    Model SB1020 Blade Tension Proper blade tension is essential to avoid blade vibration, twist, or`slippage on the wheels. A correctly tensioned blade provides long life, straight cuts, and efficient cutting times. The three major signs of incorrect blade tension are: 1) The blade stalls in the cut and slips on the wheels, 2) the blade frequently breaks, and 3) the bandsaw does not make straight cuts.
