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 seriousinjury.
SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTUREREFERENCE
The term “power tool” in the warnings refers to your
mains‑operated (corded) power tool or battery‑operated (cordless)
powertool.
1) Work Area Safety
a ) Keep work area clean and well lit. Cluttered or dark
areas inviteaccidents.
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 orfumes.
c ) Keep children and bystanders away while operating
a power tool. Distractions can cause you to losecontrol.
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
electricshock.
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 orgrounded.
c ) Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electricshock.
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
electricshock.
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 electricshock.
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
electricshock.
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 personalinjury.
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 personalinjuries.
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
invitesaccidents.
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
personalinjury.
e ) Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power tool
in unexpectedsituations.
f ) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair and clothing away from
moving parts. Loose clothes, jewellery or long hair can be
caught in movingparts.
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‑relatedhazards.
h ) Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause severe
injury within a fraction of asecond.
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
wasdesigned.
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 berepaired.
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 toolaccidentally.
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 untrainedusers.
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 powertools.
f ) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are less
likely to bind and are easier tocontrol.
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 hazardoussituation.
5
ENGLISH
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 unexpectedsituations.
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 batterypack.
b ) Use power tools only with specifically designated
battery packs. Use of any other battery packs may create
a risk of injury andfire.
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 afire.
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 orburns.
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
ofinjury.
f ) Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or temperature
above 130°C may causeexplosion.
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 offire.
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 ismaintained.
b ) Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized serviceproviders.
Impact Wrench Safety Warnings -

Transporting the FLEXVOLTTM Battery
The DeWALT FLEXVOLTTM battery has two modes: Use
andTransport.
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
forshipping.
When in Transport mode, strings
of cells are electrically
disconnected within the pack
resulting in 3batteries with a
lower Watt hour (Wh) rating as compared to 1battery with a
higher Watt hour rating. This increased quantity of 3batteries
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
3x36Wh, meaning
3batteries of 36Wh each.
The Use Wh rating might
indicate 108Wh (1batteryimplied).
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 inuse.
2. For long storage, it is recommended to store a fully charged
battery pack in a cool, dry place out of the charger for
optimalresults.
NOTE: Battery packs should not be stored completely
depleted of charge. The battery pack will need to be recharged
beforeuse.
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
followingpictographs:

Mode Selector (Fig.A, C)
Your tool is equipped with a mode selector7 which allows you
to select one of three speeds or Precision Wrench™ mode. Select
the mode based on the maximum speed/torque needed and
control the speed of the tool using the variable speed trigger
switch1.
Precision Wrench™ (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 2000 RPM until impact begins.
The tool will then pause for 0.5 seconds before continuing
to impact at a rate of 3250 IPM, providing the user with
greater control and reducing the chance of overtightening or
damagingmaterial.
When set in reverse, the tool will impact at a normal speed and
rate of 3250 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.

Always check torque with a torque wrench, as the fastening
torque is affected by many factors including the following:
‑Voltage: Low voltage, due to a nearly discharged
battery, will reduce fasteningtorque.
‑Accessory size: Failure to use the correct accessory size
will cause a reduction in fasteningtorque.
‑Bolt size: Larger bolt diameters generally require
higher fastening torque. Fastening torque will also vary
according to length, grade, and torquecoefficient.
‑Bolt: Ensure that all threads are free of rust and other
debris to allow proper fasteningtorque.
‑Material: The type of material and surface finish of the
material will affect fasteningtorque.
‑Fastening time: Longer fasten ing time results in
increased fastening torque. Using a longer fastening
time than recommended could cause the fasteners to
be overstressed, stripped ordamaged.

《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
个 54 伏（最大 60 伏）电池）的产品时，将作为54 伏（最大 60 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。
