GENERAL POWER TOOL SAFETY WARNINGS
WARNING READ ALL SAFETY WARNINGS AND INSTRUCTIONS.
Failure to follow the warnings and instructions may result in electric shock, fi re 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.
• Keep work area clean and well lit. Cluttered or
WORK AREA SAFETY
dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of fl ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
ELECTRICAL SAFETY
• 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. Unmodifi ed plugs and matching outlets will
reduce risk of electric shock.
• Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. W ater entering a power tool will increase
the risk of electric shock.
• 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.
• 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.
• 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.
PERSONAL SAFETY
• 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 infl uence of drugs, alcohol or medi-
cation. A moment of inattention while operating
power tools may result in serious personal injury.
• 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.
• 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 fi nger on the switch or energising power
tools that have the switch on invites accidents.
• 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.
• Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewellery. Keep your hair , clothing and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
• If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
these devices can reduce dust-related hazards.
POWER TOOL USE AND CARE
• 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.
• 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.
• 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.
• 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.
• Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
• 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.
SERVICE
• Have your power tool serviced by a qualifi ed
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.

SPECIFIC SAFETY RULES
Safety Warnings Common for Grinding, Sanding, Wire Brushing or Abrasive Cutting-Off
Operations:
• This power tool is intended to function as a
grinder, sander, wire brush or cut-off tool.
Read all safety warnings, instructions, illustrations and specifi cations provided with
this power tool. Failure to follow all instructions
listed below may result in electric shock, fi re and/
or serious injury.
• Operations such as polishing are not recom-
mended to be performed with this power tool.
Operations for which the power tool was not designed may create a hazard and cause personal
injury.
• Do not use accessories which are not specifi -
cally designed and recommended by the tool
manufacturer. Just because the accessory can
be attached to your power tool, it does not assure
safe operation.
• 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
fl y apart.
• 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.
• The arbour size of wheels, fl anges, backing
pads or any other accessory must properly
fi t 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.
• 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.
• Wear personal protective equipment. Depend-
ing on application, use face shield, safety
goggles or safety glasses. As appropriate,
wear dust mask, hearing protectors, gloves
and work shop apron capable of stopping
small abrasive or workpiece fragments. The
eye protection must be capable of stopping
fl ying debris generated by various operations.
The dust mask or respirator must be capable of
fi ltrating particles generated by your operation.
Prolonged exposure to high intensity noise may
cause hearing loss.
• 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 fl y away and cause injury beyond immediate
area of operation.
• 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.
• Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
• Never lay the power tool down until the ac-
cessory has come to a complete stop. The
spinning accessory may grab the surface and pull
the power tool out of your control.
• 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.
• 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.
• Do not operate the power tool near fl ammable
materials. Sparks could ignite these materials.
• 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 power tool misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below.
• Maintain a fi rm 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 reactions or
kickback forces, if proper precautions are taken.
3
• Never place your hand near the rotating accessory. Accessory may kick back over your hand.
• Do not position your body in the area where
power tool will move if kickback occurs. Kick-
back will propel the tool in direction opposite to
the wheel’s movement at the point of snagging.
• 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.
• 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:
• Use only wheel types that are recommended
for your power tool and the specifi c guard
designed for the selected wheel. Wheels for
which the power tool was not designed can not
be adequately guarded and are unsafe.
• 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.
• 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.
• Always use undamaged wheel fl anges that are
of correct size and shape for your selected
wheel. Proper wheel fl anges support the wheel
thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from
grinding wheel fl anges.
• 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 Specifi c for Abra-
sive Cutting-Off Operations:
• 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 the wheel in the cut and the possibility of kickback or wheel breakage.
• 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.
• 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 cor-
rective action to eliminate the cause of wheel
binding.
• 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.
• 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.
• Use extra caution when making a "pocketcut"
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 Specifi c for Sanding Opera-
tions:
• Do not use excessively oversized sanding disc
paper. Follow manufacturers 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 Specifi c for Wire Brushing
Operations:
• Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
over stress the wires by applying excessive
load to the brush. The wire bristles can easily
penetrate light clothing and/or skin.
• If the use of a guard is recommended 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 workload
and centrifugal forces.
Additional Safety Warnings
• Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.
• WARNING: Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to cause
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• lead from lead-based paint
• 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 fi lter out microscopic par-
ticles.

GROUNDING
WARNING Improperly connecting the
grounding wire can result in the risk of electric shock. Check with a qualifi ed electrician
if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug
provided with the tool. Never remove the
grounding prong from the plug. Do not use
the tool if the cord or plug is damaged. If
damaged, have it repaired by a MILWAUKEE
service facility before use. If the plug will not
fi t the outlet, have a proper outlet installed by
a qualifi ed electrician.
Grounded Tools:
Tools with Three Prong Plugs
Tools marked "Grounding Required" have a three
wire cord and three prong grounding plug. The
plug must be connected to a properly grounded
outlet (See Figure A). If the tool should electrically
malfunction or break down, grounding provides a
low resistance path to carry electricity away from
the user, reducing the risk of electric shock.
The grounding prong in the plug is connected
through the green wire inside the cord to the
grounding system in the tool. The green wire in the
cord must be the only wire connected to the tool's
grounding system and must never be attached to
an electrically "live" terminal.
Y our tool must be plugged into an appropriate outlet, properly installed and grounded in accordance
with all codes and ordinances.
The plug and outlet should
look like those in Figure A.
Double Insulated Tools:
Tools with Two Prong Plugs
Tools marked "Double Insulated" do not require
grounding. They have a special double insulation system which satisfi es OSHA requirements
and complies with the applicable standards of
Underwriters Laboratories,
Inc., the Canadian Standard Association and the
National Electrical Code.
Double Insulated tools may
be used in either of the
120 volt outlets shown in
Figures B and C.
Fig. A
Fig. B
Fig. C
EXTENSION CORDS
Grounded tools require a three wire extension
cord. Double insulated tools can use either a two
or three wire extension cord. As the distance from
the supply outlet increases, you must use a heavier
gauge extension cord. Using extension cords with
inadequately sized wire causes a serious drop in
voltage, resulting in loss of power and possible tool
damage. Refer to the table shown to determine the
required minimum wire size.
The smaller the gauge number of the wire, the
greater the capacity of the cord. For example, a 14
gauge cord can carry a higher current than a 16
gauge cord. When using more than one extension
cord to make up the total length, be sure each cord
contains at least the minimum wire size required. If
you are using one extension cord for more than one
tool, add the nameplate amperes and use the sum
to determine the required minimum wire size.
Guidelines for Using Extension Cords
• If you are using an extension cord outdoors,
be sure it is marked with the suffi x "W-A" ("W"
in Canada) to indicate that it is acceptable for
outdoor use.
• Be sure your extension cord is properly wired
and in good electrical condition. Always replace
a damaged extension cord or have it repaired by
a qualifi ed person before using it.
• Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.

To lock-on the switch (6122-30, 6122-30A,
6123-30 only), start the tool and push in the lock-on
button. To stop the tool, pull and release the trigger. Make sure the tool comes to a complete stop
before laying it down.
General Operation
1. If you have just installed an accessory or are
beginning a period of work, test it by letting it spin
for one minute before applying it to the workpiece.
Out-of-balance or damaged accessories can mar
workpiece, damage the tool, and cause stress that
may cause accessory failure.
2. Use a clamp, vise or other practical means to hold
your work, freeing both hands to control the tool.
3.Hold tool securely with both hands.
4. Start the tool.
5. Allow accessory to come to full speed before
beginning work.
6. Control pressure and surface contact between
accessory and workpiece. Too much pressure
slows speed.
7. When fi nished, turn off the tool and make sure it
comes to a complete stop before laying it down.

USING GRINDING WHEELS
WARNING To reduce the risk of injury ,
the operator should be instructed in the use,
care and protection of grinding wheels.
Grinding Wheel Selection
Use grinding wheels, and accessories that are:
• correct size as written on tool’s nameplate.
• rated at or above the RPM listed on the tool’s
nameplate.
• correct accessory, wheel type and grit for the job.
Grinding is the cutting action of thousands of abrasive grains on the face of a grinding wheel. When
grinding metals such as steel and iron, choose an
aluminum oxide grinding wheel. Select a silicon
carbide grinding wheel for stone and concrete. Use
cotton reinforced wheels for non-ferrous metals.
Type 27 Reinforced 1/8" thick or less Cut-Off
Wheels are suited for small cut-off and shallow
notching operations only. Always handle wheels
carefully to avoid damage. Before installing any
wheel, always inspect it for cracks. If wheel is
cracked, discard it to prevent others from using it.
Care of Grinding & Cut-Off Wheels
Grinding/cut-off wheels should be protected from:
• wetness and extreme humidity
• any type of solvent
• extreme changes in temperature
• dropping and bumping
Grinding and cut-off wheels should be stored:
• in an organized way so wheels can be removed
without disturbing or damaging other wheels
• with their safety information
Grinding and cut-off wheels should NOT be dropped,
rolled or bumped.
Discard wheels that have been dropped, rolled,
bumped, subjected to extreme changes in temperature, or come into contact with solvents or wetness.
Grinding
When grinding, hold tool at a 5o to 15o angle, using
constant pressure for a uniform fi nish. T oo great an
angle causes concentrated pressure on small areas
which may gouge or burn work surface.
Fig. 5
Hold at a
5° to 15° angle
For best result use only this portion of disc
USING CUT-OFF WHEELS
WARNING A Type "1" guard must be
installed when using a cut-off wheel to provide
maximum protection for the operator if the
wheel should break.
Type "1" Cut-Off Wheels are suited for small cut-of f
and shallow notching operations only.
When using a cut-off wheel, hold the tool as shown,
using only the edge of the wheel.
Fig. 6
WARNING Using the face of a Cut-Off
Wheel (as in grinding) will cause the Wheel
to crack and break, resulting in serious personal injury.
USING WIRE BRUSHES
WARNING Everyone in the area must
wear protective clothing and safety
goggles or face shields. Fatigued wires and
residue will fl y off the brush with considerable
force, causing potential for serious injury.
Wire brushes are useful for removing rust, scale,
burrs, weld slag, etc.
Always install wire cup brushes according to the
accessory manufacterer’s instructions.
Fig. 7
Wire Cup Brush
WARNING Because the wires on wire
wheel brushes are directed towards the
operator, a guard must be used to protect the
operator when fatigued wires break.
When using a wire wheel brush, install guard according to "Installing/Removing Accessories".

T est wheel for balance and loose or damaged wires
Hold at a
5° to 15° angle
by letting it spin for one minute before applying it
to the workpiece. During this time, no one should
stand in front of or in line with it.
Control pressure and surface contact between
wheel and workpiece. Too much pressure causes
over-bending of wires and heat build-up causing
premature wire breaking, rapid dulling and reduced
brush life. Instead of more pressure, try a wire wheel
with more aggressive cutting action (increased wire
size, decreased wire length or different brush type
(knot type vs.crimped wire type).
WARNING Never exceed Maximum
Safe Operating Speed of brush. Do not use
a damaged brush or one that is functioning
improperly (throwing wires, out-of-balance,
etc.). These conditions increase the possibility of further brush failure and possible
injury. Discard and replace damaged brushes
immediately.
USING SANDING DISCS
Sanding Disc Selection
Use sanding discs and accessories that are:
• correct size as written on tool’s nameplate.
• rated at or above the RPM listed on the tool’s
nameplate.
• correct accessory, wheel type and grit for the job.
Refer to the table below to select the correct type
of sanding disc for your job. Generally, use 24 or
36 grit for heavy stock removal; 50, 60, or 80 grit
for medium stock removal and 120 grit for fi nishing.
Always begin with a coarse grit, using successively
fi ner grits to obtain the desired fi nish. See your
MILWAUKEE Electric Tool Catalog for a complete
list of sanding discs.
Aluminum Oxide
For fast cutting, general purpose discs for most
metal jobs. Best for cold-rolled steel, stainless
steel or metals requiring tough, fast cutting, long
lasting abrasives.
Aluminum Zirconia Bi-Cut
Unique grit pattern is arranged in clusters for faster stock removal and cleaning. Ideal for removing
paint from cars, boats, etc. without clogging.
Ceramic
Lasts up to 3 times longer than Aluminum Oxide Discs. For general metal working. Ideal for
tough jobs.
Installing Backing Pad and Sanding Discs
1. Unplug the tool.
2. Wipe the accessories, disc nut and spindle to
remove dust and debris. Inspect the parts for
damage. Replace if needed.
3. Slip backing pad onto spindle with fl at side away
from gear case.

4. Place sanding disc on backing pad and secure
assembly to spindle with disc nut.
5. To tighten, press the spindle lock button while
turning disc nut clockwise with the spanner
wrench provided.
6. To remove backing pad and sanding disc, unplug
the tool and reverse the procedure.
Sanding
Hold tool at 5° to 15° angle to ensure proper sanding
pressure and control. Too great an angle will result
in too much pressure and could cause excessive
wear to the disc and workpiece. Too small an angle
will reduce control.
Use long, sweeping, side to side strokes, advancing
forward to produce the desired fi nish.
Fig. 10
Hold at a
5° to 15° angle
For best result use only this portion of disc
Cross Sanding
When fi nishing a surface that has been prepared by
a coarse disc or wheel, sand at right angles to the
strokes made by the coarser disc. Finishing marks
left from previous sanding are easily seen and
removed for a uniform fi nish. Failure to cross sand
when changing from a coarse disc to a fi nishing disc
may result in deep scratches and circular marks.
10
Removing Welds or Hammer Marks
When removing welds or hammer marks, limit
coarse sanding to the immediate area. Use successively fi ner grits to smooth surface.
Finishing Metal
Constantly move across the surface. Work faster on
curved surfaces where contact areas are smaller
and pressure is greater. Flat areas may appear at
the end of the stroke when pressure is too heavy.
Ease up on pressure at end of each stroke and
when reversing strokes.
MAINTENANCE
WARNING To reduce the risk of
injury, always unplug your tool before
performing any maintenance. Never disassemble the tool or try to do any rewiring
on the tool’s electrical system. Contact a
MILWAUKEE service facility for ALL repairs.
Maintaining Tools
Keep your tool in good repair by adopting a regular
maintenance program. Before use, examine the
general condition of your tool. Inspect guards,
switches, tool cord set and extension cord for
damage. Check for loose screws, misalignment,
binding of moving parts, improper mounting, broken parts and any other condition that may affect
its safe operation. If abnormal noise or vibration
occurs, turn the tool off immediately and have the
problem corrected before further use. Do not use a
damaged tool. T ag damaged tools "DO NOT USE"
until repaired (see "Repairs").
Under normal conditions, relubrication is not necessary until the motor brushes need to be replaced.
After six months to one year, depending on use,
return your tool to the nearest MILWAUKEE service
facility for the following:
• Lubrication
• Brush inspection and replacement
• Mechanical inspection and cleaning (gears,
spindles, bearings, housing, etc.)
• Electrical inspection (switch, cord, armature, etc.)
• T esting to assure proper mechanical and electrical operation
Troubleshooting
Deep scratches and circular marks can result
from:
• Using too coarse a grit
• Using a partially glazed disc
• Dirt or loose metal on the workpiece
• Failure to sand across the grain when changing
from coarse to fi nishing discs
• Failure to use closed coated discs to reduce
the problem of grains working loose and
scratching the workpiece
Bluish discoloration of metal surface indicates:
• Excessive heat caused by circular motion in a
small area
• Excessive pressure
• Use of worn out or glazed discs
WARNING T o reduce the risk of injury ,
electric shock and damage to the tool, never
immerse your tool in liquid or allow a liquid
to fl ow inside the tool.
Cleaning
Clean dust and debris from vents. Keep the tool
handles clean, dry and free of oil or grease. Use
only mild soap and a damp cloth to clean your tool
since certain cleaning agents and solvents are
harmful to plastics and other insulated parts. Some
of these include: gasoline, turpentine, lacquer thinner, paint thinner, chlorinated cleaning solvents,
ammonia and household detergents containing
ammonia. Never use fl ammable or combustible
solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the
nearest service center.
ACCESSORIES
WARNING T o reduce the risk of injury ,
always unplug the tool before attaching or
removing accessories. Use only specifi cally
recommended accessories. Others may be
hazardous.

RÈGLES DE SÉCURITÉ GÉNÉRALES RELATIVES AUX
OUTILS ÉLECTRIQUES
AVERTISSEMENT
LIRE TOUTES LES RÈGLES ET INSTRUCTIONS DE SÉCURITÉ.
Ne pas suivre l’ensemble des règles et instructions peut entraîner une électrocution, un
incendie ou des blessures graves.
Conserver les règles et les instructions à des fi ns de référence ultérieure.
Le terme «outil électrique» fi gurant dans les avertissements ci-dessous renvoie à l’outil élec-
trique à alimentation par le réseau (à cordon) ou par batterie (sans fi l).
SÉCURITÉ DU LIEU DE TRA VAIL
• Maintenir la zone de travail propre et bien
éclairée. Les zones encombrées ou mal éclairées
sont favorables aux accidents.
• Ne pas utiliser d’outil électrique dans une atmosphère explosive, telle qu’en en présence
de liquides, de gaz ou de poussières infl am-
mables. Les outils électriques génèrent des
étincelles qui peuvent enfl ammer les poussières
ou les fumées.
• Tenir les enfants et les personnes non autorisées à l’écart pendant le fonctionnement
d’un outil électrique. Un manque d’attention de
l’opérateur risque de lui faire perdre le contrôle
de l’outil.
SÉCURITÉ ÉLECTRIQUE
• La fi che de l’outil électrique doit correspondre
à la prise d’alimentation. Ne jamais modifi er
la fi che d’une manière quelconque. Ne pas
utiliser d’adaptateur avec les outils électriques
mis à la terre (à la masse). Des fi ches non
modifi ées et des prises d’alimentation assorties
réduisent le risque de choc électrique.
• Éviter tout contact corporel avec des surfaces
reliées à la masse ou à la terre telles que tuyaux, radiateurs, cuisinières et réfrigérateurs.
Un risque de choc électrique plus élevé existe si
le corps est relié à la masse ou à la terre.
• Ne pas exposer les outils électriques à la pluie
ou à l’humidité. Le risque de choc électrique
augmente si de l’eau s’infi ltre dans un outil élec-
trique.
• Prendre soin du cordon. Ne jamais utiliser le
cordon pour transporter, tirer ou débrancher
l’outil électrique. Tenir le cordon à l’écart de la
chaleur, des huiles, des arêtes coupantes ou
des pièces en mouvement. Un cordon endom-
magé ou emmêlé présente un risque accru de
choc électrique.
• Se procurer un cordon d’alimentation approprié en cas d’utilisation d’un outil électrique à
l’extérieur. L’utilisation d’un cordon d’alimentation
pour usage extérieur réduit le risque de choc
électrique.
• S’il est nécessaire d’utiliser l’outil électrique
dans un endroit humide, installer un appareil
à courant résiduel (RCD). L’utilisation d’un RCD
réduit le risque de décharge électrique.
SÉCURITÉ INDIVIDUELLE
• Être sur ses gardes, être attentif et faire preuve
de bon sens en utilisant un outil électrique. Ne
pas utiliser un outil électrique en cas de fatigue ou sous l’infl uence de drogues, d’alcool
ou de médicaments. Un instant d’inattention lors
de l’utilisation d’un outil électrique peut entraîner
des blessures graves.
• Porter l’équipement de protection requis.
Toujours porter une protection oculaire.
Selon les conditions, porter aussi un masque
anti-poussières, des bottes de sécurité antidérapantes, un casque protecteur ou une protection
auditive afi n de réduire les blessures.
• Empêcher les démarrages accidentels.
S’assurer que la gâchette est en position
d’arrêt avant de brancher l’outil à une source
de courant, d’insérer la batterie, de le ramasser ou de le transporter. Le fait de transporter
l’outil en gardant le doigt sur la gâchette ou de le
brancher lorsque la gâchette est en position de
marche favorise les accidents.
• Retirer toute clé de réglage avant de mettre
l’outil sous tension. Une clé laissée attachée
sur une pièce mobile de l’outil électrique peut
entraîner des blessures.
• Ne pas travailler à bout de bras. Bien garder
un bon équilibre à tout instant. Ceci permet de
mieux préserver la maîtrise de l’outil électrique
dans des situations imprévues.
• Porter des vêtements adéquats. Ne pas porter
de vêtements amples ni de bijoux. Ne pas approcher les cheveux, vêtements et gants des
pièces en mouvement. Les vêtements amples,
les bijoux ou les cheveux longs risquent d’être
happés par les pièces en mouvement.
• Si des dispositifs sont prévus pour l’extraction
et la récupération des poussières, vérifi er
qu’ils sont connectés et utilisés correctement.
L’utilisation de ces dispositifs peut réduire les
risques liés aux poussières.
UTILISATION ET ENTRETIEN
DE L’OUTIL ÉLECTRIQUE
• Ne pas forcer l’outil électrique. Utiliser l’outil
