My unisaw blade raises (jumps) approximately 1/4" along with the
trunion when I hit the start switch. It does return to original
position once the motor has started. I have had the trunion out and
everything appears to be fine. Has anyone had this problem or have any
ideas. Thanks!!


New saw, old saw, Is this a new development or has it always done this.
Most cabinet saws do start with a jolt but the blade raising 1/4" is not
normal. Could the arbor bearings have way too much excess play?
