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 mains-operated (corded) power tool or battery-operated

(cordless) power tool.

Work area safety

▶ Keep work area clean and well lit. Cluttered or dark areas invite accidents.

Printed: 29.08.2019 | Doc-Nr: PUB / 5476800 / 000 / 02

*2223269*

2223269 English 3

▶ 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.

▶ 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. Unmodified 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 electric shock if your body is earthed or grounded.

▶ Do not expose power tools to rain or wet conditions. Water 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 influence of drugs, alcohol or medication. 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 a

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 finger 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, jewellery 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 dust collection can reduce dust-related hazards.

▶ 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.

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 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.

▶ 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 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.

▶ 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.

*2223269*

▶ 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.

Battery tool use and care

▶ Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type

of battery pack may create a risk of fire when used with another battery pack.

▶ Use power tools only with specifically designated battery packs. Use of any other battery packs may

create a risk of injury and fire.

▶ When battery pack is not in use, keep it away from other metal objects, like paper clips, coins,

keys, nails, screws or other small metal objects, that can make a connection from one terminal to

another. Shorting the battery terminals together may cause burns or a fire.

▶ Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact

accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid

ejected from the battery may cause irritation or burns.

▶ Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may

exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.

▶ Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature

above 130° C (265 °F) may cause explosion.

▶ Follow all charging instructions and do not charge the battery pack or tool outside the temperature

range specified in the instructions. Charging improperly or at temperatures outside the specified range

may damage the battery and increase the risk of fire.

Service

▶ 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.

▶ Never service damaged battery packs. Service of battery packs should only be performed by the

manufacturer or authorized service providers.

2.1.2 Safety warnings common for grinding, sanding, wire brushing, polishing 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 specifications provided with this power tool. Failure

to follow all instructions listed below may result in electric shock, fire and/or serious injury.

▶ 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.

▶ 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.

▶ 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.

▶ 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.

▶ 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.

▶ 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. 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.

▶ 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.

*2223269*

2223269 English 5

▶ Hold the power tool by insulated gripping surfaces only, when performing an operation where the

cutting tool may contact hidden wiring. Contact with a "live" wire will also make exposed metal parts

of the power tool "live" and could give the operator an electric shock.

▶ 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.

▶ 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.

▶ 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 flammable 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 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 reactions or kickback forces, if proper

precautions are taken.

▶ Never place your hand near the rotating accessory. Accessory may kickback over your hand.

▶ 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.

▶ 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 specific guard designed

for the selected wheel. Wheels for which the power tool was not designed cannot be adequately

guarded and are unsafe.

▶ 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.

▶ 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.

▶ 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 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.

▶ 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:

▶ 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.

Printed: 29.08.2019 | Doc-Nr: PUB / 5476800 / 000 / 02

6 English 2223269

*2223269*

▶ 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 corrective 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

re-enter 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 "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:

▶ 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 specific for wire brushing operations:

▶ 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.

▶ 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 load and

centrifugal forces.

2.1.3 Additional safety instructions

Personal safety

▶ Only use the product if it is in perfect working order.

▶ Never tamper with or modify the tool in any way.

▶ Avoid touching rotating parts – risk of injury!

▶ Wear protective gloves also when changing the accessory tool. Touching the accessory tool presents a

risk of injury (cuts or burns).

▶ Before starting work, check the hazard class of the dust that will be produced when working. Use

an industrial vacuum cleaner with an officially approved protection class in compliance with the locally

applicable dust protection regulations. Dust from materials such as lead-based paint, certain types of

wood and concrete/masonry/stone containing quartz, minerals or metal may be harmful to health.

▶ Make sure that the workplace is well ventilated and, where necessary, wear a respirator appropriate for

the type of dust generated. Contact with or inhalation of the dust may cause allergic reactions and/or

respiratory or other diseases among operators or bystanders. Certain kinds of dust are classified as

carcinogenic such as oak and beech dust, especially in conjunction with additives for wood conditioning

(chromate, wood preservative). Material containing asbestos may be handled only by specialists.

▶ Take breaks between working and do physical exercises to improve the blood circulation in your fingers.

Exposure to vibration during long periods of work can lead to disorders of the blood vessels and nervous

system in the fingers, hands and wrists.

Electrical safety

▶ Before beginning work, check the working area for concealed electric cables or gas and water pipes.

External metal parts of the power tool may give you an electric shock if you damage an electric cable

accidentally.

Using and handling power tools with care

▶ Do not use cutting discs for grinding.

▶ Tighten the accessory tool and flange securely. If the accessory tool and flange are not tightened

securely, the accessory tool may work loose from the spindle due to the braking effect of the motor after

switching off.
