POCKET CUTS (PLUNGE CUTTING)

A pocket cut is one which must be made inside the area of the material and not starting from the edge. Mark the area clearly with lines on all sides. Start near the corner of one side and place front edge of saw base firmly on the work. Hold saw up so blade clears the material. Be sure you have adjusted the blade properly for depth of cut. Push the telescoping guard lever all the way back so the blade is

exposed as shown in Fig.

17.Start the motor and lower the blade into the work. After the blade has cut through, and the base rests flat on the work, follow the line right up to the corner. Use a keyhole or bayonet saw to cut the corners out clean.
