It can be prevented by taking the appropriate precautions as described below. a) Maintain a firm grip on the electrical power tool and position your body and arms to allow you to resist kickback forces. Always use the auxiliary handle, if provided, to exercise the greatest possible control over kickback forces or reaction torques as the device builds up to full speed. By taking 10 GB/IE III PARKSIDE General safety advice for electrical power tools suitable precautions the operator can control kickback and reaction forces. b) Do not place your hands near a rotating attachment. If kickback occurs the attachment could move over your hand. c) Avoid positioning your body in the area into which the electrical power tool would move in the event of a kickback. A kickback moves the electrical power tool in the opposite direction to the direction of movement of the grinding disc at the point of constraint. d) Work particularly carefully in the area of corners, sharp edges etc. to avoid the attachment bouncing or snagging on the workpiece. Corners, sharp edges or bouncing have a tendency to snag the rotating attachment. This causes loss of control or kickback. e) Do not use saw-chain woodcarving discs or toothed discs. Such attachments create frequent kickback and loss of control of the electrical power tool. • Special safety advice relating to grinding and disc-cutting a) Always use the guard designed for the type of abrasive consumable you are using. Always use abrasive consumables approved for use with your electrical power tool. Abrasive consumables not approved for use with your electrical power tool cannot be adequately guarded and are unsafe. b) To ensure the highest level of operational safety, the disc guard cover must be attached to the electrical power tool and set in such a way that the smallest possible area of the abrasive consumable is exposed to the operator. The disc guard cover is there to protect the operator from pieces breaking off and accidental contact with the abrasive consumable. c) Abrasive consumables must be used only for their recommended purposes, For example: never grind with the side face of a cutting disc. Cutting discs are intended for removing material using the edge of the disc. Sideways forces on these abrasive consumables can cause them to break. d) Always use an undamaged mounting flange of the correct size and shape for your selected grinding disc. Suitable flanges support the grinding disc and reduce the chance of it breaking. Flanges for cutting discs are different from the flanges for other abrasive discs. e) Never use worn down abrasive consumables intended for larger electrical power tools. Abrasive consumables intended for larger electrical power tools are not designed for the faster rotational speeds of these smaller electrical power tools and could break. • Further special safety advice for disc-cutting a) Avoid snagging the cutting disc and do not use too much contact pressure. Do not attempt to make excessively deep cuts. Overloading the cutting disc increases the load and the tendency of the disc to twist or snag in the cut, making kickback or disc breakage more likely. b) Avoid the area in front of or behind the rotating cutting disc. If the cutting disc is moving away from you at the point of constraint in the workpiece, then, in the event of a kickback, the electrical power tool and the rotating disc may be thrown towards you. c) If the cutting disc jams or you stop work for a while, switch the device off and hold it until the disc comes to a complete stop. Never attempt to pull the still rotating cutting disc out of the cut as this could cause kickback. Determine and rectify the reason for the jamming. d) Do not switch on the device if the cutting disc is in the workpiece. Allow the cutting disc to reach full speed before carefully continuing with the cut. Otherwise the disc could snag, jump out of the workpiece or cause a kickback. III PARKSIDE GB/IE 11 General safety advice for electrical power tools e) Support boards or workpieces whilst cutting to reduce the risk of kickback caused by a jammed cutting disc. Large workpieces may bend under their own weight. The workpiece must be supported to both sides of the cutting disc and particularly near the cutting disc and at the workpiece edge. f) Be particularly careful when pocket cutting in existing walls or other areas where you cannot see what you are cutting into. The cutting disc plunged into the surface could cut through gas or water pipes, electricity cables or other objects and cause kickback. • Special safety advice for abrading using sandpaper ■ Do not use over-sized sanding sheets. Follow the manufacturer's recommendations for sanding sheet size. Sanding sheets that project beyond the backing pad could cause injury in addition to jamming, tearing of the sheet or kickback. • Special safety advice for polishing ■ Do not use the polishing bonnet if it has any loose parts, in par...
