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 fl ash slowly.

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
fl ash 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 fl ash. 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 fl ash in an
alternating pattern and the tool will not run. Allow
the battery to cool down.

Disposing of MILWAUKEE Li-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 recy-
cling agency in your area for recycling locations.
Even discharged battery packs contain some en-
ergy. Before disposing, use electrical tape to cover
the terminals to prevent the battery pack from short-
ing, which could cause a fi re 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 Offi ce/Service Center or the

participating retailer nearest you. For more informa-
tion, visit the RBRC web site at www.rbrc.org.

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 corrosion of terminals may occur. As with
other battery pack types, permanent capacity
loss can result if the pack is stored for long pe-
riods 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.

WARNING

To reduce the risk of injury

or explosion, never burn or inciner-

ate a battery pack even if it is damaged, dead
or completely discharged. When burned, toxic
fumes and materials are created.
