4. You may charge a partially used pack whenever you
desire with no adverse effect on the battery pack.
Charger Cleaning Instructions
WARNING: Shock hazard. Disconnect the charger
from the AC outlet before cleaning. Dirt and grease
may be removed from the exterior of the charger using
a cloth or soft non-metallic brush. Do not use water or
any cleaning solutions.
Wall Mounting
Some D
WALT chargers are designed to be wall mountable
e
or to sit upright on a table or work surface. If wall mounting,
locate the charger within reach of an electrical outlet, and
away from a corner or other obstructions which may impede
air flow. Use the back of the charger as a template for the
location of the mounting screws on the wall. Mount the
charger securely using drywall screws (purchased separately)
at least 1" (25.4 mm) long, with a screw head diameter of
0.28–0.35" (7–9 mm), screwed into wood to an optimal
depth leaving approximately 7/32" (5.5 mm) of the screw
exposed. Align the slots on the back of the charger with the
exposed screws and fully engage them in the slots.

Installing and Removing the Battery Pack
(Fig. D)
nOTE: For best results, make sure your battery pack is
fully charged.
To install the battery pack
battery pack with the rails inside the tool's handle and slide it
into the handle until the battery pack is firmly seated in the
tool and ensure that it does not disengage.
To remove the battery pack from the tool, press the release
button

and firmly pull the battery pack out of the tool
handle. Insert it into the charger as described in the charger
section of this manual.
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, flat stable surface that
is level in both directions.
•
To increase beam visibility, use a Laser Target Card
(Figure V).
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.

When the laser is not in use, slide the Power/Transport Lock

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 center of the laser beam.
FIELD CALIBRATION CHECK
Horizontal Beam - Scan Direction
(Fig. A, H, I, J)
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 H).
2. Move the Power/Transport Lock switch
turn the laser ON (Figure A).
3. Press the button to turn on the horizontal beam
