SAVETHESE INSTRUCTIONS
WORK AREA
1. Keep your work area clean and well lit. Cluttered benches and 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
dustor fumes.

3. Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from debris
such as chips and sparks. Provide barriers or shields as needed.
ELECTRICAL SAFETY
1. 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.
2. Do not expose power tools to rain or wet conditions. Waterenteringapowertool will
increase 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 tired or under the influence of drugs,
alcohol, or medication. A moment of inattention while operating power tools may
result in serious personal injury.
SKU 92472 For technical questions, please call 1-800-444-3353 PAGE 3
2. 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.
3. Avoid accidental starting. Be sure theTrigger (34) is released before plugging in.
Carrying power tools with your finger on the Trigger, or plugging in power tools with the
Trigger depressed, invites accidents.
4. Remove adjusting keys or wrenches before turning the power tool on. Awrench or
a key that is 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. Properfooting and
balance enables better control of the power tool in unexpected situations.
6. Use safety equipment. Always wear ANSI approved safety glasses underneath a full
face safety shield. Dust mask, nonskid safety shoes, hard hat, or hearing protection
must be used for appropriate conditions.
7. Use clamps (not included) or other practical ways 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.

TOOL USE AND CARE
1. Do not force the 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.
2. Do not use the power tool if theTrigger (34) does not turn it on or off. Any tool that
cannot be controlled with the Trigger is dangerous and must be replaced.
3. Disconnect the power tool from its Battery (40) before making any adjustments,
changing accessories, or storing the tool. Such preventive safety measures reduce
the risk of starting the tool accidentally.
4. Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
5. Maintain tools with care. Keep tools dry and clean. Properly maintained tools are
less likely to bind and are easier to control. Do not use a damaged tool. Tag damaged
tools “Do not use” until repaired.
SKU 92472 For technical questions, please call 1-800-444-3353 PAGE 4
6. Check for misalignment or binding of moving parts, breakage of parts, and any
other condition that may affect the tool’s operation. If damaged, have the tool
serviced before using. Many accidents are caused by poorly maintained tools.
7. 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
1. Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
2. When servicing a tool, use only identical replacement parts. Follow instructions in
the “Inspection, Maintenance, And Cleaning” section of this manual. Use of
unauthorized parts or failure to follow maintenance instructions may create a risk of
electric shock or injury.
SPECIFIC SAFETY RULES
1. Maintain a safe working environment. Keep the work area well lit. Make sure there
is adequate surrounding workspace. Always keep the work area free of

obstructions, grease, oil, trash, and other debris. Do not use the Impact Driver in areas
near flammable chemicals, dusts, and vapors. Do not use this product in a damp or wet
location.
2. Maintain labels and nameplates on this product. These carry important information.
If unreadable or missing, contact Harbor FreightTools for a replacement.
3. When using the Impact Driver, always maintain a firm grip on the tool with both
hands.
4. Hold the tool by its insulated gripping surfaces when performing an operation
where the Impact Driver may contact hidden wiring. Contact with a “live” wire will
make exposed metal parts of the Impact Driver “live” and shock the operator.
5. Do not use the Impact Driver or Charger (46) if it has been dropped, damaged, left
outdoors, or immersed in liquid.
6. To avoid electrical shock, do not handle the Charger (46), its Power Cord Plug, or
the Impact Driver with wet hands.
7. Keep the Handle of the Impact Driver dry, clean, and free from oil and grease.
8. Always turn off the Impact Driver and unplug the Charger (46) from its electrical
outlet before changing accessories or performing any inspection, maintenance,
or cleaning procedures.
9. Avoid unintentional starting. Makesure you areprepared tobegin workbeforeturning
on the Impact Driver.
10.To avoid electrical shock,do not pull or carry the Charger (46) by its Power Cord.
11.Never leave the Charger (46) unattended when itis plugged into an electrical outlet.
Make sure to unplug it from its electrical outlet before leaving.
12.Proper Battery Care: Battery (40) leakage may occur under extreme usage or
temperature conditions. If Battery fluid comes in contact with skin, wash with soap and
water and rinse with lemon juice and vinegar. If the fluid comes into contact with the
eyes, flush with water for several minutes and contact a doctor immediately. Never burn
the Battery, as it can explode in a fire. Do not charge the Impact Driver with a leaking
Battery. Contact local solid waste authorities for instructions on correct disposal or
recycling of the Battery.

15. WARNING! People with pacemakers should consult their physician(s) before
using this product. Electromagnetic fields in close proximity to a heart pacemaker could
cause interference or failure of the pacemaker. In addition, people with pacemakers
should adhere to the following: Avoid operating power tools alone. Don’t use a power
tool with the power switch (Trigger) locked on. If powered via a power cord be certain
that the tool is properly grounded. A ground fault interrupt (GFCI) system is also a good
precaution. This inexpensive device is a good safety measure because it prevents a
sustained electrical shock. Properly maintain and inspect all tools before use to avoid
electrical shock.
16. WARNING! The warnings, precautions,andinstructionsdiscussed in thismanual
cannot cover all possible conditions and situations that may occur. The operator must
understand that common sense and caution are factors which cannot be built into this
product, but must be supplied by the operator.
14. WARNING! Some dust created by power sanding, sawing, grinding, drilling, and
otherconstructionactivities, containchemicals known(tothe Stateof California)tocause
cancer, birth defects or other reproductive harm. Some examples of these chemicals
are:lead from lead-basedpaints,crystallinesilicafrombricksandcementorothermasonry
products, 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 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.
(California Health & Safety Code 25249.5, et seq.)
13.Always switch to a fresh Battery (40) when tool performance begins to diminish.
Severe heat is most destructive to a Battery. The more heat generated, the faster the
Battery loses power. A Battery that gets too hot can be permanently damaged. Never
over-discharge a Battery by using the tool while tool performance is decreasing. Never
attemptto discharge atool’s Battery bycontinuingto pullthe toolTrigger (34). When tool
performance begins to diminish, stop the tool, recharge the Battery, and use the fresh
Batteryfor optimalperformance.
