General Safety Instructions

WARNING! Read and understand all instructions. Failure to follow all instruc-
tions 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 flam-
mable 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 elec-
tician 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
inates the need for the three wire grounded power cord and grounded power supply system.
Applicable only to Class II (double insulated) 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 medica-
tion. 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.
Air vents often cover moving parts and should also be avoided.
• Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with
your 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 bal-
ance 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 preventative safety measures reduce the risk of
starting the tool accidentally.
• Store idle tools out of reach of children and other untrained persons. Tools are dan-
gerous 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 mainte-
nance 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.
Additional Specific Safety Instructions
•• Hold tool by insulated gripping surfaces when performing an operation where the cut-
ting tool may contact hidden wiring. Contact with a "live" wire will make exposed metal
parts of the tool "live" and shock the operator.
• Wear safety goggles or other eye protection. Hammering and drilling operations cause
chips to fly. Flying particles can cause permanent eye damage.
• Bits, sockets and tools get hot during operation. Wear gloves when touching them.
• Do not operate this tool for long periods of time. Vibration caused by tool action may be
harmful to your hands and arms. Use gloves to provide extra cushion and limit exposure by
taking frequent rest periods.
CAUTION: Wear appropriate hearing protection during use. Under some conditions and
duration of use, noise from this product may contribute to hearing loss.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con-
struction activities contains chemicals known to cause cancer, birth defects or other reproduc-
tive 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 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 pro-
mote 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.

Motor
Your D WALT tool is powered by a D
E
the nameplate marking.
Volts 50/60 Hz or "AC only" means your tool must be operated on alternating current and never
with direct current.
Voltage decrease of more than 10% will cause loss of power and overheating. D
are factory tested; if this tool does not operate, check power supply.
elim-
Motor Brushes
This D WALT tool uses an advanced brush system which automatically stops the tool when the
E
brushes wear out. This prevents serious damage to the motor.
Switch
Pressing the BOTTOM part of the switch runs the tool in forward (right hand thread) direction.
Pressing the TOP of the switch reverses motor direction. This allows "rocking" fasteners to break
them loose.
Anvil with Detent Pin
To install a socket on the anvil, align the hole in the side of the socket with the detent pin on the
anvil. Press the socket on until the detent pin engages in the hole. To remove a socket, depress
the detent pin through the hole, using a small, pointed object, and pull the socket off.
Impact Time
Many variables exist that will cause the torque available on any fastener to vary considerably.
The optimum impact time is about 6 seconds.
Capacity
Your 1/2" impact wrench uses sockets with 1/2" square drive ends. A 3/4" impact wrenche uses
sockets with 3/4" square drive ends. Both sizes of impact wrenches are capable of driving the
same range of hex impact sockets available.
In particularly heavy duty usage the 3/4" drive impact wrench has an extra strong anvil that will
resist breakage.
Lubrication
Your tool was properly lubricated before leaving the factory. In from two to six months, depend-
ing upon use, take or send your tool to a Black & Decker (U.S.) Inc. Industrial Service Center
or other qualified service organization for a complete cleaning, inspection and relubrication.
Tools used constantly on production or heavy duty jobs or exposed to heat may require more
frequent lubrication. Tools "out of service" for long periods should be relubricated before being
put back into service.
