n. 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.
o. Do not run the drill while carrying it at
your side. A spinning drill bit could
become entangled with clothing and
injury may result.
Safety instructions when using
long drill bits
a. Never operate at higher speed than the
maximum speed rating of the drill bit.
GFCI and personal protection devices like
electrician's rubber gloves and footwear will
further enhance your personal safety.
Do not use AC only rated tools with a DC
power supply. While the tool may appear to
work, the electrical components of the AC
rated tool are likely to fail and create a hazard
to the operator.
Keep handles dry, clean and free from oil
and grease. Slippery hands cannot safely
control the power tool.
Develop a periodic maintenance schedule for
your tool. When cleaning a tool be careful
not to disassemble any portion of the tool
since internal wires may be misplaced or
pinched or safety guard return springs may
be improperly mounted. Certain cleaning
agents such as gasoline, carbon tetrachloride,
ammonia, etc. may damage plastic parts.
Ensure the switch is in the off position
before inserting battery pack. Inserting the
battery pack into power tools that have the
switch on invites accidents.

At higher speeds, the bit is likely to
bend if allowed to rotate freely without
contacting the workpiece, resulting in
personal injury.
b. 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.
c. 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.
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.
Before using battery charger, read all
instructions and cautionary markings on (1)
battery charger, (2) battery pack, and (3)
product using battery.
Do not disassemble charger or operate the
charger if it has received a sharp blow, been
dropped or otherwise damaged in any way.
Replace damaged
immediately. Incorrect reassembly or
damage may result in electric shock or fire.
