DeWalt D25980 Manual De Instrucciones página 3

Be certain that the material being worked does not conceal electric or gas service and that
their locations have been verified with the utility companies.
• Wear ear protectors. Exposure to noise can cause hearing loss.
• Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.
Keep a firm grip on the tool at all times. Do not attempt to operate this tool without
holding it with both hands. Operating this tool with one hand will result in loss of control.
Breaking through or encountering hard materials such as re-bar may be hazardous as well.
Tighten the side handle securely before use.
• Wear safety goggles or other eye protection. Hammering operations cause chips to
fly. Flying particles can cause permanent eye damage. Wear a dust mask or respirator for
applications that generate dust. Ear protection may be required for most applications.
• Do not operate this tool for long periods of time. Vibration caused by hammer action may
be harmful to your hands and arms. Use gloves to provide extra cushion and limit exposure
by taking frequent rest periods.
• Do not recondition bits yourself. Chisel reconditioning should be done by an authorized
specialist. Improperly reconditioned chisels could cause injury.
• Wear gloves when operating tool or changing bits. Accessible metal parts on the tool and
bits may get extremely hot during operation. Small bits of broken material may damage bare
hands.
• Never lay the tool down until the bit has come to a complete stop. Moving bits could
cause injury.
• Do not strike jammed bits with a hammer to dislodge them. Fragments of metal or
material chips could dislodge and cause injury.
• Slightly worn chisels can be resharpened by grinding.
• Keep the power cord away from the bit. Do not wrap the cord around any part of your
body. An electric cord wrapped around a bit may cause electric shock.
WARNING: ALWAYS wear certified safety equipment:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
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.
WARNING: ALWAYS use respiratory protection. All users and bystanders must wear respi-
ratory protection that conforms to NIOSH/OSHA/MSHA standards.
WARNING: ALWAYS use eye protection. Everyday eyeglasses are NOT safety glasses. All
users and bystanders must wear eye protection that conforms to ANSI Z87.1.
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.
