Charging the DeWALT Li-ion Battery
1. If the 10.8V Li-ion battery pack is attached to the laser, remove 
it (Figure D).
• Rotate the laser so it is easier to access the battery pack 
(Figure D#1).
• While pressing down on the release button on the battery 
pack (Figure  D #2), pull the battery pack up to unlock 
it from the laser (Figure D#3).
• Pull the battery pack the rest of the way up and out of the 
laser (Figure D#4).
2. Plug the charger cord into an electrical outlet.
3. Slide the battery pack into the charger until it snaps in place 
(Figure F #1). On the charger, the left indicator light will flash 
to let you know the battery is being charged (Figure  F#2).
4. After the battery is fully-charged (the indicator light on the 
charger no longer flashes), press and hold the release button 
on the battery pack (Figure  F #3) and slide the pack out 
of the charger (Figure F#4).
5. Slide the battery pack down in the laser until it snaps in place 
(Figure F#5).
Installing New AA Batteries
CAUTION: 
The AA Starter Pack is designed specically for use 
with DeWALT 10.8V compatible laser products and 
cannot be used with any other tools. Do not attempt 
to modify the product.
 
1. If the AA Starter Pack is attached to the laser, remove it (Figure 
D).
• Rotate the laser so it is easier to access the Starter Pack 
(Figure D#1).
• While pressing down on the release button on the Starter 
Pack (Figure  D #2), pull the Starter Pack up to unlock 
it from the laser (Figure D#3).
• Pull the Starter Pack the rest of the way up and out of the 
laser (Figure D#4).
2. On the AA Starter Pack, lift up the latch to open the battery 
compartment cover (Figure E#1 and #2).
3. Insert four new, high-quality, name brand AA batteries, making 
sure to position the - and + ends of each battery as noted inside 
the battery compartment (Figure  E#3).
4. Push the battery compartment cover down until it snaps in 
place.
5. Slide the Starter Pack down in the laser until it snaps in place 
(Figure E#4).
Viewing the Battery Meter on the Keypad
When the laser is ON, the battery meter on the keypad (Figure  A
#3) indicates how much power remains. Each of the four LEDs 
on the battery meter represents 25% of the power.
• The bottom LED will illuminate and ash when the battery 
level is low (below 12.5%). The laser may continue to operate 
for a short time while the battery power continues to drain, 
but the beam(s) will quickly dim.
• After fresh batteries are installed in the AA Starter Pack, or 
the 10.8V Li-ion battery is charged, 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.
• If all 4 LEDs on the battery meter remain ON, this indicates 
that the laser is not fully powered OFF. When the laser is not 
in use, make sure the Power/Transport Lock switch is placed 
to the LEFT to the Locked/OFF position (Figure  A#1a).
Turning the Laser On
1. Place the laser on a smooth, flat surface.
2. Slide the Power/Transport Lock switch to the right to the 
Unlocked/ON position (Figure  A#1b).
3. Press each button on the keypad (Figure  A#3) to test 
each laser beam setting.
• Press   once to display a horizontal laser line (Figure  A
#3a), a second time to display a vertical laser line (Figure 
A#3b), a third time to display a horizontal line and 
a vertical line (Figure A#3c), and a fourth time to stop 
displaying laser lines.
• Press   once to display dots above, ahead, and below 
the laser (Figure A #3d), a second time to display two 
additional dots from either side of the laser (Figure A
#3e), and a third time to stop displaying dots.
• You can use and  together to display laser dots 
and lines. For example, if you press  three times and 
 twice, the laser will display cross lines and five dots 
(Figure A#3f).
