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

4. Grounded tools must be plugged into an outlet properly installed and grounded

in accordance with all codes and ordinances. Never remove the grounding

prong or modify the plug in any way. Do not use any adapter plugs. Check

with a qualified electrician if you are in doubt as to whether the outlet is properly

grounded. If the tools should electrically malfunction or break down, grounding

provides a low resistance path to carry electricity away from the user.

5. Double insulated tools are equipped with a polarized plug (one blade is wider

than the other). This plug will fit in a polarized outlet only one way. If the plug

does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a

qualified electrician to install a polarized outlet. Do not change the plug in

any way. Double insulation eliminates the need for the three wire grounded

power cord and grounded power supply system.

6. 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.

7. Do not expose power tools to rain or wet conditions. Water entering a power

tool will increase the risk of electric shock.

8. Do not abuse the Power Cord. Never use the Power Cord to carry the tools or

pull the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp

edges, or moving parts. Replace damaged Power Cords immediately. Damaged

Power Cords increase the risk of electric shock.

9. When operating a power tool outside, use an outdoor extension cord marked

“W-A” or “W”. These extension cords are rated for outdoor use, and reduce the

risk of electric shock.

PERSONAL SAFETY

10. 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 94855 PAGE 3

which may ignite the dust or fumes.

11. 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.

12. Avoid accidental starting. Be sure the Power Switch is off before plugging in.

Carrying power tools with your finger on the Power Switch, or plugging in power

tools with the Power Switch on, invites accidents.

13. Remove adjusting keys or wrenches before turning the power tool on.

A wrench or a key that is left attached to a rotating part of the power tool may result

in personal injury.

14. Do not overreach. Keep proper footing and balance at all times. Proper footing

and balance enables better control of the power tool in unexpected situations.

15. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety

shoes, hard hat, or hearing protection must be used for appropriate conditions.

TOOL USE AND CARE

16. 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.

17. 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.

18. Do not use the power tool if the Power Switch does not turn it on or off. Any

tool that cannot be controlled with the Power Switch is dangerous and must be

replaced.

19. Disconnect the Power Cord Plug from the power source before making any

adjustments, changing accessories, or storing the tool. Such preventive safety

measures reduce the risk of starting the tool accidentally.

20. Store idle tools out of reach of children and other untrained persons. Tools

are dangerous in the hands of untrained users.

21. Maintain tools with care. Keep cutting tools sharp and clean. Properly

maintained tools with a sharp cutting edge 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 94855 PAGE 4

22. 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.

23. 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

24. Tool service must be performed only by qualified repair personnel. Service or

maintenance performed by unqualified personnel could result in a risk of injury.

25. 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 instructionsmay

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 Wrench 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 the Impact Wrench. These carry important

information. If unreadable or missing, contact Harbor Freight Tools for a replacement.

3. When using the Impact Wrench, always maintain a firm grip on the tool with

both hands.

4. Do not use the ImpactWrench or Charger (48) if it has been dropped,damaged,

left outdoors, or immersed in liquid.

5. Do not charge the Battery (30) when the temperature is below 50 degrees

Fahrenheit or above 104 degrees Fahrenheit.

6. Do not shake, drop, or strike the Battery (30).

SKU 94855 PAGE 5

7. To avoid electrical shock, do not pull or carry the Charger (48) by its Power

Cord or pull the Power Cord around sharp corners or edges. Do not unplug the

Charger by pulling on the Power Cord. Keep the Power Cord away from heated

surfaces.

8. To avoid electrical shock,do not handle the Charger (48), its Power Cord Plug,

or the Impact Wrench with wet hands.

9. Keep the Handle of the Impact Wrench dry, clean, free from oil and grease.

10. Avoid unintentional starting. Make sure you are prepared to begin work before

turning on the Impact Wrench.

11. Never leave the Charger (48) unattended when it is plugged into an electrical

outlet. Make sure to unplug it from its electrical outlet before leaving.

12. Always turn off the Impact Wrench and unplug the Charger (48) from its

electrical outlet before changing accessories or performing any inspection,

maintenance, or cleaning procedures.

13. Always switch to a fresh Battery (30) 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 even after tool

performance is decreasing. Never attempt to discharge a tool’s Battery by continuing

to pull the tool’s trigger. When tool performance begins to diminish stop the tool,

recharge the Battery, and use the fresh Battery for optimal performance.

14. Battery (30) 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.

15. Never burn the Battery, as it can explode in a fire. Do not charge the Impact

Wrench if it has a leaking Battery. Contact local solid waste authorities for instructions

on correct disposal or recycling of the Battery.

WARNING: This product contains or, when used, produces a chemical known to

the State of California to cause cancer and birth defects or other

reproductive harm. (California Health & Safety Code 25249.5, et seq.)

16. WARNING! People with 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.

GROUNDING

WARNING!

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 elec-

tric shock. (See Figure A.)

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 Figure A.)

3. Your 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 Figure A.)

FIGURE A

SKU 94855 PAGE 7

Improperly connecting the grounding wire can result in the risk of 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 in-

stalled by a qualified electrician.

FIGURE B

SKU 94855 PAGE 8

DOUBLE INSULATED TOOLS:TOOLS WITH TWO PRONG PLUGS

4. 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 Figure B.)

5. Double insulated tools may be used in either of the 120 volt outlets shown in the

following illustration. (See Figure B.)

EXTENSION CORDS

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 Figure C, next page.)

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 Figure C.)

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 Figure C.)

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 Figure C.)

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.

7. Make sure your 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 your extension cords from sharp objects, excessive heat, and damp or

wet areas.
