Excellent tool. Time saver. Easy to use.
I own 7 chainsaws from 12 inch.limbing saw to 5 foot monster saw. Previously used a file and joint bar attached file tool. Always ended up with uneven cutters that would curve in long cuts. Just received my 610-120 , set up per instructions which were clear and concise and sharpened one of my curve cutting chains. Chain cuts like new now. One tip when countouring the depth gauge wheel is to lay the dressing stone perpindicular to the wheel and drag it back and forth turning the dressing stone frequently. As long as pink dust is coming off the wheel it's working. Hold the stone in place and you will be there all day trying to countour the wheel. Took me about 30 minutes using this method. Wear gloves and safety glasses when contouring any of the wheels that come with the tool. Love the hydraulic clamping and the nice wide cutter backstop. I found that once set up properly, I only need to take off a couple whisker widths of cutter to have a chain that cuts like new.
