IMPORTANT SAFETY INSTRUCTIONS
WARNING READ AND UNDESTAND ALL INSTRUCTIONS. Failure to follow all
instructions listed below, may result in electric shock, fire and/or serious
personal injury.
SAVE THESE INSTRUCTIONS
- SAVE THESE INSTRUCTIONS – THIS OPERATOR’S MANUAL CONTAINS IMPORTANT SAFETY AND OPERATING INSTRUCTIONS FORMILWAUKEE ® LI-ION BATTERIES.
- BEFORE USING THE BATTERY PACK, READ THIS INSTRUCTION SHEET, YOUR TOOL AND CHARGER OPERATOR’S MANUALS, AND ANYLABELS ON THE BATTERY PACK, CHARGER AND TOOL.
- CAUTION TO REDUCE THE RISK OF INJURY, CHARGE ONLY MILWAUKEE® BATTERIES IN MILWAUKEE® LITHIUM-ION BATTERY HARGERS OR APPROPRIATE MILWAUKEE® EQUIPMENT CAPABLE OF CHARGING MILWAUKEE® BATTERIES. CHARGE MILWAUKEE® 18V LITHIUM-ION BATTERIES ONLY IN MILWAUKEE® 18V LITHIUM-ION COMPATIBLE CHARGERS.Other types of chargers may cause personal injury or damage. Do not wire a battery pack to a power supply plug or car cigarette lighter. Batteries will be permanently disabled or damaged.
- USE MILWAUKEE ® 18V LITHIUM-ION BATTERIES ONLY ON MILWAUKEE ® 18V LITHIUM-ION TOOLS. Use with other tools may result in a risk of fire, electric shock or personal injury.
- AVOID DANGEROUS ENVIRONMENTS. Do not charge battery pack in rain, snow, damp or wet locations. Do not use battery pack or charger in the presence of explosive atmospheres (gaseous fumes, dust or flammable materials) because sparks may be generated when inserting or removing battery pack, possibly causing fire.
- CHARGE IN A WELL VENTILATED AREA. Do not block charger vents. Keep them clear to allow proper ventilation. Do not allow smoking or open flames near a charging battery pack. Vented gases may explode.
- DO NOT CRUSH, DROP, OR DAMAGE BATTERIES. Do not use a battery pack or charger that has received a sharp blow, been dropped, run over, or damaged in any way (e.g., pierced with a nail, hit with a hammer, stepped on).
- DO NOT DISASSEMBLE. Incorrect reassembly may result in the risk of electric shock, fire or exposure to battery chemicals. If it is damaged, take it to a MILWAUKEE ® service facility.
- BATTERY CHEMICALS CAUSE SERIOUS BURNS. Never allow contact with skin, eyes, or mouth. If a damaged battery pack leaks battery chemicals, use rubber or neoprene gloves to dispose of it. If skin is exposed to battery fluids, wash with soap and water and rinse with vinegar. If eyes are exposed to battery chemicals, immediately flush with water for 20 minutes and seek medical attention. Remove and dispose of contaminated clothing.
- DO NOT SHORT CIRCUIT. A battery pack will short circuit if a metal object makes a connection between the positive and negative contacts on the battery pack. Do not place a battery pack near anything that may cause a short circuit, such as coins, keys or nails in your pocket. A short circuited battery pack may cause fire and personal injury.
- STORE YOUR BATTERY PACK AND CHARGER IN A COOL, DRY PLACE. Do not store battery pack where temperatures may exceed 50°C (120°F) such as in direct sunlight, a vehicle or metal building during the summer.
ADDITIONAL BATTERY SAFETY RULES
WARNING To reduce the risk of fire, personal injury, and product damage
due to a short circuit, never immerse your tool, battery pack or charger in
fluid or allow a fluid to flow inside them. Corrosive or conductive fluids,
such as seawater, certain industrial chemicals, and bleach or bleach-
containing products, etc., can cause a short circuit.
WARNING Do not charge non-rechargeable batteries.

Fuel Gauge
Use the Fuel Gauge to deter mine the battery pack’s re-maining runtime. Press the Fuel Gauge button to dis- play 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.
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® Li-Ion battery packs deliver
fade-free power for their entire runtime. 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.
Cold Weather Operation
MILWAUKEE® Li-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.
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 temperature 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.
| Fuel Gauge Lights | Diagnosis | Solution |
|---|---|---|
| Lights 1 -4 Solid | Remaining runtime | Continue working |
| 1 Light, flashing slowly | Less than 10% run time left | Prepare to charge pack |
| 1 Light, flashing quickly | End of discharge | Charge pack |
| Lights 1-4, flashing quickly | Current draw too high | Release trigger and |
restart, reduce pressure
Lights 1 &3 / 2&4, flashing alternatingly| Battery temperature too high|
Release trigger and allow battery to cool
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 batteries at room temperature away from moisture. Do not store in damp
locations where corrosion of terminals may occur. As with other battery types,
permanent capacity loss can result if the battery pack is stored for long
periods of time at high temperatures (over 50°C). MILWAUKEE ® Lithium-Ion
batteries maintain their charge during storage longer than other battery
types. After about six months of storage, charge the battery pack as normal.
Disposing of MILWAUKEE ® Lithium-Ion Batteries
Disposing of MILWAUKEE® Lithium-Ion Batteries MILWAUKEE ® Lithium-Ion batteries are more environmentally friendly than some other types of power tool batteries (e.g., nickel-cadmium). Always dispose of your battery pack according to federal, state and local regulations. Contact a recycling agency in your area for recycling locations. Even discharged batteries 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.
WARNING To reduce the risk of injury 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.
