ADJUSTMENTS
THE LASER GUIDE (FIG. X)
The saw is equipped with a laser guide (1) using a Class IIIa
laser beam. The laser beam will enable you to preview the
saw blade path on the workpiece to be cut before starting the
miter saw. This laser guide is powered by the transformed
alternating current supply directly through the power lead.
WARNING
AVOID DIRECT EYE CONTACT Laser
radiated when laser guide is turned on. Avoid direct
eye contact. Always un-plug the miter saw from power
source before making any adjustment.

LASER BEAM ADJUSTMENT (FIG. Y, Z, AA, BB)
NOTE:
• All the adjustments for the operation of the laser guide has
been completed at the factory. If re-adjustment is needed,
please follow the adjusting steps A to C shown below.
• Laser beam is calibrated and set up to project to the right
of the blade.
• If you have any problem or question on the laser guide,
please call the Servise Center.
A. Checking Laser Beam Alignment (Fig. Y)
1. Mark a 90° straight line across the top side and front side
of a board to serve as a "pattern line" to test laser
alignment. Lay the board on the miter table.
2. Turn the laser on and align the laser beam with the
pattern line.
3. Lower saw blade to pattern line. If blade is not flush with
the pattern line, adjust the laser as in procedures B and C.
B. Adjusting the translation position of the Laser Beam
2
(Fig. Y, Z)
1. Remove the laser cover (2) by loosening the two screws (3).
Fig. X
2. Loosen two securing screws (5) slightly, hold the laser
assembly (4) to move the laser element (1) toward left or
right for adjusting the translation position of laser beam.
3. Once alignment of the laser is achieved, tighten the
securing screws (5) and replace the laser cover (2) by
tightening the two screws (3).

C. Aligning the Laser Beam (Fig. Y, Z, AA, BB)
1. Remove the laser cover (2) by loosening the two screws (3).
2. Turn slightly the laser assembly (4) for adjusting the
horizontal angle of the laser beam. When the laser beam
slopes from left
to right, turn
the laser
assembly (4)
anticlockwise;
when the laser
beam slopes
from right to
left, turn the
laser assembly
(4) clockwise .
3. Once alignment
of the laser is
achieved,
replace the
laser cover (2)
by tightening
the two screws
(3).
