Hey Glenn,
I don’t know if you have a batch that is faulty, but you probably know that according to the manual, the Makita hand trim router is only allowed for short, handheld use, that if it is “operated continuously at low speeds for a long time, the motor will get overloaded, resulting in tool malfunction” and that Makita has confirmed that as soon you install it into a CNC machine, your warranty is lost.
