nOTE: Make sure your battery pack
To Install the Battery Pack into the Tool
Handle
1. Align the battery pack
handle (Fig. B).
2. Slide it into the handle until the battery pack is firmly
seated in the tool and ensure that you hear the lock snap
into place.
To Remove the Battery Pack from the Tool
1. Press the battery release button
battery pack out of the tool handle.
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
e
consists 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 8 . 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.
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 T).

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 centre 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.

Each laser line is powered on by pressing its button on the
keypad 3 . 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.

When the laser is not in use, slide the Power/Transport Lock
switch to the left in the OFF/Locked position.
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
turn 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
and b .
5. Turn the laser 180º.
6. Adjust the height of the laser so the centre of the beam is
aligned with a (Figure G).
7. Directly above or below
