4.1 Safety instructions when grinding with

cup wheels: a) This power tool is intended to function as a grinder. 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, sanding, wire brushing or cutting-off 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. 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 external diameter and thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot 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 wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If a 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. Use a face shield, safety goggles or safety goggles depending on the application. As appropriate, wear a dust mask, hearing protectors, gloves and a 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 filtering 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 a workpiece or broken accessory may fly away and cause injury beyond the immediate area of operation. j) When carrying out tasks that involve a risk of the mounted tool contacting hidden wiring, make sure you hold the device on the insulated gripping surfaces only. A cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock. k) Position the cord clear of the rotating accessory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the rotating accessory.

I) Never lay the power tool down until the

accessory has come to a complete stop. The rotating accessory may grab the surface and pull the power tool out of your control.

1. Declaration of Conformity

2. Specified Conditions of Use

m) Do not run the power tool while carrying it at your side. Accidental contact with the rotating 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.

4.2 Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or snagged grinding 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 abrasive wheel may either jump toward or away from the operator, depending on direction of the disc’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 if suitable precautionary measures are taken as described 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 reactions 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 the power tool will move if kickback occurs. Kickback will propel the tool in direction opposite to the grinding 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 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.

4.3 Safety Warnings Specific for Grinding

and Cut-Off Grinding: 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 the centre depressed wheels must be mounted below the plane of the guard lip. An improperly mounted grinding 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 operator from broken wheel fragments and accidental contact with wheel and sparks which could ignite clothing. d) Grinding media must be used only for recommended applications. For example: Do not grind with the side of cutting disc. Cutting discs 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 grinding wheel. Proper wheel flanges support the grinding wheel thus reducing the possibility of grinding wheel breakage. Flanges for cutting discs may be different from grinding wheel flanges. f) Do not use worn down grinding wheels from larger power tools. Grinding wheels intended for larger power tools are not suitable for the higher speed of a smaller tool and may break.

4.4 Additional safety instructions:

WARNING – Always wear protective goggles. Check the isolation of the handle for damage prior to use. Do not use any damaged side handles! Use elastic cushioning layers if they have been supplied with the sanding media and if required. Observe the specifications of the tool or accessory manufacturer! Protect the discs from grease or impact! Cup wheels must be stored and handled with care in accordance with the manufacturer's instructions. Do not use machines with cutting or grinding discs. The workpiece must lay flat and be secured against slipping, e.g. using clamps. Large workpieces must be sufficiently supported. If accessories with threaded inserts are used, the end of the spindle may not touch the base of the hole on the sanding tool. Make sure that the thread in the accessory is long enough to accommodate the full length of the spindle. The thread in the accessory must match the thread on the spindle. See page 2 and chapter 15. Technical Specifications for more information on the spindle length and thread.ENGLISHen

When working in dusty conditions, ensure that ventilation openings are not blocked. If it becomes necessary to remove dust, first remove the battery pack (use non-metallic objects) and avoid damaging internal components. Damaged, eccentric or vibrating tools must not be used. Avoid damage to gas or water pipes, electrical cables and load-bearing walls (static). Remove the battery pack from the machine before making any adjustments, changing tools, maintaining or cleaning. Make sure that the tool is switched off before fitting the battery pack. A damaged or cracked additional handle must be replaced. Never operate the machine with a defective additional handle. A damaged or cracked safety guard must be replaced. Never operate a machine with a defective safety guard. Secure small workpieces. For example, clamp in a vice. Reducing dust exposure: Some of the dust created using this power tool may contain chemicals known to cause cancer, allergic reaction, respiratory disease, birth defects or other reproductive harm. Some of these substances include: lead (in paint containing lead), mineral dust (from bricks, concrete etc.), additives used for wood treatment (chromate, wood preservatives), some wood types (such as oak or beech dust), metals, asbestos. The risk from exposure to such substances will depend on how long the user or nearby persons are being exposed. Do not let particles enter the body. To reduce exposure to these substances: work in a well ventilated area and wear protective equipment, such as dust masks that are specially designed to filter out microscopic particles. Observe the relevant guidelines for your material, staff, application and place of application (e.g. occupational health and safety regulations, disposal). Collect the particles generated at the source, avoid deposits in the surrounding area. Use suitable accessories for special work (see

chapter 12.), thus less particles enter the

environment in an uncontrolled manner. Use a suitable extraction unit. Reduce dust exposure with the following measures: - do not direct the escaping particles and the exhaust air stream at yourself or nearby persons or on dust deposits. - use an extraction unit and/or air purifiers. - ensure good ventilation of the workplace and keep clean using a vacuum cleaner. Sweeping or blowing stirs up dust. - Vacuum or wash the protective clothing. Do not blow, beat or brush.
