Yes, yes, yes: I know that Google Is My Friend, but my real friend is the DIY Wiki, which [hopefully] distils the best of advice. And this one doesn't appear there yet, as far as I can see...
I have two Bosch hedge trimmers, a couple of years old now, and they are getting worn, gunged, and less sharp. (One is mains, one is rechargeable BTW.)
I'd like to separate the blades, rub them down a bit, and remove the gunge that has [probably] accrued over the years in the blade assemblies. However, I'm very leery of doing this unless I can be sure to put them back together exactly right. Otherwise, they'll end up worse than they started out.
Is there a recommended procedure for sharpening and renovating a hedge trimmer?
Cheers John
