Dewalt D25911K Instruction Manual - Page 8

English  WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California 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. 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 disperse 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.  WARNING: Always wear proper personal hearing protection that conforms to ANSI S12.6 (S3.19) during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss. • Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or lie on the skin may promote absorption of harmful chemicals. Direct particles away from face and body. • Use the appropriate dust extractor vacuum to remove the vast majority of static and airborne dust. Failure to remove static and airborne dust could contaminate the working environment or pose an increased health risk to the operator and those in close proximity. • Use clamps or other practical ways to secure and support the workpiece to a stable platform. Holding the workpiece by hand or against your body is unstable and may lead to loss of control and injury. • Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long hair can be caught in moving parts. • An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is, 16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size. The following table shows the correct 6 size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The lower the gauge number, the heavier the cord. Minimum Gauge for Cord Sets Volts Total Length of Cord in Feet (meters) 120V 25 (7.6) 50 (15.2) 100 (30.5) 150 (45.7) 240V 50 (15.2) 100 (30.5) 200 (61.0) 300 (91.4) Ampere Rating More Not Than More American Wire Gauge Than 0 6 18 16 16 14 6 10 18 16 14 12 10 12 16 16 14 12 12 16 14 12 Not Recommended The label on your tool may include the following symbols. The symbols and their definitions are as follows: V volts or AC/DC..... alternating or Hz hertz direct current min minutes Class II Construction or DC.......direct current (double insulated) Class I Construction no no load speed (grounded) n rated speed .../min per minute PSI pounds per square inch BPM beats per minute earthing terminal IPM impacts per minute safety alert symbol OPM oscillations per minute visible radiation- do not stare into RPM revolutions per minute the light sfpm surface feet per minute wear respiratory SPM strokes per minute protection A amperes wear eye protection W watts Wh watt hours Ah amp hours or AC alternating current wear hearing protection read all documentation do not expose to rain Motor Be sure your power supply agrees with the nameplate marking. Voltage decrease of more than 10% will cause loss of power and overheating. These tools are factory tested; if this tool does not operate, check power supply. Soft Start Feature The soft start feature allows the impact rate to build up more slowly, thus preventing the chisel or point from "bouncing" around on the masonry when starting up. Active Vibration Control The active vibration control neutralizes rebound vibration from the hammer mechanism. Lowering hand and arm vibration, it allows more comfortable use for longer periods of time and extends the life of the unit.
