Charging A Battery; Important Charging Notes - DeWalt DW074LR Instruction Manual

ENGLISH
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

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 maximum battery
pack life.
A cold battery pack may charge at a slower rate than a warm
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 the
battery pack after use, avoid placing the charger or battery
pack in a warm environment such as in a metal shed or an
uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check operation of receptacle by plugging in a lamp or
other appliance;
b. Check to see if receptacle is connected to a light switch
which turns power off when you turn out
the lights;
c. If charging problems persist, take the tool, battery pack
and charger to your local service center.
4. You may charge a partially used pack whenever you desire
with no adverse effect on the battery pack.
Charger Cleaning Instructions

WARNING: Shock hazard. Disconnect the charger from
the AC outlet before cleaning. Dirt and grease may be
removed from the exterior of the charger using a cloth
or soft non‑metallic brush. Do not use water or any
cleaning solutions.
User Safety
Personal Safety
Stay alert, watch what you are doing, and use common
•
sense when operating a laser product. Do not use the
tool while tired or under the influence of drugs, alcohol,
or medication. A moment of inattention while operating
laser products may result in serious personal injury.
Use personal protective equipment. Always wear ANSI
•
Z87.1 eye protection (CAN/CSA Z94.3). Depending on the
work conditions, wearing protective equipment such as a dust
mask, non‑skid safety shoes, hard hat and hearing protection
will reduce personal injury.
