DeWalt DC021 Operating Instructions Manual page 11

Charging Procedure (Fig. 1, 4)
DANGER: Electrocution hazard.
230 volts are present at charging
terminals and outlets of the
DC022/DC021. 115 volts are
present at charging terminals of
the DC022LX. Do not probe with
conductive objects. Danger of
electric shock or electrocution.
WARNING: Pinch hazard. Do not
release the battery hold-down quickly.
Personal injury may result.
1. Plug the worklight/charger power cord (e) into
an appropriate AC power outlet or generator.
2. Lift the battery hold-down (g) with one hand
and insert the battery pack into the charging
receptacle. Slowly place the battery hold-down
on battery pack to hold battery pack firmly.
3. The red light on the top rear of the base 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.
5. Charge time for D WALT 7.2 –18 V battery
E
packs is approximately one hour.
Battery Cap (fi g. 5)
A protective battery cap is supplied to cover the
contacts of a detached battery pack. Without the
protective cap in place, loose metal objects could
short circuit the contacts, causing a fire hazard and
damaging the battery pack.
1. Take off the protective battery cap before
placing the battery pack in the charger
or tool (Fig. 5A).
2. Place the protective cap over the contacts
immediately after removing the battery pack
from the charger or tool (Fig. 5B).
WARNING: Make sure the protective
battery cap is in place before storing or
carrying a detached battery pack.
Automatic Refresh
The automatic refresh mode will equalize or balance
the individual cells in the battery pack at its peak
capacity. Battery packs should be refreshed
overnight after every 10th charge/discharge cycle
or whenever the pack no longer delivers the same
amount of work.
To refresh your battery pack, place it in the charger
as usual. The red light will blink continuously
indicating that the charge cycle has started.
When the 1-hour charge cycle (depending on
charger) has completed, the light will stay on
continuously and will no longer blink. The battery
pack is fully charged and can be used at this time.
If the battery pack is left in the charger after the initial
1-hour charge (depending on charger), the charger
will automatically initiate the refresh mode. This
mode will continue up to 8 hours, but the battery
pack can be removed at any time during the refresh
mode.
Hot/Cold Pack Delay
When the charger detects a battery pack that is
too hot or too cold, it automatically starts a Hot/
Cold Pack Delay, suspending charging until the
battery has reached an appropriate temperature.
The charger then automatically switches to the pack
charging mode. This feature ensures maximum
battery life. The red indicator blinks long, then short
while in the Hot/Cold Pack Delay mode.
OPERATION
NOTE: If using the worklight/charger on AC power,
the green LED indicator (l) must be illuminated. DO
NOT use worklight/charger if the LED indicator is
not illuminated.
1. Place the folded DC021/DC022 on a stable,
level surface so that the charger receptacles are
in sight.
2. With one hand securely holding the handle
(b), use the other hand to lift the worklight/
charger housing (j). The worklight housing can
be positioned in multiple directions on the top of
the H-frame support (m). The H-frame support
will pivot in 4 positions around the base of the
charger housing.
3. Position the worklight as desired. Press the ON/
OFF switch (a) to ON.
When finished using the worklight/charger, turn the
ON/OFF swith to OFF, fold the worklight/charger
housing down to the flat position for storage (Fig. 1).
Replacing the Fluorescent Bulb
(Fig. 6, 7)
WARNING: Shock Hazard.
Disconnect battery pack and unplug
tool before replacing the fluorescent
bulb. Such preventative safety
measures reduce the risk of personal
injury.
CAUTION: Vision may be impaired
when looking directly into fluorescent
light.
