The Switch Blitz™ is equipped with the latest features. It comes with the unique Quick Nut on the cutter shaft that allows for changing cutters without using any tools. Simply hold onto the belt with one hand and turn the Quick Nut with the other hand to loosen and tighten the nut. Hand tightening the nut is sufficient to secure the cutter on the machine. The left-hand jaw is furnished with the Easy Flip Shoulder Gauge handle. This handle makes it easy to raise and lower the shoulder gauge. It also has the safety switch on the shoulder gauge, which prevents the machine from powering on if the shoulder gauge is not all the way in the down position.
