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 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

g ) Follow all charging instructions and do not charge

the battery pack or tool outside the temperature

range specified in the instructions. Charging

improperly or at temperatures outside the specified range

may damage the battery and increase the risk offire.

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.

b ) Never service damaged battery packs. Service

of battery packs should only be performed by the

manufacturer or authorized serviceproviders.

Impact Wrench Safety Warnings -

All Operations

• Hold the power tool by insulated gripping surfaces,

when performing an operation where the fastener may

contact hidden wiring. Fasteners contacting a "live" wire

may make exposed metal parts of the power tool "live" and

could give the operator an electricshock.

• Wear ear protectors during use. Exposure to noise can

cause hearingloss.

WARNING: Impact wrenches are not torque

wrenches. DO NOT use this tool for tightening

fasteners to specified torques. An independent,

calibrated torque measurement device such as a torque

wrench should be used when under tightened or over

tightened fasteners can lead to the failure of thejoint.

Chargers

DeWALT chargers require no adjustment and are designed to be

as easy as possible tooperate.

Electrical Safety

The electric motor has been designed for one voltage only.

Always check that the battery pack voltage corresponds to the

voltage on the rating plate. Also make sure that the voltage of

your charger corresponds to that of yourmains.

iYour DeWALT charger is double insulated in

accordance with IEC60335; therefore no earth wire

isrequired.

If the supply cord is damaged, it must be replaced only by

DeWALT or an authorised serviceorganisation.

Using an Extension Cable

An extension cord should not be used unless absolutely

necessary. Use an approved extension cable suitable for

the power input of your charger (see Technical Data). The

minimum conductor size is 1mm2; the maximum length

is30m.

When using a cable reel, always unwind the cablecompletely.

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 remove the battery pack, if detachable, 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 and accessories. 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.

h ) Keep handles and grasping surfaces dry, clean and

free from oil and grease. Slippery handles and grasping

surfaces do not allow for safe handling and control of the

tool in unexpectedsituations.

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.

e ) Do not use a battery pack or tool that is damaged or

modified. Damaged or modified batteries may exhibit

unpredictable behaviour resulting in fire, explosion or risk

ofinjury.

f ) Do not expose a battery pack or tool to fire or

excessive temperature. Exposure to fire or temperature

above 130°C may causeexplosion.

Charging a Battery (Fig.B)

1. Plug the charger into an appropriate outlet before inserting

batterypack.

2. Insert the battery pack 5 into the charger, making sure the

battery pack is fully seated in the charger. The red (charging)

light will blink repeatedly 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 4 on the batterypack.

NOTE: To ensure maximum performance and life of lithium‑ion

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.

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

ENGLISH

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

metal buildings insummer).

• Do not incinerate the battery pack even if it is severely

damaged or is completely worn out. The battery pack can

explode in a fire. Toxic fumes and materials are created when

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,

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. NOTE: Lithium‑ion batteries should not be put in

checkedbaggage.

DeWALT batteries comply with all applicable shipping

regulations as prescribed by industry and legal standards which

include UN Recommendations on the Transport of Dangerous

ENGLISH

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Wh.

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 FLEXVOLTTM Battery

The DeWALT FLEXVOLTTM battery has two modes: Use

andTransport.

Use Mode: When the FLEXVOLTTM battery stands alone or is

in a DeWALT 18V (20V Max) product, it will operate as an 18V

(20V Max) battery. When the FLEXVOLTTM battery is in a 54V

(60V Max) or a 108V (120V Max) (two 54V (60V Max) batteries)

product, it will operate as a 54V (60V Max)battery.

Transport Mode: When the cap is attached to the FLEXVOLTTM

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).

Example of Use and Transport Label Marking

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:

increase the speed of fastening applications in wood using lag

bolts, lag screws and structural wood screws.

Scaffolding Mode (Fig. C)

DCF921

Your tool is equipped with a mode designed for scaffolding

applications. In forwards rotation it will run down the nut on

the scaffold clamp and then impact for a period of time before

cutting off to avoid over tightening of the fastener. In reverse

rotation it will impact to break the nut free, before winding

down the nut and cutting off after a period of time to limit

damage to clamps.

NOTE: Always check scaffolding clamps are tightened correctly

with a torque wrench.

Precision Wrench™ Mode(Fig. C)

In addition to low speed impacting modes, this tool features

the Precision Wrench™ mode which grants the user greater

control in both fastening and loosening applications. When set

in forward, the tool will fasten at 2500 RPM until impact begins.

The tool will then pause for 0.5 seconds before continuing

to impact at a rate of 3550 IPM, providing the user with

greater control and reducing the chance of overtightening or

damagingmaterial.

When set in reverse, the tool will impact at a normal speed and

rate of 3550 IPM. Upon sensing that the fastener has broken

free, the tool will cease to impact and will reduce speed to help

prevent “run‑off” of loose hardware.

DeWALT

电池符合所有适用的行业和法律标准规定的运输规范，包

括《联合国危险品运输建议规章范本》(UN Recommendations on the

Transport of Dangerous Goods)、《国际航空运输协会 (IATA) 危险品规则》

(International Air Transport Association(IATA) Dangerous Goods Regulations) 、

《国际海运危险品(IMDG) 规则》(International Maritime Dangerous Goods

(IMDG)Regulations) 和《欧洲危险货物国际公路运输协定》(European

Agreement Concerning The International Carriage of Dangerous Goods by

Road) (ADR)。锂离子电池和电池包已遵循《联合国危险品运输建议

规章范本手册》第 38.3 节关于测试和标准的说明通过测试。

大多数情况下，发运

DeWALT

电池包不属于完全管制的 9 类危险品。

通常情况下，只有当运输包含一个能量等级大于 100 瓦时(Wh) 的锂

离子电池时，才需要作为完全管制的 9 类危险品发运。所有锂离子

电池外壳上均标注有瓦时等级。此外，由于法规比较复杂，无论瓦

时等级是多少，

DeWALT

都不建议单独空运锂离子电池包。发运包含

电池的工作（组合套件）时，如果电池包的能量等级不大于 100 瓦时

(Wh)，则可以按计划空运。

无论发运是否纳入完全管制范围内，运输公司均有责任遵循最新法

规中关于包装、标签/标记和单据的要求。本手册本节的信息是出于

善意提供，且认为在编制文档时准确无误。但是不提供明示或暗示

的担保。购买方负有确保其行为遵守适用法规的责任。

运输 FLEXVOLTTM 电池

DeWALT

FLEXVOLTTM 电池有两种模式：使用和运输。

使用模式：当 FLEXVOLTTM 电池单独使用或用于

DeWALT

18 伏(最大

20 伏) 产品时，将作为功率为 18 伏（最大 20 伏）的电池进行操作。

当 FLEXVOLTTM 电池用于 54 伏（最大 60 伏）或 108 伏(最大 120 伏)（两

简体中文

个

伏（最大

伏）电池）的产品时，将作为

伏（最大

伏）的电

池进行操作。

运输模式：当电池盖连接到 FLEXVOLTTM 电

池时，电池会进入运输模式。保留电池盖

用于运输。

处于运输模式时，电池包内部的电池芯会处于断电状态，使 3 个低

瓦时 (Wh) 等级的电池相当于 1个高瓦时等级电池。这样，增加 3个

低瓦时等级的电池可以使电池包不必遵守适用于更高瓦时电池的

运输法规。

例如，若运输额定瓦时为3

x 36 瓦时，则表示 3 个36 瓦

时的电池。使用瓦时额定

值可能是 108 瓦时(表示 1

个电池)。

存放建议

1. 最好将电池存放在阴凉、干燥、远离阳光直射、不会过热或过冷

的地方。为了获得最佳的电池性能和使用寿命，请您在不使用电

池包时将其存储在室温下。

2. 长期存储时，建议将完全充电的电池包从充电器取出，存储在阴

凉、干燥的地方，以达到最佳效果。

注：电池包不应在电池已完全耗尽的状态下存放。使用电池包之前，

必须重新为电池包充电。
