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.

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 residual current device (RCD)

protected supply. Use of an RCD 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 energising 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

jewellery. Keep your hair, clothing and gloves away

from moving parts. Loose clothes, jewellery 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 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 could 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

ENGLISH

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.

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.

• Hold tool by insulated gripping surfaces when

performing an operation where the pin may contact

hidden wiring. Contact with a “live” wire will make exposed

metal parts of the tool “live” and shock theoperator.

• 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.

• Always use trigger lock-off when tool is not in

immediate use. Using the trigger lock-off will prevent

accidentaldischarge.

• 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Maintenance.

• 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 lose control. When

tool is not in use, it should be locked in a safe place, out of the

reach ofchildren.

• 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 or any material too hard for

the pin to penetrate. Do not use the body of the tool

or top cap as a hammer. Discharged pin may follow

unexpected path and causeinjury.

• Always keep fingers clear of contact trip to prevent

injury from inadvertent release of thepin.

• 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.

• Fasteners must be driven straight into the material. Do not tilt

the nailer while driving fasteners. Personal injury can result

from ricocheted or jammedpins.

• Keep hands and body parts clear of immediate

workarea.



WARNING: To avoid injury keep hands and body away

from the front discharge area of thetool.

• Do not use tool in the presence of flammable dust, gases

or fumes. This tool produces sparks that can ignite gases or

dust causing an explosion. Driving a pin into another pin 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.

• Be aware of material thickness when using nailer. A

protruding pin may causeinjury.

• Do not drive pins blindly into walls, floors or other work

areas. Fasteners driven into live electrical wires, plumbing, or

other types of obstructions can result ininjury.

• 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.

Residual Risks

In spite of the application of the relevant safety regulations

and the implementation of safety devices, certain residual risks

cannot be avoided. These are:

• Impairment ofhearing.

• Risk of personal injury due to flyingparticles.

Refer to the indicators below for the charge status of the battery

pack.

Charge Indicators

Charging

Fully Charged

Hot/Cold Pack Delay*

* 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 by refusing to light or by

displaying problem pack or charger blink pattern.

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 authorised service centre.

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

XR 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

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 25.4mm long

with a screw head diameter of 7–9mm, screwed into wood to

an optimal depth leaving approximately 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. Never let any liquid get inside the tool;

never immerse any part of the tool into a liquid.

lithium-ion battery packs are burned.

• If battery contents come into contact with the skin,

immediately wash area with mild soap and water. If

battery liquid gets into the eye, rinse water over the open 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 persists, seek medical

attention.



WARNING: Burn hazard. Battery liquid may be flammable

if exposed to spark or flame.



WARNING: Never attempt to open the battery pack for

any reason. If battery pack case is cracked or damaged,

ENGLISH

do not insert into charger. Do not crush, drop or damage

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 (i.e., pierced with a nail, hit with

a hammer, stepped on). Electric shock or electrocution

may result. Damaged battery packs should be returned to

service centre for recycling.



WARNING: Fire hazard. Do not store or carry 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, etc.



CAUTION: When not in use, place tool on its side on

a stable surface where it will not cause a tripping

or falling hazard. Some tools with large battery packs

will stand upright on the battery pack but may be easily

knocked over.

Transportation



WARNING: Fire hazard. Transporting batteries can

possibly cause fire if the battery terminals inadvertently

come in contact with conductive materials. When

transporting batteries, make sure that the battery

terminals are protected and well insulated from materials

that could contact them and cause a short circuit.

DeWALT

batteries comply with all applicable shipping

regulations as prescribed by industry and legal standards which

include UN Recommendations on the Transport of Dangerous

Goods; International Air Transport Association (IATA) Dangerous

Goods Regulations, International Maritime Dangerous Goods

(IMDG) Regulations, and the European Agreement Concerning

The International Carriage of Dangerous Goods by Road (ADR).

Lithium-ion cells and batteries have been tested to section 38.3

of the UN Recommendations on the Transport of Dangerous

Goods Manual of Tests and Criteria.

In most instances, shipping a

DeWALT

battery pack will be

excepted from being classified as a fully regulated Class 9

Hazardous Material. In general, only shipments containing a

lithium-ion battery with an energy rating greater than 100 Watt

Hours (Wh) will require being shipped as fully regulated Class 9.

All lithium-ion batteries have the Watt Hour rating marked on

the pack. Furthermore, due to regulation complexities,

DeWALT

does not recommend air shipping lithium-ion battery packs

alone regardless of Watt Hour rating. Shipments of tools with

batteries (combo kits) can be air shipped as excepted if the Watt

Hour rating of the battery pack is no greater than 100 Whr.

Regardless of whether a shipment is considered excepted

or fully regulated, it is the shipper's responsibility to consult

the latest regulations for packaging, labeling/marking and

documentation requirements.

The information provided in this section of the manual is

provided in good faith and believed to be accurate at the time

the document was created. However, no warranty, expressed or

implied, is given. It is the buyer’s responsibility to ensure that its

activities comply with the applicable regulations.

Transporting the FLEXVOLT

Battery

The

DeWALT

FLEXVOLT

battery has two modes: Use and

Transport.

Use Mode: When the FLEXVOLT

battery stands alone or is in

DeWALT

18V product, it will operate as an 18V battery. When

the FLEXVOLT

battery is in a 54V or a 108V (two 54V batteries)

product, it will operate as a 54V battery.

Transport Mode: When the cap is attached to the FLEXVOLT

battery, the battery is in Transport mode. Keep the cap for

shipping.

When in Transport mode, strings

of cells are electrically

disconnected within the pack

resulting in 3 batteries with a

lower Watt hour (Wh) rating as compared to 1 battery with a

higher Watt hour rating. This increased quantity of 3 batteries

with the lower Watt hour rating can exempt the pack from

certain shipping regulations that are imposed upon the higher

Watt hour batteries.

For example, the Transport

Wh rating might indicate

3x36 Wh, meaning 3

batteries of 36 Wh each.

The Use Wh rating might

indicate 108Wh (1battery implied).

Storage Recommendations

1. The best storage place is one that is cool and dry away

from direct sunlight and excess heat or cold. For optimum

battery performance and life, store battery packs at room

temperature when not in use.

2. For long storage, it is recommended to store a fully charged

battery pack in a cool, dry place out of the charger for

optimal results.

NOTE: Battery packs should not be stored completely depleted

of charge. The battery pack will need to be recharged before

use.

Labels on Charger and Battery Pack

In addition to the pictographs used in this manual, the labels

on the charger and the battery pack may show the following

pictographs:

Read instruction manual before use.
