GENERAL POWER TOOL SAFETY WARNINGS
WARNING! Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions 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 ground fault circuit
interrupter (GFCI) protected supply. Use of a GFCI
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 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 energizing 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
jewelry. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewelry 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 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. 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

3
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 behavior 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 authorized serviceproviders.
Additional Safety Instructions for Sanders

chemicalsare:
•lead from lead-based paints,
•crystalline silica from bricks and cement and other
masonry products, and
•arsenic and chromium from chemically-
treatedlumber.
Your risk from these exposures varies, depending on how
often you do this type of work. To reduce your exposure to
these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are
specially designed to filter out microscopicparticles.
•Avoid prolonged contact with dust from power
sanding, sawing, grinding, drilling, and other
construction activities. Wear protective clothing and
wash exposed areas with soap and water. Allowing
dust to get into your mouth, eyes, or lay on the skin may
promote absorption of harmfulchemicals.
WARNING: Use of this tool can generate and/
or disperse dust, which may cause serious and
permanent respiratory or other injury. Always use
NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles
away from face andbody.

The D
e
WALT FLEXVOLT™ battery has two modes: Use and
Shipping.
Use Mode: When the FLEXVOLT™ battery stands alone or is
in a D
e
WALT 20V Max* product, it will operate as a 20V Max*
battery. When the FLEXVOLT™ battery is in a 60V Max* or a
120V Max* (two 60V Max* batteries) product, it will operate
as a 60V Max* battery.

5
Shipping Mode: When the
cap is attached to the
FLEXVOLT™ battery, the
battery is in Shipping Mode.
Strings of cells are
electrically disconnected within the pack resulting in three
batteries with a lower Watt hour (Wh) rating as compared to
one battery with a higher Watt hour rating. This increased
quantity of three batteries with the lower Watt hour rating
can exempt the pack from certain shipping regulations that
are imposed upon the higher Watt hourbatteries.
The battery label indicates two Watt hour ratings (see
example). Depending on how the battery is shipped, the
appropriate Watt hour rating must be used to determine
the applicable shipping requirements. If utilizing the
shipping cap, the pack will be considered 3 batteries at
the Watt hour rating indicated for “Shipping”. If shipping
without the cap or in a tool, the pack will be considered one
battery at the Watt hour rating indicated next to “Use”.
USE: 120 Wh Shipping: 3 x 40 Wh
Example of Use and Shipping Label Marking
For example, Shipping Wh rating might indicate 3 x 40 Wh,
meaning 3 batteries of 40 Watt hours each. The Use Wh
rating might indicate 120 Wh (1 batteryimplied).
Fuel Gauge Battery Packs (Fig. B)
Some
DeWALT
battery packs include a fuel gauge which
consists of three green LED lights that indicate the level of
charge remaining in the batterypack.
The fuel gauge is an indication of approximate levels of
charge remaining in the battery pack according to the
followingindicators:
75–100% charged
51–74% charged
< 50% charged
Pack needs to be charged
To actuate the fuel gauge, press and hold the fuel gauge
button. A combination of the three green LED lights will
illuminate designating the level of charge left. When the

Important Safety Instructions for All
Battery Chargers
WARNING: Read all safety warnings and all
instructions for the battery pack, charger and
power tool. Failure to follow the warnings and
instructions may result in electric shock, fire and/
or seriousinjury.
•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 the charger to rain orsnow.
•Pull by the plug rather than the cord when
disconnecting the charger. This will reduce the risk of
damage to the electric plug andcord.
•Make sure that the 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.
•When operating a charger outdoors, always provide
a dry location and use an extension cord suitable
for outdoor use. Use of a cord suitable for outdoor use
reduces the risk of electricshock.
•An extension cord must have adequate wire size
(AWG or American Wire Gauge) for safety. The smaller
the gauge number of the wire, the greater the capacity
of the cable, that is, 16 gauge has more capacity than 18

6
gauge. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. When using
more than one extension to make up the total length,
be sure each individual extension contains at least the
minimum wire size. The following table shows the correct
size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge. The
lower the gauge number, the heavier thecord.

*DCB107, DCB112, DCB113, DCB115, DCB118, DCB132:
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 pack by
refusing tolight.

7
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 authorized servicecenter.
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
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
DCB107, DCB112, DCB113, DCB115, DCB118, DCB132
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 1" (25.4 mm) long, with a screw head
diameter of 0.28–0.35" (7–9mm), screwed into wood to an
optimal depth leaving approximately 7/32" (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.
Important Charging Notes
1. Longest life and best performance can be obtained if
the battery pack is charged when the air temperature is
between 65°F and 75°F (18°– 24°C). DO NOT charge
the battery pack below +40°F (+4.5°C), or above
+104°F (+40°C). This is important and will prevent
serious damage to the batterypack.
2. The charger and battery pack may become warm to the
touch while charging. This is a normal condition, and
does not indicate a problem. To facilitate the cooling of
the battery pack after use, avoid placing the charger or
battery pack in a warm environment such as in a metal
shed or an uninsulatedtrailer.
3. If the battery pack does not charge properly:
a. Check operation of receptacle by plugging in a lamp
or other appliance;
b. Check to see if receptacle is connected to a light
switch which turns power off when you turn out the
lights;
c. Move the charger and battery pack to a location
where the surrounding air temperature is
approximately 65°F– 75°F (18°– 24°C);
d. If charging problems persist, take the tool, battery
pack and charger to your local servicecenter.
4. The battery pack should be recharged when it fails to
produce sufficient power on jobs which were easily
done previously. DO NOT CONTINUE to use under these
conditions. Follow the charging procedure. You may
also charge a partially used pack whenever you desire
with no adverse effect on the batterypack.
5. Foreign materials of a conductive nature such as, but
not limited to, grinding dust, metal chips, 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 the charger
before attempting toclean.
6. Do not freeze or immerse the charger in water or any
otherliquid.
Storage Recommendations
1. The best storage place is one that is cool and dry, away
from direct sunlight and excess heat orcold.
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.

ASSEMBLY AND ADJUSTMENTS
WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start-up can causeinjury.
Attaching Sanding Discs (Fig. D)
Your sander is designed to use 5" (127 mm) sanding discs 9
with an 8-hole dust extraction pattern. Sanding discs for the
DCW210 attach with hook andloop.
The recommended DWE64233 sanding discs are available
at extra cost from your local dealer or authorized
DeWALT
servicecenter.
To Attach Sanding Disc to the Sanding
Pad (Fig. D)
1. Turn the sander over so that the sanding pad 6 is
facingupward.
2. Clean the dust from the sanding pad 6face.
3. Hold the pad with one hand to keep it fromrotating.
4. With the other hand, align the holes and place the
disc9 directly on top of thepad.
NOTE: These sanders are not to be used in drywall
applications. Using a sanding screen (e.g., screen used for
sanding drywall) directly on the hook and loop pad will not
hold and will damage the hooks on the pad. The hooks on
the pad will wear very rapidly if left in contact with the work
surface while the tool isoperating.

Switch (Fig. A)
To turn the unit on, depress the side of the dust-protected
switch 1 that corresponds to the symbol “I”. To turn the
tool off, depress the side of the switch that corresponds to
the symbol “O”.
Speed Control Dial (Fig. A)
The speed control dial 2, shown in FigureA, allows you
to increase or decrease speed from 8000–12000 Orbits Per
Minute. The optimal speed setting for each application is
very much dependent on personal preference. Generally,
you will want to use a higher setting on harder materials
and a lower setting on softer materials. Material removal
rate increases as speedincreases.
Dust Extraction (Fig. E, H)
Your sander has two dust extraction methods: a built-in
dust port 3 which allows either the supplied dust bag4
or a shop vacuum system to be connected; and a dust skirt
(11, Fig.H). The built-in dust port utilizes the
DeWALT
AirLock connection making it compatible with the
DeWALT
dustextractors.
To Attach the Dust Bag (Fig. E)
1. While holding the sander, fit the dust bag collar 5 to
the dust port 3 as shown in FigureE.
2. Turn the collar 5 clockwise to lock the dust bag 4
inplace.

To Empty the Dust Bag (Fig. E)
1. While holding the sander, turn the collar 5
counterclockwise to unlock the dust bag 4.
2. Remove dust bag from the sander and gently shake or
tap the dust bag toempty.
3. Reattach the dust bag back onto the dust port and lock
into place by turning the dust bag collarclockwise.
You may notice that all the dust will not come free from
the bag. This will not affect sanding performance but will
reduce the sander’s dust collection efficiency. To restore
your sander’s dust collection efficiency, depress the spring
inside the dust bag when you are emptying it and tap it on
the side of the trash can or dustreceptacle.
CAUTION: Never operate this sander unless a
dust collector is in place. Sanding dust exhaust may
create a breathinghazard.
OPERATION
WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start-up can causeinjury.

Installing and Removing the Battery Pack
(Fig. F)
NOTE: For best results, make sure your battery pack is
fullycharged.
To install the battery pack 7 into the tool handle, align the
battery pack with the rails inside the tool’s handle and slide
it into the handle until the battery pack is firmly seated in
the tool and ensure that it does notdisengage.
To remove the battery pack from the tool, press the release
button 8 and firmly pull the battery pack out of the tool
handle. Insert it into the charger as described in the charger
section of thismanual.

Proper Hand Position (Fig. G)
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 grip
asshown.
Fig. G
Operating the Sander (Fig. G)
NOTICE:These sanders are not to be used in
drywallapplications.
NOTICE:Avoid overloading your sander. Overloading
will result in a considerable reduction in speed and
finish quality of your work. The unit may also become
hot. In this event, run sander at a no load condition for
a minute ortwo.
To operate your sander, grasp it as shown in Figure G and
turn it on. Move the sander in long, sweeping strokes along
the surface being sanded, letting the sander do thework.
Pushing down on the tool while sanding actually slows
the removal rate and produces an inferior quality surface.
Be sure to check your work often, this sander is capable of
removing material rapidly, especially with coarsepaper.
The random orbital action of your sander allows you to sand
with the grain or at any angle across it for most sanding
jobs. To produce the best finish possible, start with coarse
grit sandpaper and change gradually to finer and finer
paper. Vacuum and wipe surface with a tack cloth between
grit steps. Your sander is designed to sand into small or
confined areas. Its small size and light weight make it ideal
for overheadwork.
The rate at which the dust collection bag fills up will vary
with the type of material being sanded and the coarseness
of the sandpaper. For best results, empty the bag frequently.
When sanding painted surfaces, (see the following for
additional precautions when sanding paint) you may
find that the sandpaper loads up and clogs with paint. A
heat gun will work much better to remove paint before
sanding. FOLLOW ALL SAFETY INSTRUCTIONS IN HEAT GUN
INSTRUCTIONMANUAL.
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.
-NO EATING, DRINKING or SMOKING should be done
in the work area to prevent ingesting contaminated
paint particles. Workers should wash and clean up
BEFORE eating, drinking or smoking. Articles of food,
drink, or smoking should not be left in the work area
where dust would settle onthem.
2. ENVIRONMENTAL SAFETY
-Paint should be removed in such a manner as to
minimize the amount of dustgenerated.
-Areas where paint removal is occurring should be
sealed with plastic sheeting of 4 milsthickness.

10
-Sanding should be done in a manner to reduce
tracking of paint dust outside the workarea.
3. CLEANING AND DISPOSAL
-All surfaces in the work area should be vacuumed
and thoroughly cleaned daily for the duration of
the sanding project. Vacuum filter bags should be
changedfrequently.
-Plastic drop cloths should be gathered up and
disposed of along with any dust chips or other
removal debris. They should be placed in sealed
refuse receptacles and disposed of through regular
trash pick-up procedures. During clean up, children
and pregnant women should be kept away from the
immediate workarea.
-All toys, washable furniture and utensils used by
children should be washed thoroughly before being
usedagain.
MAINTENANCE
WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start-up can causeinjury.
Replacing the Sanding Pad and the Belt
(Fig. H)
Your sander is equipped with a replaceable belt 10 which
is located between the pad 6 and the sander body 12.
It is designed to control the pad speed while the unit is
off the work surface. The belt and the sanding pad 6 are
designed to be consumable parts and will occasionally need
to be replaced. The sanding pad needs replacement when
signs of wear become evident. Replacement of the belt is
necessary when the pad speed increases very dramatically
when the unit is lifted from the work surface. These parts are
available at extra cost from your local dealer or authorized
DeWALT
servicecenter.
1. Holding the platen firmly, remove the four screws 13
from the bottom of thepad.
2. Remove the pad 6.
3. Replace worn or damaged belt 10 by wrapping it
around the shoulder screw 14 and bearing retainer 15
as shown in FigureH.
4. Reinstall pad (replace with new pad if necessary).
Replace the four screws 13. Be careful not to over-
tightenscrews.
