All models are equipped with a precision fence, plus the F2 & F3 feature the Hi/Low aluminum extrusion known from European saws. The hybrid fence on the Laguna Fusion offers the best of European and American fence features. This fence is NOT designed to be used on the LEFT side of the blade! Rail or tube on the LEFT side is provided only to make the ON/OFF switch position. Permanently lubricated bearings & Acme screws are part of the internal DNA. Fusion 3 is the true successor to the original Fusion Table Saw. The task was simple: make a saw that was more refined, more precise, and cleaner.
