Batteries (fig. 1)
BATTERY TYPE
This laser operates on four LR6 (AA-size) batteries.
TO INSTALL BATTERIES
1. Lift up the battery compartment cover (a) as shown in figure 1.
2. Insert four fresh LR6 (AA-size) batteries in the compartment,
placing the batteries according to (+) and (–) on the inside of the
battery door.
WARNING: When replacing batteries, always replace the
complete set. Do not mix old batteries with new ones.
Preferably use alkaline batteries.
Operating Tips
• Use only new, high-quality, name brand batteries 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 often to make sure
your laser is calibrated. See Field Calibration Check.
• Before attempting to use the laser, make sure it is positioned
securely, on a smooth, flat surface.
• Always mark the centre 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 (FIG. 1)
The DW089K-KR/DW089CG-KR laser is equipped with a red indicator
light (b), as shown in figure 1. The red indicator light is located to the
left of the on/off buttons (c, d, e).

ENGLISH
15
A flashing red indicator light indicates that the batteries are low and
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 red indicator light will
stay off. (A flashing laser beam is not caused by low batteries; see Out
of Tilt Range Indicator.)

INTENDED USE
The 3 Beam laser DW089K-XJ/DW089CG-XJ has been designed to
project laser lines to aid in professional applications. The tool can be
used for horizontal (level), vertical (plumb) and square alignment. The
applications range from layout of walls and windows to installation of
framing track.
DO NOT use under wet conditions or in presence of flammable liquids
or gases.
The 3 Beam laser is a professional tool. DO NOT let children come
into contact with the tool. Supervision is required when inexperienced
operators use this tool.

ENGLISH
16
OPERATION
To Turn the Laser On and Off (fig. 1)
With the laser off, place it on a flat surface. This model has three
ON/OFF buttons, one for a horizontal laser line (c), one for a vertical
laser line (d) and one for a side vertical laser line (e). Each laser line is
powered on by pressing its ON/OFF button. The laser lines can be
powered one at a time or at the same time. Pressing the ON/OFF
buttons again turns the laser lines off.
Using the Laser
The beams are level or plumb as long as the calibration has been
checked (see Field Calibration Check) and the laser beam is not
flashing (see Out of Tilt Range Indicator).
OUT OF TILT RANGE INDICATOR (FIG. 2)
The DW089K-KR/DW089CG-KR laser is designed to self-level. If the
laser has been tilted so much that it cannot level itself (average > 4° tilt),
it will flash the laser beam. The flashing beam indicates the tilt range has
been exceeded and 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.
SLOPING THE LASER
If the DW089K-KR/DW089CG-KR laser is tilted beyond 15° out of level,
its laser beams will stay on longer between flashes to make it easier to
do angled work.
USING THE PIVOT BRACKET (FIG. 1)
The DW089K-KR/DW089CG-KR laser has a magnetic pivot bracket
(f) 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 (g) allowing the unit to be hung from a nail or screw on any kind of
surface.

ENGLISH
17
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.
USING THE LASER WITH THE WALL MOUNT (FIG. 3)
The laser wall mount (j) offers more mounting options for the DW089
laser. The wall 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 wall
mount is a screw hole (l), allowing the wall mount to be attached to any
surface with a nail or screw.
Once the wall mount is secured, its steel plate provides a surface to
which the magnetic pivot bracket (f) can be attached. The position
of the laser can then be fine-tuned by sliding the pivot bracket up or
down on the wall mount.
ALIGNING THE VERTICAL BEAM – FINE ADJUST (FIG. 4)
The fine adjustment knob (h) on the top of the DW089 is for lining up
the vertical beams. Place the DW089K-KR/DW089CG-KR on a flat
surface and turn the knob to the right to move the beam to the right, or
to the left to move the beam to the left.
Rotating the fine adjustment knob adjusts the entire internal
mechanism, maintaining the 90° angle between the two vertical beams.
LEVELING THE LASER
As long as the DW089K-KR/DW089CG-KR 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.
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 centres.
• When not in use, store the laser in the kit box provided. Do not
store your laser at temperatures below –20 °C (–5 °F) or above
60 °C (140 °F).

ENGLISH
18
• 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.
NOTE: Disassembling the laser level will void all warranties on the
product.
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.
Field Calibration Check
CHECKING ACCURACY – HORIZONTAL BEAM, SCAN DIRECTION (FIG. 5)
Checking the horizontal scan calibration of the laser requires two walls
9 m (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.
TABLE 1 Distance Allowable Distance
Between Walls Between Marks
9.0 m (30') 3.0 mm (1/8")
12.0 m (40') 4.0 mm (5/32")
15.0 m (50') 5.0 mm (7/32")
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 mark the beam position on
the opposing wall directly across from the laser. Always mark the
centre of the beam’s thickness.
3. Pivot the laser to the extreme left (–90 degree position) and mark
the beam position on the opposing wall.
4. Pivot the laser to the extreme right (+90 degree position) and mark
the beam position on the opposing wall.
