4. Press Pulse to manually fire the laser and observe if the laser mark is centered on the tape as
below. If so, then the laser tube is aligned with 1st Mirror; if not, continue to step 5.
You should be able to see a small mark on the tape. If it is not noticeable,
press Pulse again.
Pressing Pulse activates the laser. Always make sure the path is clear
between the laser and its target. Never allow foreign objects between the
laser and its target. Take care not to leave any part of your body in the laser
path while pressing the Pulse button.
These marks are OK.
5. Cut the power to your laser.
6. Loosen the screws on its stand and place a shim under the bracket to raise the laser tube. Be careful
not to over-loosen the setscrews and not to overtighten them. Only adjust one stand at a time.
7. Repeat steps 1, 2, 4, 5, and 6 until the burnt hole is at the perfect center of the masking tape.
8. Retighten the setscrews.
These marks require adjustment.
