ASSEMBLY
WARNING: Prior to assembly and
adjustment, always remove the battery
pack. Always switch off the tool before
inserting or removing the battery pack.
WARNING: Use only D
packs and chargers.
Inserting and Removing the
Battery Pack from the Tool (fi g. 2)
TO INSTALL THE BATTERY PACK
1. Release latch (c) to open the hatch door (a).
Insert the battery pack (n).
CAUTION: The laser will operate even
if battery door is not fully latched. To
secure the battery, always ensure
battery door is closed and latched.
2. Slide the battery pack in firmly.
3. Close the hatch door and fasten latch.
TO REMOVE THE BATTERY PACK
1. Release latch to open the hatch door.
2. Remove the battery pack.
3. Insert battery pack into the charger to recharge
it. (Refer to Charging Procedure.)
Setting Up the Laser (fi g. 3)
The laser facilitates various set-ups, making it useful
for several applications.
TRIPOD SET-UP (FIG. 3)
1. Position the tripod securely and set it to the
desired height.
2. Make sure that the top of the tripod is roughly
level. The laser will self-level only if the top of the
tripod is within ± 5˚ of level. If the laser is set up
too far out of level, it will beep when it reaches
the limit of its leveling range. No damage will be
done to the laser, but it will not operate in an
"out of level" condition.
3. Secure the laser to the tripod by screwing the
threaded knob (s) on the tripod into the female
thread (t) on the bottom of the laser.
NOTE: Be sure that the tripod you are working
with has a 5/8"–11 threaded screw to ensure
secure mounting.
4. Turn the laser on.

OPERATION
• To extend battery life per charge, turn the laser
off when it is not in use.
WALT battery
E
• To ensure the accuracy of your work, check
the laser calibration often. Refer to Field
Callibration Check under Laser Maintenance.
• Before attempting to use the laser, make sure
the tool is positioned on a relatively smooth,
secure surface.
• Always mark the centre of the laser line or
dot. If you mark different parts of the beam at
different times you will introduce error into your
measurements.
• To increase working distance and accuracy, set
up the laser in the middle of your working area.
• When attaching to a tripod or wall, mount the
laser securely.
• To increase beam visibility, wear Laser
Enhancement Glass es and/or use a Laser
Target Card to help find the beam.
• Extreme temperature changes can cause
movement or shifting of building structures,
metal tripods, equipment, etc., which can affect
accuracy. Check your accuracy often while
working.
• If the laser is dropped or suffers a sharp blow,
have the calibration system checked by a
qualified service centre before using the laser.
Laser Control Panel (fi g. 1)
The laser is controlled by the power button (e). Three
LED indicator lights are on the control panel: power
(f), X-axis leveling (g), Y-axis leveling (h).
TURNING THE LASER ON (FIG. 1)
1. Insert the fully charged battery pack. Be sure
that the battery door is securely latched.
2. Gently press the power button (e) to power the
laser on. The power LED light (f) will illuminate.
If the laser is out of level, the X-axis (g) and/or
Y-axis (h) leveling lights will flash until the laser
is level.
NOTE: The head will begin or resume rotation once
the laser is level.
TURNING THE LASER OFF
Gently press the power button to turn the laser
off. The power LED indicator light will no longer be
illuminated.
WARNING: Always observe the safety
instructions and applicable regulations.
