my mother got father a chain grinder for Christmas a few years back at my suggestion unfortunately she got it at at TSC, not my suggestion. I wanted to take it back and get a better one but by that time my brother had torn the box open and lost a couple things.. so we have a TSC grinder. enclosed are the pictures of the adjustments per the chart in the manual, I use .058, 3/8 chains. what I am not sure of, am I going deep enough into the tooth.? I went from the 1/8 wheel to the 3/16 wheel, as the chart said either was ok. sugges appreciated. Particularly how far to adjust the down stroke of the grinder.
