ADJUSTING THE DUAL LASERLOC™ LINES

Each of the laser lines have been aligned parallel to the blade at the factory and should not need any adjustment prior to use. However, left-to-right adjustment to the laser lines may be necessary if you change to a thicker or thinner kerf blade. For information on changing your blade, refer to the "MAINTENANCE: CHANGING THE BLADE" section of this manual. To adjust the laser lines to the edge of the cut, follow the instructions below.

HOW THE LASERS WORK

The laser units are mounted in a housing that is fitted into the upper blade guard of the miter saw (Fig. A). The laser units are aligned to the original equipment blade at the factory and are secured in place. A test cut has been made with each saw to verify laser setup. If your saw becomes misaligned or you desire additional precision, this guide is intended to assist you in fine tuning your laser miter saw.

HOW TO CHECK LASER ALIGNMENT

Make sure the saw is set to 0 degrees, miter and bevel, and clamp a 2"x 6" board on the saw. Create a partial test cut in the workpiece (Fig. C). Turn the laser “ON/OFF” switch (Fig. B) to the “ON” position. Leave the workpiece clamped in place for the remainder of the adjustment.

Observe the laser CAUTION label (L) Fig. B.

Place a padlock (A) Fig. B (with 3/16" shackle) through the hole in the trigger switch and lock to prevent accidental motor startup. This padlock MUST remain in place during the adjustment procedure.

The laser lines are properly positioned when the beams of light fall on the edge of the cut created by the blade (Fig. D).
