Fuel gauge
Use the Fuel Gauge to determine the battery pack's
remaining run time. Press the Fuel Gauge button to
display the lights. The Fuel Gauge will light up for
2-3 seconds. When less than 10% of charge is left,
1 light on the fuel gauge will flash slowly.

Time Remaining
NOTE: If the Fuel Gauge doesn't appear to be
working, place the battery pack on the charger and
charge as needed.
Compared to NiCd battery pack types, MILWAUKEE
Lithium-Ion battery packs deliver fade-free power
for their entire run time. The tool will not experience
a slow, gradual loss of power as you work. To signal
the end of discharge, 1 light on the fuel gauge will
flash quickly for 2-3 seconds and the tool will not
run. Charge the battery pack.
NOTE: Immediately after using the battery pack,
the Fuel Gauge may display a lower charge than
it will if checked a few minutes later. The battery
cells "recover" some of their charge after resting.
battery Pack Protection
To protect itself from damage and extend its life, the
battery pack’s intelligent circuit monitors current draw
and temperature. In extremely high torque, binding,
stalling, and short circuit situations, the battery pack
will turn OFF the tool if the current draw becomes
too high. All the fuel gauge lights will flash. Release
the trigger and restart.
Under extreme circumstances, the internal tem-
perature of the battery could become too high. If
this happens, the fuel gauge lights will flash in an
alternating pattern and the tool will not run. Allow
the battery to cool down.
Disposing of milWaukee Lithium-Ion battery
Packs
MILWAUKEE Lithium-Ion battery packs are more
environmentally friendly than some other types of
power tool battery packs (e.g., nickel-cadmium).
Always dispose of your battery pack according to
federal, state and local regulations. Contact a re-
cycling agency in your area for recycling locations.
Even discharged battery packs contain some
energy. Before disposing, use electrical tape to
cover the terminals to prevent the battery pack from
shorting, which could cause a fire or explosion.
RbRc battery Recycling Seals
The RBRC™ Battery Recycling Seals (see "Sym-
bology") on your tool battery packs indicate that
MILWAUKEE has arranged for the recycling of
that battery pack with the Rechargeable Battery
Recycling Corporation (RBRC). At the end of your
battery pack's useful life, return the battery pack to
a MILWAUKEE Branch Office/Service Center or the
participating retailer nearest you. For more infor-
mation, visit the RBRC web site at www.rbrc.org.
Warning
To reduce the risk of in-
jury or explosion, never burn or incinerate
a battery pack even if it is damaged, dead or
completely discharged. When burned, toxic
fumes and materials are created.

cold Weather Operation
MILWAUKEE Lithium-Ion battery packs are de-
signed to operate in temperatures below freezing.
When the battery pack is too cold, it may need to
warm up before normal use. Put the battery on a
tool and use the tool in a light application. It may
“buzz” for a short time until it warms up. When the
buzzing stops, use the tool normally.
Maintenance and Storage
Do not expose your battery pack or cordless tools
to water or rain, or allow them to get wet. This could
damage the tool and battery pack. Do not use oil
or solvents to clean or lubricate your battery pack.
The plastic casing will become brittle and crack,
causing a risk of injury.
Store battery packs at room temperature away from
moisture. Do not store in damp locations where cor-
rosion of terminals may occur. As with other battery
pack types, permanent capacity loss can result if
the pack is stored for long periods of time at high
temperatures (over 120° F). MILWAUKEE Lithium-
Ion battery packs maintain their charge during
storage longer than other battery pack types. After
about a year of storage, charge the pack as normal.
