A. Checking Laser Line Alignment (Fig. 25)
1. Set the saw to a 0° miter and 0° bevel setting.
2. Use a combination square to mark a 90° angled running
across the top and down the front of a board. This line will
serve as the pattern line to adjust the laser. Place the
board on the saw table.
3. Carefully lower the saw head down to align the saw blade
with the pattern line. Position the saw blade to the left,
center or right side of the "pattern line" depending on
your preference for the laser line location. Lock board in
place with hold-down clamp.
4. With the saw plugged in, turn on the laser guide. Your saw
has been preset with the laser line to the left side of the
blade.
WARNING
When making laser line adjustments,
keep fingers away from the ON/OFF trigger switch
to prevent accidental starting and possible serious
injury.
