Ah. That's an SDS jigsaw. I think I've got one somewhere - it's
a green one, isn't it?


But now it clicks when trying to undo it...

Mine started to undo itself when sawing. A PITA.


Anyone had one apart and know if this can be fixed?

Haven't had one of these apart, have had others to bits - they
aren't very difficult to deal with IME.


And if spares are still available

Ooh, nasty. They're a bit on the consumable end of the scale.
Spares should be available, but at a price... I've had spares
for things like this before, and fitted them (it's not economic
get them repaired by someone else), but it's a close call in
terms of outlay.


and if so from where (S London). I've got four different
Bosch power tools and this is the first one that's broken.

Hm. I haven't found vast reliability differences between these
and cheap makes. If you do take it to bits, do a write-up, &
I'll see if I can fix mine! Perhaps I'll try it anyway soon..
