The declared vibration emission value has been
measured in accordance with a standard test
method and may be used for comparing one tool
with another.
The declared vibration emission value may also be
used in a preliminary assessment of exposure.
WARNING: The vibration emission
value during actual use of the power
tool can differ from the declared value
depending on the ways in which the tool
is used. This could lead to a significant
underestimate of exposure when the
tool is used regularly in such a way.
An estimation of the level of exposure to vibration
experienced during a given period of work should
also take into account the times when the tool is
switched off and when it is running idle in addition to
the trigger time.
This may significantly reduce the exposure level over
the total working period.

WARNING: To reduce the risk of injury,
read the instruction manual.
General Safety Rules
WARNING! Read all instructions. Failure
to follow all instructions listed below
may result in electric shock, fire and/or
serious injury.
The term “power tool” in all of the warnings listed
below refers to your mains-operated (corded) power
tool or battery-operated (cordless) power tool.
SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTURE REFERENCE.
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 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.
ENGLISH
32
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,
clothing and gloves 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
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 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 tools 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.
5) BATTERY TOOL USE AND CARE
a) Ensure the switch is in the off position
before inserting battery pack. Inserting the
battery pack into power tools that have the
switch on invites accidents.
b) 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.
c) Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of
injury and fire.
d) 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.
e) 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.
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.

Additional Specifi c Safety Rules
a) This power tool is intended to function
as a grinder, sander, wire brush, polisher
or cut-off tool. 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.
b) Do not use accessories which are not
specifically designed and recommended
by the tool manufacturer. Just because the
accessory can be attached to your power tool,
it does not assure safe operation.
c) The rated speed of the accessory must be at
least equal to the maximum speed marked
on the power tool. Accessories running faster
than their rated speed can break and fly apart.
d) The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized
accessories cannon be adequately guarded or
controlled.
ENGLISH
34
e) The arbour size of wheels, flanges, backing
pads or any other accessory must properly
fit the spindle of the power tool. Accessories
with arbour holes that do not match the
mounting hardware of the power tool will run
out of balance, vibrate excessively and may
cause loss of control.
f) 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.
g) 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.
h) 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.
i) Hold power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact
hidden wiring or its own cord. Cutting
accessory contacting a “live” wire may make
exposed metal parts of the power tool “live” and
shock the operator.
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
powered 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.
Safety Warnings Specifi c for
Grinding and Abrasive Cutting-off
Operations
a) Use only wheel types that are recommended
for your power tool and the specific guard
designed for the selected wheel. Wheels for
which the power tool was not designed cannot
be adequately guarded and are unsafe.
b) The guard must be securely attached
to the power tool and positioned for
maximum safety, so the least amount of
wheel is exposed towards the operator. The
guard helps to protect operator from broken
wheel fragments and accidental contact with
wheel.
c) Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-off wheel. Abrasive cut-off
wheels are intended for peripheral grinding, side
forces applied to these wheels may cause them
to shatter.
d) Always use undamaged wheel flanges
that are of correct size and shape for your
selected wheel. Proper wheel flanges support
the wheel thus reducing the possibility of wheel
breakage. Flanges for cut-off wheels may be
different from grinding wheel flanges.
e) Do not use worn down wheels from larger
power tools. Wheel intended for larger power
tool is not suitable for the higher speed of a
smaller tool and may burst.
Causes and Operator Prevention
of Kickback
Kickback is a sudden reaction to a pinched,
bound or misaligned wheel, wire brush or flap
ENGLISH
35
disc causing an uncontrolled cut-off tool to
lift up and out of the workpiece toward the
operator.
When the wheel is pinched or bound tightly by
the workpiece, the wheel stalls and the motor
reaction drives the unit rapidly back toward or
away from the operator.
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:
Maintain a firm grip with both hands on the
unit and position your body and arm to allow
you to resist kickback forces. Kickback forces
can be controlled by the operator, if proper
precautions are taken.
When wheel is binding, or when interrupting
a cut for any reason, release the trigger and
hold the unit motionless in the material until
the wheel comes to a complete stop. Never
attempt to remove the unit from the work
or pull the unit backward while the wheel is
in motion or kickback may occur. Investigate
and take corrective actions to eliminate the
cause of wheel binding.
When restarting a cut-off tool in the
workpiece, check that the wheel is not
engaged into the material. If wheel is binding,
it may walk up or kickback from the workpiece
as the tool is restarted.
Support large panels to minimize the risk of
wheel pinching and kickback. Large panels
tend to sag under their own weight. Support
must be placed under the panel on both sides,
near the line of cut and near the edge of the
panel.

To unlock the trigger switch, press the lock-off
button. When the lock-off button is depressed to the
unlock icon, the unit is unlocked. The lock-off button
is colored red to indicate when the switch is in its
unlocked position.
Pull the trigger switch (a) to turn the tool ON.
Releasing the trigger switch turns the tool OFF.
NOTE: This tool has no provision to lock the switch in
the ON position, and should never be locked ON by
any other means.
CAUTION: Hold the side handle and
body of the tool firmly to maintain
control of the tool at start up and during
use and until the wheel or accessory
stops rotating. Make sure the wheel has
come to a complete stop be fore laying
the tool down.
CAUTION: Allow the tool to reach full
speed before touching tool to the work
surface. Lift the tool from the work
surface before turning the tool off.
SPINDLE LOCK
The spindle lock pin is provided to prevent the
spindle from rotating when installing or removing
wheels. Operate the spindle lock pin only when the
tool is turned off, the battery is removed, and the
wheel has come to a complete stop.
CAUTION: To reduce the risk of
damage to the tool, do not engage the
spindle lock while the tool is operating.
Damage to the tool will result and
attached accessory may spin off
possibly resulting in injury.
To engage the lock, depress the spindle lock button
and rotate the spindle until you are unable to rotate
the spindle further.
Mounting and Using Depressed
Center Grinding Wheels and
Sanding Flap Discs
MOUNTING AND REMOVING HUBBED WHEELS (FIG. 6)
WARNING: To reduce the risk of
serious personal injury, turn tool off and
remove battery pack before making
any adjustments or removing/installing
attachments or accessories.
Hubbed wheels install directly on the M14 threaded
spindle.
1. Thread the wheel on the spindle by hand.
ENGLISH
39
2. Depress the spindle lock button and use a
wrench to tighten the hub of the wheel.
3. Reverse the above procedure to remove the
wheel.
CAUTION: Failure to properly seat
the wheel before turning the tool on
may result in damage to the tool or the
wheel.
MOUNTING NON-HUBBED WHEELS (FIG. 7)
WARNING: To reduce the risk of
serious personal injury, turn tool off and
remove battery pack before making
any adjustments or removing/installing
attachments or accessories.
Depressed center Type 27 grinding wheels must be
used with included flanges.
1. Install the anti-lockup backing flange (f) on
spindle (r) with the raised centre against the
wheel. Be sure the backing flange recess is
seated onto the flats of the spindle by pushing
and twisting the flange before placing the
wheel (s).
2. Place wheel against the backing flange,
centering the wheel on the raised centre of the
backing flange.
3. While depressing the spindle lock button, thread
the clamp nut (g) on spindle. If the wheel you
are installing is more than 3.17 mm (1/8") thick,
place the threaded clamp nut on the spindle so
that the raised centre fits into the center of the
wheel (Fig. 7A). If the wheel you are installing is
3.17 mm (1/8") thick or less, place the threaded
clamp nut on the spindle so that the raised
centre is not against the wheel (Fig. 7B).
4. While depressing the spindle lock button,
tighten the clamp nut with a wrench.
5. To remove the wheel, depress the spindle lock
button and loosen the threaded clamp nut with
a wrench.
NOTE: If the wheel spins after the clamp nut is
tightened, check the orientation of the threaded
clamp nut. If a thin wheel is installed with the pilot on
the clamp nut against the wheel, it will spin because
the height of the pilot prevents the clamp nut from
holding the wheel.
SURFACE GRINDING WITH GRINDING WHEELS
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. Apply minimum pressure to the work surface,
allowing the tool to operate at high speed.
Grinding rate is greatest when the tool operates
at high speed.
3. Maintain a 20˚ to 30˚ angle between the
tool and work surface.
4. Continuously move the tool in a forward and
back motion to avoid creating gouges in the
work surface.
5. Remove the tool from work surface before
turning tool off. Allow the tool to stop rotating
before laying it down.
EDGE GRINDING WITH GRINDING WHEELS
WARNING: Wheels used for cutting
and edge grinding may break or kick
back if they bend or twist while the tool
is being used to do cut-off work or deep
grinding. To reduce the risk of serious
injury, limit the use of these wheels with
a standard Type 27 guard to shallow
cutting and notching [less than 13 mm
(1/2") in depth]. The open side of the
guard must be positioned away from
the operator. For deeper cutting with
a Type 1 cut-off wheel, use a closed
Type 1 guard.
1. Allow the tool to reach full speed before
touching the tool to the work surface.
2. Apply minimum pressure to the work surface,
allowing the tool to operate at high speed.
Grinding rate is greatest when the tool operates
at high speed.
3. Position yourself so that the open-underside of
the wheel is facing away from you.
4. Once a cut is begun and a notch is established
in the workpiece, do not change the angle of
the cut. Changing the angle will cause the wheel
to bend and may cause wheel breakage. Edge
grinding wheels are not designed to withstand
side pressures caused by bending.
5. Remove the tool from the work surface before
turning the tool off. Allow the tool to stop
rotating before laying it down.
WARNING: Do not use edge grinding/
cutting wheels for surface grinding
applications because these wheels
are not designed for side pressures
encountered with surface grinding.
Wheel breakage and serious personal
injury may result.

Precautions To Take When
Sanding Paint
1. 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.
2. 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:
PERSONAL SAFETY
1. No children or pregnant women should enter
the work area where the paint sanding is
being done until all clean up is completed.
2. 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.
NOTE: Only those dust masks suitable for
working with lead paint dust and fumes should
be used. Ordinary painting masks do not offer
this protection. See your local hardware dealer
for the proper N.I.O.S.H. approved mask.
3. 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.
ENVIRONMENTAL SAFETY
1. Paint should be removed in such a manner as
to minimize the amount of dust generated.
2. Areas where paint removal is occurring should
be sealed with plastic sheeting of 4 mils
thickness.
3. Sanding should be done in a manner to reduce
tracking of paint dust outside the work area.
CLEANING AND DISPOSAL
1. 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.
2. 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.
3. All toys, washable furniture and utensils used by
children should be washed thoroughly before
being used again.
MAINTENANCE
Your DEWALT 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.
Lubrication

than those offered by DEWALT, have
not been tested with this product, use
of such accessories with this tool could
be hazardous. To reduce the risk of

22.2 mm (7/8") arbor hole. If it does not,
it may have been designed for a circular
saw. Accessory ratings must always
be above tool speed as shown on tool
nameplate.
It is important to choose the correct guards, backing
pads and flanges to use with grinder accessories.
Consult your dealer for further information on the
appropriate accessories.
