Question about Bosch Professional Fsn 1600

no, the circular saw must have a groove on the panel that fits on the rails. check the bosch website, there is a "guiderail compatible" symbol on the saw, e.g. https://www.bosch-professional.com/ch...

No, it does not fit on the GKS 18 V-Li because I own such a machine. greetings

Hello Knuusi, unfortunately no. A colleague of mine tried it once.
