Operating Tips

• Use only new, high-quality, name brand AA batteries or specified
rechargeable DEWALT12V Li-Ion pack for best results.

• Ensure batteries are in good working condition. If the low battery
red indicator light is flashing, the batteries need replacement.

• To extend battery life, turn laser off when not working with or
marking the beam.

• To ensure the accuracy of your work, check to make sure your
laser is calibrated often. See Field Calibration Check.

• Before attempting to use the laser, make sure it is positioned
securely, on a smooth, flat surface.

• Always mark the center of the beam created by the laser.

• Extreme temperature changes may cause movement of internal
parts that can affect accuracy. Check your accuracy often while
working. See Field Calibration Check.

• If the laser has been dropped, check to make sure your laser is
still calibrated. See Field Calibration Check.

Low Battery Indication

The DW089LR, DW089LG, DW0811LR, DW0811LG lasers
are equipped with a battery gauge as shown in Figure 1B.
The battery gauge indicates remaining power with each LED
representing 25%. The bottom LED will illuminate and blink
indicating that the level is low (below 12.5%) and the batteries
need to be replaced. The laser may continue to operate for
a short time while the batteries continue to drain, but the
beam(s) will quickly dim. After fresh batteries are installed
and the laser is turned on again, the laser beam(s) will return
to full brightness and the battery indicator level will indicate
full capacity. (A flashing laser beam is not caused by low
batteries; see Out of Tilt Range Indicator.) If all 4 LED’s on the
battery meter LED’s continuously flash this does not indicate
a low battery; see “The Battery Meter LED’s Flash” under
Troubleshooting.

Operation

To Turn the Lasers On and Off

(See Figure 1)

With the laser off, place it on a flat surface. Slide the Pendulum
Lock switch B to the Unlocked/ON position. The DCE089G/R
model has three ON/OFF buttons on the keypad C one for a
horizontal laser line D, one for a side vertical laser line E and
one for a front vertical laser line F (DCE089G/R only). The

DCE0811G /R has two lines -a horizontal line and side vertical
line. Each laser line is powered on by pressing its
ON/OFF button on the keypad. The laser lines can be powered

one at a time or all at the same time. Pressing the ON/OFF keys
again turns the laser lines off. Slide the Pendulum Lock switch
to the OFF/Locked position when the laser is not in use. If the
pendulum lock switch is not placed in the lock position all
4 LED’s will continuously flash on the Battery Meter.

Using the Lasers

Out of LEVEL Range Indicator

The lasers are designed to self-level. 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: (i) between 4° and 10° the beams flash
with a constant blink cycle; (ii) 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.

Using the Pivot Bracket (See figure 2)

WARNING:
Position the laser and/or wall mount on a stable surface.
Serious personal injury or damage to the laser may result
if the laser falls.:

The laser has a magnetic pivot bracket G permanently attached
to the unit. This bracket allows the unit to be mounted to any
upright surface made of steel or iron. Common examples of
suitable surfaces include steel framing studs, steel door frames
and structural steel beams. The bracket also has a keyhole slot

H

allowing the unit to be hung from a nail or screw on any

kind of surface.

Using the Laser with the CEILING Mount
(See Figure 5 )

The laser ceiling mount L (if included) offers more mounting
options for the laser. The ceiling mount has a clamp K at one end
which can be fixed to a wall angle for acoustic ceiling installation.
At each end of the ceiling mount is a screw hole M, allowing the
ceiling mount to be attached to any surface with a nail or screw.

with this tool could be hazardous.

If you need any assistance in locating any accessory, please
contact your nearest DeWALT service center or go to
www.dewalt.com on the Internet.

Leveling the Lasers

As long as the laser is properly calibrated, the laser is self­leveling. 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.

Maintenance

• To maintain the accuracy of your work, check the laser often to
make sure it is properly calibrated. See Field Calibration Check.

• Calibration checks and other maintenance repairs may be
performed by DeWALT service centers.

• When not in use, store the laser in the kit box provided. Do not
store your laser at temperatures below -5˚F (-20˚C ) or above
140˚F (60˚C).

• Do not store your laser in the kit box if the laser is wet. The laser
should be dried first with a soft dry cloth prior to storage.

Cleaning

Exterior plastic parts may be cleaned with a damp cloth.
Although these parts are solvent resistant, NEVER use solvents.
Use a soft, dry cloth to remove moisture from the tool before
storage.

Accuracy Check and Calibration

Checking Accuracy –

Horizontal Beam, Scan Direction (See figure 7)

Checking the horizontal scan calibration of the laser requires
two walls 9m (30’) apart. It is important to conduct a calibration
check using a distance no shorter than the distance of the
applications for which the tool will be used.

1. Attach the laser to a wall using its pivot bracket, with the
laser facing straight ahead toward the opposing wall (0 degree
position).

2. Turn on the laser’s horizontal beam and front vertical beam and
mark the beam position on the opposing wall directly across from
the laser. Always mark the center of the beam’s thickness.

3. Pivot the laser 180 degrees and mark the beam position on the
opposing wall.

4. Measure the vertical distance between the lowest mark Aand
the highest mark B. If the measurement is greater than the
values shown below, the laser must be serviced at an authorized
service center.

Distance Between Walls Allowable Distance

Between Marks

30’ (9m) 1/8” (3.0mm)

40’ (12m) 5/32” (4.0mm)

50’ (15m) 7/32” (5.0mm)

Checking Accuracy –

Horizontal Beam, Pitch Direction (See figure 8)

Checking the horizontal pitch calibration of the laser requires a
single wall at least 30’ (9m) long. It is important to conduct a
calibration check using a distance no shorter than the distance
of the applications for which the tool will be used.

1. Attach the laser to one end of a wall using its pivot bracket.

2. Turn on the laser’s horizontal beam and pivot the laser toward
the opposite end of the wall and approximately parallel to the
adjacent wall.

3. Mark the center of the beam at two locations (c, d) at least
30’ (9m) apart.

4. Reposition the laser to the opposite end of the wall.

5. Turn on the laser’s horizontal beam and pivot the laser back
toward the first end of the wall and approximately parallel to
the adjacent wall.

6. Adjust the height of the laser so that the center of the beam is
aligned with the nearest mark d.

7. Mark the center of the beam e directly above or below the
farthest mark c.

8. Measure the distance between these two marks
(c, e). If the measurement is greater than the values shown
below, the laser must be serviced at an authorized service
center.

Distance Between Walls Allowable Distance

Between Marks

30’ (9m) 1/4” (6.0mm)

40’ (12m) 5/16” (8.0mm)

50’ (15m) 13/32” (10.0mm)

Checking Accuracy –

Vertical Beam (See Figure 9)

Checking the vertical (plumb) calibration of the laser can be
most accurately done when there is a substantial amount of
vertical height available, ideally 30’ (9m), with one person on
the floor positioning the laser and another person near a ceiling
to mark the position of the beam. It is important to conduct a
calibration check using a distance no shorter than the distance
of the applications for which the tool will be used.

1. Place the laser on the floor and turn on both vertical beams.

2. Mark two positions where the beams cross on the floor

(f, g) and also on the ceiling h. Always mark the center of
the beams’ thickness.

3. Rotate the laser 180 degrees, and reposition it close to the

second mark gso the beam crossing is exactly on the original
marks (f, g) on the floor.

4. Mark the position where the beams cross on the

ceiling j.

5. Measure the distance between the two ceiling marks
(h, j). If the measurement is greater than the values shown
below, the laser must be serviced at an authorized service
center.

Ceiling Height Allowable Distance

Between Marks

8’ (2.5m) 1/16” (1.5mm)

10’ (3m) 3/32” (2.0mm)

14’ (4m) 1/8” (2.5mm)

20’ (6m) 5/32’ (4m)

30’ (9m) 1/4’ (6m)

Checking 90º Accuracy Between Vertical Beams (DW089LR/G)
(See Figure 10)

Checking 90º accuracy requires an open floor area at least 33’ x
18’ (10m x 5m). Refer to Figure 9 for the position of the laser at
each step and for the location of the marks made at each step.
Always mark the center of the beams’ thickness.

1. Set up the laser in one corner of the floor and turn on the side

vertical beam.

2. Mark the center of the beam at three locations

(a, b, c)on the floor along the side laser line. Mark b
should be at the midpoint of the laser line.

3. Move the laser to mark b and turn on both vertical beams.

4. Position the beam crossing precisely at mark b, with the side

beam aligned with mark c.

5. Mark a location d along the front vertical beam at least 5m (18’)

away from the unit.

6. Rotate the laser cross over mark b so that the side vertical beam

now passes through mark b, d.

7. Mark the location e where the side vertical beam passes by

mark d.

8. Measure the distance between marks d and e. If the

measurement is greater than the values shown below, the laser
must be serviced at an authorized service center.

Troubleshooting

The Laser Does Not Turn On

• Make sure AA batteries (when used) are installed correctly
according to (+) and (–) on the inside of the battery door.

• Make sure the batteries or rechargeable pack are in proper
working condition. If in doubt, try installing new batteries.

• Make sure that the battery contacts are clean and free of rust
or corrosion. Be sure to keep the laser level dry and use only
new, high-quality, name brand batteries to reduce the chance of
battery leakage.

• If the laser unit is heated above 120˚F (50˚C), the unit will not turn
on. If the laser has been stored in extremely hot temperatures,
allow it to cool. The laser level will not be damaged by pressing
the on/off button before cooling to its proper operating
temperature.

The Laser Beams Flash

The lasers are designed to self-level up to an average of 4°
in all directions If the laser is tilted so much that the internal
mechanism cannot level itself, the laser beams will flash
indicating that the tilt range has been exceeded. THE FLASHING
BEAMS CREATED BY THE LASER ARE 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.

The Laser Beams Will Not Stop Moving

The laser is a precision instrument. Therefore, if it is not
positioned on a stable (and motionless) surface, the laser will

continue to try to find level. If the beam will not stop moving,
try placing the laser on a more stable surface. Also, try to make
sure that the surface is relatively flat, so that the laser is stable.

The Battery Meter Led’s Flash

When all 4 LED’s continuously flash on the Battery Meter this
indicates that the unit has not been fully powered off using the
Pendulum Lock switch B. The Pendulum Lock switch should
always be placed in the LOCKED/OFF position when the laser
is not in use.
