I purchased the saw/cart combo a month ago for an upcoming kitchen remodel, started this job on Sat and used the saw extensively accomplishing all of my shop work on site. I had some problems keeping the blade 90 to the table during operation and was finally forced to rig the adjustment so that it would not move. In more detail, when I lock the blade angle I can still very easily move the adjustment knob and see the blade come off 90, also had the fence move twice during a cut. The other problem I had was ripping oak stock for the countertop edge. This saw had a pretty rough time going through this 2" stock even feeding very slowly the motor was working way too hard. On the bright side I do like the portability and it did excellent ripping full sheets of 3/4" I plan on exchanging this saw for another. Anyone have any ideas, btw I did the exact set up procedures twice so I don't think this was the problem. Also btw I think the on/off should be bigger easier to get to, maybe on the right side?
