The product was damaged when received. I had to pound out the fan shroud on the motor as it was collapsed inward, although the box and styrofoam were intact. I had to thread with a M8-1.25 tap for two of the holes that the feet screw into (no threads). Hurray for YouTube for folks that have made up for the poor instructions. Now 4 table saw blades are sharpened and I will get better at it with more practice. Beats me driving 70 miles round trip to drop off circular saw blades, wait a week, 70 miles again to pick up, and $20 per blade for the trouble.
