ENGLISH
2) Electrical Safety
a ) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will
reduce risk of electricshock.
b ) Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed orgrounded.
c ) Do not expose power tools to rain or wet
conditions. Water entering a power tool will increase
the risk of electricshock.
d ) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase
the risk of electricshock.
e ) When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electricshock.
f ) If operating a power tool in a damp location
is unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of a GFCI
reduces the risk of electricshock.
3) Personal Safety
a ) Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools
may result in serious personalinjury.
b ) Use personal protective equipment. Always wear
eye protection. Protective equipment such as a dust
mask, non‑skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personalinjuries.
c ) Prevent unintentional starting. Ensure the switch
is in the off position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energizing power tools that have the switch
on invitesaccidents.
d ) Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may result
in personalinjury.
e ) Do not overreach. Keep proper footing and
balance at all times. This enables better control of the
power tool in unexpectedsituations.
f ) Dress properly. Do not wear loose clothing or
jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long hair
can be caught in movingparts.
g ) If devices are provided for the connection of dust
extraction and collection facilities, ensure these
are connected and properly used. Use of dust
collection can reduce dust‑relatedhazards.
GENERAL POWER TOOL SAFETY WARNINGS
WARNING: Read all safety warnings, instructions,
illustrations and specifications provided with
this power tool. Failure to follow all instructions
listed below may result in electric shock, fire and/or
seriousinjury.
SAVE ALL WARNINGS AND INSTRUCTIONS

Important Safety Instructions for All
Battery Chargers
WARNING: Read all safety warnings, instructions,
and cautionary markings for the battery pack,
charger and product. Failure to follow the
warnings and instructions may result in electric
shock, fire and/or seriousinjury.
• DO NOT attempt to charge the battery pack with
any chargers other than a DeWALT charger. DeWALT
chargers and battery packs are specifically designed to
worktogether.
• These chargers are not intended for any uses other
than charging DeWALT rechargeable battery packs.
Charging other types of battery packs may cause them to
overheat and burst, resulting in personal injury, property
damage, fire, electric shock orelectrocution.
• Do not expose the charger to rain orsnow.
• Do not allow water or any liquid to entercharger.
• Pull by the plug rather than the cord when
disconnecting the charger. This will reduce the risk of
damage to the electric plug andcord.
• 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
The RBRC® Seal
Please take your spent battery packs to

batteries. The three batteries have the Watt hour rating
labeled“Shipping”on the battery pack. If shipping without
the cap or in a tool, the pack is one battery at the Watt hour
rating labeled"Use."
Example battery pack label:
USE: 120Wh SHIPPING: 3x 40Wh
In this example, the battery pack is three batteries with
40Watt hours each when using the cap. Otherwise, the
battery pack is one battery with 120Watthours.
Shipping the DeWALT FLEXVOLT™ Battery Pack
The DeWALT FLEXVOLT™ battery pack has a battery cap that
should be used when shipping the batterypack.
Attach the cap to the battery pack to ready it for shipping.
This converts the battery pack to three separate 20V
eye for 15minutes or until irritation ceases. If medical
attention is needed, the battery electrolyte is composed of a
mixture of liquid organic carbonates and lithiumsalts.
• Contents of opened battery cells may cause
respiratory irritation. Provide fresh air. If symptoms
persist, seek medicalattention.
• Battery liquid may be flammable if exposed to spark
orflame.
• Never attempt to open the battery pack for any
reason. If the battery pack case is cracked or
damaged, do not insert into the charger. Do not crush,
drop or damage the battery pack. Do not use a battery pack
or charger that has received a sharp blow, been dropped,
run over or damaged in any way (e.g., pierced with a nail,
hit with a hammer, stepped on). Damaged battery packs
should be returned to the service center forrecycling.
Storage Recommendations
The best storage place is one that is cool and dry, away
from direct sunlight and excess heat or cold. Store the fully
charged battery pack out of thecharger.
Battery Pack Cleaning Instructions
Dirt and grease may be removed from the exterior of the
battery pack using a cloth or soft non-metallic brush. Do not
use water or any cleaningsolutions.
Fuel Gauge Battery Packs (Fig.B)
Some battery packs include a fuel gauge. When the fuel
gauge button is pressed and held, the LED lights will
indicate the approximate level of charge remaining. This
does not indicate tool functionality and is subject to
variation based on product components, temperature, and
end-userapplication.
Transportation
WARNING: Fire hazard. Do not store, carry, or
transport the battery pack so that metal objects
can contact exposed battery terminals. For
example, do not place the battery pack in aprons,
pockets, tool boxes, product kit boxes, drawers, etc.,
with loose nails, screws, keys, coins, hand tools, etc.
When transporting individual battery packs, make
sure that the battery terminals are protected and well
insulated from materials that could contact them and
cause a short circuit. NOTE: Li‑ion battery packs should
not be put in checked baggage on airplanes and must
be properly protected from short circuits if they are in
carry‑onbaggage.

ENGLISH
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
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.
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 packs 26 are 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
