16. Do not overtighten the clamp nut on the grinding wheel. Excessive tightening can cause the wheel to crack during operation. 17. Make sure that the guard is in good condition and securely installed before operating grinder. 18. Do not clamp the grinder in a vise or use as a fixed grinder. 19. Never turn on the grinder with the grinding wheel or any rotating parts touching the workpiece. 20. Use only grinding wheels in compliance with ANSI standard B7.1 and rated greater than 11,000 RPM. 21. Do not use the grinder if the disc flange or clamp nut is missing or if the spindle is bent. General Power Tool Safety Warnings Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. WORK AREA SAFETY Keep work area clean and well lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control. Do not operate the power tool near flammable materials. Sparks could ignite these materials. ELECTRICAL SAFETY Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. If operat ing a power tool in a damp location is unavoidable, use a residual current device (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock. 1. Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock. 2. Do not operate tool with damaged cord or plug. • Have a damaged or worn power cord and/or strain relief replaced immediately. • Do not attempt to repair power cord. 3. Make sure cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress. 4. Do not use an extension cord unless absolutely necessary. Use of improper extension cord could result in a risk of fire and electric shock. If an extension cord must be used, make sure: DG470500CK NOTAS 2 27 Sp DG470500CK DG470500CK 26 Sp 3 Funcionamiento (Continuacion) alcancen la maxima velocidad. Baje gradualmente la rectificadora hasta que la rueda abrasiva entre en contacto con la pieza de trabajo. Para obtener mejores resultados mantenga la rectificadora inclinada a un angulo entre 5 y 15 grados y muevala constantemente a un ritmo parejo (ver Figuras 5 y 6). Mueva la rectificadora para adelante y atras o arriba y abajo en el area de trabajo. Mantenga la rectificadora en movimiento para no eliminar una cantidad excesiva de material de una misma area. Si mantiene la rectificadora en un punto durante mucho tiempo, cortara y hara ranuras en la pieza. Si la rectificadora se mantiene en un angulo demasiado agudo, tambien hara ranuras en la pieza de trabajo debido a la concentracion de la presion en una pequena area. Utilice apenas la presion suficiente para evitar que la rectificadora vibre o rebote. Demasiada presion disminuira la velocidad y forzara el motor. Normalmente, solo el peso de la herramienta alcanza para la mayoria de los trabajos de rectificado. Utilice poca presion cuando rectifique bordes mellados o pernos flojos donde existe la posibilidad de que la rectificadora se enganche en un borde de metal. Aleje la rectificadora de la pieza antes de apagarla. 5° - 15° Figura 5 - Angulo correcto 30°+ Figura 6 - Angulo incorrecto En las operaciones normales de cepillado con alambre, el material eliminado y las cerdas del cepillo se dispararan (hasta 50 pies o mas) con una fuerza considerable. Existe la posibilidad de que ocurran lesiones graves. Para protegerse contra este riesgo, los operadores y demas personas en el area de trabajo deben usar vestimenta de proteccion y gafas de seguridad, o protectores para todo el rostro sobre las gafas de seguridad con proteccion lateral. ...
