GENERAL SAFETY RULES
WARNING! Read and understand all instructions.
Failure to follow all instructions listed
below may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
• Keep your work area clean and well lit.
Cluttered benches and dark areas invite accidents.
•
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.
•
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can
cause you to lose control.
Electrical Safety
• Grounded tools must be plugged into an outlet properly installed and grounded in
accordance with all codes and ordinances. Never remove the grounding prong or modify the
plug in any way. Do not use any adaptor plugs. Check with a qualified electrician if you are in
doubt as to whether the outlet is properly grounded.
If the tools should electrically malfunction
or break down, grounding provides a low resistance path to carry electricity away from the user.
Applicable only to Class I (Grounded) tools.
• Double insulated tools are equipped with a polarized plug (one blade is wider than the other.)
This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet,
reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet.
Do not change the plug in any way.
Double Insulation
eliminates the need for the three wire
grounded power cord and grounded power supply system. Applicable only to Class ll tools.
•
Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is grounded.
•
Don’t expose power tools to rain or wet conditions.
Water entering a power tool will increase
the risk of electric shock.
•
Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet.
Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords
immediately.
Damaged cords increase the risk of electric shock.
•
When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W.”
These cords are rated for outdoor use and reduce the risk of electric shock.
Personal Safety
• Stay alert, watch what you are doing and use common sense when operating a power tool.
Do not use tool while tired or under the influence of drugs, alcohol, or medication.
A moment
of inattention while operating power tools may result in serious personal injury,
•
Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair,
clothing, and gloves away from moving parts.
Loose clothes, jewelry, or long hair can be
caught in moving parts.
•
Avoid accidental starting. Be sure switch is off before plugging in.

Not Recommended
finger on the switch or plugging in tools that have the switch on invites accidents.
•
Remove adjusting keys or wrenches before turning the tool on.
A wrench or a key that is left
attached to a rotating part of the tool may result in personal injury.
•
Do not overreach. Keep proper footing and balance at all times.
Proper footing and balance
enables better control of the tool in unexpected situations.
•
Use safety equipment. Always wear eye protection.
Dust mask, non-skid safety shoes, hard hat,
or hearing protection must be used for appropriate conditions.
Tool Use and Care
• 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 force tool. Use the correct tool for your application.
The correct tool will do the job better
and safer at the rate for which it is designed.
•
Do not use tool if switch does not turn it on or off.
Any tool that cannot be controlled with the
switch is dangerous and must be repaired.
•
Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing the tool.
Such preventive safety measures reduce the risk of starting the
tool accidentally.
•
Store idle tools out of reach of children and other untrained persons.
Tools are dangerous in
the hands of untrained users.
•
Maintain tools with care. Keep cutting tools sharp and clean.
Properly maintained tools, with
sharp cutting edges are less likely to bind and are easier to control.
•
Check for misalignment or binding of moving parts, breakage of parts, and any other
condition that may affect the tools operation. If damaged, have the tool serviced before using.
Many accidents are caused by poorly maintained tools.
•
Use only accessories that are recommended by the manufacturer for your model.
Accessories
that may be suitable for one tool, may become hazardous when used on another tool.
Service
• Tool service must be performed only by qualified repair personnel.
Service or maintenance
performed by unqualified personnel could result in a risk of injury.
•
When servicing a tool, use only identical replacement parts. Follow instructions in the
Maintenance section of this manual.
Use of unauthorized parts or failure to follow Maintenance
Instructions may create a risk of electric shock or injury.
SPECIFIC SAFETY RULES
•
Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may
contact hidden wiring or its own cord.
Contact with a "live" wire will make exposed metal parts of the tool
"live" and shock the operator.
WARNING:
Some dust created by power sanding, sawing, grinding, drilling, and other construction activ-
ities 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. (CCA)
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your expo-
sure 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.

OPERATION
MOTOR
Your drill is powered by a Black & Decker built motor. Be sure your power supply agrees with the nameplate
marking. A marking of 120 volts, 50/60 Hz or 120 volts, AC only means that the tool is designed to oper-
ate on normal 120 volt house current. Voltage decrease of more than 10% will cause loss of power and over-
heating. All Black & Decker tools are factory tested. If this tool does not run, check the power supply.
LOCK-ON BUTTON
To start drill, depress trigger switch; to stop drill, release trigger. To lock trigger in ON position for continuous
operation, depress trigger and push up lock-on button "A" shown in Figure 1, then gently release trigger. To
release locking mechanism, depress trigger fully, then release it. Before using the tool (each time) be sure that
the lock-on button release mechanism is working freely. Do not lock the switch ON when drilling by hand so
that you can instantly release then trigger switch if the bit binds in the hole. The lock-on button is for use only
when the drill is mounted in a drill press stand or otherwise held stationary. Be sure to release the lock-on but-
ton before disconnecting the plug from the power supply. Failure to do so will cause the tool to start immedi-
ately the next time it is plugged in. Damage or injury could result.
VARIABLE SPEED SWITCH
This permits FREE HAND speed control—the further the trigger is depressed, the higher the R.P.M. Use lower
speeds for starting holes without a center punch, drilling in metal, plastics, and ceramics, or driving screws.
Higher speeds are better for drilling wood and composition boards, and for using abrasive and polishing
accessories.
REVERSING LEVER
The reversing lever is used for withdrawing bits from tight holes and removing screws. It is located above the
trigger switch (Fig. 2). To reverse the motor, release the trigger FIRST and then push the lever to the right. After
any reversing operations, return lever to forward position.
