Installing New AA Batteries
CAUTION:
The AA Starter Pack is designed specifi cally
for use with DEWALT 12V 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.
• Rotate the laser so it is easier to access the
Starter Pack (Figure
C 1
).
• While pressing down on the release button on the
Starter Pack (Figure
C 2
), pull the Starter Pack
up to unlock it from the laser).
• Pull the Starter Pack the rest of the way up and
out of the laser (Figure
C 3
).
2.
On the AA Starter Pack, lift up the latch to open the
battery compartment cover (Figure
A 1
and
A 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
A 3
).
4.
Push the battery compartment cover down until it
snaps in place (Figure
A 4
).
5.
Slide the Starter Pack down in the laser until it
snaps in place (Figure
A 5
).
Viewing the Battery Meter
When the laser is ON, the battery meter on the keypad
(Figure
F 7
) 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 fl 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 12V MAX 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
F 2
).
Operating Tips
• To extend battery life per charge, turn the laser off
when it is not in use.
• To ensure the accuracy of your work, check the
laser calibration often. Refer to Checking Laser
Accuracy.
• Before attempting to use the laser, make sure it is
positioned securely, on a smooth, fl at stable surface
that is level in both directions.
• To increase beam visibility, use a Laser Target Card
(Figure
D
) and/or wear Laser Enhancement Glass es
(Figure
E
) to help find the beam.
CAUTION:
To reduce the risk of serious injury, never stare
directly into the laser beam with or without
these glasses. Refer to Accessories for
important information.
• Always mark the center of the beam created by the
laser.
• Extreme temperature changes can cause movement
or shifting of building structures, metal tripods,
equipment, etc., which can effect accuracy. Check
your accuracy often while working.
• If the laser has been dropped, check to make sure
your laser is still calibrated. Refer to Checking Laser
Accuracy.
