User manual DEWALT DW511

[. . . ] Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury, · dress properly. Keep your hair, clothing, and gloves away from moving parts. [. . . ] Double insulation eliminates the need for the three wire grounded power cord and grounded power supply system. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded. ⷠDon't expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. When operating a power tool outside, use an outdoor extension cord marked "W-A" or "W. " These cords are rated for outdoor use and reduce the risk of electric shock. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on cord length and nameplate ampere rating. CAUTION: Wear appropriate personal hearing protection during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss. CAUTION: DO NOT TOUCH ANY METAL PARTS OF THE TOOL when drilling or driving into walls, floors or wherever live electrical wires may be encountered!Hold the tool only by insulated grasping surfaces to prevent electric shock if you drill or drive into a live wire. ⷠThe label on your tool may include the following symbols. Reciprocations per min 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). Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. ⷠAvoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. [. . . ] IF DRILL STALLS, it is usually because it is being overloaded or improperly used. To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit through the last fractional part of the hole. Keep the motor running when pulling the bit back out of a drilled hole. With variable speed drills there is no need to center punch the point to be drilled. [. . . ]
