The arm was basically sheet metal and the force of the blade coming forward too fast flexed the arm upward enough for the blade to just climb out of the cut. The motor stalled and the circuit breaker blew.edma194 wrote: ↑Sat Jul 03, 2021 2:45 pm
I don't understand the part about "climb" up out of the cut. How does the saw move upwards? If this were a sliding miter saw I could understand that happening because the blade is mounted on a lever arm, but on a RAS it slides on the rail at a fixed height over the table.
I purchased the saw new from Sears and it came with a one year in-home service policy. This is when Sears had there own service vans and would come right to your house. They initially setup the saw for me and it crosscut great. I began having problems when I started to rip with it--which was the reason I bought it. It ripped fine, but after changing back and forth from ripping to crosscutting a few times the saw would loose it settings and start to crosscut out of square and grab and run at me. I called Sears and they came out and set it back up for me. The service man asked me if I got the saw bound in a cut and I said no, it had been crosscutting and ripping fine up to then. When he heard I was ripping with the saw he said that was the problem. he said the saws had a problem holding their setup switching back and forth. He spent some time with me going over how to setup the saw so I could do it after the service contract ran out. I was quite disappointed, and sold the saw after just 2 years.
I bought the used 12" DeWalt 7790 from a cabinet shop going out of business because I had heard it was more heavy built and would hold its settings. And it has been perfect. I have never had any problems. I ripped all my sheet stock on it for about 18 years. I started using a Jet table saw in 2008 for ripping because I found it to be a little faster. Now that I'm retired, I am going to sell the Jet ProShop and go back to the DeWalt for ripping because the table saw takes up too much room. It has to sit in the middle of the room to use, whereas the RAS is up against the wall, ripping or crosscutting.
a good track saw would do the same thing .
