OPERATION
CAUTION
To reduce the risk of injury, do not
stare at the operating light source.
Using the Lights
1. Insert battery pack or plug into AC power.
2.
Press the power
button to turn on the light.
3.
Press the brightness button to cycle through
High, Medium, and Low.
4. Press the MODE button to select full lighting, main
light, or front/back lights.
5.
Press the power
button to turn OFF the light.
NOTE:
The light will default to the selected brightness
and selected area setting the next time it is turned
on. On battery power, the light will flash to indicate
the battery is reaching end-of-charge.
Rotating the Lights
To rotate the main light, pull the light outward and
rotate up to 210
°counter clockwise or 95° clockwise.
To rotate the front and back lights, pull the lights
outward and rotate up to 30° counterclockwise or
300° clockwise.
USB Power Outlet
This outlet can be used to charge a cell phone,
power an MP3 player or any other device that uses
less that 2.1A of DC electrical current. To turn on the
USB, press the USB power
button. The USB
port will remain on for two hours before turning off
automatically.
NOTE:
Any device that uses more than 2.4A of DC
electrical current will trip a self-resetting overload
and disable the output.
BATTERY
OPERATION
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.

Cold Weather Operation
MILWAUKEE Lithium-Ion battery packs are designed
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.
