• Disconnect the charger/radio from the outlet before attempting any cleaning. This will
reduce the risk of electric shock. Removing the battery pack will not reduce this risk.
• NEVER attempt to connect 2 charger/radios together.
• This charger/radio is designed to operate on 120 Volts, 60 Hz AC. It also operates on
EWALT battery packs. Do not use any other voltage.
SAVE THESE INSTRUCTIONS
The DC012 will charge 7.2–18 Volt DEWALT battery packs and will play using 12–18 Volt
EWALT battery packs. Your battery may also be charged in DEWALT 1-hour chargers, 15-minute
chargers or vehicular 12-volt charger. Be sure to read all safety instructions before using your
charger. Consult the chart in this manual for compatibility of chargers and battery packs.
Charging Procedure (Fig. 1)
DANGER: Electrocution hazard. 120 volts present at charging terminals. Do not probe with
conductive objects. Danger of electric shock or electrocution. Keep battery door closed and
latched at all times
1. Plug the charger/radio into an appropriate AC power outlet or generator.
2. Insert the battery pack into the charging receptacle (I). Make sure the pack is fully seated in
the charger/radio, close the rear door and fasten the latch (H).
3. The red light on the front of the radio (J) will blink continuously indicating that the charging
process has started.
4. The completion of charge will be indicated by the red light remaining ON continuously.
Indicator Light Operation
The charger/radio is designed to detect certain problems that can arise with battery packs.
Problems are indicated by the red light flashing at a fast rate. If this occurs, re-insert battery
pack into the charger/radio. If the problem persists, try a different battery pack to determine if
the charger/radio is OK. If the new pack charges correctly, then the original pack is defective and
should be returned to a service center or other collection site for recycling. If the new battery pack
elicits the same trouble indication as the original, have the charger/radio tested at an authorized
HOT/COLD PACK DELAY
The charger/radio has a Hot/Cold Pack Delay feature: when the charger/radio detects a battery
that is hot, it automatically starts a Hot Pack Delay, suspending charging until the battery has
cooled. After the battery has cooled, the charger/radio automatically switches to the Pack
Charging mode. This feature ensures maximum battery life. The red light flashes long, then short
while in the Hot Pack Delay mode.
PROBLEM POWER LINE
The charger/radio has a Problem Power Line indicator. When the charger/radio is used with some
portable power sources such as generators or sources that convert DC to AC, the charger/radio
may temporarily suspend operation, flashing the red light with two fast blinks followed by a
pause. This indicates the power source is out of limits.
LEAVING THE BATTERY PACK IN THE CHARGER/RADIO
The charger/radio and battery pack can be left connected with the red light glowing indefinitely.
The charger/radio will keep the battery pack fresh and fully charged.
NOTE: A battery pack will slowly lose its charge when kept out of the charger/radio. If the battery
pack has not been kept on maintenance charge, it may need to be recharged before use. A
battery pack may also slowly lose its charge if left in a charger/radio that is not plugged into an
appropriate AC source.
WEAK BATTERY PACKS: The charger/radio can also detect a weak battery. Such batteries
are still usable but should not be expected to perform as much work. In such cases, about 10
seconds after battery insertion, the charger/radio will beep rapidly 8 times to indicate a weak
battery condition. The charger/radio will then go on to charge the battery to the highest capacity
Important Charging Notes
1. Longest life and best performance can be obtained if the battery pack is charged when the
air temperature is between 65°F and 75°F (18°- 24°C). DO NOT charge the battery pack in
an air temperature below +40°F (+4.5°C), or above +105°F (+40.5°C). This is important and
will prevent serious damage to the battery pack.
2. The charger/radio and battery pack may become warm to touch while charging. This is a
normal condition, and does not indicate a problem. To facilitate the cooling of the battery pack
after use, avoid placing the charger/radio or battery pack in a warm environment such as in
a metal shed, or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check current at receptacle by plugging in a lamp or other appliance.
b. Check to see if receptacle is connected to a light switch which turns power off when you
turn out the lights.
c. Move the charger/radio and battery pack to a location where the surrounding air
temperature is approximately 65°– 75°F (18°–24°C).
d. If charging problems persist, take the tool, battery pack and charger/radio to your local
4. The battery pack should be recharged when it fails to produce sufficient power on jobs which
were easily done previously. DO NOT CONTINUE to use under these conditions. Follow the
charging procedure. You may also charge a partially used pack whenever you desire with no
adverse affect on the battery pack.
5. Under certain conditions, with the charger/radio plugged into the power supply, the exposed
charging contacts inside the charger can be shorted by foreign material. Foreign materials
of a conductive nature such as, but not limited to, steel wool, aluminum foil, or any buildup
of metallic particles should be kept away from charger/radio cavities. Always keep the
battery door closed when there is no battery pack in the cavity. Unplug charger/radio before
attempting to clean.
6. Do not freeze or immerse the charger/radio in water or any other liquid.
WARNING: Shock hazard. Don’t allow any liquid to get inside the charger/radio. Electric
shock may result.
CAUTION: Never attempt to open the battery pack for any reason. If the plastic housing of
the battery pack breaks or cracks, return to a service center for recycling.
