Safety instructions for all operations

Safety warnings common for grinding

WARNING!

Read all safety instructions and other instructions. Failure to observe the safety instructions and other instructions may result in an electric shock, fire and/or serious injuries. Keep all safety instructions and other instructions in a safe place for the future.

■ This power tool is intended to function as a sander. 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 sanding, wire brushing, polishing, hole cutting or cutting-off are not 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 convert this power tool to operate in a way which is not specifically designed and specified by the tool manufacturer. Such a conversion may result in a loss of control and cause serious personal injury.
- Do not use accessories which are not specifically designed and specified 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 measured insertion tools cannot be adequately shielded or controlled.
■ The dimensions of the accessory mounting must fit the dimensions of the mounting hardware of the power tool. 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 use, always check insertion tools for splinters and cracks, sanding pad for cracks, wear and severe abrasion. 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. If appropriate, wear a dust mask, hearing protection, protective gloves and/or a special apron which protect you from small sanding and material particles. 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.

- 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 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.

Further safety instructions for all operations

Kickback and Related Warnings Kickback is the sudden reaction to a pinched or snagged rotating insertion tool, such as a sanding disc, sanding pad, wire brush, etc. Pinching or snagging may cause a rotating insertion tool to stop abruptly. 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 kick-back 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 propels the electric power tool in the direction opposite to the movement of the sanding disc at the point of pinching.
■ 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. This causes a 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.

Additional safety instructions for grinding and cutting-off operations

Safety warnings specific for grinding and cutting-off operations

■ Use only wheel types that are specified 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 center 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 maxi - mum 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 specified applications. For example: do not grind with the side of cut-off wheelAbrasive 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. A wheel intended for larger power tool is not suitable for the higher speed of a smaller tool and may burst.
■ When using dual purpose wheels always use the correct guard for the application being performed. Failure to use the correct guard may not provide the desired level of guarding, which could lead to serious injury.

Additional safety instructions

■ Use only extension cables permitted for outdoor use.
■ It is not recommended to sand lead paint. Lead paint should be removed by a specialist only.
■ Do not work on materials which release hazardous substances (e.g. asbestos). Take precautions if hazardous, combustible or explosive dust is likely to occur. Wear protective dust mask. Use dust extraction system.

DAMAGE TO PROPERTY!

The mains voltage and the voltage specifications on the rating plate must correspond.

Noise and vibration

NOTE

Values for the A-weighted sound pressure level and for the total vibration values can be found in the “Technical specifications” table.

The noise and vibration values have been determined in accordance with EN 62841.

WARNING!

The indicated measurements refer to new power tools. Daily use causes the noise and vibration values to change.

NOTE

The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 62841 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure. The declared vibration emission level represents the main applications of the tool.

However if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.

For a precise estimation of the vibrationload the times should also be considered during which the power tool is switched off or even running, but not actually in use.

This may significantly decrease the exposure level over the total working period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

CAUTION!

Wear ear protection at a sound pressure above 85 dB(A).
