opening.
  • Do not carry out the emergency opening during regular operation.
NOTICE

Improper opening or closing of the working chamber door

To avoid damage, heed the following instructions when you manually open or close the working chamber door.

  • Disconnect the machine from the eletrical source.
  • Prevent the working chamber door from twisting by pushing or pulling it with both hands.
  • Only apply as much force as needed to overcome the resistance.

You perform an emergency opening as follows:

  1. Switch off the machine at the main power switch. Disconnect the machine from the eletrical source.
    • You can manually open the working chamber door.

    The working chamber door should move sluggishly, but evenly. If the movement is jerky or the working chamber door gets stuck, do not use excessive force.

  2. Open the working chamber door by pushing it straight and evenly upwards with both hands.
  3. If the door can only be moved by making a major effort, make sure that the guide rails at the back of it are clean.
  4.  

  5. If the working chamber is wet, leave the working chamber door open so that the working chamber can dry.
  6. Close the working chamber door by carefully pushing it downwards with both hands.
