CAUTION When tightening, the laser may move. Use caution to prevent any movement, as this can result in
drilling the table anchor holes in the wrong location.
12.) After the laser is centered, notice that the laser beam also appears on the back wall. Place a
piece of masking on the wall and carefully mark a line on the tape where the laser appears.
This line is later used in the table alignment. This line is also useful in determining if the laser
unit moves during the alignment process.
13.) Remove the alignment centering plate and store it in the alignment case.
