INSTALLING BATTERIES FOR LASER
See Figure 13.
The laser battery compartment is located inside the battery
port for the 18 volt battery pack.
 Loosen the screw from battery compartment cover using
the Phillips end of the supplied blade wrench. Remove
cover and set aside.
 Install two AAA batteries according to polarity indicators
on the battery compartment cover.
 Replace the battery compartment cover. Reinstall screw
and tighten securely.
DANGER:
Laser radiation. Avoid direct eye contact with light source.
WARNING:
Use of controls or adjustments or performance of
procedures other than those specified herein may result
in hazardous radiation exposure.
USING THE LASER GUIDE LINE
See Figure 14.
Remove the battery pack. Using a square, draw a straight
line on the workpiece. When the laser guide switch is turned
on it will generate a red line on the work surface. This 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.
NOTE: The broken line may begin slightly skewed off of the
mark in the uppermost position. As the saw blade assembly
is lowered, at the approximate point the lower blade guard
starts to move, the laser line will be aligned with the mark and
remain aligned throughout the cut. This is normal. NEVER
attempt to move the workpiece while making a cut. Always
keep hands outside the "No Hands Zone".
With the saw arm at the uppermost position, move the
workpiece until the mark and the laser line are aligned. Once
both lines are in alignment, do not move the workpiece.
Clamp the workpiece.
Install the battery pack. Make several practice cuts on
different styles and thickness of material. Repeat the steps
above as necessary.
Removing Your Mark:
Position the workpiece so that the laser line is near the left
edge of your mark in order to remove the mark.
To Cut Your Mark:
Position the workpiece so that the laser line is near or over
your mark in order to cut the mark.
