DeWalt DWC709 Instruction Manual page 36

• 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 2 chargers together.
• The charger is designed to operate on standard
household electrical power (120 Volts). Do not attempt
to use it on any other voltage. This does not apply to the
vehicular charger.

Chargers
Your tool uses a D WALT Charger. Be sure to read all safety
E
instructions before using your charger.
Charging Procedure (Fig. 1)
DANGER: Electrocution hazard. 120V and 220V present at
charging terminals. Do not probe with conductive objects. Danger of
electric shock or electrocution.
1. Plug the charger into an appropriate outlet
before inserting battery pack.
2. Insert the battery pack into the 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.
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.
Indicator Light Operation
Charge Indicators
Some chargers are designed to detect certain problems that can
FIG. 1
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.
