I just wanted to comment that a small flat-head screw driver can be used to remove the 4 screws (under the rubber handle piece) if you don’t have a Torx tool. The screws each have 1 small slot across the head and if you’re careful you can remove and re-install them without too much trouble.
Thanks again for helping to save me a lot of trouble with this Alex… and avoid having to buy a new electric razor!
