I only have one problem with the saw. Tha first time I ran it, it just shut off after about 15 minutes of cutting. Had a hard time to restart it. I then cut for about an hour and it did it again, just like you shut off the switch on the saw. This time it was easier to start it again. I have now cut on and off for another 2 hours with no issues. Hopefully this was just a fluke. Saw cuts super good.
