All users and bystanders must wear eye protection that conforms to ANSI Z87.1. 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. Wear protective clothing and wash exposed areas with soap and water. 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. Always use NIOSH/OSHA approved respiratory protection appropriate for the dust exposure. Direct particles away from face and body. • The label on your tool may include the following symbols. The symbols and their definitions are as follows: V ....................volts A ....................amperes Hz ..................hertz W ...................watts min ................minutes .................alternating current .............direct current no..................no load speed ..................Class I Construction ...................earthing terminal (grounded) ..................safety alert symbol ..................Class II Construction …/min ............revolutions or reciprocation (double insulated) per minute BPM ..............beats per minute SAVE THESE INSTRUCTIONS Motor Be sure your power supply agrees with the nameplate marking. Voltage decrease of more than 10% will cause loss of power and overheating. DEWALT tools are factory tested; if this tool does not operate, check power supply. COMPONENTS (FIG. 1, 2, 3) WARNING: Never modify the power tool or any part of it. Damage or personal injury could result. A. Trigger switch B. Reversing lever C. Bubble level D. Bubble level bulls-eye E. Keyless chuck Keyed chuck (not shown) INTENDED USE The heavy-duty V.S.R. drills are designed for professional drilling at various work sites (i.e., construction sites). DO NOT use under wet conditions or in presence of flammable liquids or gases. These heavy-duty V.S.R. drills are professional power tools. DO NOT let children come into contact with the tool. Supervision is required when inexperienced operators use this tool. Switches (Fig. 1) To start the drill, depress the trigger switch; to stop the drill, release the trigger. A variable speed trigger switch (A) permits speed control—the farther the trigger is depressed, the higher the speed of the drill. NOTE: Use lower speeds for starting holes without a center punch, drilling in metal or plastics, driving screws or drilling ceramics. Higher speeds are better for drilling wood and composition boards and using abrasive and polishing accessories. The reversing lever (B) is used for withdrawing bits from tight holes and removing screws. It is located above the trigger switch. To reverse the motor, release the trigger switch FIRST and then push the lever to the right. After any reversing operations, return lever to forward position. OPERATION WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool from power source before making any adjustments or removing/installing attachments or accessories. Drilling WARNING: To reduce the risk of personal injury, ALWAYS ensure workpiece is anchored or clamped firmly. If drilling thin material, use a wood “back-up” block to prevent damage to the material. 1. Use sharp drill bits only. For WOOD, use twist drill bits, spade bits, power auger bits, or hole saws. For METAL, use steel twist drill bits or hole saws. For MASONRY, such as brick, cement, cinder block, etc., use carbide-tipped bits rated for percussion drilling....
