Using The Laser - DeWalt DCLE34220 Instructions Manual

NOTE: To ensure accuracy, the distance (D1) from
E
(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 floor 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 floor, mark point
(b) on the floor and then point (c) on the floor
(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 floor, mark the location
of two square beams as points (d) and (e) on the
floor (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 first square beam as
point (f) on the floor 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 floor as close as possible to point (a)
(Figure I #4).
• Measure the distance between points (a) and (g)
(Figure I #4).

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
find level as long as it is positioned on a flat 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 flash. There are
two flashing sequences associated with the out of
level condition.
• Between 4° and 10° the beams flash with a constant
blink cycle
• At angles greater than 10° the beams flash with a
three blink cycle.
When the beams flash 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.
