Check the stock being cut for nails, knots, and other objects that may damage or buckle saw. Start the cut by placing your hand beside the cut mark with your thumb upright and pressing against blade. Start cut carefully and slowly to prevent blade from jumping. Pull upward until blade bites. Start with partial cut, then set saw at proper angle. Apply pressure on downstroke only.
