POWER TOOL SAFETY
WARNING:Read all safety warnings and instructions.
Failure to follow the warnings and instructions may result
in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
2. 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.
3. Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
WARNING:To avoid electrical hazards, fire hazards or
damage to the tool, use proper circuit protection.
This tool is wired at the factory for 120V AC operation.
It must be connected to a 20V AC, 15 A circuit that is
protected by a time-delayed fuse or circuit breaker. To
avoid shock or fire, replace power cord immediately if it is
worn, cut or damaged in any way.
WARNING:Ventilation openings in batteries and
chargers must always be open to allow cooling air to
circulate freely. Air vents that are blocked, restricted or
covered may result in the battery or charger overheating.
Overheating may lead to damage to the tool or cause a
fire resulting in possible serious injury.
1. 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.
2. 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.
3. DO NOT expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
4. 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.
5. 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.
6. If operating a power tool in a damp location is
unavoidable, use a residual current device (RCD)
protected supply. Use of a ground fault circuit
interrupter (GFCI) reduces the risk of electric shock.
PERSONAL SAFETY
1. 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.
2. 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.
3. 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.
4. 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.
5. DO NOT overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
6. 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.
7. 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.
8. Hold power tool by insulated gripping surfaces,
when performing an operation where the fastener
may contact hidden wiring or its own cord. Fasteners
contacting a “live” wire may make exposed metal parts
of the power tool “live” and could give the operator an
electric shock.
POWER TOOL USE AND CARE
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.

7. 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.
BATTERY TOOL USE AND CARE
1. Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type of
battery pack may create a risk of fire when used with
another battery pack.
2. Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
3. When battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys, nails,
screws or other small metal objects that can make a
connection from one terminal to another. Shorting the
battery terminals together may cause burns or a fire.
4. Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, flush with water. If liquid contacts eyes, seek
medical help. Liquid ejected from the battery may
cause irritation or burns.
SERVICE
DO NOT disassemble the Impact Wrench. 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.

used with an Impact Wrench. They may shatter and
possibly cause serious injury.
6. Before each use, check the Impact sockets and
accessories for excessive wear or cracks. Worn or
damaged sockets or accessories may shatter and
possibly cause serious injury. Worn accessories may
allow the socket to come off during operation of the
Impact Wrench.
7. After installing any accessory in the hex drive, pull
outward on the accessory to ensure it is properly
installed and cannot be pulled out of the hex drive.
8. Never use the Impact Wrench as a torque wrench.
Always use a torque wrench to adjust the fastener to
the specified torque.
9. Keep the Impact Wrench handle and body clean and
free of oil and grease. Always use a clean dry cloth
when cleaning. DO NOT use solvents, brake fluid,
gasoline or other petroleum products to clean the tool.
They will damage the tool.
10. DO NOT wear neckties or loose clothing.
11. When wearing gloves, they must be tight fitting and
slip resistant type. Leather gloves offer the best
protection.
12. Always use two hands when operating the Impact
Wrench. Use one hand on the handle and the other on
the front of the tool body.
13. Never place your hand so it is touching the socket
or accessory when the tool is turned ON. Your hand
could be seriously injured.
14. Always remove the battery from the tool before installing

unexpected shifting of the components.
WARNING:WEAR A DUSK MASK THAT IS
DESIGNED TO BE USED WHEN OPERATING A POWER
TOOL IN A DUSTY ENVIROMENT.
Dust that is created by power sanding, sawing, grinding,
drilling, and other construction activities may contain
chemicals that are known to cause cancer, birth defects,
or other genetic abnormalities. These chemicals include:
• Lead from lead-based paints
• Crystalline silica from bricks, cement, and other
masonry products
• Arsenic and chromium from chemically treated lumber
The level of risk from exposure to these chemicals varies,
according to how often this type of work is performed. In
order to reduce exposure to these chemicals, work in a
well-ventilated area, and use approved safety equipment,
such as dust mask that is specifically designed to filter
out microscopic particles.
IMPORTANT SAFETY INSTRUCTIONS
The warnings, precautions, and instructions discussed
