DeWalt DW970 Manual De Instrucciones página 5

• STAY ALERT. Watch what you are doing. Use common sense.
Do not operate tool when you are tired.
• CHECK DAMAGED PARTS. Before further use of the tool, a
guard or other part that is damaged should be carefully checked
to determine that it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of moving
parts, breakage of parts, mounting, and any other conditions
that may affect its operation. A guard or other part that is
damaged should be properly repaired or replaced by an
authorized service center unless otherwise indicated elsewhere
in this instruction manual. Have defective switches replaced by
authorized service center. Do not use tool if switch does not turn
it on and off.
• DO NOT OPERATE portable electric tools near flammable
liquids or in gaseous or explosive atmospheres. Motors in these
tools normally spark, and the sparks might ignite fumes.
• BE AWARE that this tool is always in an operating condition
because it does not have to be plugged into an electrical outlet.
Keep the switch control lever in the lock "OFF" position, as
shown in Figure 5c, when you are not using the tool.
CAUTION: When drilling or driving into walls, floors or
wherever "live" electrical wires may be
encountered, DO NOT TOUCH ANY
FRONT METAL PARTS OF THE TOOL!
Hold the tool only by the plastic handle to
prevent shock if you drill or drive into a
"live" wire.
WARNING: To control twisting action,
place both hands on drill (see Figure A).
Additional Safety Rules
• Hold tool by insulated gripping surfaces when performing
an operation where the tool may contact hidden wiring.
Contact with a "live" wire will also make exposed metal parts of
the tool "live" and shock the operator.

BATTERY PACK
• When working on a ladder or on scaffolding be sure to lay
the tool down on its side when not in use. Some tools with
large battery packs will stand upright but may be easily knocked
over.
W A R N I N G G : 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
FIG. A
• 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.
