• Do not place any object on top of charger or place the charger on a soft surface
that might block the ventilation slots and result in excessive internal heat. Place
the charger in a position away from any heat source. The charger is ventilated through slots
in the top and the bottom of the housing.
• Do not operate charger with damaged cord or plug.
• Do not operate charger if it has received a sharp blow, been dropped, or otherwise
damaged in any way. Take it to an authorized service center.
• Do not disassemble charger; take it to an authorized service center when service or
repair is required. Incorrect reassembly may result in a risk of electric shock, electrocution
or fire.
• Disconnect the charger 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 two chargers together.
• The charger is designed to operate on standard 120 volt household electrical
power. Do not attempt to use it on any other voltage. This does not apply to the
vehicular charger.
Using Automatic Tune-Up™ Mode
The automatic Tune-Up™ Mode equalizes or balances the individual cells in the battery pack
allowing it to function at peak capacity. Battery packs should be tuned up weekly or after
10 charge/discharge cycles or whenever the pack no longer delivers the same amount of
work. To use the automatic Tune-Up™, place the battery pack in the charger and leave it for
at least 8 hours. The charger will cycle through the following modes.
1. The red light will blink continuously indicating that the 1-hour charge cycle has started.
2. When the 1-hour charge cycle is complete, the light will stay on continuously and will no
longer blink. This indicates that the pack is fully charged and can be used at this time.
3. If the pack is left in the charger after the initial 1-hour charge, the charger will begin the
Automatic Tune-Up™ mode. This mode continues up to 8 hours or until the individual
cells in the battery pack are equalized. The battery pack is ready for use and can be
removed at any time during the Automatic Tune-Up™ mode.
4. Once the Automatic Tune-Up™ mode is complete, the charger will begin a maintenance
charge; the red indicator will remain lit.
Chargers
Your tool uses a D WALT charger. Be sure to read all safety instructions before using your
E
charger. Consult the chart at the end of this manual for compatibility of chargers and battery
packs.
Charging Procedure (Fig. 2)
DANGER: Electrocution hazard. 120 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 2, making sure the pack is
fully seated in charger. 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 continuously. 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.
