Turning On/Off
To turn on the laser and unlock the pendulum, rotate
the On/Off dial to the desired position. The remaining
battery life will be displayed.
WARNING!
Do not look
directly into laser apertures.
ON Turns ON the laser and unlocks the pendu-
lum to enable self-leveling.
OFF Turns OFF the laser and locks the pen-
dulum. When not in use, turn off the tool
and store the Laser Level in the protective
carrying case.
Using the Laser Level
1. For best results, place the tool on a work surface
that is:
• sturdy
•
level (within 4 degrees of true level)
• free of vibrations
•
90° to the work area
2.
Turn on the tool.
3.
The tool will self-level when placed on surfaces
within 4 degrees of true level.
4. The tool is ready once the emitted points are con-
tinuous and no longer moving on the work surface.
5.
If the tool cannot achieve a level state (i.e., the
work surface is > 4 degrees off true level), the laser
points will flash rapidly (3 flashes per second).
Relocate or adjust the work surface.
Troubleshooting
If the tool does not turn on:
• Ensure battery is installed properly. Fuel gauge
should indicate remaining charge when correctly
installed.
• Ensure battery is charged.
• Ensure the tool's internal temperature is within
specified operating ranges. If stored in excessive
heat or cold, allow at least 2 hours to acclimate to
ambient temperature before turning on the tool.
If problem persists, please contact a MILWAUKEE
service facility for support.
ACCURACY FIELD
CHECK
NOTICE
Perform the Accuracy Field Check
procedure immediately upon unboxing
of each new Laser Level and before exposure to
jobsite conditions. See "Accuracy Field Check"
for information. Should any deviation from listed
product accuracy be found, please con
-
tact a MILWAUKEE service facility. Failure to do
so could result in rejection of warranty claim.
Influences on Accuracy
Ambient temperature gradients can impact laser
accuracy. For accurate and repeatable results, the
following procedure should be conducted with the
laser elevated off the ground and placed in the center
of the working area.
Abusive treatment of the Laser Level, such as exces-
sive impacts from drop, can also lead to deviations
in product accuracy.
Therefore, it is recommended to conduct the Field
Check procedure after any impact or before complet-
ing any critical jobs.
Horizontal Leveling Accuracy
A free measuring distance of approximately 66' on a
firm surface between two walls or structures A and
B is required for this check.
It is also suggested to mount the Laser Level to a
commercially available Tripod for easy adjustment.
1. Securely mount the tool within 1' of wall A.
2.
Turn the tool to ON.
3.
Direct the front laser beam against the nearest
wall A and allow to self-level. Mark the center of
the laser point on the wall (point I).

4.
Rotate the tool 180° without changing the height,
allow it to self-level, and mark the center point of
the laser point on the opposite wall B (point II).

5.
Move the tool within 1' of wall B. Turn on the tool
and align the front laser point in the general direc-
tion of point II on wall B.
6. Adjust the height of the tool (using the tripod or by
adding shims, if required) to align the center point
of the laser beam directly onto point II on wall B.
Allow the tool to self-level.

7.
Rotate the tool 180° without changing the height,
allow it to self-level, and mark the center point of
the laser beam on wall A (point III). Point III should
be aligned as vertically above or below point I on
wall A as possible.
