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 Height 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
Tripod for easy adjustment.
1. Securely mount the tool within 1' of wall A.
A
B
1'
66'
2. Turn the tool to ON and to Perpendicular
Level & Plumb Points Mode.
3. Direct the front laser beam against the nearest
wall A and allow to self-level. Mark the center of
the laser cross on the wall (point I).
4.
Rotate the tool 180° without changing the height,
allow it to self-level, and mark the center of the
laser cross on the opposite wall B (point II).
• Position the laser and/or wall mount on a stable
surface.
• Use the 1/4"-20 or 5/8"-11 threaded insert to mount
on a tripod.
• Once the level is mounted, use the micro adjustment
knobs to fine tune the laser line.
OPERATION
WARNING
To reduce the risk of injury or tem-
porary effects on vision, do not
look directly into the laser when it is on.
CAUTION
Use of controls or adjustments or
performance of procedures other
than those specified herein may result in hazard
-
ous radiation exposure.
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.
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. Laser Mode Indicator
LED will display, and horizontal level line will imme-
diately be emitted from aperture in the laser housing.
ON
Turns ON the laser and unlocks the pendu-
lum to enable self-leveling.
ON
Turns ON the laser but does not unlock the
pendulum (self leveling is disabled). The
laser lines will flash once every 8 seconds
to indicate that the projected lines are not
level or plumb.
NOTICE:
The ON mode disables self-
leveling and therefore is not intended for
projecting a level or plumb line.
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.
Use the MODE button to cycle through the three
laser modes:
Horizontal Level Line
Vertical Plumb Line & Plumb Points
Perpendicular Level & Plumb Points
The green laser mode indicators will display the
selected mode.
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 when dial is unlocked
and on.
4. The tool is ready once the emitted lines 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
beams will flash rapidly (3 flashes per second).
Relocate or adjust the work surface.
