Prodecoder Automatic Grimaldello Bulgaro has 2 main wheels and 2 additional small tension handles.
1. Turbo wheel – when you turn the turbo wheel you cause movement of the pins. This is the main operational wheel.
2. Tension wheel – by giving (and holding) the tension to the left and to the right, you are turning the turbo wheel. This is how you cause traction between the pins and the respective plates (levers) of the lock. This is the main methodology Prodecoder Automatic uses to work on the self impressioning method.
The wheel has two stop points. And they must remind you that you need to perform a progressive opening. You should NOT force the tools.
3. Small tension handles- you can easily screw them on the Tension wheel (2). Their purpose is for convenience – with them the operation is much easier. Additionally they have amazing grip with your hand and you are able to feel the tension of the levers.
