Drill/Driver/Hammerdrill Safety Warnings
• Wear ear protectors when impact drilling. Expo,_ure to noi,_e
can cause hearing loss.
• Use auxiliary handle(s), if supplied with the tool. Loss of
control can cause personal injury.
• Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting accessory may
contact hidden wiring. Cutting accessory contacting a "live" wire
may make exposed metal parts of the power tool "live" and could
give the operator an electric shock.
• Use clamps or otherpractical way to secure and support the
workpiece to a stable platform. Holding the work by hand or
against your body is unstable and may lead to loss of control.
• Wear safety goggles or other eye protection. Hammering and
drilling operations cause chips to fly. Flying particles can cause
permanent eye damage.
• Always use the side handle supplied with the tool. 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.
• Accessories and tool may get hot during operation. Wear
gloves when handling them if performing heat producing applications
such as hammerdrilling and drilling metals.
• 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.
• Air vents often cover moving parts and should be avoided.
Loose clothes, jewelry or long hair can be caught in moving parts.
A 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 $12.6 ($3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
i_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.
