age, securely mount/attach the
laser before starting an operation. Injury/damage
may occur if the laser falls.
Mounting/Adjusting the Laser Level
The pivot bracket can be used to mount the laser
level in multiple ways:
• Use the embedded magnets to secure the laser
level to steel studs, steel beams, etc.
• Use the keyhole slot to hang the laser level on the
wall with a nail or screw.
• Set the laser level on a flat surface.
• 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 vertical lines.

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. Power on indicator will
display, and horizontal level line will immediately be
emitted from aperture in the laser housing.

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

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 and press the desired Plane
Selector button(s).
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
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.
