TO CHECK FOR VERTICAL ALIGNMENT

Fig. F

Fig. G

1.The vertical alignment is set correctly when the lines do not move horizontally (sideways) as the saw head is raised and lowered. If vertical alignment is correct, go to “TO SET LEFT AND RIGHT KERF ADJUSTMENT”.

2.To adjust, turn the left and right kerf adjustment screws one half turn clockwise. Take off the laser unit cover by removing the phillips screw on either side of the cover. (Fig. A).

3.Use the 1/8" hex wrench to turn the left or right vertical alignment set screws. If, as the saw head goes from a raised to a lowered position, the laser line moves horizontally away from the blade, turn the vertical alignment set screw clockwise to correct. If the laser line moves horizontally towards the blade, turn the vertical alignment set screw counter-clockwise. (Fig. F)

4.Reinstall the cover removed in STEP 1, and continue to “TO SET LEFT AND RIGHT KERF ADJUSTMENT”.

TO SET LEFT and RIGHT KERF ADJUSTMENT

1.Use the 1/8" hex wrench to turn the left or right kerf adjustment screws and set the laser lines 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. (Fig. H)

Observe the laser CAUTION label (L)

Fig. H.

2. Remove the padlock and use the saw normally.

DUAL LASERLOC™ MAINTENANCE

For best laser performance, perform the following maintenance regularly:

DISCONNECT THE MACHINE FROM

THE POWER SOURCE.

1.Carefully clean sawdust from each laser lens (A) Fig. J 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. K) Pitch build-up can block the laser and prevent it from accurately indicating the line-of-cut.
