or binding of the wheel in the cut and the possibility of kickback or wheel breakage. b) Do not position your body in line with and behind the rotating wheel. When the wheel, at the point of operation, is moving away from your body, the possible kickback may propel the spinning wheel and the power tool directly at you. c) 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 complete 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 d) Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully reenter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece. e) Support panels or 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. f) 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. 21. Safety Warnings Specific for Sanding Operations: a) Do not use excessively oversized sanding disc paper. Follow manufacturers recommendations, when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc or kickback. 22. Safety Warnings Specific for Wire Brushing Operations: a) 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. b) If the use of a guard is recommended for wire brushing, do not allow 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. 23. When using depressed center grinding wheels, be sure to use only fiberglass-reinforced wheels. 24. Be careful not to damage the spindle, the flange (especially the installing surface) or the lock nut. Damage to these parts could result in wheel breakage. 25. Make sure the wheel is not contacting the workpiece before the switch is turned on. 26. Before using the tool on an actual workpiece, let it run for a while. Watch for vibration or wobbling that could indicate poor installation or a poorly balanced wheel. 27. Use the specified surface of the wheel to perform the grinding. 28. Watch out for flying sparks. Hold the tool so that sparks fly away from you and other persons or flammable materials. 29. Do not leave the tool running. Operate the tool only when hand-held. 30. Do not touch the workpiece immediately after operation; it may be extremely hot and could burn your skin. 31. Always be sure that the tool is switched off and unplugged or that the battery cartridge is removed before carrying out any work on the tool. 32. Observe the instructions of the manufacturer for correct mounting and use of wheels. Handle and store wheels with care. 33. Do not use separate reducing bushings or adaptors to adapt large hole abrasive wheels. 34. Use only flanges specified for this tool. 35. For tools intended to be fitted with threaded hole wheel, ensure that the thread in the wheel is long enough to accept the spindle length. 36. Check that the workpiece is properly supported. 37. Pay attention that the wheel continues to rotate after the tool is switched off. 38. If working place is extremely hot and humid, or badly polluted by conductive dust, use a short-circuit breaker (30 mA) to assure operator safety. 39. Do not use the tool on any materials containing asbestos. 40. Do not use water or grinding lubricant. 41. Ensure that ventilation openings are kept clear when working in dusty conditions. If it should become necessary to clear dust, first disconnect the tool from the mains supply ( use non metallic objects ) and avoid damaging internal parts. 42. When use cut-off wheel, always work with the dust collecting wheel guard required by domestic regulation. 43. Cutting discs must not be subjected to any lateral pressure. 6
