Safety Warnings and Precautions

WARNING: When using product, basic safety precautions should always be followed to
reduce the risk of personal injury and damage to equipment.

Read all instructions before using this product!

1. Keep work area clean. Cluttered areas invite injuries.

2. Observe work area conditions. Do not use machines or power tools in damp or wet

locations. Don’t expose to rain. Keep work area well lighted. Do not use electrically powered
compressors in the presence of flammable gases or liquids.

3. Keep children away. Children must never be allowed in the work area. Do not let them

handle machines, tools, extension cords, or air hoses.

4. Store idle equipment. When not in use, tools must be stored in a dry location to inhibit rust.

Always lock up tools and keep out of reach of children.

5. Use the right tool for the job. Do not attempt to force a small tool or attachment to do the

work of a larger industrial tool. There are certain applications for which this tool was designed.
It will do the job better and more safely at the rate for which it was intended. Do not modify this
tool and do not use this tool for a purpose for which it was not intended.

6. Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving parts.

Protective, electrically nonconductive clothes and nonskid footwear are recommended when
working. Wear restrictive hair covering to contain long hair.

8. Do not overreach. Keep proper footing and balance at all times. Do not reach over or across

running machines or air hoses.

9. Maintain tools with care. Keep tools clean for better and safer performance. Follow

instructions for lubricating and changing accessories. Inspect tool cords and air hoses
periodically and, if damaged, have them repaired by an authorized technician. The handles
must be kept clean, dry, and free from oil and grease at all times.

10. Disconnect air supply. Disconnect air hose when not in use.

11. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches are

removed from the tool or machine work surface before plugging it in.

12. Avoid unintentional starting. Be sure the trigger is released when not in use and before

plugging in. Do not carry any tool with your finger on the trigger, whether it is plugged in or not.

13. Stay alert. Watch what you are doing, use common sense. Do not operate any tool when you

are tired.

14. Check for damaged parts. Before using any tool, any part that appears damaged should be

carefully checked to determine that it will operate properly and perform its intended function.
Check for alignment and binding of moving parts; any broken parts or mounting fixtures; and
any other condition that may affect proper operation. Any part that is damaged should be
properly repaired or replaced by a qualified technician. Do not use the tool if any switch does
not turn On and Off properly.

Use eye and ear protection. Always wear ANSI approved impact safety goggles
and hearing protection. Wear a full face shield if you are producing metal filings or
wood chips. Wear an ANSI approved dust mask or respirator when working around
metal, wood, and chemical dusts and mists.

15. Guard against electric shock. Prevent body contact with grounded surfaces such as pipes,

radiators, ranges, and refrigerator enclosures.

16. Replacement parts and accessories. When servicing, use only identical replacement parts.

Use of any other parts will void the warranty. Only use accessories intended for use with this
tool. Approved accessories are available from Harbor Freight Tools.

17. Do not operate tool if under the influence of alcohol or drugs. Read warning labels if

taking prescription medicine to determine if your judgement or reflexes are impaired while
taking drugs. If there is any doubt, do not operate the Wrench.

18. Use proper size and type extension cord. If an extension cord is required, it must be of the

proper size and type to supply the correct current to the compressor without heating up.
Otherwise, the extension cord could melt and catch fire, or cause electrical damage to the
compressor. Check your air compressor’s manual for the appropriate size cord.

19. Maintenance. For your safety, maintenance should be performed regularly by a qualified

technician.

20. Compressed air only. Never use combustible gas as a power source.

21. This Impact Wrench should only be used with impact sockets and extensions. Using

any other accessories can cause the accessories to break, causing permanent damage to
the unit and severe injury to the operator, property or bystanders.
