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.
Draw a line on the tile. 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 ac-
curate cutting of the tile.
Align the laser line and the mark with the wheel in the
cutting position using the laser adjustment dials.
Make several practice cuts on different styles and thickness
of material. Repeat the steps as necessary.
To adjust the laser:
 Plug in the saw and push the laser guide switch to show
the laser guide line.
 Position the laser line near the left edge of your mark on
the work surface.
 Turn the laser left/right adjustment dial move the laser
line either left or right.
 To move the laser line more towards the front or back
of the workpiece, turn the laser front/back adjustment
dial.
 When all adjustments are complete, secure adjustments
by turning the lock knob to the right.
