B&d GT220 hedge trimmer

SOURCE: Black and Decker 16 in Hedge Trimmer

I use a dremel with a sharpening stone, if u don't have one you can also use a power drill with a small sanding disk (1 inch) and course sand paper (30 or 40 grit). or you can use a bastard file. its too tight to use any kind of angle guide so just take your time and do it by eye. it shouldn't take much to get them sharp enough to do the job, over-sharpening is unnecessary and dangerous, and will make the blades dull faster. sharpen all the free blades, top and bottom, then start the trimmers to advance the blades to free up the sides you couldn't get. i use a light penetrating oil to clean the blades first, then lithium grease spray to lubricate.

spray liberally with wd40, let side and hour spray rag with wd40 and clean blades and look for any bent teeth in blade that maybe binding them as u clean use pliers and screwdriver to move if any found, it is likely that wither sap dried or rust formed and is creating too much friction for blades to move wd40 will help free up blades

You may have a piece of metal between the moving blade and the stationary one. Also the motor may have been at the top of the stroke when it stopped. You may be able to "force" the blade to move a little. This may free it enough to work.

You can definitely pick up a sheer pin for that model. I know ereplacementparts.com has them usually pretty discounted, or just check out a local store, but make sure they are in stock.
