WARNING: Read all safety warnings, instructions, illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTURE REFERENCE.
The term “power tool” in the warnings refers to your mains­operated (corded) power tool or battery-operated (cordless) powertool.
1) Work Area Safety
a ) Keep work area clean and well lit. Cluttered or dark
areas inviteaccidents.
b ) Do not operate power tools in explosive
atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which
may ignite the dust orfumes.
c ) Keep children and bystanders away while operating
a power tool. Distractions can cause you to losecontrol.
2) Electrical Safety
a ) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools.

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.
d ) Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personalinjury.
e ) Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power tool in unexpectedsituations.
f ) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be
caught in movingparts.
g ) If devices are provided for the connection of dust
extraction and collection facilities, ensure these are connected and properly used. Use of dust collection
can reduce dust-relatedhazards.
h ) Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe
injury within a fraction of asecond.
4) Power Tool Use and Care
a ) Do not force the power tool. Use the correct power
tool for your application. The correct power tool
will do the job better and safer at the rate for which it wasdesigned.
b ) Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled with the switch is dangerous and must berepaired.
c ) Disconnect the plug from the power source and/
or the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive
safety measures reduce the risk of starting the power toolaccidentally.
d ) Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of
untrainedusers.

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 SPECIFIC SAFETY RULES
Safety Instructions for All Operations
Safety Warnings Common for Grinding, Sanding, Wire Brushing or Abrasive Cutting-Off Operations:
a ) This power tool is intended to function as a
grinder, sander, wire brush 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 ) Operations such as polishing are not recommended
to be performed with this power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury.
4
Page 7
c ) 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.
d ) 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.
e ) The outside diameter and the thickness of your
accessory must be within the capacity rating of your power tool. Incorrectly sized accessories can not be
adequately guarded or controlled.
f ) Threaded mounting of accessories must match
the grinder spindle thread. For accessories mounted by flanges, the arbour 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.
g ) Do not use a damaged accessory. Before each use
inspect the accessory such as abrasive wheel for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute. Damaged
accessories will normally break apart during this test time.
h ) Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments.
The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
i ) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear personal protective equipment. Fragments of
workpiece or of a broken accessory may fly away and cause injury beyond immediate area of operation.
j ) 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 could give the operator an electrical shock.
k ) Position the cord clear of the spinning accessory. I f
you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory.
ENGLISH
l ) 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.
m ) 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.
n ) 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.
o ) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
p ) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in electrocution or shock.
FURTHER SAFETY INSTRUCTIONS FOR ALL OPERATIONS
Causes and Operator Prevention of Kickback
Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel’s movement at the point of pinching. Abrasive wheels may also break under these conditions.
Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:
a ) Maintain a firm grip on the power tool and position
your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start up. The operator can control torque reaction
or kickback forces, if proper precautions are taken.
b ) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c ) Do not position your body in the area where power
tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the wheel’s movement at the point of snagging.
d ) Use special care when working corners, sharp edges
etc. Avoid bouncing and snagging the accessory.
Corners, sharp edges or bouncing have a tendency to
5
Page 8
ENGLISH
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 centre depressed wheels
must 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 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 operations, 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 cut­off 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 re-enter 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 ) 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 work and centrifugal forces.
Additional Safety Rules for Grinders
• 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.
• The grinding surface of the centre depressed wheels must 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.
Do not use Type 11 (flaring cup) wheels on this tool. Using inappropriate accessories can result in injury.
Always use side handle. Tighten the handle securely. The side handle should always be used to maintain control of the tool at all times.

• Be sure the inner and outer flange are mounted correctly. Follow the instructions given in the Grinding and Cutting
Accessory Chart.
• Make sure the disc or wheel rotates in the direction of the arrows on the accessory and thetool.
• 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.

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.
• Always wear regular working gloves while operating this tool.
• The gear becomes very hot during use.
• Apply only a gentle pressure to the tool. Do not exert side pressure on thedisc.
• Avoid overloading. Should the tool become hot, let it run a few minutes under no load condition.
• Avoid overloading. Should the tool become hot, let it run a few minutes under no load condition to cool the accessory. Do not touch accessories before they have cooled. The discs become very hot during use.
• Never work with the grinding cup without a suitable protection guard inplace.
• Do not use the power tool with a cut-off stand.
• Never use blotters together with bonded abrasive products.
• Be aware, the wheel continues to rotate after the tools is switched off.

WARNING: In extreme working conditions, conductive dust can accumulate inside the machine housing when
working with metal. This can result in the protective insulation in the machine becoming degraded with a potential risk of an electrical shock.
Cutting Metal
When cutting, work with moderate feed, adapted to the material being cut. Do not exert pressure onto the cutting disc, tilt or oscillate the machine.
Do not reduce the speed of running down cutting discs by applying sideward pressure.
The machine must always work in an upgrinding motion. Otherwise, the danger exists of it being pushed uncontrolled out of the cut.
When cutting profiles and square bar, it is best to start at the smallest cross section.

Never use a cutting disc for roughing. Always use the guard type 27.
The best roughing results are achieved when setting the machine at an angle of 30° to 40°. Move the machine back and forth with moderate pressure. In this manner, the workpiece will not become too hot, does not discolour and no grooves are formed.
Cutting Stone
The machine shall be used only for dry cutting. For cutting stone, it is best to use a diamond cutting disc. Operate the
machine only with additional dust protection mask.
Working Advice
Exercise caution when cutting slots in structural walls. Slots in structural walls are subject to the country-specific regulations. These regulations are to be observed under all circumstances.Before beginning work, consult the responsible structural engineer, architect or the construction supervisor.
