Intended Use
Your Black & Decker hammer drill has been designed for drilling in wood, metal, plastics and
masonry as well as for screwdriving purposes.
This tool is intended for consumer use only.
Safety Instructions
When using power tools, always observe the safety regulations applicable in your
country to reduce the risk of fire, electric shock, personal injury and material damage.
Read the following safety instructions before attempting to operate this product. Keep
these instructions in a safe place!
The following symbols are used throughout this manual:
Denotes risk of personal injury, loss of life or damage to the tool in case of non-observance
of the instructions in this manual.
Denotes risk of electric shock.
Fire hazard.
Work Area
Keep work area clean and bright. Cluttered areas and benches can cause accidents.
Keep work area well lit (250-300 Lux).
Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create sparks that may ignite the dust
or fumes.
Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
Electrical Safety
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.
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.
Do not 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 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.
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.
Personal Safety
Stay alert. Watch what you are doing. Use common sense. Do not operate the
tool when 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.
Use safety equipment. Always wear eye protection. Everyday eyeglasses only have
impact resistant lenses, they are not safety glasses. Contain long hair. Safety equipment
such as dust mask, non-skid safety shoes, hardhat, heat-resistant apron or hearing
protection used for appropriate conditions will reduce personal injuries.
Avoid accidental starting. Ensure the switch is in the off position before plugging
in. Carrying power tools with your finger on the switch or plugging in power tools that have
the switch on invites accidents.
Remove any adjusting key or wrench before turning the power tool on. A wrench
or a key left attached to a rotating part of the power tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewelery. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jeweler or long hair can be caught
in moving parts.
If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of these devices
can reduce dust related hazards.
Secure workpiece. Use clamps or a vice to hold the workpiece. It is safer and it frees
both hands to operate the tool.
Power tool use and care
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.
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.
Disconnect the plug from the power source before making any adjustments,
changing accessories, or storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
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.
Maintain power tools. Check for misalignment or binding of moving parts, break-
age of parts and any other condition that may affect the power tools operation. If
damaged, have the power tool repaired before use. Many accidents are caused by poorly
maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc., in accordance with these
instructions and in the manner intended for the particular type of power tool, 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.
Service
Have your power tool serviced by a qualified repairperson using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
Additional Safety Instructions for Hammer
Drills
Wear ear protectors with impact drills. Exposure to noise can cause hearing loss.
Use auxiliary handles supplied with the tool. Loss of control can cause personal injury.
Keep your drill bits sharp for best and safest performance.
When fitting and changing accessories, always use the instructions supplied with the
accessory.
Should your hammer drill develop a fault, do not try to fix it yourself, but take it to one of
our authorized repair agents.
Make sure that the switch is in the “off” position before you plugging in or putting down the tool.
Do not force your hammer drill – it will do a better and safer job at the speed for which
it was designed.

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 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.
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.

Double Insulation
The tool is double insulated. Double insulation means that all the external metal parts are
electrically insulated from the mains power supply. This is done by placing insulated
barriers between the electrical and mechanical components so as to making unnecessary for
the tool to be earthed. NOTE: Double insulation does not take the place of normal safety
precautions when operating this tool. The insulation system is for added protection against
injury resulting from a possible electrical insulation failure within the tool.
Electrical safety
The electric motor has been designed for one voltage only. Always check that the power supply
corresponds to the voltage on the rating plate.
Warning: Never connect the live (L) or neutral (N) wires to the earth pin marked E or .
Using an Extension Cable
An extension cable should not be used unless absolutely necessary. Use of an improper
extension cable could result in a risk of fire and electric shock. If an extension cable must be
used, use only those that are approved by the country’s Electrical Authority. Make sure that
extension cord is in good condition before using. Always use the cord that is suitable for the
power input of your charger (see technical data on name plate).
When using a cable reel, always unwind the cable completely.

Handy Hints
Drilling
WARNING: Drill may stall (if overloaded or improperly used) causing a twist. Always
expect the stall. Grip the drill firmly to control the twisting action (see Fig. F) and prevent
loss of control that could cause personal injury. If a stall does occur, release the trigger
immediately and determine the reason for the stall before re-starting. Do not click the
trigger of a stalled drill off and on in an attempt to start it. Damage to the drill can result.
Always apply a light pressure in a straight line with the drill bit. Run the drill very slowly,
using light pressure, until the hole is started enough to keep the drill bit from slipping out of it.
Use a block of wood to back up work pieces that may splinter.
Use spade bits when drilling large diameter holes in wood.
Use HSS drill bits when drilling in metal.
Use masonry bits when drilling in soft masonry.
Use a lubricant when drilling metals other than cast iron and brass.
Make an indentation using a center punch at the center of the hole to be drilled in order to
improve accuracy.
Keep the motor running while pulling the bit out of a drilled hole. This will help reduce jamming.
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.
Screwdriving
Always use the correct type and size of screwdriver bit.
If screws are difficult to tighten, try applying a small amount of washing liquid or soap as a lubricant.
Always hold the tool and screwdriver bit in a straight line with the screw.
