self-checking the laser.
4. Use a 2mm allen wrench to turn the front adjusting screw to
position the laser beam forward and backward.
5. Use the side adjusting screw to position the laser beam left and
right.
6. Move the top beam to the intersection of the 4 dots shown in
Fig. A of self-check calibration.
7. Perform another self-check calibration as described previously to
make sure the laser is calibrated.
