ENGLISH
The vibration and/or noise emission level given in this
information sheet has been measured in accordance with
a standardised test given in EN60745 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 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.
WARNING: To reduce the risk of injury, read the
instructionmanual.

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.

ENGLISH
Additional Specific Safety Rules for Sanders
WARNING: Contact with or inhalation of dusts arising
from sanding applications may endanger the health of
the operator and possible bystanders. Wear a dust mask
specifically designed for protection against toxic dust and
fumes and ensure that persons within or entering the work
area are alsoprotected.
WARNING: Use this tool in a well-ventilated area when
sanding ferrous metals. Do not operate the tool near
flammable liquids, gases or dust. Sparks or hot particles
from sanding or arcing motor brushes may ignite
combustiblematerials.
Additional Safety Instructions for Sanding
Operations
a ) Do not use excessively oversized sanding disc
paper. Follow manufacturer’s recommendations,
when selecting sanding paper. Larger sanding paper
extending beyond the sanding pad presents a laceration
hazard and may cause snagging, tearing of the disc
orkickback.
FURTHER SAFETY INSTRUCTIONS FOR ALL
OPERATIONS
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged rotating
wheel, backing pad, brush or any other accessory. Pinching or
snagging causes rapid stalling of the rotating accessory which
in turn causes the uncontrolled power tool to be forced in the
direction opposite of the accessory’s rotation at the point of
thebinding.
For example, if an abrasive wheel is snagged or pinched by the
workpiece, the edge of the wheel that is entering into the pinch
point can dig into the surface of the material causing the wheel
to climb out or kick out. The wheel may either jump toward or
away from the operator, depending on direction of the wheel’s
movement at the point of pinching. Abrasive wheels may also
break under theseconditions.
Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below:
a ) Maintain a firm grip on the power tool and position
your body and arm to allow you to resist kickback
forces. Always use auxiliary handle, if provided, for
maximum control over kickback or torque reaction
during start up. The operator can control torque reaction
or kickback forces, if proper precautions aretaken.
b ) Never place your hand near the rotating accessory.
Accessory may kickback over yourhand.
c ) Do not position your body in the area where power
tool will move if kickback occurs. Kickback will propel
the tool in direction opposite to the wheel’s movement at
the point ofsnagging.
d ) Use special care when working corners, sharp edges
etc. Avoid bouncing and snagging the accessory.
Corners, sharp edges or bouncing have a tendency to
snag the rotating accessory and cause loss of control
orkickback.
e ) Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent kickback
and loss ofcontrol.
run out of balance, vibrate excessively and may cause loss
ofcontrol.
g ) Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheel for
chips and cracks, backing pad for cracks, tear or
excess wear, wire brush for loose or cracked wires.
If power tool or accessory is dropped, inspect for
damage or install an undamaged accessory. After
inspecting and installing an accessory, position
yourself and bystanders away from the plane of
the rotating accessory and run the power tool at
maximum no-load speed for one minute. Damaged
accessories will normally break apart during this testtime.
h ) Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of
stopping small abrasive or workpiece fragments.
The eye protection must be capable of stopping flying
debris generated by various operations. The dust mask or
respirator must be capable of filtrating particles generated
by your operation. Prolonged exposure to high intensity
noise may cause hearingloss.
i ) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment. Fragments of
workpiece or of a broken accessory may fly away and
cause injury beyond immediate area ofoperation.
j ) Position the cord clear of the spinning accessory. If
you lose control, the cord may be cut or snagged and your
hand or arm may be pulled into the spinningaccessory.
k ) Never lay the power tool down until the accessory
has come to a complete stop. The spinning accessory
may grab the surface and pull the power tool out of
yourcontrol.
l ) Do not run the power tool while carrying it at your
side. Accidental contact with the spinning accessory
could snag your clothing, pulling the accessory into
yourbody.
m ) Regularly clean the power tool’s air vents. The
motor’s fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause
electricalhazards.
n ) Do not operate the power tool near flammable
materials. Sparks could ignite thesematerials.
o ) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution orshock.

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
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

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.
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
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

Sanding Drywall (Fig. I)
WARNING: To reduce the risk of personal injury, ALWAYS
wear a respirator approved for “Dust andMist”.
The drywall sander has an articulating sanding head. The head
can swivel in multiple directions, allowing the abrasive pad to
conform to the work surface. This action enables you to sand
the top, middle, and bottom of a wall or ceiling joint without
changingposition.
1. Turn the vacuum cleaner switch ON (I).
2. Turn drywall sander switchON.
3. Position the Drywall Sander lightly against the work surface.
Apply just enough pressure to align the sanding head with
the worksurface.
4. Apply additional pressure to engage the abrasive pad on the
work surface. Move the sander in an overlapping pattern to
smooth the drywall compound down to a“featheredge”.
5. Apply ONLY enough pressure to keep the abrasive pad flat
against the work.
6. Keep the sander in constant motion while the abrasive pad is in
contact with the work surface. Use a steady, sweeping motion.
Excessive pressure, stopping the sander on the work, or moving
the sander erratically can cause unacceptable swirl marks and
unevenness in the worksurface.
NOTE: Do not allow rotating abrasive pad to contact sharp
protrusions. Contact with protruding objects (nails, screws,
electrical boxes, etc.), can severely damage the abrasivepad.
Proper hand position requires one hand on the main handle5

installing attachments or accessories. An accidental
start-up can causeinjury.
Precautions to Take When Sanding Paint
Sanding of lead based paint is NOT RECOMMENDED due to the
difficulty of controlling the contaminated dust. The greatest
danger of lead poisoning is to children and pregnantwomen.
Since it is difficult to identify whether or not a paint contains
lead without a chemical analysis, we recommend the following
precautions when sanding any paint:
1. PERSONAL SAFETY
-No children or pregnant women should enter the work
area where the paint sanding is being done until all
clean up iscompleted.
-A dust mask or respirator should be worn by all persons
entering the work area. The filter should be replaced
daily or whenever the wearer has difficulty breathing.
See your local hardware store for the proper NIOSH-
approved dustmask.
