Many write that the cut is oblique due to the crooked bed or backlash. In fact, the problem is in the "crooked hands". With a lot of pressure on the device during cutting, the disk bends and the cut turns out to be oblique. I'll add a review: After 6 months of infrequent work with a saw, the front double-row rotor bearing fell apart and jammed. I didn’t load the saw heavily, I let it rest, cool down. Perhaps there was a defective bearing, which does not account for the largest load. By the way, at the opposite end of the rotor is a single-row and half as much. The gearbox is intact. I will add photos.
