ALIGNING THE LASER GUIDE LINE
See Figure 20.
The laser guide will generate a red
when the blade is spinning. The red laser line will appear as
a broken line on the workpiece when the blade assembly is
in the uppermost position and the motor switch is activated.
This broken line will let you see your mark and the laser guide
line at the same time, and will assist you in lining up the mark
for more accurate cutting of the workpiece.
Align the laser line and the mark with the blade at the
uppermost position. Once both lines are in alignment, do not
move the workpiece until after you have finished cutting.
As the blade assembly is lowered toward the workpiece, the
broken line will become solid.
Make several practice cuts on different styles and thickness
of material.
ASSEMBLy
line on the work surface
Follow the directions below for using the laser guide.
To Remove your Mark:
Position the laser line near the left edge of your mark on the
work surface in order to remove the mark.
To Cut your Mark:
Position the laser line near or over your mark on the work
surface in order to cut the mark.
To Leave your Mark:
Position the laser line near the right edge of your mark on
the work surface in order to leave the mark.
After you have become familiar with using the laser guide,
you will be able to remove, cut, or leave your mark on the
work surface. Practice will teach you the correct position for
aligning the laser line with your mark.
