5.Slide the jig back to the base stop, place the workpiece on the base stop, and clamp the workpiece against spacer block and back stop as shown in Figure 20.

MAKE SURE the blade clearance is adjusted correctly! DO NOT adjust the work support plate any closer than 1⁄8" from the saw blade. If the blade contacts the work support plate, severe injury may occur. If the blade must be closer than 1⁄8" for special circumstances, fasten a block of wood through the holes in the work support plate to prevent the saw blade from contacting the jig.
6.Slide the jig up next to the saw blade, and use the major and micro adjustments (Figure 21) to line up the layout lines on the workpiece with the saw blade.
Note: The major adjustment sleeve allows for quick adjustment of the jig positioning, and the micro adjustment knob fine tunes the quick adjustment that was made.
