LASER SAFETY
• Keep children and bystanders away while
operating Plumb Laser. Store idle plumb laser
out of the reach of children and do not allow
persons unfamiliar with the tool or these
instructions to operate them.
• Avoid dangerous environments. Do not use
in rain, snow, damp or wet locations. Do not
use in the presence of explosive atmospheres
(gaseous fumes, dust or fl ammable materials)
because sparks may be generated when inserting
or removing battery pack, possibly causing fi re.
WARNING READ ALL SAFETY WARNINGS AND INSTRUCTIONS.
Failure to follow the warnings and instructions may result in electric shock, fi re and/or
serious injury.
Save these instructions - This operator’s manual contains important safety and operating
instructions for the MILWAUKEE 12V 2-Beam Plumb Laser. Before using the Plumb Laser,
read this operator’s manual, your battery pack and charger operator’s manual, and all labels
on the battery pack, charger and Plumb Laser.
• Remove the battery pack before storing. Store
in a cool, dry place. Do not store where tem-
peratures may exceed 120°F (50°C) such as in
direct sunlight, a vehicle or metal building during
the summer.
• Recharge only with the charger specifi ed by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of fi re
when used with another battery pack.
BATTERY USE AND CARE
SERVICE
• Stay alert, watch what you are doing and use
common sense when operating plumb laser.
Do not use while you are tired or under the
infl uence of drugs, alcohol or medication.
A moment of inattention may result in serious

balance at all times. This enables better control
in unexpected situations.

• Avoid exposure to laser radiation. Laser may
emit hazardous radiation.
• Do not point laser at refl ective surfaces. Un-
predictable results may occur.
• Have your Plumb Laser serviced by a qualifi ed

is maintained.
• Do not disassemble. Incorrect reassembly may
result in the risk of electric shock or fi re. If it is dam-
aged, take it to a MILWAUKEE service facility.
• Store in a cool, dry place. Do not store where
temperatures may exceed 120°F (50°C) such as
in direct sunlight, a vehicle or metal building during

Turn the plumb laser on and off by pressing the on/
off button. The power indicator will go on or off. The
power indicator will blink when the battery pack has
less than 1 hour of run time left.
Place the plumb laser in the desired location. If
the laser beams begins to fl ash, the tool is more
than 4° out of level. Adjust the plumb laser until
the laser beams do not fl ash. NOTE: The plumb
laser is self leveling within 4° - it does not need to
be perfectly fl at.

MAINTENANCE
WARNING To reduce the risk of per-
sonal injury and damage, never immerse your
tool, battery pack or charger in liquid or allow
a liquid to fl ow inside them.
WARNING To reduce the risk of injury,
always unplug the charger and remove the
battery pack from the charger or tool before
performing any maintenance. Never disas-
semble the tool, battery pack or charger.
Contact a MILWAUKEE service facility for
ALL repairs.
Maintaining Tool
Keep your tool, battery pack and charger in good re-
pair by adopting a regular maintenance program.
If the tool does not start or operate at full power
with a fully charged battery pack, clean the contacts
on the battery pack. If the tool still does not work
properly, return the tool, charger and battery pack,
to a MILWAUKEE service facility for repairs.
Checking Accuracy of the Plumb Laser
With a ceiling height of 10’ to 20', turn on the
plumb laser.
Step A - Mark the location of the top and bottom
beams.
Step B - Rotate the plumb laser 180° and line up
the bottom beam with the mark made in Step A.
The top beam should line up with the mark from
Step A. If they do not line up, the laser is out of
plumb. If this happens, contact a MILWAUKEE
service facility.

Clean the laser windows with a cotton swab dipped
in alcohol to keep them clean and clear. Remove
battery pack before cleaning.
