Resumen del manual
Service or maintenance performed by unqualified personnel could result in a risk of injury. 24.,When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock or injury. USBOOS-l Specific Safety Rules 1. Always use proper guard with grinding wheel. A guard protects operator from broken wheel fragments. 2. Accessories must be rated for at least the speed recommended on the tool warning label. Wheels and other accessories running over rated speed can fly apart and cause injury. 3.Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator. 4. Keep guards in place. 5. Use only wheels having a maximum operating speed at least as high as "No Load RPM" marked on the tool's nameplate. When using depressed center wheels, be sure to use only fiberglass-reinforced wheels. 6.Check the wheel carefully for cracks or damage before operation. Replace cracked or damaged wheel immediately. 7. Use only flanges specified for this tool. 8. 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. 9. Hold the tool firmly. IO.Keep hands away from rotating parts. 11. Make sure the wheel is not contacting the workpiece before the switch is turned on. 12.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. 13.Use the specified surface of the wheel to perform the grinding. 14. Watch out for flying sparks. Hold the tool so that sparks fly away from you and other persons or flammable materials. 15. Do not leave the tool running. Operate the tool only when hand-held. 16.Do not touch the workpiece immediately after operation; it may be extremely hot and could burn your skin. SAVE THESE INSTRUCTIONS.
