• Accuracy adjustment should only be performed by a qualified
individual that understands basic adjustment principles.

Checking level accuracy

To check the level accuracy of your laser, place the unit on a flat, level
surface or tripod approximately 30 meters (100 ft.) from a wall.
• Align the X-axis so that it is square to the wall. Allow the laser to self-
level completely (approximately one minute after the laser begins to
rotate). Then mark the position of the beam (Position 1).
• Rotate the laser 180°, allow it to self level and mark the opposite side
of the first axis (Position 2).
• Align the Y-axis by rotating the laser 90° so that this axis is now square
to the wall. Allow the laser to self- level completely, and then mark the
position of the beam (Position 3).
• Rotate the laser 180°, allow it to self level and mark the opposite side
of the Y-axis (Position 4).
• The laser is within its accuracy specification if the four marks are
within ± 3 mm (± 1/8") from the center.

Checking vertical accuracy

To check the vertical accuracy of your laser, place the unit in the laydown
position on a flat, level surface approximately 15-30 meters (50-100 ft.)
from a wall.
• Hang a plumb line on the wall.
• Move the laser until the vertical, rotating beam is aligned to the plumb line.
• If the rotating beam is not plumb, adjustment is necessary.

Adjusting level accuracy

If the accuracy checks may lead to a necessity of re-adjusting the unit, a
corresponding description of how to adjust the level accuracy can be
found online at www.laseto.be.
