The vibration and/or noise emission level given in this information
sheet has been measured in accordance with a standardised test
given in EN62841 and may be used to compare one tool with
another. It may be used for a preliminary assessment of exposure.

WARNING: The declared vibration and/or noise emission
level represents the main applications of the tool. However,
if the tool is used for different applications, with different
accessories or is poorly maintained, the vibration and/or
noise emission may differ. This may significantly increase the
exposure level over the total working period.
An estimation of the level of exposure to vibration and/or
noise should also take into account the times when the tool is
switched off or when it is running but not actually doing the
job. This may significantly reduce the exposure level over the
total working period.
Identify additional safety measures to protect the operator
from the effects of vibration and/or noise such as: maintain
the tool and the accessories, keep the hands warm (relevant
for vibration), organisation of work patterns.

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

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 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 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 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 and clothing 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.
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 a second.

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 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.
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 authorised service providers.

Impact Wrench/Driver 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.

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.

• Risk of burns due to accessories becoming hot
  during operation.

• Risk of personal injury due to prolonged use.

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 EN60335; therefore, no earth wire
is required.
If the supply cord is damaged, it must be replaced only by
DeWALT or an authorised service organisation.

Mains Plug Replacement

(U.K. & Ireland Only)
If a new mains plug needs to be fitted:

• Safely dispose of the old plug.

• Connect the brown lead to the live terminal in the plug.
• Connect the blue lead to the neutral terminal. WARNING: No connection is to be made to the
earth terminal.

Follow the fitting instructions supplied with good quality plugs.
Recommended fuse: 3 A.

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.

CAUTION: Children should be supervised to ensure that
they do not play with the appliance.
NOTICE: Under certain conditions, with the charger
plugged into the power supply, the exposed charging
contacts inside the charger can be shorted by foreign
material. Foreign materials of a conductive nature such as,
but not limited to, 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 charger
before attempting to clean.

• 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 charger to rain or snow.
• Pull by plug rather than cord when disconnecting
charger. This will reduce risk of damage to electric plug
and cord.
• Make sure that 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.
• Do not place any object on top of charger or place
the charger on a soft surface that might block the
ventilation slots and result in excessive internal heat.

Charging a Battery (Fig. B)

NOTE: To ensure maximum performance and life of lithium‑ion
battery packs, charge the battery pack fully before first use.
1. Plug the charger into an appropriate outlet before inserting
battery pack.
2. Insert the battery pack 6 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 Stage 1 charging blink indicator represents the charge
process that charges the majority of the battery’s capacity.
Stage 2 charging blink indicator represents the remainder, or
top off charge process, for the battery to reach full capacity.
4. The completion of charge for Stage 1 or Stage 2 will be
indicated by the stage’s light remaining ON continuously.
The battery pack is fully charged when both Stage 1 and
Stage 2 charging lights remain ON continuously, and it may
be removed and used at this time or left in the charger.
NOTE: To remove the battery pack, some chargers require the
battery pack release button 5 to be pressed.
Refer to the indicators below for the charge status of the
battery pack.

Indicators

• 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
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

Battery Packs

Important Safety Instructions for All
Battery Packs

When ordering replacement battery packs, be sure to include
catalogue number and voltage.
The battery pack is not fully charged out of the carton. Before
using the battery pack and charger, read the safety instructions
below. Then follow charging procedures outlined.

READ ALL INSTRUCTIONS

• Do not charge or use battery in explosive atmospheres,
such as in the presence of flammable liquids, gases or
dust. Inserting or removing the battery from the charger may
ignite the dust or fumes.
• Never force battery pack into charger. Do not modify

• DO NOT splash or immerse in water or other liquids.
• Do not store or use the tool and battery pack in locations
where the temperature may fall below 4 ˚C (39.2 ˚F)
(such as outside sheds or metal buildings in winter), or
reach or exceed 40 ˚C (104 ˚F) (such as outside sheds or
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 persist, 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 into 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
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 Wh rating marked on the pack.
Furthermore, due to regulation complexities, DeWALT does
not recommend air shipping lithium‑ion battery packs alone
regardless of Wh rating. Shipments of tools with batteries (combo
kits) can be air shipped as excepted if the Wh 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 FLEXVOLT® battery has two modes: Use
and Transport.
Use Mode: When the FLEXVOLTTM battery stands alone or is in
a DeWALT 18V product, it will operate as an 18V battery. When
the FLEXVOLTTM 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 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).

Storage Recommendations

1. The best storage place is one that is cool and dry away from
direct sunlight and excessive 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:

L Read instruction manual before use.

Instructions for Use

WARNING: Always observe the safety instructions and
applicable regulations. WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start‑up can cause injury.

Proper Hand Position (Fig. A, C)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown. WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
sudden reaction.
Proper hand position requires one hand on the main handle 8 .

Variable Speed Trigger Switch (Fig. A)

To turn the tool on, squeeze the trigger switch 1 . To turn the
tool off, release the trigger switch. Your tool is equipped with
a brake. The anvil will stop when the trigger switch is fully
released. The variable speed switch enables you to select the
best speed for a particular application. The more you squeeze
the trigger, the faster the tool will operate. For maximum tool
life, use variable speed only for starting holes or fasteners.
NOTE: Continuous use in variable speed range is not
recommended. It may damage the switch and should
be avoided.

Forward/Reverse Control Button (Fig. A)

A forward/reverse control button 2 determines the direction of
the tool and also serves as a lock‑off button.
To select forward rotation, release the trigger switch 1 and
depress the forward/ reverse control button on the right side of the tool.
To select reverse, release the trigger switch and depress the
forward/reverse control button on the left side of the tool.
The centre position of the control button locks the tool in the off
position. When changing the position of the control button, be
sure the trigger is released.
NOTE: The first time the tool is run after changing the direction
of rotation, you may hear a click on start-up. This is normal and
does not indicate a problem.

Worklights (Fig. A)
There are three worklights 7 located around the 6.35 mm hex
chuck 4 . The worklights are activated when the trigger switch
is depressed.
When the trigger is released, the worklight will stay illuminated
for up to 20 seconds.
NOTE: The worklights are for lighting the immediate work
surface and are not intended to be used as a flashlight.

Mode Selector (Fig. D)
Your tool is equipped with a mode selector 11 which allows
you to select one of three modes. Select the mode based on the
application and control the speed of the tool using the variable
speed trigger switch 1 .

Precision Drive (Fig. A)
In addition to normal impacting modes, this tool features the
Precision Drive mode which enables greater control in lighter
applications to avoid damage to materials or fasteners. It is ideal
for light applications such as cabinet hinge screws or machine
screws. Precision Drive mode will work as a screwdriver in light

applications, before hesitating as the screw head reaches the
workpiece, and then (if required) start a slow controlled impact
to ensure the head ends perfectly flush.
NOTE: This mode is for light duty screwdriving applications. If
the tool will not drive a fastener in Precision Mode, please select
mode 2 which will give the additional power required.

Mode 1 Precision Drive rpm 0–1000
Mode 2 Normal Impacting rpm 0–2800
Mode 3 High Speed Impacting rpm 0–3250

Quick‑Release Chuck (Fig. A, E, F)

WARNING: Use only impact accessories. Non-impact
accessories may break and cause a hazardous condition.
Inspect accessory prior to use to ensure that it contains
no cracks.
NOTE: The chuck accepts 6.35 mm hex accessories only.

front of the tool. Remove the accessory (Fig. F).

Usage (Fig. A)

Your impact tool generates the following maximum torque:
Cat # Nm
DCF85M 205

CAUTION: Ensure fastener and/or system will withstand
the level of torque generated by the tool. Excessive torque
may cause breakage and possible personal injury.
1. Place the accessory on the fastener head. Keep the tool
pointed straight at the fastener.
2. Press variable speed trigger switch 1 to start operation.
Release variable speed trigger switch to stop operation.
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 fastening torque.
– Accessory size: Failure to use the correct accessory size
will cause a reduction in fastening torque.
– Bolt size: Larger bolt diameters generally require
higher fastening torque. Fastening torque will also vary
according to length, grade, and torque coefficient.
– Bolt: Ensure that all threads are free of rust and other
debris to allow proper fastening torque.
– Material: The type of material and surface finish of the
material will affect fastening torque.
– Fastening time: Longer fastening time results in
increased fastening torque. Using a longer fastening
time than recommended could cause the fasteners to
be overstressed, stripped or damaged.
