Hello everyone,

I have a Bosch GKS 68 BC circular saw, and the speed regulator (Part No. 1607233075) is faulty. Unfortunately, this part is no longer available for purchase, so I am trying to repair it.

I am looking for a wiring diagram or any technical documentation that shows how the motor and speed controller are connected in this saw. Specifically, I need to understand how the speed regulation system works and if there are any alternative solutions for replacing or repairing the faulty regulator.

Does anyone have access to a service manual, wiring diagram, or experience with repairing this type of speed control system? Any help or suggestions would be greatly appreciated!

Thanks in advance!
