the charger, the light will indicate the following situations:
Continuous red light: Charging
Continuous green light: Charging is complete
Flashing red light: Battery pack is too hot or too cold - Charging will begin
automatically when battery reaches correct charging
temperature
Flashing red and green light: Damaged or faulty battery pack

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 stay lit for two seconds.
MILWAUKEE LITHIUM-ION BATTERY PACK OPERATION
OFF, immediately reduce pressure on the
application or release the trigger. If the tool
does turn off, release the trigger to reset. If
this happens repeatedly, the battery pack
will shut down and need to be placed on the
charger to reset.
Under extreme circumstances, the internal
temperature of the battery could become too
high. If this happens, the battery pack will
shut off. Remove the battery pack from the
tool and place it on the charger to reset it.
To determine if the battery pack needs to
be placed on the charger to be reset, press
the fuel gauge button. If the bottom gauge
fl ashes once, the battery must be reset on
the charger.
Cold Weather Operation
The MILWAUKEE Lithium-Ion battery pack
can be used in temperatures down to -4°F.
When the battery pack is very cold, put the
battery pack 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 cas-
ing 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, per-
manent capacity loss can result if the pack
is stored for long periods of time at high tem-
peratures (over 120° F). MILWAUKEE Lith-
ium-Ion battery packs maintain their charge
during storage longer than other battery pack
types. After about six months of storage,
charge the pack as normal.

Approximate Run
Time Remaining
NOTE: If the Fuel Gauge doesn't appear to
be working, place the battery pack on the
charger and charge as needed.
Unlike other 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 to you that the battery
pack is at the end of its run time and needs
to be charged, power to the tool will drop
quickly. When this happens, remove the tool
from the workpiece and charge the battery
pack as needed.
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 moni-
tors 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. In these situations, the
tool will "buzz" for about 2 seconds before it
turns OFF. To prevent the tool from turning
