Additional Specific Safety Rules - DeWalt DW937 Manual De Instrucciones

changing accessories, or storing the tool. Such preventative
safety measures reduce the risk of starting the tool accidentally.
• Store idle tools out of reach of children and other untrained
persons. Tools are dangerous in the hands of untrained users.
• When battery pack is not in use, keep it away from other metal
objects like: paper clips, coins, keys, nails, screws, or other
small metal objects that can make a connection from one ter-
minal to another. Shorting the battery terminals together may
cause sparks, burns, or a fire.
• Maintain tools with care. Keep cutting tools sharp and clean.
Properly maintained tools, with sharp cutting edges are less likely
to bind and are easier to control.
• Check for misalignment or binding of moving parts, breakage
of parts, and any other condition that may affect the tool's
operation. If damaged, have the tool serviced before using.
Many accidents are caused by poorly maintained tools.
• Use only accessories that are recommended by the manufac-
turer for your model. Accessories that may be suitable for one
tool, may become hazardous when used on another tool.
SERVICE
• Tool service must be performed only by qualified repair per-
sonnel. Service or maintenance performed by unqualified person-
nel could result in a risk of injury.
• When servicing a tool, use only identical replacement parts.
Follow instructions in the Maintenance section of this manu-
al. Use of unauthorized parts or failure to follow Maintenance
Instructions may create a risk of electric shock or injury.

Additional Specific Safety Rules

• Hold tool by insulated gripping surfaces when performing an
operation where the cutting tool may contact hidden wiring.
Contact with a "live" wire will make exposed metal parts of the tool
"live" and shock the operator.
• Keep hands away from moving parts. Never place your hands
near the cutting area.
• Use extra caution when cutting overhead and pay particular
attention to overhead wires which may be hidden from view.
Anticipate the path of falling branches and debris ahead of time.
CAUTION: When sawing into walls, floors or wherever "live" electri-
cal wires may be encountered, DO NOT TOUCH ANY METAL PARTS
OF THE TOOL! Hold the tool only by the plastic handle and housing to
prevent electric shock if you saw into a "live" wire.
CAUTION: Wear appropriate personal hearing protection dur-
ing use. Under some conditions and duration of use, noise from this
product may contribute to hearing loss.
CAUTION: A dust mask or respirator should be worn by all persons
entering the work area. The filter should be replaced daily or when-
ever the wearer has difficulty breathing. See your local hardware store
for the proper NIOSH/OSHA approved dust mask.
CAUTION: When not in use, place tool on its side on a stable
surface where it will not cause a tripping or falling hazard. Some
tools with large battery packs will stand upright on the battery pack but
may be easily knocked over.
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 exam-
ples 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 equip-
ment, such as those dust masks that are specially designed to filter
out microscopic particles.
