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.
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

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-

9.Light indicators - when a battery pack is inserted into the charger, the light will indicate the following: Continuous red: Charging
Continuous green light: Charging is complete
Flashing red: Battery is too hot/cold - Charging will begin when battery reaches correct charging temperature
Flashing red/green: Damaged or faulty battery pack
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.

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.
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 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 informa- tion, visit the RBRC web site at www.rbrc.org.
