Safety Rules for Cordless Hammer Drills
a. Wear ear protectors when impact drilling.
Exposure to noise can cause hearing loss.
b. Use the auxiliary handle(s). Loss of control
can cause personal injury.
c. Hold the power tool by insulated gripping
surfaces, when performing an operation
where the cutting accessory or fasteners
may contact hidden wiring. Cutting
accessory or fasteners contacting a "live"
wire may make exposed metal parts of the
power tool "live" and could give the operator
an electric shock.
d. Use clamps or another practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand
or against your body leaves it unstable and
may lead to loss of control.
e. Do not drill, fasten or break into existing
walls or other blind areas where electrical
wiring may exist.
unavoidable, disconnect all fuses or circuit
breakers feeding this worksite.
f. Always wear safety goggles or eye
protection when using this tool. Use a dust
mask or respirator for applications which
generate dust.
g. 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.
h. 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.
i. 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.

j. 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.
k. If the bit becomes bound in the workpiece,
release the trigger immediately, reverse the
direction 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.
l. Do not grasp the tool or place your hands
too close to the spinning chuck or drill bit.
Your hand may be lacerated.
m. 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.
n. Do not use dull or damaged bits and
accessories. Dull or damaged bits have a
greater tendency to bind in the workpiece.
o. 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.
p. 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.
q. Do not run the tool while carrying it at your
side. A spinning drill bit could become
entangled with clothing and injury may
result.
