procedure immediately upon unboxing
of each new laser and before exposure to jobsite
conditions. See "Accuracy Field Check" for
information. Should any deviation from listed
product accuracy be found, please contact an

Turning the Rotary Laser ON/OFF
• To turn the laser ON, press the power button. When
powered on, the laser will begin the leveling se-
quence. Once level and ready to use, the Leveling
Mode Indicator LED will become solid green.
• To turn the laser OFF, press the power button. The
laser diode will turn off, the head will stop rotating,
and all LEDs will turn off.
Rotational Mode
When the laser initially turns on, the laser will auto-
matically start to self-level. The laser head will rotate
at 600 RPM, and the laser beam will become visible.
Auto-Leveling Mode
When the laser initially turns on, the laser will au-
tomatically start to self-level. The Leveling Mode
Indicator LED will begin flashing green.
• During the leveling process, the Bump Alarm will not
be active. When the laser is leveled, the Leveling
Mode Indicator LED will be solid green, and the laser
head will start to rotate. The laser will be ready for
use.
• If the leveling process fails by the one-minute timer
or is out of the leveling range, the Leveling Mode
Indicator LED flashes red, the laser diode turns off
and stops rotating, and an audible tone will sound.
NOTE: If the laser fails to level, ensure the laser is
on a stable and flat surface. This error occurs when
the working surface causes the laser to be outside
the leveling range. After, try pressing the Leveling
button or power cycling the laser to trigger a relevel.
If the problem persists, please contact an authorized
MILWAUKEE service center for support.
