Make sure that the 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
•
necessary. Use of improper extension cord could result in
risk of fire, electric shock or electrocution.
When operating a charger outdoors, always provide
•
a dry location and use an extension cord suitable
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 heavier the cord and
thus the greater its capacity. An undersized cord will
cause a drop in line voltage resulting in loss of power and
overheating. The following table shows the correct size
to use depending on total length of all extension cords
plugged together, and nameplate ampere rating. If in
doubt, use the next heavier gauge.

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.
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.
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 and
ventilation slots.
Always unplug the charger from the power supply
•
when there is no battery pack in the cavity.

Charging a Battery (Fig. C)
1. Plug the charger into an appropriate outlet.
2. Insert and fully seat battery pack. The red charging
light(s) will continuously blink while charging.
3. Charging is complete when the red charging light(s)
remain(s) continuously ON. Battery pack can be left in
charger or removed. Some chargers require the battery
pack release button to be pressed for removal.

WARNING: Only charge batteries in air temperature
over 40 ° F (4.5 ° C) and below 104 ° F (+40 ° C).
4. Charger will not charge a faulty battery pack, which may
be indicated by the charging light(s) staying OFF. Take
charger and battery pack to an authorized service center
if light(s) stay(s) OFF.
NOTE: Refer to label near charging light(s) on charger
for blink patterns. Older chargers may have additional
information and/or may not have a yellow indicator light.
NOTE: To remove the battery pack, some chargers
require the battery pack release button to be pressed.
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 pack has reached an
appropriate temperature. The charger then automatically
switches to the pack charging mode. This feature ensures
14
maximum battery pack life.
12
A cold battery pack may charge at a slower rate than a warm
12
battery pack.
The hot/cold pack delay will be indicated by the red light(s)
continuing to blink but with the yellow light continuously
ON. Once the battery pack has reached an appropriate
temperature, the yellow light will turn OFF and the charger
will resume the charging procedure.
DCB118 and DCB1112 Chargers
The DCB118 and DCB1112 chargers are equipped with
an internal fan designed to cool the battery pack. The fan
will turn on automatically when the battery pack needs to
be cooled.
Never operate the charger if the fan does not operate
properly or if ventilation slots are blocked. Do not permit
foreign objects to enter the interior of the charger.
Electronic Protection System
Li-Ion tools are designed with an Electronic Protection
System that will protect the battery pack against overloading,
overheating or deep discharge. The tool will automatically
turn off and the battery pack will need to be recharged.
Important Charging Notes
1. Longest life and best performance can be obtained if
the battery pack is charged when the air temperature
is between 65 °F – 75 °F (18 ° C– 24 °C). DO NOT charge
when the battery pack is below +40 °F (+4.5 °C), or
above +104 °F (+40 °C). This is important and will
prevent serious damage to the battery pack.
2. The charger and battery pack may become warm to the
touch while charging. This is a normal condition, and
does not indicate a problem. To facilitate the cooling of
