en ENGLISH placed on a combustible surface such as wood. Sparks could ignite these materials. n) 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 rotating wheel. Pinching or snagging causes rapid stalling of the rotating wheel which in turn causes the uncontrolled cutting unit to be forced upwards toward the operator. 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. 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. a) Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. The operator can control upward kickback forces, if proper precautions are taken. b) Do not position your body in line with the rotating wheel. If kickback occurs, it will propel the cutting unit upwards toward the operator. c) Do not attach a saw chain, woodcarving blade, segmented diamond wheel with a peripheral gap greater than 10 mm or toothed saw blade. Such blades create frequent kickback and loss of control. d) Do not „jam" the 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. e) When the wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold the cutting unit motionless until the wheel comes to a complete stop. Never attempt to remove the 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. f) 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. g) Support 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. helmet and apron. When judging if face or dust masks are necessary, take into consideration whether the workpiece to be machined or its coating are potentially harmful to health. Put on protective clothing in case of doubt. Wear ear protectors when working for long periods of time. High noise levels over a prolonged period of time may affect your hearing. Do not work with magnesium. Do not use power tools in a damp or wet environment. Do not use the machine in environments where there is the risk of explosion, in which sparks can cause fire, explosions or the like. Do not use saw blades. Always ensure the metal cut-off machine is stable on a flat surface; when using the cut-off machine on a workbench, always attach the metal cut-off machine with appropriately long, sturdy screws. Danger of crushing! Do not reach into the area of the joint when lowering the lever! Never operate the machine without a protective hood (7). Always tilt protective hood (7) all the way down. Be sure that the movable protective hood (7) is not jammed. It must be able to move. Check the power tool for potential damage. -Before continuing to use the power tool, protective mechanisms or lightly damaged parts must be carefully inspected for correct operation. -Damaged protective mechanisms and parts must be repaired or replaced by an approved specialist workshop, as long as nothing else is specified in the instruction manual. Machine malfunctions, incl. protective hoods or cutting discs, must immediately be reported when they occur. The malfunction must be properly remedied. Regularly check the connection lead of the power tool and have it repaired by an approved expert, should it be damaged. Regularly check extension cables and replace them, should they be damaged. Use only three-conductor cables. Keep the handles dry, clean and free of oil and grease. Do not use a low-power machine for demanding jobs. Adhere to the instructions for lubrication and tool replacement. Store the machine in a dry, high or secured place, outside the reach of children. 4.3 12 Additional Safety Instructions Always wear eye protection and hearing protection. Put on other protective gear if necessary, such as dust masks, gloves, When working in dusty conditions, ensure that ventilation openings are not blocked. Should it be necessary to remove the dust, first disconnect the power tool from the mains.
