Vertical Alignment (Fig. M, N)
• Loosen the hex screws (3) using a 3 mm hex wrench,
manually rotate the laser adjusting knob (5) and move
the board from side to side as required until the laser
beam (10) lines up with the marked line (7). Keep
adjusting until the laser beam (10) and the marked line (7)
are aligned. Then carefully tighten the hex screws (3).
• Adjust the other laser beam (11) in the same manner.
Two parallel laser beams (10, 11) should look like
the right side drawing in Fig. N.
NOTE: The distance between the laser beams will vary
with board thickness; however, the laser beams must be
parallel.
Crosshairs Alignment (Fig. M, O)
• Place a board (12) flat on the table. Do not allow the board
to move from this position; use clamps if needed. Bring
the bit down until it leaves a slight perforation in the
board; then raise it back up.
• Using a 10 mm wrench, slightly loosen the nut (4) so
the laser beam crosses the perforation (13).
Tighten the nut (4).
• Adjust the other laser assembly in the same manner until
the laser beams form crosshairs (14) exactly over
the perforation (13) on the board (12).
• Re-check the vertical alignment
to ensure that the laser
beams did not shift during
the tightening process.
The drilling hole
is now at the center
of crosshairs for
accurate drilling.
• Replace the covers (1)
with the screws (2)
over the laser
assembly on
each side.
