BLADE GUARD FOOT – Guards the blade and keeps your workpiece from rising. Helps protect fingers from blade contact.
LEADING EDGE – The front edge of the workpiece that is guided into the blade. SAW BLADE PATH – Area or line of sight of the workpiece moving in line toward the saw blade edge. SURFACE – Top of workpiece being cut. TRAILING EDGE – The end of the workpiece edge last cut by the saw blade. WORKPIECE – Material on which the cutting operation is being performed.
ASSEMBLY AND ADJUSTMENTS Estimated Assembly Time: 5-10 minutes ! STORING THE T-WRENCH (FIG. B) The left rear side of the body (1) has a U-Shaped clamp holder (2) designed to store the T-wrench (3).
