GENERAL POWER TOOL SAFETY WARNINGS
WARNING!
warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence
of flammable liquids, gases or dust. Power tools create sparks which may ignite
the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions
can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do
not use any adapter plugs with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric shock if
your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging
the power tool. Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a ground fault
circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of
electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inattention while operating power
tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective
equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position before
connecting to power source and/or battery pack, picking up or carrying the
tool. Carrying power tools with your finger on the switch or energizing power tools
that have the switch on invites accidents.
Read all safety warnings and instructions. Failure to follow the
2
d) Remove any adjusting key or wrench before turning the power tool on. A wrench
r a key left attached to a rotating part of the power tool may result in personal injury.
o
e) Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jewelry or long hair can be
caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust collection
can reduce dust-related hazards.
44))
Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application.
The correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power
tool that cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the
power tool before making any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce the risk of starting the power
tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power toolʼs
operation. If damaged, have the power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc., in accordance with these
instructions, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from those intended could
result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
SPECIFIC SAFETY RULES
• Hold tool by insulated gripping surfaces when performing an operation where the
tool may contact hidden wiring or its own cord. Contact with a “live” wire will also
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.
• When working on a ladder or on scaffolding be sure to lay the tool down on its
side when not in use. Some tools with large battery packs will stand upright but may
be easily knocked over.
WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses.
Also use face or dust mask if drilling operation is dusty. ALWAYS WEAR CERTIFIED
SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA respiratory protection.
WARNING: 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.
3
• 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, eyes, or lay on the skin may
promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust, which may cause
serious and permanent respiratory or other injury. Always use NIOSH/OSHA approved
respiratory protection appropriate for the dust exposure. Direct particles away from face
and body.
• When using an extension cord, be sure to use one heavy enough to carry the current
your product will draw. An undersized cord will cause a drop in line voltage resulting in
loss of power and overheating. The following table shows the correct size to use
depending on cord length and nameplate ampere rating. If in doubt, use the next heavier
gauge. The smaller the gauge number, the heavier the cord.

Motor
Your Black & Decker tool is powered by a Black & Decker-built motor. Be sure your power
supply agrees with nameplate marking. 120 Volts AC only means your drill will operate on
standard 60 Hz household power. Do not operate AC tools on DC. A rating of 120 volts
AC/DC means that your tool will operate on standard 60 Hz AC or DC power. This
information is printed on the nameplate. Lower voltage will cause loss of power and can
result in over-heating. All Black & Decker tools are factory-tested; if this tool does not
operate, check the power supply.

With the trigger switch released, slide the reversing switch, (Fig. 2) to align with the arrow
pointing forward for drilling or toward the arrow pointing backward for running in reverse.
After all reversing operations, switch the tool to the forward running mode.
NOTE: WHEN THE REVERSING SWITCH IS IN NEUTRAL THE DRILL WILL NOT
OPERATE. DO NOT FORCE TRIGGER. SELECT FORWARD OR REVERSE BEFORE
TURNING DRILL ON.
KEYLESS CHUCK OPERATION
This tool is equipped with a feature that automatically locks the spindle when the tool is not
running. This feature is a normal condition which allows for tightening or loosening of the
chuck with one hand while holding the drill with the other. Loosen the chuck by rotating the
sleeve counterclockwise (Fig. 3). Insert the bit or other accessory fully into the chuck, and
tighten securely by rotating the sleeve in the clockwise direction as viewed from the chuck
end.
Drilling
• Always unplug the drill when attaching or removing accessories. When using a keyless
chuck, hand tighten firmly.
• Use sharp drill bits only.
• Support and secure work properly, as instructed in the Safety Instructions.
• Use appropriate and required safety equipment, as instructed in the safety instructions.
• Secure and maintain work area, as instructed in the safety instructions.
• Run the drill very slowly, using light pressure, until the hole is started enough to keep the
drill bit from slipping out of it.
• Apply pressure in a straight line with the bit. Use enough pressure to keep the bit biting
but not so much as to stall the motor or deflect the bit.
• Hold the drill firmly to control its twisting action.
• DO NOT CLICK THE TRIGGER OF A STALLED DRILL OFF AND ON IN AN ATTEMPT
TO START IT. DAMAGE TO THE DRILL CAN RESULT.
• Minimize stalling on breakthrough by reducing pressure and slowly drilling through the
last part of the hole.

jamming.
• Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which
should be drilled dry. The lubricants that work best are sulphurized cutting oil or lard oil.
Bacon grease will also serve.
• When using twist drill bits to drill holes in wood, it will be necessary to pull the bits out
frequently to clear chips from the flutes.
• Plug in drill. Make sure switch turns drill on and off.
