This is an older discontinued model I have had for some time. it is 13 inch and I bought it new over 10 years ago. It has always done a fair job for me. I have used it for many years on rough sawn hardwood which I have cut and store to dry. I thought I would have to retire it when Sears folded and I no longer could get blades, but eventually I was able to find replacements that seem to work and hold up as well as the originals.Lately finding the screws that hold the blades down has become a challenge, (8 per blade, 1/4-28 x 3/4). Finally I ordered 10 of them online after having to drill out two of the originals.
This brings me to my current problem. When changing blades, facing the output side of the machine, with the cutter roller exposed, on the left side is a release that allows the cutter roller to revolve independent of the forward and rear feed rollers to facilitate blade changes. When you are finished changing blades you release this button from its depressed position to its normally raised position and the cutter roller is connected to the two feed rollers fore and aft and the machine is ready to operate.....normally.
in a very unsafe condition as I troubleshoot, I have established that while the button is depressed, the motor will run, the cutter roller will rotate correctly. When I shut it off, elevate the button to the full operating position, the motor shrieks as if, and probably is, locked. I have all covers off, everything is exposed, the belt is good and not slipping, the chains are looser than i would like, but serviceable and not available, the gears are in good shape. I have checked and eliminated everything and keep returning to that release for blade replacement, Which I have totally dismantled cleaned and rebuilt to no avail.
I am hoping within the brainpower on this Forum, someone has had a similar experience.
