Only charge in a well ventilated area and within the Recommended Ambient Charging Temperature range. Do not block vents; keep them clear for proper ventilation. Do not allow smoking or open flames near a charging battery. Vented gases may explode.
Maintain charger cord. Pull plug rather than cord to unplug. Never carry charger by its cord. Keep cord from heat, oil and sharp edges. Ensure cord will not be stepped on, tripped over, damaged, or stressed. Do not use charger with damaged cord or plug.
Replace damaged cords immediately.
Avoid using an extension cord when possible. When unavoidable, use an extension cord in good electrical condition with the proper wire gauge and length for the current rating of the charger. The pin size and shape must match the pins on the charger cord.
Charger is rated for 120 V AC ONLY. Charger must be plugged into an appropriate receptacle.
Use only recommended attachments.
Unplug charger and remove batteries when not in use.
Always unplug charger before cleaning or maintenance. Do not allow water to flow into AC/DC plug. Use a Ground Fault Circuit Interrupter (GFCI) to reduce shock hazards.
Do not burn, incinerate, or expose batteries to fire or excessive temperatures above 265°F (130°C). Batteries may explode. Toxic fumes and materials are created when batteries are burned.
Do not crush, drop, shred, modify, or damage battery. Always securely contain batteries during transport. Do not use a battery 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, in a vehicle accident). Do not use or charge batteries that appear damaged or swollen, or are not functioning properly. Damaged or modified batteries may exhibit unpredictable behavior.
Do not disassemble or attempt to repair batteries or chargers. No internal serviceable parts. Take batteries/chargers that have been damaged, broken, or need repair to a MILWAUKEE service facility to ensure the safety of the product is maintained.
Battery chemicals cause serious burns. Never allow contact with skin, eyes, or mouth. If a damaged battery 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.
Do not short circuit. A short-circuited battery pack may cause fire, personal injury, and product damage. 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 (e.g., coins, keys, nails, or small metal objects in a pocket, toolbox, or drawer).
Do not allow fluids to flow into battery pack. Corrosive or conductive fluids, such as seawater, certain industrial chemicals, and bleach or bleach-containing products, etc., can cause a short circuit. Do not use battery packs that have been exposed to these types of fluids.
Battery packs marked as Resistant are suitable for environments where incidental contact or exposure to oils, greases, and solvents can occur. These packs are not resistant to acids or other corrosive chemicals. Never immerse or allow fluids to penetrate the battery pack.
Store the battery pack and charger in a cool, dry place. Do not store where temperatures may exceed 120°F (50°C) such as in direct sunlight, a vehicle, or metal building during the summer.
Always ship Li-Ion batteries in accordance with the current regulations governing the chosen mode of transport (e.g. ground, air, sea). When in doubt, contact MILWAUKEE, the carrier or other trained Dangerous Goods professional to determine applicable regulations.
Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a replacement.

SYMBOLOGY

BATTERY OPERATION

Compared to NiCd battery pack types, MILWAUKEE Li-Ion battery packs deliver fade-free power for their entire run time. The tool will not experience a slow, gradual loss of power during use.

Transport
The regulations pertaining to the transport of Li-ion batteries are affected by whether the battery is transported in a personal vehicle or offered for shipment via a commercial carrier. Always ship Li-Ion batteries in accordance with the current regulations governing the chosen mode of transport (e.g. ground, air, sea). When in doubt, contact MILWAUKEE, the carrier or other trained Dangerous Goods professional to determine applicable regulations.
The personal transport of Li-Ion battery packs is allowed when done in accordance with these warnings and instructions. When shipping Li-ion batteries with a commercial carrier, they are shipped under classification UN 3480 (battery only) or UN 3481 (batteries contained in or packed with equipment). The proper packaging, labeling, marking, and documentation requirements are generally dependent upon whether the particular batteries are rated greater than or less than 100 Wh. Often, Li-Ion batteries rated 100 Wh or less are “excepted” from certain shipping regulations. In the U.S., products shipped via ground transport may be “excepted” from certain hazardous material shipping regulations if they are under 300Wh.
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.
Disposing of MILWAUKEE Li-Ion
Battery Packs
MILWAUKEE Li-Ion battery packs are more environmentally friendly than some other types of battery packs (e.g., nickel-cadmium). Always dispose of battery packs according to federal, state and local regulations. Contact a local recycling agency for recycling locations.
Even discharged battery packs 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.
RBRC Battery Recycling Seals
The RBRC™ Battery Recycling Seals (see the Symbology section) on battery packs indicate that MILWAUKEE has arranged for recycling with the Re-chargeable Battery Recycling Corporation (RBRC). At the end of its useful life, return the battery pack to a MILWAUKEE Branch Office/Service Center or a participating retailer. For more information, visit the RBRC website at www.rbrc.org.

CHARGER OPERATION

WARNING
Charge only MILWAUKEE M12™Li-Ion batteries in this MILWAUKEE Li-Ion charger. Other types of batteries may cause personal injury and damage.

When to Charge the Battery Pack with this MILWAUKEE Charger

Remove the battery pack from the product for charging when convenient for you and your job. MILWAUKEE batteries do not develop a “memory” when charged after only a partial discharge. It is not necessary to run down the battery pack before placing it on the charger.

Use the fuel gauge to determine when to charge your MILWAUKEE Li-Ion battery pack.
The battery pack’s charge can be “Topped-Off” before starting a big job or a long day of use.
The only time it is necessary to charge the MILWAUKEE Li-Ion battery pack is when the battery pack has reached the end of its charge. To signal the end of the charge, power to the product will drop quickly, allowing enough power to finish the operation. Charge the battery pack as needed.

How to Charge the Battery Pack

Align the battery pack with the bay and slide the battery pack into the charger as far as possible. The red light will come on, either flashing quickly (battery pack or charger is too hot or cold), flashing slowly (communication between pack and charger) or continuously (the pack is charging).

Charge time depends on the capacity of the battery pack. Heavily cycled batteries may take longer to charge completely.
After charging is complete, the continuous green light will come on.
The next pack inserted in the charger will begin charging when the previous pack is fully charged. To skip a pack and move on to the next, press the skip button.
If the light indicator flashes red and green or does not come on, check that the battery pack is fully seated in the bay. Remove the battery pack and reinsert. If the problem persists, remove the pack(s) and unplug the charger for at least 2 minutes. After 2 minutes, plug the charger back in and insert the pack. If the problem continues, contact a MILWAUKEE service facility.

Charging a Hot or Cold Battery Pack

The charger has advanced electronics that adjust the charge rate based on battery temperature. Hot or cold batteries may take longer to charge. When the battery pack temperature is outside the normal charging range, the red light will flash and the battery will not charge. Once the battery pack is within the acceptable range, normal charging will take place and the red light will be continuous. This optimizes charge time and battery life.

Battery Pack Temperature| Red Charger Indicator Light| Charging Status
---|---|---
Too Hot| Fast Flashing| Not charging
Normal Range| Continuous| Normal charging
Too Cold| Fast Flashing| Not charging

Powering the Charger with an Inverter or Generator

The charger will operate with most generators and inverters rated at 300 Watts or higher.

MAINTENANCE

WARNING
To reduce the risk of fire, personal

injury, and product damage due to a short circuit, never immerse a 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.
Always unplug the charger and remove the battery from the charger before performing any maintenance. Never disassemble the battery or charger. Contact a MILWAUKEE service facility for ALL repairs.
Do not expose battery packs, chargers or tools to fluids, water, or rain, or allow them to get wet. This could damage the tool, charger, and/or battery pack. Clean out dust and debris from tool, charger and bat-tery vents and electrical contacts by vacuuming or brushing. Clean housings with a damp, soapy cloth, keeping away from all electrical contacts. Certain cleaners and solvents, such as gasoline, turpentine, lacquer thinner, paint thinner, bleach, chlorinated cleaning solvents, ammonia and household deter-gents containing ammonia, are harmful to plastics and other insulated parts; plastic casings will become brittle and crack. Never use flammable or combus-tible solvents around batteries, charger, or tools.
Storage
As a general practice, it is best to unplug chargers and remove battery packs when not in use, however, no damage to the battery pack will occur. Store at room temperature away from moisture. Store bat-teries upright. Do not store in damp locations where corrosion of terminals may occur. Storing in high temperatures (over 120°F) for long periods can result in permanent capacity loss for any battery. Charge before use after storing for long periods.
Repairs
No serviceable parts.
