ACCURACY AND LINE TABLES COME FROM DW088CG
NOTE: To ensure accuracy, the distance (D1) from
(a) to (b), (b) to (c), (b) to (d), and (b) to (e) should
be equal.
1. Turn the laser ON and press once to display dots
above, ahead, and below the laser.
2. Mark point (a) on the oor at one end of the room,
as shown in Figure I #1.
3. Place the laser so that the down dot is centered
over point (a) and make sure the front dot points
toward the far end of the room (Figure I #1).
4. Using a target to transfer the front level dot
location on the wall to the oor, mark point
(b) on the oor and then point (c) on the oor
(Figure I #1).
5. Move the laser to point (b) and align the front level
dot to point c again (Figure I #2).
6. Using a target to transfer the front level dot
location on the wall to the oor, mark the location
of two square beams as points (d) and (e) on the
oor (Figure I #2).
7. Turn the laser 90° so the front level dot aligns to
point e (Figure I #3).
8. Mark the location of the rst square beam as
point (f) on the oor as close as possible to point
(a) (Figure I #3).
9. Measure the distance between points (a) and (f)
(Figure I #3).
• If your measurement is greater than the Allowable
Distance Between (a) and (f) for the corresponding
Distance (D1) in the following table, the laser must be
serviced at an authorized service center.
• Turn the laser 180° so the front level dot aligns to
point e (Figure I #4).
• Mark the location of the second square beam as
point (g) on the oor as close as possible to point (a)
(Figure I #4).
• Measure the distance between points (a) and (g)
(Figure I #4).
• If your measurement is greater than the Allowable
Distance Between (a) & (g) for the corresponding
Distance (D1) in the following table, the laser must be
serviced at an authorized service center.

Using the Laser
Leveling the Laser
As long as the laser is properly calibrated, the laser is
self-leveling. Each laser is calibrated at the factory to
nd level as long as it is positioned on a at surface
within average ± 4° of level. No manual adjustments
are required.
If the laser has been tilted so much that it cannot
self-level (> 4°), the laser beam will ash. There are
two ashing sequences associated with the out of
level condition.
• Between 4° and 10° the beams ash with a constant
blink cycle
• At angles greater than 10° the beams ash with a
three blink cycle.
When the beams ash THE LASER IS NOT LEVEL
(OR PLUMB) AND SHOULD NOT BE USED FOR
DETERMINING OR MARKING LEVEL OR PLUMB.
Try repositioning the laser on a more level surface.
