User manual DEWALT DW511

[. . . ] Any tool that cannot be controlled with the switch is dangerous and must be repaired. ⷠDisconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventative safety measures reduce the risk of starting the tool accidentally. ⷠStore idle tools out of reach of children and other untrained persons. [. . . ] 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. 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. Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption of harmful chemicals. WARNING: Use of this tool can generate and/or disburse dust, which may cause serious and permanent respiratory or other injury. CAUTION: Always use side handle when provided and hold hammerdrill with both hands. It clamps to the front of the gear case as shown in Figure 1 and can be rotated 360° to permit right or left hand use. To lock the trigger switch in the ON position for continuous operation, depress the trigger switch and push up the locking button (B). To turn the tool OFF, from a locked ON condition, squeeze and release the trigger once. Before using the tool (each time), be sure that the locking button release mechanism is working freely. Do not lock the switch ON when drilling by hand so that you can instantly release the trigger switch if the bit binds in the hole. The locking button is for use only when the hammerdrill is mounted in a drill press stand or other wise held stationary. Be sure to release the locking mechanism before disconnecting the plug from the power supply. [. . . ] To adjust the depth rod, loosen the handle and move rod so that the distance between the end of the rod and the end of the bit equals the desired drilling depth. When drilling with depth rod, stop when end of rod reaches surface of material. CLEANING & LUBRICATION Use only mild soap and damp cloth to clean the tool. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid. [. . . ]
