GENERAL POWER TOOL SAFETY WARNINGS
WARNING! Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or
seriousinjury.
SAVE ALL WARNINGS AND
INSTRUCTIONS FOR FUTURE
REFERENCE
The term “power tool” in the warnings refers to your mains-
operated (corded) power tool or battery-operated (cordless)
powertool.
1) Work Area Safety
a ) Keep work area clean and well lit. Cluttered or dark
areas inviteaccidents.
b ) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools
create sparks which may ignite the dust orfumes.
c ) Keep children and bystanders away while
operating a power tool. Distractions can cause you
to losecontrol.
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 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.
4) Power Tool Use and Care
a ) Do not force the power tool. Use the correct
power tool for your application. The correct power
tool will do the job better and safer at the rate for
which it wasdesigned.
b ) Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must
berepaired.
c ) Disconnect the plug from the power source and/
or the battery pack from the power tool before
making any adjustments, changing accessories,
or storing power tools. Such preventive safety
measures reduce the risk of starting the power
toolaccidentally.
d ) Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the
power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands
of untrainedusers.
e ) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and
any other condition that may affect the power
tool’s operation. If damaged, have the power
tool repaired before use. Many accidents are
caused by poorly maintained powertools.
f ) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier tocontrol.
g ) Use the power tool, accessories and tool bits, etc.
in accordance with these instructions, taking
ENGLISH
3
into account the working conditions and the
work to be performed. Use of the power tool for
operations different from those intended could result
in a hazardoussituation.
5) Battery Tool Use and Care
a ) Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of fire when used
with another batterypack.
b ) Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury andfire.
c ) When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws, or other small metal objects,
that can make a connection from one terminal to
another. Shorting the battery terminals together may
cause burns or afire.
d ) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
orburns.
6) Service
a ) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool ismaintained.
Nailer Safety Warnings
Always assume that the tool contains fasteners.
Careless handling of the nailer can result in unexpected
firing of fasteners and personalinjury.
Do not point the tool towards yourself or anyone
nearby. Unexpected triggering will discharge a fastener
causing aninjury.
Do not actuate the tool unless the tool is placed
firmly against the workpiece. If the tool is not in
contact with the workpiece, the fastener may be deflected
away from yourtarget.
Disconnect the tool from the power source when the
fastener jams in the tool. While removing a jammed
fastener, the nailer may be accidentally activated if it is
pluggedin.
Do not use this nailer for fastening electrical cables.
It is not designed for electric cable installation and may
damage the insulation of electric cables thereby causing
electric shock or firehazards.
Additional Nailer Safety Warnings
WARNING: When using any nailer, all safety
precautions, as outlined below, should be followed
to avoid the risk of death or serious injury. Read and
understand all instructions before operating thetool.
WARNING: NEVER spray or in any other way apply
lubricants or cleaning solvents inside the tool. This can
seriously affect the life and performance of thetool.
WARNING: If the tool has been dropped or you
suspect tool damage perform tool operation check as
defined in the mode selection section of the manual. If
it doesn’t perform according to the manual, stop using
the tool and have it serviced at an authorized
DeWALT
servicecenter.
Keep hands and body parts away from the discharge
area of the tool. While in use NEVER grasp the tool by the
magazine or canister, a mis-driven nail can exit the nose
causing injury.
Hold tool by insulated gripping surfaces when
performing an operation where the fastener may
contact hidden wiring. Contact with a “live” wire will
make exposed metal parts of the tool “live” and shock
theoperator.
Actuating tool may result in flying debris, collation
material, or dust which could harm operator’s
eyes. Operator and others in work area MUST wear
safety glasses with side shields. These safety glasses
must conform to ANSI Z87.1 requirements (approved
glasses have “Z87” printed or stamped on them. It is
the employer’s responsibility to enforce the use of eye
protection equipment by the tool operator and other
people in the workarea.
Always wear appropriate personal hearing and
other protection during use. Under some conditions
and duration of use, noise from this product may
contribute to hearingloss.
Disconnect battery pack from the tool when not in
use. Always remove battery pack and remove fasteners
from magazine before leaving the area or passing the
tool to another operator. Do not carry tool to another
work area in which changing location involves the use
of scaffoldings, stairs, ladders, and the like, with battery
pack connected. Do not make adjustments, perform
maintenance or clear jammed fasteners while battery is
inplace.
Do not remove, tamper with, or otherwise cause the
tool, trigger or trigger lock-off, to become inoperable.
Do not tape or tie trigger in the on position. Do not remove
spring from contact trip. Make daily inspections for free
movement of trigger. Uncontrolled discharge couldresult.
Inspect tool before use. Do not operate a tool if any
portion of the tool, trigger, or trigger lock-off is
inoperable, disconnected, altered, or not working
properly. Damaged parts or missing parts should be
repaired or replaced before use. Refer toRepairs.
Do not alter or modify the tool in anyway.
Always assume that the tool containsfasteners.
Do not point the tool at co-workers or yourself at
any time. No horseplay! Work safe! Respect the tool as a
workingimplement.
Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to
ENGLISH
4
lose control. When tool is not in use, it should be locked in
a safe place, out of the reach ofchildren.
Always use trigger lock-off when tool is not in
immediate use. Using the trigger lock-off will prevent
accidentaldischarge.
Do not overreach. Maintain proper footing and balance
at all times. Loss of balance may cause personalinjury.
Use the tool only for its intended use. Do not
discharge fasteners into open air, concrete, stone,
extremely hard woods, knots or any material
too hard for the fastener to penetrate. Do not
use the body of the tool or top cap as a hammer.
Discharged fastener may follow unexpected path
and causeinjury.
Always keep fingers clear of contact trip to prevent
injury from inadvertent release of thepusher.
Refer to the Maintenance and Repairs sections for
detailed information on the proper maintenance of
thetool.
Always operate the tool in a clean, lighted area.
Be sure the work surface is clear of any debris and be
careful not to lose footing when working in elevated
environments such asrooftops.
Do not drive fastener near edge of material. The
workpiece may split causing the nail to ricochet, injuring
you or a co-worker. Be aware that the fastener may follow
the grain of the wood (shiner), causing it to protrude
unexpectedly from the side of the work material. Drive the
chisel point of the fastener perpendicular to the grain to
reduce risk ofinjury.
Do not drive nails onto the heads of other fasteners
or with the tool at too steep an angle. Personal injury
from strong recoil jammed nails, or ricocheted nails
mayresult.
Keep hands and body parts clear of immediate work
area. Hold workpiece with clamps when necessary to
keep hands and body out of potential harm. Be sure the
workpiece is properly secured before pressing the nailer
against the material. The contact trip may cause the work
material to shiftunexpectedly.
Do not use tool in the presence of flammable dust,
gases or fumes. The tool may produce a spark that could
ignite gases causing a fire. Driving a nail into another nail
may also cause aspark.
Keep face and body parts away from back of the tool
cap when working in restricted areas. Sudden recoil
can result in impact to the body, especially when nailing
into hard or densematerial.
Grip tool firmly to maintain control while allowing
tool to recoil away from work surface as fastener
is driven. In Bump mode if contact trip is allowed to
recontact work surface before trigger is released an
unwanted fastener will befired.
Choice of triggering method is important. Check the
manual for triggeringoptions.
Always select an actuation system that is
appropriate to the fastener application and the
training of theoperator.
Use caution when handling, loading or unloading
fasteners. Fasteners have sharp points which could
causeinjury.
Only wear gloves that provide adequate feel and
safe control of the trigger and any adjustingdevices.
Bump/Sequential Selector Switch
Sequential Action
When using the tool in sequential action, do not
actuate the tool unless the tool is placed firmly
against theworkpiece.
Bump Action
When using the tool in bump action, be careful of
unin tentional double fires resulting from tool recoil.
Unwanted fasteners may be driven if the contact trip is
allowed to accidentally re-contact the worksurface.
To Avoid Double Fires:
ʵ Do not engage the tool against the work surface with
a strongforce.
ʵ Allow the tool to recoil fully after eachactuation.
ʵ Use sequential actionmode.
When bump actuating the framing nailer, always
keep tool in control. Inaccurate placement of tool can
result in misdirected discharge of anail.
Be aware of material thickness when using nailer. A
protruding nail may causeinjury.
Depth adjustment: To reduce risk of serious injury
from accidental actuation when attempting to
adjust depth, ALWAYS;
ʵ Remove batterypack.
ʵ Engage trigger lock-off.
ʵ Avoid contact with trigger during adjustments
Do not drive nails blindly into walls, floors or other
work areas. Fasteners driven into live electrical wires,
plumbing, or other types of obstructions can result in
injury and or propertydamage.
Stay alert, watch what you are doing and use
common sense when operating a power tool. Do not
use tool while tired or under the influence of drugs,
alcohol, or medication. A moment of inattention
while operating power tools may result in serious
personalinjury.

from short circuits. So 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.
Shipping the
DeWALT
FLEXVOLT™ Battery
The D
e
WALT FLEXVOLT™ battery has two modes: Use and
Shipping.
Use Mode: When the FLEXVOLT™ battery stands alone or is
in a D
e
WALT 20V Max* product, it will operate as a 20V Max*
battery. When the FLEXVOLT™ battery is in a 60V Max* or a
120V Max* (two 60V Max* batteries) product, it will operate
as a 60V Max* battery.
Shipping Mode: When
the cap is attached to the
FLEXVOLT™ battery, the
battery is in Shipping Mode.
Strings of cells are electrically
disconnected within the pack resulting in three batteries
with a lower Watt hour (Wh) rating as compared to one
battery with a higher Watt hour rating. This increased
quantity of three batteries with the lower Watt hour rating
can exempt the pack from certain shipping regulations that
are imposed upon the higher Watt hourbatteries.
The battery label indicates two Watt hour ratings (see
example). Depending on how the battery is shipped, the
appropriate Watt hour rating must be used to determine
the applicable shipping requirements. If utilizing the
shipping cap, the pack will be considered 3 batteries at
the Watt hour rating indicated for “Shipping”. If shipping
without the cap or in a tool, the pack will be considered one
battery at the Watt hour rating indicated next to “Use”.
USE: 120 Wh Shipping: 3 x 40 Wh
Example of Use and Shipping Label Marking
For example, Shipping Wh rating might indicate 3 x 40 Wh,
meaning 3 batteries of 40 Watt hours each. The Use Wh
rating might indicate 120 Wh (1 batteryimplied).
Fuel Gauge Battery Packs (Fig. B)
Some
DeWALT
battery packs include a fuel gauge which
consists of three green LED lights that indicate the level of
charge remaining in the batterypack.
The fuel gauge is an indication of approximate levels of
charge remaining in the battery pack according to the
followingindicators:
75–100% charged
51–74% charged
< 50% charged
Pack needs to be charged
To actuate the fuel gauge, press and hold the fuel gauge
button. A combination of the three green LED lights will
illuminate designating the level of charge left. When the
level of charge in the battery is below the usable limit, the
fuel gauge will not illuminate and the battery will need to
berecharged.
Fig. B
NOTE: The fuel gauge is only an indication of the charge left
on the battery pack. It does not indicate tool functionality
and is subject to variation based on product components,
temperature and end-userapplication.

Important Safety Instructions for All
Battery Chargers
WARNING: Read all safety warnings and all
instructions for the battery pack, charger and
power tool. 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 the ones in this manual.
The charger and battery pack are specifically designed to
worktogether.
These chargers are not intended for any uses other
than charging
DeWALT
rechargeable batteries.
Any other uses may result in risk of fire, electric shock
orelectrocution.
Do not expose the charger to rain orsnow.
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 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.

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

2. Insert the battery pack
12
into the charger, making sure
the battery pack is fully seated in the charger. The red
(charging) light will blink continuously indicating that
the charging process hasstarted.
3. The completion of charge will be indicated by the red
light remaining ON continuously. The battery pack is
fully charged and may be used at this time or left in the
charger. To remove the battery pack from the charger,
push the battery release button
25
on the batterypack.
NOTE: To ensure maximum performance and life of lithium-
ion battery packs, charge the battery pack fully before

Charger Operation
Refer to the indicators below for the charge status of the
batterypack.
DCB107, DCB112, DCB113, DCB115, DCB118, DCB132
Charging
Fully Charged
Hot/Cold Pack Delay**
** DCB107, DCB112, DCB113, DCB115, DCB118,
DCB132: 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.
The compatible charger(s) will not charge a faulty battery
pack. The charger will indicate faulty battery pack by
refusing tolight.
NOTE: This could also mean a problem with acharger.
If the charger indicates a problem, take the charger and
battery pack to be tested at an authorized servicecenter.
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 will charge at a slower rate than a warm
battery pack. The battery pack will charge at that slower rate
throughout the entire charging cycle and will not return to
maximum charge rate even if the battery packwarms.
The DCB118 charger is 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 if the Electronic
Protection System engages. If this occurs, place the lithium-
ion battery pack on the charger until it is fullycharged.
Wall Mounting
DCB107, DCB112, DCB113, DCB115, DCB118, DCB132
These chargers are designed to be wall mountable or to
sit upright on a table or work surface. If wall mounting,
locate the charger within reach of an electrical outlet,
and away from a corner or other obstructions which may
impede air flow. Use the back of the charger as a template
for the location of the mounting screws on the wall. Mount
the charger securely using drywall screws (purchased
separately) at least 1" (25.4 mm) long, with a screw head
diameter of 0.28–0.35" (7–9mm), screwed into wood to an
optimal depth leaving approximately 7/32" (5.5 mm) of the
screw exposed. Align the slots on the back of the charger
with the exposed screws and fully engage them in theslots.
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.
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 and 75°F (18° 24°C). DO NOT charge
the battery pack 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

where the surrounding air temperature is
approximately 65°F – 75°F (18° – 24°C);
d. If charging problems persist, take the tool, battery
pack and charger to your local servicecenter.
4. The battery pack should be recharged when it fails to
produce sufficient power on jobs which were easily
done previously. DO NOT CONTINUE to use under these
conditions. Follow the charging procedure. You may
also charge a partially used pack whenever you desire
with no adverse effect on the batterypack.
5. 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 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.
6. Do not freeze or immerse the charger in water or any
otherliquid.
