The blades on my Braun complete 8975 are not sharp anymore.

its letting you know that the battery's are not charge or are not chargeable so change the battery's first then you will find out what's next.

You will find replacement parts at shaveroutlet.com. See link below

http://shaveroutlet.com/braun-8000-series-360-complete-foil-and-cutter-p-143.html

push in the shaver on/off switch and push the trimmer all the way up until it is fully extended. the trimmer should work in this position

Have you tried taking out the cutter block and reinstalling it? Otherwise, I think it should turn off automatically within about 7 days...

you can buy replacement cutter blocks and foils at walmart...about 50 bucks.

You replace foil cutter, that braun complete 8975 replacement foil and cutter blades is braun series 3 combi 30B foil and cutter replacement pack.

Hi,

I had same problem, at first I could not find out how to seperate the small silver cover with the on/off switch from the rest. After removing the 3 torx screws, 1 at the power entrance, and 2 under the shaver blade. You can remove the black cover. I also removed 2 more torx screws to separate the battery, from the rest, (don't know if thats really necessary). The silver covers are 'clicked' into eachother. When lifted the part where the battery part was screwed into, the silver parts became partly seperated, then you can pull the part apart.
I cleaned/washed the trimmer part with wd40 contact spray.
Assembled the parts, and made sure that the little plastic nodge was came into the trimmer.
Cleaned it all (removed leaking wd 40) and works fine again.
Hopefully this is helpfull to anyone.

Goodluck,
Adrian
