Charging A Battery - DeWalt DCF961 Instruction Manual

for outdoor use. Use of a cord suitable for outdoor use
reduces the risk of electric shock.
•
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. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating. When
using more than one extension to make up the total length,
be sure each individual extension contains at least the
minimum wire size. The following table shows the correct
size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge. The
lower the gauge number, the heavier the cord.

WARNING: If the plug or power cord is damaged,
it must be replaced by the manufacturer or its
representative or by an equally qualified person to
avoid danger.
•
Do not place any object on top of the 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 the charger with a damaged cord
or plug–have them replaced immediately.
•
Do not operate the 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 the 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 2 chargers together.
•
The charger is designed to operate on standard
120V household electrical power. Do not attempt to
use it on any other voltage. This does not apply to the
vehicular charger.

WARNING: Shock hazard. Do not allow any liquid to
get inside the charger. Electric shock may result.

WARNING: Burn hazard. Do not submerge the battery
pack in any liquid or allow any liquid to enter the
battery pack. Never attempt to open the battery pack
for any reason. If the plastic housing of the battery pack
breaks or cracks, return to a service center for recycling.

CAUTION: Burn hazard. To reduce the risk of injury,
charge only D
types of batteries may overheat and burst resulting in
personal injury and property damage.

CAUTION: Under certain conditions, with the charger
plugged into the power supply, the charger can be
shorted by foreign material. Foreign materials of a
conductive nature, such as, but not limited to, grinding
dust, metal chips, steel wool, aluminum foil or any
buildup of metallic particles should be kept away from
the charger cavities. Always unplug the charger from
the power supply when there is no battery pack in the
cavity. Unplug the charger before attempting to clean.

CHARGING A BATTERY

nOTE: To ensure maximum performance and life of lithium‑
ion battery packs, charge the battery pack fully before first use.
14
1. Plug the charger into an appropriate outlet before
12
inserting battery pack.
12
2. Connect the charger and battery pack, making sure
the battery is fully seated. The (charging) light will blink
continuously indicating that the charging process
has started.
3. The Stage 1 Charging blink indicator represents the
charge process that charges the majority of the battery's
capacity. Stage 2 Charging blink indicator represents the
remainder, or top off charge process, for the battery to
reach full capacity.
4. The completion of charge for Stage 1 or Stage 2 will be
indicated by the Stage's light remaining ON continuously.
The battery pack is fully charged when both Stage 1 and
Stage 2 charging lights remain ON continuously, and it may
be removed and used at this time or left in the charger.
nOTE: To remove the battery pack, some chargers require
the battery pack release button to be pressed.
Indicators
* The red light will continue to blink, but a yellow indicator
light will be illuminated during this operation. Once the
battery pack has reached an appropriate temperature, the
yellow light will turn off and the charger will resume the
charging procedure.
