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. Refer to the table below. Accessory ratings are above rated no-load tool speeds because actual tool speeds may vary. NOTE: The rated no load tool speed is printed on the name plate and embossed on the gear case. Rated no (no load) Tool Speed Minimum Accessory Rating 5000 RPM 5500 RPM 6000 RPM 6600 RPM 8000 RPM 8500 RPM 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. Clean out your tool often, especially after heavy use. Dust and grit containing metal particles often accumulate on interior surfaces and could create a risk of serious injury, electric shock or electrocution. Before using, inspect recommended accessory for cracks or flaws. If such a crack or flaw is evident, discard the accessory. The accessory should also be inspected whenever you think the tool may have been dropped. When starting the tool with a new or replacement wheel, or a new or replacement wire brush installed, hold the tool in a well protected area and let it run for one minute. If the wheel has an undetected crack or flaw, it should burst in less than one minute. If the wire brush has loose wires, they will be detected. Never start the tool with a person in line with the wheel. This includes the operator. In operation, avoid bouncing the wheel or giving it rough treatment. If this occurs, stop the tool and inspect the wheel for cracks and flaws. Direct sparks away from operator, bystanders or flammable materials. Sparks may be produced while using a sander or grinder. Sparks may cause burns or start fires. Always use side handle. Tighten the handle securely. The side handle should always be used to maintain control of the tool at all times. Use extra care when grinding into a corner because a sudden, sharp movement of the grinder may be experienced when the wheel contacts a secondary surface. Wear appropriate personal hearing protection during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects, or other reproductive harm. Some examples of these chemicals are: • lead from lead-based paints, • crystalline silica from bricks and cement and other masonry products, and • arsenic and chromium from chemically-treated lumber (CCA). 3
