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
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.

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
battery pack in any way to fit into a non‑compatible
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.
• Do not operate charger if it has received a sharp blow,
been dropped, or otherwise damaged in any way. Take it
to an authorised servicecentre.
• Do not disassemble charger; take it to an authorised service
centre when service or repair is required. Incorrect reassembly
may result in a risk of electric shock, electrocution orfire.
• In case of damaged power supply cord, the supply cord must
be replaced immediately by the manufacturer, its service agent
or similar qualified person to prevent anyhazard.
• 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 two chargerstogether.
• The charger is designed to operate on standard
230V household electrical power. Do not attempt to
use it on any other voltage. This does not apply to the
vehicularcharger.

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 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 excess heat or cold. For optimum
Example of Use and Transport Label Marking
charger as battery pack may rupture causing serious
personalinjury.
• Charge the battery packs only in DeWALT chargers.
• 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 persists, seek
medicalattention.

Lubrication
Your power tool requires no additionallubrication.
MAINTENANCE
Your power tool has been designed to operate over a long
period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and
regularcleaning.
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

The charger and battery pack are notserviceable.
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.
Usage (Fig. A)
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.
Proper Hand Position (Fig. E)
WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position asshown.
