Leveling Accuracy for
Horizontal Orientation
A tripod for this operation is suggested. Use a dis-
tance of 100' between the center of the laser and
the wall. Ensure the area is clear of objects and the
laser is level as possible before doing this operation.
This procedure must be performed twice to check the
plane accuracy for both X and Y axes.
1. Mount the laser on a tripod.
2. Turn the laser ON by pressing the power button,
and wait for the self-leveling sequence to finish.
The Leveling Mode Indicator LED will be solid
green when achieved.
3. Mark the center of the beam on the wall (point I).
If the laser is not visible, use a compatible receiver
to find the plane and mark the center point.

wait for self-leveling sequence. Mark the center of
the beam on the wall (point II). Ensure (point II) is
as vertical as possible above or below (point I).
5. Measure the vertical distance, (d) between points
(I) and (II). This is the actual height deviation
of the laser in the axis checked over 200'. The
maximum deviation allowed should be 3/16" at
200' (or 3/32" at 100').

NOTE: If any of the above accuracies are out of spec,
return to an authorized MILWAUKEE service center
for recalibration.

MAINTENANCE
To reduce the risk of injury, always
WARNING
unplug the charger and remove the
battery pack from the charger or tool before
performing any maintenance. Never disassemble
the battery pack, charger, or tool, except as pro-
vided in these instructions. Contact a MILWAUKEE
service facility for all other repairs.
Maintain Laser Level
Maintain tools. If damaged, have the tool repaired
before use at a nearest authorized MILWAUKEE
service center. Accidents may be caused by poorly
maintained tools.
ONE-KEY™
Chemical Burn Hazard.
WARNING
This device contains a
lithium button/coin cell battery. A new
or used battery can cause severe in-
ternal burns and lead to death in as
little as 2 hours if swallowed or enters the body.
Always secure the battery cover. If it does not
close securely, stop using the device, remove the
batteries, and keep it away from children. If you
think batteries may have been swallowed or en-
tered the body, seek immediate medical attention.
Internal Coin Cell Battery
An internal coin cell battery is used to facilitate full
ONE-KEY™ functionality.
To replace the coin cell battery:
1. WARNING! Remove tool's battery to avoid start-
ing the tool.
2. Loosen the screw(s) and open the coin cell bat-
tery door.
3. Remove the old coin cell battery, keep it away from
children, and dispose of it properly.
4. Insert the new coin cell battery (3V CR2032), with
the positive side facing up.
5. Close the battery door and tighten the screw(s)
securely.
To reduce the risk of personal in-
WARNING
jury and damage, never immerse
your tool in liquid or allow a liquid to flow inside
them.
Clean dust and debris from any vents. Keep tool
clean, dry and free of oil or grease. Use only mild
soap and a damp cloth to clean, since certain clean-
ing agents and solvents are harmful to plastics and
other insulated parts. Some of these include gasoline,
turpentine, lacquer thinner, paint thinner, chlorinated
cleaning solvents, ammonia and household deter-
gents containing ammonia. Never use flammable or
combustible solvents around tools.
Cleaning the Aperture Windows
Always wear eye protection. Blow off any loose
particles with clean compressed air. Carefully wipe
the surface with a cotton swab moistened with water.
Calibration and Repairs
For Calibration or Repair, return the tool, bat-
tery pack, and charger to nearest authorized
MILWAUKEE service center.
