Troubleshooting
• Ensure batteries are inserted correctly according to
the +/- polarity marked in the compartment.
• Replace batteries that may be at the end of life.
• Ensure the tool's internal temperature is within speci-
fied 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 the receiver freezes, press and hold the power but-
ton for 15 seconds or remove the batteries to reset.
If problem persists, please contact an authorized
MILWAUKEE service facility for support.
ACCURACY FIELD CHECK
Perform the Accuracy Field Check
NOTICE
procedure immediately upon unboxing
of each receiver and before exposure to jobsite
conditions. See "Accuracy Field Check" for in-
formation. Should any deviation from listed product
accuracy be found, please contact an authorized
MILWAUKEE service center. Failure to do so could
result in rejection of warranty claim.
Influences on Accuracy
Sunlight or other extreme lighting conditions can
adversely impact accuracy. For best results, use
indoors or avoid direct sunlight. Abusive treat-
ment of the laser level receiver, such as exces-
sive impacts from drops, can lead to deviations in
product accuracy. Therefore, it is recommended
to conduct the Field Check procedure after any
impact or before completing any critical jobs.
For best results, use MILWAUKEE Lasers.
Receiver Accuracy Check Procedure
1. Set up a compatible laser 30' using a flat wall.
2. Ensure the laser source is self-leveled and
perpendicular to the wall.
3. Place the receiver flat on a wall directly in front of
the laser source and slightly below the projected
laser line.
4. Keeping the bottom of the receiver parallel with
the ground, raise the recevier past the center mark
until the down arrow appears on the LCD screen.
5. Lower the receiver until the center line appears.
6. Mark a line on the wall – Point "I".
7. Continue to lower the receiver until the up arrow
appears.
8. Raise the receiver until the center line appears.
9. Mark a line on the wall – Point "II".
10. Measure the distance between Point "I" and Point
"II" – divide by 2. After completion, compare this
to the Receiver Accuracy table in the "Setting
Accuracy" section.

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-

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 Sensor Window
Blow off loose particles with clean compressed air.
Carefully wipe the surface with a cotton swab moist-
ened with water.
For repairs, return the tool, battery pack and charger
to the nearest authorized service center.
