Additional Safety Information; Intended Use - DeWalt DWE7491 Manual De Instrucciones

English
• Always wear gloves for handling saw blades and rough material. Saw blades should be carried in
a holder wherever practicable.

Additional Safety Information


WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses.
Also use face or dust mask if cutting operation is dusty. 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 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.
• 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 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.
