ELECTRICAL SAFETY
GENERAL SAFETY WARNINGS
WEAR A DUST MASK THAT IS DESIGNED TO BE USED WHEN
OPERATING A POWER TOOL IN A DUSTY ENVIRONMENT.
WARNING: 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 a dust mask that is specifically designed to filter out
microscopic particles.
!
WARNING: To avoid electrical hazards, fire hazards or damage to the
tool, use proper circuit protection.
This tool is wired at the factory for 120 V AC operation. It must be
connected to a 120 V 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.

5
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
Keep work area clean and well lit.
Cluttered or 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 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.
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
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.
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.
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 energising 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.
POWER TOOL SAFETY
!

PERSONAL SAFETY –cont’d
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 jewellery. Keep your hair,
clothing and gloves away from moving
parts. Loose clothes, jewellery 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 collection 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 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 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 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.

WARNING: Know your impact
wrench. Do not plug the tool into the
power source until you have read and
understand this Instruction Manual.
Learn the tool’s applications and
limitations, as well as the specific
potential hazards related to this tool.
Following this rule will reduce the risk of
electric shock, fire or serious injury.
Always wear eye protection.
Any power tool can throw
foreign objects into your eyes
and cause permanent eye
damage. ALWAYS wear safety goggles
(not glasses) that comply with ANSI safety
standard Z87.1. Everyday glasses have
only impact resistant lenses. They ARE
NOT safety glasses.
WARNING: Glasses or goggles
not in compliance with ANSI Z87.1
could cause serious injury when they
break.
Always use hearing protection when
operating the impact wrench.
Use only impact sockets and accessories
that are designed for use with an impact
wrench. Do not use chrome plated sockets
and accessories. Chrome plated sockets
and accessories are designed for hand
use only and MUST NOT be used with an
impact wrench. They may shatter and
possibly cause serious injury.
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.
WARNING: Always use a torque
wrench to verify the torque being delivered
each time the impact wrench torque setting
is changed. This will prevent over or under
tightened fasteners.
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.
Do not wear neckties or loose clothing.
When wearing gloves, they must be tight
fitting and slip resistant type. Leather
gloves offer the best protection.
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.
Never place your hand so it is touching the
socket or accessory when the tool is
turned ON. Your hand could be seriously
injured.
Always remove the plug from the power
source before installing or removing any
socket or accessory.
Be ready for components to shift when
removing any fastener. The speed of the
fastener removal could cause unexpected
shifting of the components.

WARNING: This impact wrench is
calibrated for tightening standard nuts
used on automotive wheel nuts. Using the
torque settings to indicate the torque being
applied to fasteners with finer or coarser
threads will result in the fastener being
either over or under tightened. Always use
a torque wrench to verify the torque being
delivered to the fastener.
WARNING: Only use the pre-set
torque value when tightening right hand
threads. It DOES NOT work when using
the impact wrench to tighten left hand
threaded fasteners.
WARNING: The pre-set torque value
DOES NOT work when using the impact
wrench to remove fasteners. When used in
the REVERSE direction, full torque will be
applied to the fastener.
WARNING: Keep the extension
cord clear of the work area. Position the
cord so that it will not get caught on the
workpiece, a tool, or any other obstruction
while the power tool is in use.
If an extension cord is used with this
impact wrench, verify that it is in good
condition. When using an extension cord,
be sure to use one that is heavy enough to
carry the current that the tool will draw. An
undersized cord will cause a drop in line
voltage, which will result in a loss of power
and overheating.
The following table shows the correct size
to use according to cord length and the
amperage rating that is listed ton the tool's
nameplate. When in doubt, use the next
heavier gauge. The smaller the gauge
number, the heavier the cord.
Verify that the extension cord is properly
wired and in good condition. Replace a
damaged extension cord immediately, or
have it repaired by a qualified electrician
before using it. Keep the extension cord
away from sharp objects, excessive heat,
and damp or wet areas.
Use a separate electrical circuit for power
tools. This circuit must consist of not less
than 14 gauge wire, and should be
protected by either a 15 A time-delayed
fuse or a circuit breaker. Before connecting
the power tool to the outlet, verify that the
switch is in the OFF position, and that the
voltage of the power source is the same as
the voltage that is indicated on the tool's
nameplate. Running this impact wrench at
lower voltage will damage the motor.
