Your guide saved me from purchasing a new device.

After replacing the batteries it works again like a charm!

Thanks this was helpful. The Braun Series 3 Hair Clipper HC3050 has a VERY similar design. Some additional notes: After removing the screws, it takes a bit of force to get the back separated from the front. I had to gently pry it apart with a screw driver. The very inside is slightly different, but same concept.
