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 cavities. Always unplug the charger from the power supply
when there is no battery pack in the cavity. Unplug charger before
attempting to clean.
•
DO NOT attempt to charge the battery pack with any
chargers other than the ones in this manual.
The charger
and battery pack are specifically designed to work together.
•
These chargers are not intended for any uses other than
charging D
E
WALT rechargeable batteries.
Any other uses
may result in risk of fire, electric shock or electrocution.
•
Do not expose charger to rain or snow.
•
Pull by plug rather than cord when disconnecting charger.
This will reduce risk of damage to electric plug and cord.
•
Make sure that cord is located so that it will not be stepped
on, tripped over, or otherwise subjected to damage or
stress.
•
Do not use an extension cord unless it is absolutely neces-
sary.
Use of improper extension cord could result in risk of fire,
electric shock, or electrocution.
•
An extension cord must have adequate wire size (AWG or
American Wire Gauge) for safety.
The smaller the gauge
number of the wire, the greater the capacity of the cable, that is
16 gauge has more capacity than 18 gauge. When using more
than one extension to make up the total length, be sure each
individual extension contains at least the minimum wire size.
•
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 charg-
er in a position away from any heat source. The charger is ven-
tilated through slots in the top and the bottom of the housing.
•
Do not operate charger with damaged cord or plug
— have
them replaced immediately.
•
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 serv-
ice 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 2 chargers together.
•
The charger is designed to operate on standard house-
hold electrical power (120 Volts). 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 individ-
ual cells in the battery pack allowing it to function at peak capacity.
Battery packs should be tuned up weekly or after 10 charge/dis-
charge 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 Tune-Up mode.
