I don't know what it's for, or if it's even necessary (I found pix online, but they weren't any help as to function and purpose). and I'm inclined to change this to a Grizzly start/stop paddle switch regardless).īut I don't understand the reset button "addition" to the switch arrangement. I pretty much understand how a simple start-stop switch should be wired IF there wasn't that reset button (well, I found diagrams that I could follow. Unisaw switch-1 - small.jpg Unisaw switch-2 - small.jpg Here's pix of the switch and reset button and the wiring: The switch(es) were probably added at that time? 83-621) and is likely a mid-1980's replacement of the original motor. You want the shaft to have very little lateral movement - just enough to prevent binding/allow the handle to turn.I need help with understanding the "reset button" part of the switch on my Unisaw, and what it's for (and whether to just replace the whole thing).īackstory: I finally ran 230V to my garage this past weekend, and rewired my 1975 Unisaw (Model No. Turn the saw over on its top, and look at the mechanism from below, and watch for movement. Looseness here would prevent the locking mechanism above from working you should be able to push and pull the tilt handle without turning the knob, and see movement in the whole assembly. They could be loose, either allowing slippage near the trunnion or near the cabinet.

Second, there are set collars (part 70) on the tilt shaft inside the cabinet that should be tight on the shaft. If that's not working, check the next issue before attempting to fix. The lock knob should tighten against the handle, and the handle should be tight against the flange (part 7/TAB-108 on the parts diagram). There are two things I would check if the tilt was slipping.įirst, that the lock knob on the handle is working. I've rehabbed a number of saws that are built similarly (34-500 & 34-600 Homecraft). If figured this is the cause of the power loss because the blade is essentially binding itself during ripping.

I set it to 90 degrees and after 2 min of free running without cutting, the blade had drifted 9 degrees off 90. It wasn't horrible but after 2 days or so of use I decided to test it. Once I did this i started to notice the blade and was beginning to drift during use. I then bought a digital angle finder and it helped me to get the blade to a perfect 90 degrees. It helped a little but still lost power after a 10-15 seconds of ripping. I noticed during replacing the bearing that the Arbor was blueing so i figured I was on the right track. I thought it might be the bearings so I replaced them. It would rip well for about 10 seconds and then would begin to lose power. I found a old Rockwell 9 inch table saw free on the side of the road.
