To indicate low battery level, the laser beams will
blink quickly 3 times, followed by 4 seconds of solid
on (repeating). Charge the battery.
To charge the battery with laser powered off:
1. Plug your USB cable into a power source such as
an AC wall adaptor, computer, or car port.
2. Lift the rubber cover to expose the micro USB port.
Insert the micro USB plug into the micro USB port.
Users may experience longer charge times from
laptops and other power sources.
3. The indicator light will display the charging status:
Pulsing Red: Charging, 0-49% charged
Pulsing Yellow: Charging, 50-99% charged
Solid Green: 100% Charged.
To charge the battery with laser in use, follow
steps1-2 listed in the section above. The indicator
light will display the charging status:
Pulsing Red (Continuous)
Upon removal of USB cable, fuel gauge will dis-
play current battery life.
Flashing Red/Green: USB cable inserted without
battery installed & Damaged or Faulty Battery. If
the light indicator flashes red and green, check
that the battery is fully seated into the bay. Re-
move the battery and reinsert. If the light contin-
ues to flash red and green, the battery may be
extremely hot or cold, or wet. Allow the battery to
cool down, warm up, or dry out and then reinsert.
If the problem persists, contact a MILWAUKEE
service facility.
NOTE:
When the laser level is charged during
USE, the indicator light will be Pulsing Red (Con-
tinuous). When the USB cable is disconnected,
the fuel gauge will display current battery life.
WARNING
To reduce the risk of injury or dam-
age, securely mount/attach the
laser before starting an operation. Injury/damage
may occur if the laser falls.
Mounting/Adjusting the Laser Level
The adjustable clearance bracket can be used to
mount the laser level in multiple ways:
• Use the embedded magnets to secure the laser
level to framing 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 ¼" - 20 threaded insert to mount on a tripod.
Adjustable Clearance Bracket
Hold the bracket and adjust the laser up or down until
the desired clearance is achieved.
OPERATION
WARNING
To reduce the risk of injury or tem-
porary effects on vision, do not
look directly into the laser when it is on.
CAUTION
Use of controls or adjustments or
performance of procedures other
than those specified herein may result in hazard
-
ous radiation exposure.
NOTICE
Perform the Accuracy Field Check
procedure immediately upon unboxing
of each new Laser Level and before exposure to
jobsite conditions. See "Accuracy Field Check"
for information.
BATTERY
WARNING
To reduce the risk of fire, personal
injury, and product damage due to
a short circuit, never immerse your tool, battery
pack or charger in fluid or allow a fluid to flow
inside them. Corrosive or conductive fluids, such
as seawater, certain industrial chemicals, and
bleach or bleach containing products, etc., can
cause a short circuit.
Maintenance and Storage
Do not expose your battery or cordless tools to water or
rain, or allow them to get wet. This could damage the
tool and battery. Do not use oil or solvents to clean or
lubricate your battery. The plastic casing will become
brittle and crack, causing a risk of injury.
Store batteries at room temperature away from mois-
ture. Do not store in damp locations where corrosion
of terminals may occur. As with other battery types,
permanent capacity loss can result if the pack is stored
for long periods of time at high temperatures (over 120°
F). MILWAUKEE Li-Ion batteries maintain their charge
during storage longer than other battery types. After
about a year of storage, charge the battery as normal.
WARNING
To reduce the risk of injury or ex-
plosion, never burn or incinerate a
battery pack even if it is damaged, dead or com
-
pletely discharged. When burned, toxic fumes
and materials are created.
Disposing of MILWAUKEE Li-Ion Battery
MILWAUKEE Li-Ion batteries are more environmen-
tally friendly than some other types of power tool
batteries. Always dispose of your battery according
to federal, state and local regulations. Contact a
recycling agency in your area for recycling locations.
Even discharged batteries contain some energy.
Before disposing, use electrical tape to cover the
terminals to prevent the battery from shorting, which
could cause a fire or explosion.
RBRC Battery Recycling Seals
The RBRC™ Battery Recycling Seals (see "Symbol
-
ogy") on your batteries indicate that MILWAUKEE
has arranged for the recycling of that battery with
the Rechargeable Battery Recycling Corporation
(RBRC). At the end of your battery's useful life,
return the battery to a MILWAUKEE Branch Office/
Service Center or the participating retailer nearest
you. For more information, visit the RBRC web site
at www.rbrc.org.
