General Safety Rules
WARNING! Read all instructions
Failure to follow all instructions listed below may result in electric shock,
fire, and/or serious injury. The term “power tool” in all of the warnings listed
below refers to your mains-operated (corded) power tool or battery-operated
(cordless) power tool.
SAVE THESE INSTRUCTIONS
1.
Work area safety
a. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b. 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.
c. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2.
Electrical safety
a. 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.
b. 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.
c. Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
d. 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.
3.
Personal safety
a. 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.
b. Use safety equipment. Always wear eye protection. Safety equipment
such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c. 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.
SKU 65817
For technical questions, please call 1-800-444-3353.
Page 4
d. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
e. 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.
4.
Power tool use and care
a. 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.
b. Do not use the power tool if the Trigger does not turn it on and off. Any power
tool that cannot be controlled with the Trigger is dangerous and must be repaired.
c. Disconnect 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.
d. 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.
e. Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tools
operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
f. Keep tools clean. Properly maintained tools are less likely to bind and are
easier to control.
g. Use the power tool, accessories and sockets etc., in accordance with these
instructions and in the manner intended for the particular type of power tool,
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.
5.
Service
a. 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.
Specific Safety Rules
1.
Maintain labels and nameplates on the tool. These carry important safety information. If unreadable or missing, contact Harbor Freight Tools for a replacement.
2.
Avoid unintentional starting. Prepare to begin work before turning on the tool.
SKU 65817
For technical questions, please call 1-800-444-3353.
Page 5
3.
Do not lay the tool down until it has come to a complete stop. Moving parts can
grab the surface and pull the tool out of your control.
4.
When using a handheld power tool, maintain a firm grip on the tool with both
hands to resist starting torque.
5.
Do not leave the tool unattended when it is plugged into an electrical outlet. Turn
off the tool, and unplug it from its electrical outlet before leaving.
6.
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.
7.
The battery charger gets hot during use. The charger’s heat can build
up to unsafe levels and create a fire hazard if it does not receive
adequate ventilation, due to an electrical fault, or if it is used in a hot
environment.
Do not place the charger on a flammable surface. Do not obstruct any vents on
the charger. Especially avoid placing the charger on carpets and rugs; they
are not only flammable, but they also obstruct vents under the charger.
Place the charger on a stable, solid, nonflammable surface (such as a stable
metal workbench or concrete floor) at least 1 foot away from all flammable objects, such as drapes or walls. Keep a fire extinguisher and a smoke detector in
the area. Frequently monitor the charger and battery during use.
8.
This product is not a toy. Keep it out of reach of children.
9.
People with pacemakers should consult their physician(s) before use. Electromagnetic fields in close proximity to heart pacemaker could cause pacemaker
interference or pacemaker failure. In addition, people with pacemakers should:
• Avoid operating alone.
• Do not use with power switch locked on.
• Properly maintain and inspect to avoid electrical shock.
• Any power cord must be properly grounded. Ground Fault Circuit Interrupter
(GFCI) should also be implemented – it prevents sustained electrical shock.
10.
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 or other masonry 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.)

Only use the included battery to power the Inpact Wrench. Never attempt to use
a battery from any other powered tool in place of the battery for this tool.
12.
The warnings, precautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur. It must be
understood by the operator that common sense and caution are factors which
cannot be built into this product, but must be supplied by the operator.
Save these instructions.
Grounding
WARNING
Improperly connecting the grounding wire can result in
electric shock.
Check with a qualified electrician if you are in doubt as to
whether the outlet is properly grounded. Do not modify
the power cord plug provided with the tool. Never remove
the grounding prong from the plug. Do not use the tool if
the power cord or plug is damaged. If damaged, have it
repaired by a service facility before use. If the plug will not
fit the outlet, have a proper outlet installed by a qualified
electrician.
Grounded Tools: Tools with Three Prong Plugs
1.
Tools marked with “Grounding Required” have a three wire cord and three prong
grounding plug. The plug must be connected to a properly grounded outlet. If
the tool should electrically malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user, reducing the risk of electric
shock. (See 3-Prong Plug and Outlet.)
2.
The grounding prong in the plug is connected through the green wire inside the
cord to the grounding system in the tool. The green wire in the cord must be the
only wire connected to the tool’s grounding system and must never be attached
to an electrically “live” terminal. (See 3-Prong Plug and Outlet.)
3.
The tool must be plugged into an appropriate outlet, properly installed and
grounded in accordance with all codes and ordinances. The plug and outlet
should look like those in the following illustration. (See 3-Prong Plug and Outlet.)
SKU 65817
For technical questions, please call 1-800-444-3353.
Page 7
3-Prong Plug and Outlet
Outlets for 2-Prong Plug
Double Insulated Tools: Tools with Two Prong Plugs
1.
Tools marked “Double Insulated” do not require grounding. They have a special
double insulation system which satisfies OSHA requirements and complies with
the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association, and the National Electrical Code.
(See Outlets for 2-Prong Plug.)
2.
Double insulated tools may be used in either of the 120 volt outlets shown in the
preceding illustration. (See Outlets for 2-Prong Plug.)
Extension Cords
1.
Grounded tools require a three wire extension cord. Double Insulated tools can
use either a two or three wire extension cord.
2.
As the distance from the supply outlet increases, you must use a heavier gauge
extension cord. Using extension cords with inadequately sized wire causes a
serious drop in voltage, resulting in loss of power and possible tool damage.
(See Table A.)
3.
The smaller the gauge number of the wire, the greater the capacity of the cord.
For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Table A.)
4.
When using more than one extension cord to make up the total length, make
sure each cord contains at least the minimum wire size required. (See Table A.)
5.
If you are using one extension cord for more than one tool, add the nameplate
amperes and use the sum to determine the required minimum cord size.
(See Table A.)
6.
If you are using an extension cord outdoors, make sure it is marked with the suffix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
SKU 65817
For technical questions, please call 1-800-444-3353.
Page 8
7.
Make sure the extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.
8.
Protect the extension cords from sharp objects, excessive heat, and damp or wet
areas.
