If it were a rose you would prune into the live part to get rid of all the dead bit to make sure it doesn't spread, but I don't know if that applies to acers. Wipe secateurs with meths in between to keep them clean.
Dordogne and Norfolk. Clay in Dordogne, sandy in Norfolk.
Acers do have a tendency to bleed quite a bit of sap after pruning unless they're completely dormant, which happens after about 4 weeks when the average temp is around 4C - which rarely happens in UK winters these days - at least in Essex. For that reason I tend to leave 1-2" of dead wood below the cut - so don't cut into live wood. Mine still grows very well, so any little dead bits are soon hidden.

Knowledge is knowing that a tomato is a fruit. Wisdom is not putting it in a fruit salad.
