Porter Cable 557 Manual De Instrucciones página 5

• 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 smaller the
gauge number, the heavier the cord.

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.
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.
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.
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.
• The label on your tool may include the following symbols. The symbols and their
definitions are as follows:
