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 non-conductive clothes and non-skid 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.

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. Use clean, dry regulated, compressed air at 90 PSI. Never

use oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power source for this tool.
