My hedge trimmer blades do not move when I turn it on

SOURCE: Ryobi 18V Hedge Trimmer Blade Question

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.

Try loosening the bolts up on the blades just enough to allow the washers to move freely a little, spray the blades down (but don't soak them ) with WD40 to lubricate the blades, that should solve it. If that doesn't do it then you may need to pull the gear housing cover off to see if something is jammed.

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

My trick is to make sure that I always lube the blades after each session with a 3/4 engine oil + 1/4 kerosene mix - making sure that every tooth gets a drops or 2, then run it for a seconds to spread the oil & leave the blades overlapping. Doing this allows the blades to self sharpen I've found. 2 stroke oil , unmixed is about the perfect viscosity aswell.
