Safety Rules for Cordless Hammer Drills
H
old power tools by insulated gripping
surfaces when performing an operation
where the cutting tools may contact hidden
wiring.
Contact with a “live” wire will make
exposed metal parts of the tool “live” and
shock the operator.
Use clamps or other practical 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.
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.
Wear ear protectors when using the tool for
extended periods.
Prolonged exposure to
high intensity noise can cause hearing loss.
Always use auxiliary handle for maximum
control over torque reaction or kick-back.
High torque 3/8" and larger chuck capacity
drills are equipped with auxiliary handles.
Always wear safety goggles or eye
protection when using this tool. Use a dust
mask or respirator for applications which
generate dust.
Use thick cushioned gloves and limit the
exposure time by taking frequent rest
periods.
Vibration caused by hammer-drill
action may be harmful to your hands and
arms.
Secure the material being drilled. Never
hold it in your hand or across legs.
Unstable support can cause the drill bit to bind
causing loss of control and injury.
Disconnect battery pack from tool before
making any assembly, adjustments or
changing accessories
. Such preventive
safety measures reduce the risk of starting the
tool accidentally.
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.
If the bit becomes bound in the workpiece,
release the trigger immediately, reverse the
d
irection of rotation and slowly squeeze
the trigger to back out the bit.
Be ready for
a strong reaction torque. The drill body will
tend to twist in the opposite direction as the
drill bit is rotating.
Do not grasp the tool or place your hands
too close to the spinning chuck or drill bit.
Your hand may be lacerated.
When installing a drill bit, insert the shank
of the bit well within the jaws of the chuck.
If the bit is not inserted deep enough, the grip
of the jaws over the bit is reduced and the loss
of control is increased.
Do not use dull or damaged bits and
accessories.
Dull or damaged bits have a
greater tendency to bind in the workpiece.
When removing the bit from the tool avoid
contact with skin and use proper protective
gloves when grasping the bit or accessory.
Accessories may be hot after prolonged use.
Check to see that keys and adjusting
wrenches are removed from the drill before
switching the tool "ON".
Keys or wrenches
can fly away at high velocity striking you or a
bystander.
Do not run the tool while carrying it at your
side.
A spinning drill bit could become
entangled with clothing and injury may result.
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
• 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.
