SAFETY WARNINGS FOR HAMMER DRILL
Wear ear protectors when impact drilling.
•
Exposure to noise can cause hearing loss.
Hold the power tool by insulated gripping
•
surfaces, when performing an operation
where the cutting accessory or fastener
may contact hidden wiring. The cutting
accessory or fastener contacting a "live" wire
may make exposed metal parts of the power
tool "live" and could give the operator an
electric shock.
Secure the work piece. Clamping devices or
•
a vise will hold the work piece in place better
and more safely than holding it by hand.
Do not drill, fasten or break into existing
•
walls or other blind areas where electrical
wiring may exist. If this situation is
unavoidable, disconnect all fuses or circuit
breakers feeding this worksite.
Position yourself to avoid being caught
•
between the tool or side handle and walls
or posts. Should the bit become bound or
jammed in the work, the reaction torque of the
tool could crush your hand or leg.
Safety instructions when using long
drill bits:
Never operate at higher speed than the
•
maximum speed rating of the drill bit.
At higher speeds, the bit is likely to bend if
allowed to rotate freely without contacting the
workpiece, resulting in personal injury.
Always start drilling at low speed and with
•
the bit tip in contact with the workpiece.
At higher speeds, the bit is likely to bend if
allowed to rotate freely without contacting the
workpiece, resulting in personal injury.
Apply pressure only in direct line with the
•
bit and do not apply excessive pressure.
Bits can bend causing breakage or loss of
control, resulting in personal injury.
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, cement, and
–
other masonry products.
Arsenic and chromium from chemically-treated
–
lumber.
Your risk from these exposures varies,
•
depending upon how often you do this type
of work. To reduce your exposure to these
chemicals:
Work in a well-ventilated area.
–
Work with approved safety equipment, such
–
as 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 or eyes or
to lie on the skin may promote absorption of
harmful chemicals.
