3.8 

The blade of the thread trimmer is activated by a rotary magnet, to which an 
electric release control system (microswitch) is connected. This prevents the 
machine from starting when the blade is no longer in its inital position. Thus the 
release control system prevents a possible collision between blade and looper.
