ASSEMBLY AND ADJUSTMENTS
ALIGNING THE LASER BEAM (FIG. P, Q)
WARNING
For your own safety, never connect the plug to power source
outlet until all the adjustment steps are complete and you have
read and understood the safety and operational instructions.
The laser beam must always be correctly aligned with the
blade to ensure straight, even cutting.
Your tool is equipped with the laser cutting guide using Class
II laser beam. The laser beam will enable to preview the saw
blade path on the stock to be cut before starting the miter
saw. This laser guide is powered by the transformed alternat-
ing current supply directly through the power lead. The saw
must be connected to the power source and the laser on/off
switch must be turned on for the laser line to show.
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 adjustments.
• Laser Warning Label: Max output <1mW DIODE
LASER: 630-670nm, Complies with 21CFR 1040.10
and 1040. 11.
• CAUTION-Use of controls or adjustments or performance
of procedures other than those specified herein may result
in hazardous radiation exposure.
• CAUTION-The use of optical instruments with this product
will increase eye hazard.
• Do not attempt to repair or disassemble the laser. If unqualified
persons attempt to repair this laser product, serious injury may
result. Any repair required on this laser product should be
performed by authorized service center personnel.
NOTE: All the adjustments for the operation of this machine
have been completed at the factory. Due to normal wear and
use, some occasional readjustments may be necessary.
A. Check Laser Beam Alignment.
1. Mark a 90° straight line across a board to serve as a
"pattern line" to test laser alignment. Lay the board on the
miter table.
2. Plug saw into outlet and turn on the laser beam and line it
up with the pattern line.
3. Lower saw blade to pattern line and if blade is not flush
with the pattern line, adjust as follows in procedure (B).
B. Adjusting the Angle of the Laser Guide (Fig. Q)
1. Turn the laser element (2) in the desired direction to adjust
the laser angle. NOTE: Do not adjust the laser more than
¼ turn in either direction as this may damage the laser.
There are two flat sides on the laser element where you
can position an adjustable wrench for your adjustment.
C. Aligning The Laser Beam
Fig. O
1. Loosen only ½ turn at a time the four set screws (1).
2. Adjust laser by turning the left side set screws clockwise
to shift the laser line to the right. To shift the laser line to
the left, turn the right side set screws ½ turn at a time.
3. Once alignment of the laser is achieved, tighten only ½
turn at a time the four set screws (1).
