How do i remove a piston from a rht2660da to check if it has a broken ring

SOURCE: reassembling blades on hedge trimmer

the blades are stuck , i spray my trimmer with wd40 before every use to keep them juicy you should too. also sometimes if you hit a large stick it will put a divot in the blade cause ing it to stick. as for putting it together, find some one who can do it without directions. but when you use them next make sure you soak em good with wd40 or something if you dont i guarantee they will always stick. wd40 willl not hurt any shrubbery, as ive been doing it for years.

Just buy a file and push 3 or 4 down strokes down the same slope of the cutter toward the sharp edge. Never file on the flat top of the cutter, only on the slope. Support the frame using a saw horse or pick-up bed. The support makes the file cut the metal better. You can do the same thing with chain saws. You just need the file that fits the cutter. You just hold a consistant angle and count out the same number of strokes. Also, clean out junk between the moving parts, tighten any loose screws, and drop a few drops of 3 in 1 oil between the moving parts. Having things sharpened at a shop is inconvenient and expensive.

Hello. Get a can of starter fluid and a helper. Spray some into the air cleaner and start it up. Have your helper continue to spray a little starter fluid to keep it running for a minute or so. This will clear whatever blockage you have. Once it sounds like it is running well stop adding starter fluid and see. Joe
