TO CHECK FOR VERTICAL ALIGNMENT
1. The vertical alignment is set correctly when the line does not move horizontally (sideways) as the cutting head is
raised and lowered. If the vertical alignment is correct, disregard this section and move to "TO SET LEFT AND
RIGHT KERF ADJUSTMENT".
2. If the vertical alignment is not correct, turn the left and right kerf adjustment screws one half turn, clockwise.
Remove the screws on both sides of the laser unit cover (Fig. A). Remove the cover.
3. Use the 1/8" hex wrench to turn the left or right vertical alignment set
screws (Fig. E). If you move the cutterhead from the raised to the lowered
position and the laser line moves horizontally away from the blade, turn
the vertical alignment set screw clockwise to correct. If the laser line
moves horizontally toward the blade, turn the vertical alignment set screw
counter-clockwise to correct. (Fig. F)
4. Reinstall the cover removed in STEP 2.
Never turn the brass hex nut in Fig. E.
TO SET LEFT AND RIGHT KERF ADJUSTMENT
1. Use the 1/8" hex wrench (A) Fig. H to turn the left or right kerf adjustment screw that sets the laser line to either
side of the test cut (Fig. G). To adjust the left line, turn the left kerf adjustment screw counter-clockwise to move
the line toward the blade and clockwise to move the line away from the blade. To adjust the right line, turn the
right kerf adjustment screw counter-clockwise to move the line toward the blade and clockwise to move the line
away from the blade.
2. Remove the padlock. The laser miter saw is ready for normal use.

LASER MAINTENANCE

For best laser performance, perform the following
maintenance regularly:
1. Carefully clean sawdust from each laser lens (A)
Fig. I with a cotton swab (B). Do not use solvents of
any kind since they may damage the lens. Avoid
touching sharp points of the saw blade with your
hands or fingers. Dust build-up can block the laser
and prevent it from accurately indicating the
line-of-cut.
2. Remove the blade from the saw and clean pitch
build-up from the blade (Fig. J) Pitch build-up can
block the laser and prevent it from accurately
indicating the line-of-cut.
