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”.
