Always shut off the saw and wait for the blade to stop before moving the GT Guide. Hold GT Guide in left hand with handle at 10 o'clock. Move it toward wood with left fin on saw top until right side fin touches wood. Pull backwards and to right while releasing. Move release sideways slightly to adjust side pressure.
Light pressure is usually best.
Normal hand pressure guiding wood is 5 pounds. That barely bends the side fin. Generally, you should be able to push wood through with one finger. When cutting plywood, very thin pieces, or multiple cuts, use the GT sticking sideways to a steel fence or the MVD accessory fenceplate. The steel fence plate can be attached to an auxilliary wood fence or directly to any aluminum fence.
