 Shutdown and restart dryer
In the following cases, the dryer must be fully shut down and depressurised:
◊  In the event of an emergency or malfunction
◊  For maintenance work
◊  For dismantling
Risk of injury from escaping compressed air!
Never remove any parts of the dryer, or manipulate the same in any way, as 
long as the unit is pressurised! Suddenly escaping compressed air might cause 
serious injuries. 
Prior to any work, release all pressure from the unit.

to stop the dryer in an emergency:
  Set main switch to position „0“.
  Close compressed air outlet valve.
The dryer is now shut down. Restart the dryer only after having eliminated all errors!
