2. Slide it in until the battery pack is firmly seated in the laser
and ensure that you hear the lock snap into place.
To Remove the Battery Pack from the Laser
1. Press the battery release button

2. Insert battery pack into the charger as described in the
charger section of this manual.
Fuel Gauge Battery Packs (Fig. B)
Some D
WALT battery packs include a fuel gauge which consists
e
of three green LED lights that indicate the level of charge
remaining in the battery pack.
To actuate the fuel gauge, press and hold the fuel gauge

button
. A combination of the three green LED lights will
illuminate designating the level of charge left. When the level of
charge in the battery is below the usable limit, the fuel gauge will
not illuminate and the battery will need to be recharged.
nOTE: The fuel gauge is only an indication of the charge left on
the battery pack. It does not indicate tool functionality and is
subject to variation based on product components, temperature
and end‑user application.
ASSEMBLY AND ADJUSTMENTS
WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories. An accidental
start‑up can cause injury.
Turning the Laser On (Fig. A)

. Pressing the button again turns the laser line off. The
laser lines can be powered one at a time or all at the same time.

Checking Laser Accuracy
The laser tools are sealed and calibrated at the factory. It is
recommended that you perform an accuracy check prior to
using the laser for the first time (in case the laser was exposed to

extreme temperatures) and then regularly to ensure the accuracy
of your work. When performing any of the accuracy checks listed
in this manual, follow these guidelines:
•
Use the largest area/distance possible, closest to the
operating distance. The greater the area/distance, the easier
to measure the accuracy of the laser.
•
Place the laser on a smooth, flat, stable surface that is level in
both directions.
•
Mark the centre of the laser beam.
Field Calibration Check
Horizontal Beam ‑ Scan Direction (Fig. A, F, G, H)
Checking the horizontal pitch calibration of the laser requires
a single wall at least 30' (9 m) 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. Place the laser against the end of the wall on a smooth, flat,
stable surface that is level in both directions (Figure F).
2. Move the Power/Transport Lock switch
the laser ON (Figure A).
3. Press the button to turn on the horizontal beam
4. At least 30' (9 m) apart along the laser beam, mark
5. Turn the laser 180º.
