Place the laser 2"–3" (5–8 cm) from the second wall. To test
the front laser dot, make sure the front of the laser is facing
the wall (Figure

until the laser dot hits point P2.
6.
Turn the laser 180˚ and aim the laser dot near point P1 on
the fi rst wall, and mark point P3 (Figure
7.
Measure the vertical distance between points P1 and P3 on
the fi rst wall.
8.
If your measurement is greater than the Allowable
Distance Between P1 & P3 for the corresponding
Distance Between Walls in the following table, the laser
must be serviced at an authorized service center.

Repeat steps 2 through 8 to check the accuracy of the right
dot and then the left dot, making sure that the laser dot you
are testing is the laser dot facing each wall.
Level Dot Accuracy - Square
Checking the level calibration of the laser unit requires a room
at least 35' (10m) long. All marks can be made on the fl oor
by placing a target in front of the level or square beam and
transferring the location to the fl oor.
NOTE: To ensure accuracy, the distance (D1) from P1 to P2, P2
to P3, P2 to P4, and P2 to P5 should be equal.
1.
Mark point P1 on the fl oor at one end of the room, as
shown in Figure
2.
Turn the laser ON and press
ahead, and below the laser.
3.
Place the laser so that the down dot is centered over point
P1 and make sure the front dot points toward the far end of
the room (Figure
4.
Using a target to transfer the front level dot location on the
wall to the fl oor, mark point P2 on the floor and then point P3
on the floor (Figure

Move the laser to point P2 and align the front level dot to
point P3 again (Figure
