I have cut through the power cord of my Bosch AHS 50 hedge trimmer. I have the electrical skills to replace the cord, but I cannot open the case. There is one deeply recessed screw with a non-standard head. Is there any way to open the case without going to a Bosch service agent?
Oops...! I don't know if this will help, I have a AHS 60 which I needed to open yesterday. I used a set of Alan (sp) Keys.with star shaped ends as opposed to square ends which did the job nicely. I'm assuming the screw heads will be the same on your model. Good luck.
