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 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 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.

SAFETY INSTRUCTIONS FOR ALL
OPERATIONS
Safety Warnings Common for Grinding,
Sanding, Wire Brushing, Surface Finishing,
or Abrasive Cutting‑Off Operations
a ) This power tool is intended to function as a
grinder, sander, wire brush, surface finishing,
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 cannot
be adequately guarded orcontrolled.
e ) Threaded mounting of accessories must match
the grinder spindle thread. For accessories
mounted by flanges, the arbor hole of the
accessory must fit the locating diameter of the
flange. Accessories 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 wheels 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 ) 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) 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.

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.
Safety Warnings Specific 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 grinding surface of center depressed wheels
must not be mounted below the plane of the
guard lip. An improperly mounted wheel that
projects through the plane of the guard lip cannot be
adequatelyprotected.
c ) 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 the operator
from broken wheel fragments, accidental contact with
wheel and sparks that could igniteclothing.
d ) 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.
e ) 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.
f ) 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.
Additional Safety Warnings Specific for
Abrasive Cutting‑Off Operations
a ) Do not “jam” the cut‑off wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases the
loading and susceptibility to twisting or binding of
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 the 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 could give the operator an
electricshock.
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.
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

Additional Safety Information
WARNING: Never modify the power tool or any part of
it. Damage or personal injury couldresult.
WARNING: ALWAYS use safety glasses. Everyday
eyeglasses are NOT safety glasses. Also use face or
dust mask if cutting operation is dusty. ALWAYS WEAR
CERTIFIED SAFETYEQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratoryprotection.
WARNING:
Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to the State
of California to cause cancer, birth defects or
other reproductive harm. Some examples of these
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.
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.
WARNING: Always wear proper personal hearing
protection that conforms to ANSI S12.6 (S3.19)
during use. Under some conditions and duration
of use, noise from this product may contribute to
hearingloss.
• 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. Direct particles away from face
andbody.
• Use the appropriate dust extractor vacuum to remove
the vast majority of static and airborne dust. Failure
to remove static and airborne dust could contaminate the
working environment or pose an increased health risk to
the operator and those in closeproximity.
• Use clamps or other practical ways to secure and
support the workpiece to a stable platform. Holding
the work by hand or against your body is unstable and may
lead to loss ofcontrol andinjury.
• Do not use Type 11(flaring cup) wheels on this tool.
Using inappropriate accessories can result ininjury.
• Always use auxiliary handle. Tighten the handle
securely. The auxiliary handle should always be used to
maintain control of the tool at alltimes.
the wheel in the cut and the possibility of kickback or
wheelbreakage.
b ) Do not position your body in line with and behind
the rotating wheel. When the wheel, at the point of
operation, is moving away from your body, the possible
kickback may propel the spinning wheel and the power
tool directly atyou.
c ) When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes
to a complete stop. Never attempt to remove the
cut‑off wheel from the cut while the wheel is in
motion; otherwise kickback may occur. Investigate
and take corrective action to eliminate the cause of
wheelbinding.
d ) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully reenter the cut. The wheel may bind,
walk up or kickback if the power tool is restarted in
theworkpiece.
e ) Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own
weight. Supports must be placed under the workpiece
near the line of cut and near the edge of the workpiece
on both sides of thewheel.
f ) Use extra caution when making a “pocket cut”
into existing walls or other blind areas. The
protruding wheel may cut gas or water pipes, electrical
wiring or objects that can causekickback.
Safety Warnings Specific 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.
Safety Warnings Specific for Wire
BrushingOperations
a ) Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive load to
the brush. The wire bristles can easily penetrate light
clothing and/orskin.
b ) Guard must be used for wire brushing, do not
allow any interference of the wire wheel or brush
with the guard. Wire wheel or brush may expand in
diameter due to work and centrifugalforces.

• When starting the tool with a new or replacement
wheel, or a new or replacement wire brush installed,
hold the tool in a well protected area and let it run for
one minute. If the wheel has an undetected crack or flaw,
it should burst in less than one minute. If the wire brush has
loose wires, they will be detected. Never start the tool with a
person in line with the wheel. This includes theoperator.
• To prevent the spindle end from contacting the
bottom of the hole of the hubbed wheel, use
accessories that have a threaded hole depth of
at least 21mm. Failure to use an accessory with the
appropriate thread depth could result in damage to the
hubbed wheel and injury to the operator or persons in
thearea.
• Avoid bouncing the wheel or giving it rough
treatment. If this occurs, stop the tool and inspect the
wheel for cracks orflaws.
• Always handle and store wheels in a carefulmanner.
• Do not operate this tool for long periods of time.
Vibration caused by the operating action of this tool may
cause permanent injury to fingers, hands, and arms. Use
gloves to provide extra cushion, take frequent rest periods,
and limit daily time ofuse.
• Safety goggles or safety glasses with side shields and
a full face shield compliant with ANSI Z87.1 MUST be
worn by the operator and others that are within 50'
(15.2 m) of the use of thisproduct.
• Air vents often cover moving parts and should be
avoided. Loose clothes, jewelry or long hair can be caught
in movingparts.
• 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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

Flanges and Wheels
WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start‑up can causeinjury.
WARNING: Accessories must be rated for at least
the speed recommended on the tool warning label.
Wheels and other accessories running over their
rated accessory speed may fly apart and cause injury.
Threaded accessories must have a 5/8"‑11 hub. Every
unthreaded accessory must have a 7/8" (22 mm) arbor
hole. If it does not, it may have been designed for a
circular saw and should not be used. Use only the
accessories shown in the Accessories Chart of this
manual. Accessory ratings must always be above tool
speed as shown on toolnameplate.
WARNING:Handle and store all abrasive wheels
carefully to prevent damage from thermal shock, heat,
mechanical damage, etc. Store in a dry protected area
free from high humidity, freezing temperatures or
extreme temperaturechanges.
Mounting Non‑Hubbed Wheels (Fig.F–H)
WARNING: Failure to properly seat the flanges and/or
wheel could result in serious injury (or damage to the
tool orwheel).
CAUTION: Included flanges must be used with
depressed center Type 27/42 grinding wheels and
Type1/41 cutting wheels. Refer to the Accessories
Chart for moreinformation.
WARNING: A closed, two‑sided cutting wheel guard
is required when using abrasive cutting wheels or
diamond‑coated cutting wheels.
WARNING: Use of a damaged flange or guard or
failure to use proper flange and guard can result in
injury due to wheel breakage and wheel contact. Refer
to the Accessories Chart for moreinformation.
1. Place the tool on a table, guardup.
2. Fit the inner backing flange4 correctly onto the
spindle2 (Fig.F).
3. Place the wheel14 on the backing flange 4. When
fitting a wheel with a raised center, make sure that the
raised center15 is facing the backing flange4.
4. While depressing the spindle lock button 1 and with the
raised center facing toward the wheel, thread the locking
flange5 onto the spindle.
a. If the wheel you are installing is 3.0 mm (1/8") thick
or less, place the threaded locking flange5 on the
spindle so that the raised section (pilot) is not against
thewheel (Fig.H2).
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.
Guards
CAUTION: Guards must be used with all grinding
wheels, cutting wheels, sanding flap discs, wire
brushes, and wire wheels. The tool may be used
without a guard only when sanding with conventional
sanding discs. Refer to Figure A to see guards provided
with the unit. Some applications may require
purchasing the correct guard from your local dealer or
authorized servicecenter.
NOTE: Edge grinding and cutting can be performed with
Type 27wheels designed and specified for this purpose; 1/4"
(6.35 mm) thick wheels are designed for surface grinding
while thinner Type 27wheels need to be examined for
the manufacturer's label to see if they can be used for
surface grinding or only edge grinding/cutting. A Type 1/41
guard must be used for any wheel where surface grinding

Precautions To Take When Working on a
Painted Workpiece
1. Sanding or wire brushing 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 or wire brushing 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.
wheel, it will spin because the height of the pilot prevents
the clamp nut from holding thewheel.
To perform work on the surface of a workpiece:
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. Material removal rate is
greatest when the tool operates at highspeed.
Angle
3. Maintain an appropriate angle between the tool
and work surface. Refer to the chart according to
particularfunction.
Function Angle
Grinding 20˚-30˚
Sanding with Flap Disc 5˚-10˚
Sanding with Backing Pad 5˚-15˚
Wire Brushing 5˚-10˚
4. Maintain contact between the edge of the wheel and the
worksurface.
‑If grinding, sanding with flap discs or wire brushing,
move the tool continuously in a forward and back
motion to avoid creating gouges in the worksurface.
‑If sanding with a backing pad, move the tool
constantly in a straight line to prevent burning and
swirling of worksurface.
NOTE: Allowing the tool to rest on the work surface without
moving will damage the workpiece.
5. Remove the tool from work surface before turning tool
off. Allow the tool to stop rotating before laying itdown.
CAUTION: Use extra care when working over an
edge, as a sudden sharp movement of grinder may
beexperienced.
Surface Grinding, Sanding and
WireBrushing
CAUTION:Always use the correct guard per the
instructions in thismanual.
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
Spindle Lock (Fig.A)
The spindle lock button1 is provided to prevent the spindle
from rotating when installing or removing wheels. Operate
the spindle lock only when the tool is turned off, unplugged
from the power supply, and has come to a completestop.
NOTICE: 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

switch is released. To unlock the tool, depress and release the
paddle switch. This will cause the tool tostop.
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.
Paddle Switch (Fig.A)
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 before laying the tooldown.
CAUTION: Before connecting the tool to a power
source, depress and release the paddle switch once
without depressing the lock‑on lever to ensure that the
switch is off. Depress and release the paddle switch as
described above after any interruption in power supply
to the tool, such as the activation of a ground fault
interrupter, throwing of a circuit breaker, accidental
unplugging, or power failure. If the paddle switch is
locked on, the tool will start unexpectedly when it
isreconnected.
NOTE: To reduce unexpected tool movement, do not switch
the tool on or off while under load conditions. Allow the
grinder to run up to full speed before touching the work
surface. Lift the tool from the surface before turning the tool
off. Allow the tool to stop rotating before putting itdown.
1. To turn the tool on, push the lock-off lever9 toward the

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.
Edge Grinding and Cutting
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 injury
mayresult.
CAUTION:Wheels used for edge grinding and
cutting may break or kick back if they bend or twist
while the tool is being used. In all edge grinding/
cutting operations, the open side of the guard must be
positioned away from theoperator.
NOTICE: Edge grinding/cutting with a Type27wheel
must be limited to shallow cutting and notching—less
than 1/2" (13mm) in depth when the wheel is new.
Reduce the depth of cutting/notching equal to the
reduction of the wheel radius as it wears down. Refer
to the Accessories Chart for more information. Edge
grinding/cutting with a Type 1/41wheel requires usage
of a Type 1/41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/cutting 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.
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

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mm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

transporter l’outil. Transporter un outil électrique
alors que le doigt repose sur l’interrupteur ou brancher
un outil électrique dont l’interrupteur est à la position
de marche risque de provoquer unaccident.
d ) Retirer toute clé de réglage ou clé avant de
démarrer l’outil. Une clé ou une clé de réglage
attachée à une partie pivotante de l’outil électrique
peut provoquer des blessurescorporelles.
e ) Ne pas trop tendre les bras. Conserver son
équilibre en tout temps. Cela permet de mieux
maîtriser l’outil électrique dans les situationsimprévues.
f ) S’habiller de manière appropriée. Ne pas porter
de vêtements amples ni de bijoux. Garder les
cheveux, les vêtements et les gants à l’écart des
pièces mobiles. Les vêtements amples, les bijoux ou
les cheveux longs risquent de rester coincés dans les
piècesmobiles.
g ) Si des composants sont fournis pour le
raccordement de dispositifs de dépoussiérage
et de ramassage, s’assurer que ceux‑ci sont bien
raccordés et utilisés. L’utilisation d’un dispositif de
dépoussiérage peut réduire les dangers engendrés par
lespoussières.
h ) Ne pas laisser votre connaissance acquise suite
l’utilisation fréquente des outils vous permettre
de baisser la garde et ignorer les principes de
sécurité de l’outil. Un acte irréfléchi peut causer une
blessure grave en une fraction deseconde.
4) Utilisation et entretien d’un
outilélectrique
a ) Ne pas forcer un outil électrique. Utiliser l’outil
électrique approprié à l’application. L’outil
électrique approprié effectuera un meilleur travail,
de façon plus sûre et à la vitesse pour laquelle il a
étéconçu.
b ) Ne pas utiliser un outil électrique dont
l’interrupteur est défectueux. Tout outil électrique
dont l’interrupteur est défectueux est dangereux et doit
êtreréparé.
c ) Débranchez la fiche de la prise électrique et, si
amovible, retirez le bloc‑piles de l’outil avant
d’effectuer tout ajustement, changement et
entreposage de celui‑ci. Ces mesures préventives
réduisent les risques de démarrage accidentel de
l’outilélectrique.
d ) Ranger les outils électriques hors de la portée
des enfants et ne permettre à aucune personne
n’étant pas familière avec un outil électrique ou
son mode d’emploi d’utiliser cet outil. Les outils
électriques deviennent dangereux entre les mains
d’utilisateursinexpérimentés.

coupé ou accroché et votre main ou votre bras peut
être happé par l’accessoire enrotation.
k ) Ne jamais déposer l’outil électrique avant que
l’accessoire soit complètement arrêté. L’accessoire
en rotation peut accrocher la surface et vous faire
perdre le contrôle de votre outilélectrique.
l ) Ne pas faire fonctionner l’outil électrique pendant
que vous le transportez à vos côtés. Un contact
accidentel avec l’accessoire en rotation pourrait
accrocher vos vêtements, tirant l’accessoire dans
votrecorps.
m ) Nettoyez régulièrement les évents de l’outil
électrique. Le ventilateur du moteur produit de la
poussière à l’intérieur du boîtier et l’accumulation
excessive de métal fritté peut causer des
chocsélectriques.
n ) Ne pas utiliser l’outil électrique près de matières
inflammables. Des étincelles pourraient enflammer
cesmatières.
o ) Ne pas utiliser des accessoires qui nécessitent des
liquides réfrigérants. Utiliser de l’eau ou d’autres
liquides réfrigérants peut entraîner une électrocution
ou un chocélectrique.
Rebond et avertissements associés
Le rebond est une réaction soudaine d’une meule, d’un tampon,
d’une brosse ou tout autre accessoire en rotation coincée ou
accrochée. Le coinçage ou l’accrochage entraîne un blocage
rapide de l’accessoire en rotation qui à son tour fait en sorte
que l’outil électrique non contrôlé soit forcé dans la direction
opposée de la rotation de l’accessoire au point depincement.
Par exemple, si une meule abrasive est accrochée ou coincée
dans la pièce de travail, le bord de la meule qui est entré dans
le point de coincement peut creuser la surface du matériau
causant la chute ou l’éjection de la meule. La meule peut bondir
vers ou loin de l’utilisateur, selon la direction du mouvement de
la meule au point de pincement. Les meules abrasives peuvent
aussi se briser dans cesconditions.
Le rebond est le résultat d’une mauvaise utilisation de l’outil
et/ou de procédures ou de conditions de fonctionnement
incorrectes et il peut être évité prenant les précautions
appropriées définies ci‑dessous :
a ) Maintenez solidement l’outil électrique et placez
votre corps et votre bras pour vous permettre de
résister aux forces de rebond. Utilisez la poignée
auxiliaire, si fournie, pour un contrôle maximum
sur le rebond ou la réaction de couple durant
le démarrage. L’utilisateur peut contrôler les forces
du rebond ou la réaction de couple si les précautions
appropriées sontprises.
b ) Ne jamais placer votre main près de l’accessoire
en rotation. L’accessoire peut rebondir sur votremain.
c ) Ne pas placer votre corps dans la zone où l’outil
électrique se déplacera si un rebond se produit. Un
rebond projettera l’outil dans la direction opposée du
mouvement de la meule au pointd’accrochage.
nominale de votre outil. Les accessoires ayant
un format incorrect ne peuvent pas être gardés ou
contrôlés de façonappropriée.
e ) Le montage fileté des accessoires doit
correspondre au filet de tige de la meuleuse.
Pour les accessoires fixés par des brides, l’alésage
central de l’accessoire doit correspondre au
diamètre de repérage de la bride. Les accessoires
qui ne correspondent pas au matériel de montage de
l’outil électrique manqueront d’équilibre, vibreront
de façon excessive ou peuvent entraîner une perte
decontrôle.
f ) Ne pas utiliser un accessoire endommagé.
Avant chaque utilisation, inspectez l’accessoire
comme les meules abrasives pour des copeaux
et des fissures, la plaque de presse pour des
fissures, une déchirure ou une usure excessive,
la brosse métallique pour tout fil craqué ou
détaché. Si vous échappez l’outil ou un accessoire,
inspectez‑le pour des dommages ou installez un
accessoire non endommagé. Après avoir inspecté
et installé un accessoire, placez‑vous, ainsi que
les passants, à distance de la zone de rotation de
l’accessoire et faites fonctionner l’outil électrique
à la vitesse maximum à vide pendant une minute.
Les accessoires endommagés se brisent normalement
durant la durée dutest.
g ) Portez un équipement de protection individuelle.
Selon l’application, utilisez un masque de
protection ou des lunettes de sécurité. Selon
les besoins, portez un masque anti‑poussière,
une protection auditive, des gants et un tablier
d’atelier pouvant arrêter de petits fragments
de la pièce de travail ou abrasifs. La protection
des yeuxdoit être en mesure d’arrêter les débris
volants générés par diverses opérations. Le
masque antipoussière ou le respirateur doit être
en mesure de filtrer les particules générées par
votre utilisation. L’exposition prolongée à du bruit
d’intensité élevée peut causer une perteauditive.
h ) Gardez les passants à une distance sécuritaire
de l’aire de travail. Toute personne entrant dans
l’aire de travail doit porter un équipement de
protection individuel. Les fragments de la pièce à
travailler ou d’un accessoire brisé peuvent s’envoler
et peuvent causer une blessure au‑delà de l’aire
immédiate del’opération.
i ) Tenez l’outil électrique par les surfaces de prise
isolées seulement lorsque vous effectuez une
tâche où l’accessoire de coupe peut entrer en
contact avec le câblage dissimulé ou son propre
cordon. L’accessoire de coupe entrant un contact
avec un câble «sous tension» peut exposer les pièces
métalliques de l’outil électrique «sous tension» et
pourrait donner un choc électrique àl’utilisateur.
j ) Placez le cordon à l’écart de l’accessoire en
rotation. Si vous perdez le contrôle, le cordon peut être

b ) Ne pas placer votre corps en ligne avec et derrière
la meule en rotation. Lorsque la meule, au point
de fonctionnement, se déplace loin de votre corps, le
possible rebond peut projeter la meule en rotation et
l’outil électrique directement survous.
c ) Lorsque la meule se coince ou si vous cessez une
coupe pour quelque raison que ce soit, éteignez
l’outil électrique et tenez l’outil électrique
sans bouger jusqu’à ce que la meule s’arrête
complètement. Ne jamais tenter de retirer la
meule de coupe de la coupe pendant que la
meule est en mouvement sinon un rebond peut
se produire. Examinez‑la et prenez des mesures
correctives pour éliminer la cause du coincement de
lameule.
d ) Ne pas redémarrer la coupe dans la pièce à
travailler. Laissez la meule atteindre sa pleine
vitesse et entrez à nouveau dans la coupe. La
meule peut se coincer, s’approcher ou rebondir si l’outil
électrique est redémarré dans la pièce àtravailler.
e ) Soutenez les panneaux ou toute pièce à travailler
surdimensionnée afin de réduire le risque de
coincement ou de rebond de la meule. Les grosses
pièces à travailler ont tendance à s’affaisser sous
leur propre poids. Des supports doivent être placés
sous la pièce de travail près de la ligne de coupe et
près du bord de la pièce de travail des deux côtés de
lameule.
f ) Soyez très prudent lorsque vous faites une
«encoche» dans les parois actuelles ou d’autres
zones aveugles. La meule qui dépasse peut couper les
conduites d’eau ou de gaz, les câbles électriques ou des
objets qui peuvent causer unrebond.
Avertissements de sécurité spécifiques aux
opérations de sablage
a ) Ne pas utiliser des disques en papier
abrasif excessivement grands. Suivez les
recommandations du fabricant lorsque vous
sélectionnez le papier abrasif. Le papier abrasif
dépassant le patin de ponçage présente un risque de
lacération et peut causer l’accrochage, la déchirure du
disque ou lerebond.
Avertissements de sécurité spécifiques aux
opérations de brossage métallique
a ) Sachez que des poils métalliques peuvent être
projetés par la brosse même en utilisation
ordinaire. Ne pas trop forcer les poils en
appliquant une charge excessive sur la brosse. Les
poils métalliques peuvent facilement pénétrer dans les
vêtements légers et/ou lapeau.
b ) Si l’utilisation d’une protection est recommandée
pour la brosse métallique, ne pas permettre
d’interférence de la meule ou de la brosse
métallique avec la protection. La meule ou de la
brosse métallique peut s’élargir en raison du travail et
des forcescentrifuges.
d ) Faites attention lorsque vous travaillez dans
les coins, les bords coupants, etc. Évitez le
rebondissement ou l’accrochage de l’accessoire.
Les coins, les bords coupants ou le rebondissement ont
tendance à accrocher l’accessoire en rotation et causer
une perte de contrôle ou unrebond.
e ) Ne fixez pas une chaîne coupante, une lame pour
sculpture sur bois ou une lame de scie dentée.
Ces lames créent des rebonds fréquents et une perte
decontrôle.
Avertissements de sécurité spécifiques
aux opérations de meulage et de coupe
abrasive
a ) Utilisez seulement les meules recommandées
pour votre outil électrique et la protection conçue
pour la meule sélectionnée. Les meules qui ne sont
pas conçues pour l’outil électrique ne peuvent être
protégées convenablement et ne sont passécuritaires.
b ) La surface de meulage des meules à moyeu
déporté ne doit pas être installée en‑dessous du
plan de la lèvre de la protection. Une meule mal
installée qui projette à travers le rabot de la lèvre de la
protection ne peut pas bien êtreprotégée.
c ) La protection doit être fixée de façon sécuritaire
à l’outil électrique et placée pour une sécurité
maximale afin que le moins de la meule possible
soit exposé à l’utilisateur. La protection aide à
protéger l’utilisateur des fragments de la meule brisée,
du contact accidentel avec la meule et des étincelles
qui pourraient enflammer vosvêtements.
d ) Les meules doivent être utilisées seulement pour
les applications recommandées. Par exemple:
ne pas meuler avec le côté de la meule de coupe.
Les meules de coupe sont conçues pour le meulage
périphérique, les forces latérales appliquées sur ces
meules peuvent les faireéclater.
e ) Utilisez toujours des brides de meules non
endommagées ayant la bonne taille et la bonne
forme pour la meule sélectionnée. Les brides
de meules appropriées soutiennent la meule
réduisant ainsi la possibilité d’un bris de la meule.
Les brides pour les meules de coupe peuvent être
différentes des brides de meules demeulage.
f ) Ne pas utiliser des meules usées d’outils
électriques plus gros. La meule conçue pour les outils
électriques plus gros ne convient pas pour la vitesse
plus élevée d’un petit outil et peutéclater.
Avertissements de sécurité spécifiques aux
opérations de coupe abrasive
a ) Ne pas «bloquer» la meule de coupe ou appliquer
une pression excessive. Ne tentez pas de faire une
coupe de profondeur excessive. Surcharger le disque
augmente la charge et la prédisposition à la torsion ou
au coincement du disque dans la coupe et la possibilité
de rebond ou de rupture dudisque.
