This jointer is two years old with moderate to light work. The motor now cannot maintain constant spin rate. Runs like a lawn mower with a carb problem. I cleaned it out and no help. Any suggestions?
It's tough to know for sure, but there are a couple of things to look for. At first I thought it might be bearing problems, but since the tool keeps varying its speed, I think it's motor problems. You can start by checking and replacing your carbon motor brushes. If they're worn or damaged it can cause that strange kind of behavior. If they're not the problem, then you might have armature problems.
Because the armature is so expensive, I would start with the brushes to see if that can fix the problem.
I rated this a 2 because the screws in the cutter drum are torqued so tight, the screw heads are stripped. now i have to drill and easy out the screws and replace them just so I can change the blades. I even tried to take the cutter head out, but that to is really in there tight. Now it will take at least another two weeks to get the screws. I'm about ready to throw it in the trash. I think its time to go back to craftsman!
I had this same issue. I tried applying heat and tapping the screws with a hammer and punch to get them to turn loose. I finally called and got them to let me talk to someone in the shop. They told me to use the hammer and punch at an angle. Once I did that the screws came out with no problem. It has been working without issue since then.
