User Manual
• Carefully follow all instructions and warnings on the battery label
and package and accompanying Battery Safety Leaflet.
• Always insert batteries correctly with regard to polarity (+ and –),
marked on the battery and the equipment.

• Do not charge disposable batteries.
• Do not mix old and new batteries. Replace all of them at the same
time with new batteries of the same brand and type.
• Remove dead batteries immediately and dispose of per local codes.
• Do not dispose of batteries in fire.
• Keep batteries out of reach of children.
• Remove batteries when the device is not in use
• Use only the charger specified for your rechargeable battery pack.
Personal Safety
• Stay alert, watch what you are doing and use common sense when
operating a laser tool. Do not use tool while tired or under the
influence of drugs, alcohol, or medication. A moment of inattention
while operating power tools may result in serious personal injury.
• Do not overreach. Keep proper footing and balance at all times.
Proper footing and balance enables better control of the tool in
unexpected situations.
• Use safety equipment. Always wear eye protection. Dust mask,
non-skid safety shoes, hard hat, or hearing protection may be
required for appropriate conditions.
Tool Use and Care
• Do not use tool if switch does not turn it on or off. Any tool that
cannot be controlled with the switch is dangerous and must be
repaired.
• Store idle tools out of reach of children and other untrained
persons. Tools are dangerous in the hands of untrained users.
• Use only accessories that are recommended by the manufacturer
for your model. Accessories that may be suitable for one tool,
may become hazardous when used on another tool.
Service
• Tool service must be performed only by qualified repair personnel.
Service or maintenance performed by unqualified personnel could
result in a risk of injury.
• When servicing a tool, use only identical replacement parts. Follow
instructions in the Maintenance section of this manual. Use of
unauthorized parts or failure to follow Maintenance Instructions
may create a risk of electric shock or injury.

Operating Tips

• Use only new, high-quality, name brand AA batteries or specified
rechargeable DEWALT 12V 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 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 DW088LR and DW088LG lasers are equipped with a battery
gauge as shown in . The battery gauge indicates remaining
5B
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
2 5
(See Figure , )
With the laser off, place it on a flat surface. This model has a
B C
pendulum locking switch and a keypad to activate the
laser beams with two ON/OFF buttons; one for a horizontal
D E
laser line and one for a vertical laser line . Each laser
line is powered on by moving the pendulum lock switch
the UNLOCKED/ON position and pressing the required ON/OFF
button on the keypad. 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. The pendulum locking switch disables
the lasers as well as locking the pendulum, and should always be
placed in the LOCKED/OFF 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 )
3
G
The lasers have a magnetic pivot bracket permanently
attached to the units. 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
H
keyhole slot allowing the unit to be hung from a nail or screw
on any kind of surface. 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 CEILING Mount
(See Figure )
5
The laser ceiling mount J (if included) offers more mounting
options for the laser. The ceiling mount has a clamp 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
ceiling mount to be attached to any surface with a nail or screw.
Once the ceiling mount is secured, its steel plate provides a
G
surface to which the magnetic pivot bracket
The position of the laser can then be fine-tuned by sliding the
magnetic pivot bracket up or down on the wall mount.
B to
Using the Lasers with Accessories
The lasers are equipped with 1/4 - 20 and 5/8 -11 female threads
on the bottom of the unit. This thread is to accommodate current
or future DeWALT accessories. Only use DeWALT accessories
specified for use with this product. Follow the directions included
with the accessory.
CAUTION:
The use of any other accessory not recommended for use
with this tool could be hazardous.
If you need any assistance in locating any accessory, please
contact DeWALT Industrial Tool Co., 701 East Joppa Road,
Towson, MD 21286 or call 1-800-4-DeWALT (1-800-433-9258)
Leveling the Lasers
As long as the lasers are properly calibrated, the lasers are
self-leveling. Each laser is calibrated at the factory to find level as
long as it is positioned on a flat surface within ± 4° of level. No
manual adjustments must be made.
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.
