Intended use of the power tool

Hand-guided angle grinder for dry grinding, wire brushing and cutting of metal and stone as well as for cutting tiles in weather-protected environments without the use of liquid coolants, using the application tools and accessories recommended by FEIN.
In environments subject to interference, a reduction of the operating quality is possible; this can include temporary failure, temporary reduction of the function or the intended operating behaviour, for the correction of which intervention by the operator is required.
This power tool is also suitable for use with AC generators with sufficient power output that correspond to the Standard ISO 8528, design type G2. This Standard is particularly not complied with when the so-called distortion factor exceeds 10 %. When in doubt, please refer to the generator instruction/specification guide. Observe the operating instructions and the national regulations for the installation and operation of the AC generator.
The power tool is not intended for working light metals and for polishing. The operator is solely liable for any damage caused by use not as intended for.
Generally recognized accident prevention regulations and enclosed safety instructions must be observed.
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 specifications pro-vided 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 acces-sory 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 bystand-ers 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 testtime.
• Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing pro-tectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye pro-tection must be capable of stopping flying debris gener-ated 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 pro-tective equipment. Fragments of workpiece or of a bro-ken accessory may fly away and cause injury beyond immediate area of operation.
• Hold the power tool by insulated gripping surfaces only, when performing an operation where the cutting acces-sory 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.
• 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 materi-als. Sparks could ignite these materials.
• Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in elec-trocution or shock.

Kickback and related warnings

• Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other acces-sory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncon-trolledpower tool to be forced in the direction oppo-site 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 oper-ator, 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 kick-back 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. Cor-ners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kick-back.
• Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kick-back and loss of control.
• Safety warnings specific for grinding and abra-sive 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 operator from broken wheel fragments, accidental contact with wheel and sparks that could ignite clothing.
• Wheels must be used only for recommended applica-tions. For example: do not grind with the side of cut-off wheel. Abrasive cut-off wheels are intended for periph-eral grinding; side forces applied to these wheels may cause them to shatter.
• Always use undamaged wheel flanges that are of cor-rect size and shape for your selected wheel. Proper wheel flanges support the wheel thus reducing the pos-sibility 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 pres-sure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and sus-ceptibility 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 oper-ation, 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 com-plete 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 work-pieces 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 select-ing 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 oper-ations
• 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.

Further safety warnings

• Do not wear easily flammable clothing. Sparks could cause such clothing to ignite.
• Use elastic spacers/liners when these are provided with the grinding accessory.
• Offset grinding discs must be mounted in such a manner that their grinding surface is 2 mm below the bottom edge the of the wheel guard. Grinding accessories that do not meet these requirements cannot be adequately covered off and are not permitted.
• Make sure that the application tools are mounted in accordance with the manufacturers instructions. The mounted application tools must be able to rotate freely. Incorrectly mounted application tools can become loose during operation and be thrown from the machine.
• Handle grinding accessories carefully and store them according to the manufacturer’s instructions. Damaged grinding accessories can develop cracks and burst during operation.
• When using application tools with a threaded insert, take care that the thread in the application tool is long enough to hold the spindle length of the power tool. The thread in the application tool must match the thread on the spindle. Incorrectly mounted application tools can loosen during operation and cause injuries.
• Do not direct the power tool against yourself, other persons or animals. Danger of injury from sharp or hot application tools.
• Beware of any concealed electric cables, gas or water conduits. Check the working area before commencing work, e. g. with a metal detector.
• Use a stationary extraction system and frequently blow out the ventilation slots. When working metal under extreme operating conditions, it is possible for conductive dust to settle in the interior of the power tool. The total insulation of the power tool can be impaired.
• Do not rivet or screw any name-plates or signs onto the power tool. If the insulation is damaged, protection against an electric shock will be ineffective.
• Always work with the auxiliary handle. The auxiliary handle ensures reliable guiding of the power tool.
• Never look or stare into the light of the power tool’s lamp from a short distance. Never point the light of the lamp into the eyes of other persons in close vicinity. The radiation produced by the lamp can be harmful for the eye.
• After working gypsum-containing materials: Blow out the ventilation openings of the power tool and the switch element with dry and oil-free compressed air. Otherwise, gypsum-containing dust can settle in the power tool housing and switch element, which can harden in connection with humidity. This can impair the switching mechanism.

Hand/arm vibrations
The vibration emission level given in this information sheet has been measured in accordance with a stand-ardised test given in EN 60745 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 accesso-ries or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the expo-sure level over the total working period.
Identify additional safety measures to protect the oper-ator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organi-sation of work patterns.

Handling hazardous dusts
For work procedures with this power tool where material is removed, dusts develop that can be hazard-ous to one’s health.
Contact with or inhaling some dust types, e. g. asbestos and asbestos- containing materials, lead-containing coat-ings, metal, some wood types, minerals, silicate parti-cles from materials containing stone, paint solvents, wood preservatives, antifouling paints for vessels, can trigger allergic reactions to the operator or bystanders and/or lead to respiratory infections, cancer, birth defects or other reproductive harm. The risk from inhaling dusts depends on the exposition. Use dust extraction matched appropriately for the developing dust, as well as personal protective equipment and pro-vide for good ventilation of the workplace. Leave the processing of asbestos-containing materials to special-ists.
Wood and light-metal dust, hot mixtures of grinding dust and chemical materials can self-ignite under unfa-vourable conditions or cause an explosion. Avoid sparking in the direction of the dust collector as well as overheating of the power tool and the materials being sanded, empty the dust collector/container in time, observe the material manufacturer’s working instruc-tions, as well as the relevant regulations in your country for the materials being worked.
