Safety warnings specific for wire brushing operations: 1. 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. 2. If the use of a guard is specified 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. Additional Safety Warnings: 1. When using depressed centre grinding wheels, be sure to use only fiberglass-reinforced wheels. 2. NEVER USE Stone Cup type wheels with this grinder. This grinder is not designed for these types of wheels and the use of such a product may result in serious personal injury. 3. 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. 4. Make sure the wheel is not contacting the workpiece before the switch is turned on. 5. 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. 6. Use the specified surface of the wheel to perform the grinding. 7. Do not leave the tool running. Operate the tool only when hand-held. 8. Do not touch the workpiece immediately after operation; it may be extremely hot and could burn your skin. 9. Do not touch accessories immediately after operation; it may be extremely hot and could burn your skin. 10. Observe the instructions of the manufacturer for correct mounting and use of wheels. Handle and store wheels with care. 11. Do not use separate reducing bushings or adaptors to adapt large hole abrasive wheels. 12. Use only flanges specified for this tool. 13. 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. 14. Check that the workpiece is properly supported. 15. Pay attention that the wheel continues to rotate after the tool is switched off. 16. 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. 17. Do not use the tool on any materials containing asbestos. 18. When use cut-off wheel, always work with the dust collecting wheel guard if required by domestic regulation. 19. Cutting discs must not be subjected to any lateral pressure. 20. Do not use cloth work gloves during operation. Fibers from cloth gloves may enter the tool, which causes tool breakage. 21. Before operation, make sure that there is no buried object such as electric pipe, water pipe or gas pipe in the workpiece. Otherwise, it may cause an electric shock, electrical leakage or gas leak. 22. If a blotter is attached to the wheel, do not remove it. The diameter of the blotter must be larger than the lock nut, outer flange, and inner flange. 23. Before installing a grinding wheel, always check that the blotter part does not have any abnormalities such as chips or cracks. 24. Tighten the lock nut properly. Overtightening the wheel can cause breakage and insufficient tightening can cause fluttering. SAVE THESE INSTRUCTIONS.
