Trimmer on 9000 seris broken needs replaced - Braun Syncro 7680 Electric Shaver

it like all other trimmers has a bump feeder on it. all you have to do is bump the head of the trimmer on the ground as it's running to let out more string. if the string has broken off and retracted into the head you will need to pull apart the head and let out some more string before you can continue however. it will only let the string out if its still sticking out from the hole it's supposed to be dispensed from.

Almost certainly, the trimmer is broken and will need replaced. The part and replacement video instructions can be fount at shaveroutlet.com

You may have wrapped it the wrong way. If not, your spring is either broken, the bend on the end which slides into the plastic has straightened, or the plastic spool has broken where it holds the other bent end of the spring.
