Chargers
Your tool uses a DEWALT 12, 14.4, 18 Volt charger. Be sure to read all safety
instructions before using your charger. Consult the chart at the end of this manual for
compatibility of chargers and battery packs.
FIG. 1
Charging Procedure (Fig. 1)
DANGER: Electrocution Hazard. 240 volts are present at charging terminals. Do not
probe with conductive objects. Electric shock or electrocution may result.
1. Plug the charger into an appropriate outlet before inserting battery pack.
2. Insert the battery pack into the charger, as shown in Figure 1, making sure the
pack is fully seated. The red (charging) light will blink continuously indicating that
the charging process has started.
3. The completion of charge will be indicated by the red light remaining ON continu-
ously. The pack is fully charged and may be used at this time or left in the charger.
Indicator Light Operation
Charge Indicators
Some chargers are 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. If the problem persists, try a different battery
pack to determine if the charger 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 tested at an authorized service center.
HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when the charger 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 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
Some chargers have a Problem Power Line indicator. When the charger is used with
some portable power sources such as generators or sources that convert DC to AC, the
charger 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
The charger and battery pack can be left connected with the red light glowing
indefinitely. The charger will keep the battery pack fresh and fully charged.
NOTE: A battery pack will slowly lose its charge when kept out of the charger. 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 that is
not plugged into an appropriate AC source.
WEAK BATTERY PACKS: Chargers can also detect a weak battery pack. Such
batteries are still usable but should not be expected to perform as much work. The
charger will indicate to replace battery pack.
Important Charging Notes
1. Longest life and best performance can be obtained if the battery pack is charged
when the air temperature is between 18°- 24°C (65°F and 75°F). DO NOT charge
the battery pack in an air temperature below +4.5°C (+40°F), or above +40.5°C
(+105°F). This is important and will prevent serious damage to the battery pack.
