WARNING
The operation of any power tool can result in foreign objects being thrown into your eyes,
which can result in severe eye damage. Before beginning power-tool operation, always
wear safety goggles or safety glasses with side shields and a full-face shield, when
needed. We recommend using a wide vision safety mask over eyeglasses or standard
safety glasses with shields. Always use eye protection marked to comply with ANSI Z87.1.
DANGER
People with electronic devices, such as pacemakers, should consult their physician(s)
before using this product. Operation of electrical equipment in close proximity to a heart
pacemaker could cause interference or failure of the pacemaker.
WARNING
Some dust created by power sanding, sawing, grinding, drilling and other construction
activities contains chemicals known to the state of California 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 chemical: work in a well-ventilated area, and work with
approved safety equipment, such as those dust masks that are specially designed to lter
out microscopic particles.

SAFETY INFORMATION
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.
Work Area Safety
• Keep work area clean and well lit. Cluttered and dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of
ammable liquids, gases or dust. Power tools create sparks which 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. Unmodied 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.
• If operating a power tools 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.
Personal Safety
• 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 inuence of
drugs, alcohol or medication. A moment of inattention while operating power tools may
result in serious personal injury.
• 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.

SAFETY INFORMATION
• 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 nger on the switch or energizing 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 jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewelry 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 dust devices can
reduce dust related hazards.
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 more safely 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 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.
• 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,
breakage of parts and any other condition that may affect the power tool's
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, 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.

SAFETY INFORMATION
Service
• Have your power tool serviced by a qualied repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
Specic Safety Rules for Impact Wrench
• Hold power tool by insulated gripping surfaces, when performing an operation
where the fastener may contact hidden wiring or its own cord. Fasteners with a
“live” wire may make exposed metal parts of the tool live and could give the operator an
electric shock.
• Do not use the power tool with a damaged cord. Do not touch the damaged
cord and pull the plug from the outlet when the cord is damaged while working.
Damaged cords increase the risk of an electric shock.
• Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held
more secure than by hand.
• Always wait until the power tool has come to a complete stop before placing it
down. The tool insert can jam and lead to loss of control over the power tool.
PREPARATION
Before attempting to use the impact wrench, familiarize yourself with all of its operating
features and safety requirements.

tent fastening torque and/or damage
to the bolt or nut.
a. To install the socket, push it onto
the 1/2-inch square drive of the
tool until it locks into place.

3. Installing Fasteners
NOTICE: Always keep the impact wrench at a right angle to the fastener to avoid
damaging the fastener head.
TO FASTEN:
a. Start threading the fastener by hand onto or into its threaded counterpart (e.g., nut
onto bolt, or bolt into nut or threaded hole).
b. With the proper impact socket securely mounted to the wrench, slide the impact
socket onto the nut or bolt head.
c. Firmly hold the tool and depress the switch at “F”. The impact socket will turn the
fastener and impacting will begin once the fastener encounters resistance.
WARNING: Do not over-tighten, as the force of the impact wrench can break the
fastener and cause injury.
TO LOOSEN:
a. With the proper impact socket securely mounted to the wrench, slide the impact
socket onto the bolt head.
b. Firmly hold the tool and depress the switch at “R”. The tool will start to impact
immediately.
c. Once the fastener has "broken loose", it will start to unthread. Be careful that you
do not allow a fastener to spin freely once it is no longer engaged with its threaded
counterpart, as it may be thrown out of the socket.
