Safety Warnings and Precautions
WARNING: When using tool, basic safety precautions should always be followed to
reduce the risk of personal injury and damage to equipment.
Read all instructions before using this tool!
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 tools 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. Do not force tool. It will do the job better and more safely at the rate for which it was
intended. Do not use inappropriate attachments in an attempt to exceed the tool
capacity.
6. 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. Do not modify this tool and do not use this tool for a purpose for which
it was not intended.
7. 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. Use eye and ear protection. Always wear ANSI approved impact safety goggles.
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.
9. Do not overreach. Keep proper footing and balance at all times. Do not reach over or
across running machines or air hoses.
10. 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.
11. Disconnect air supply. Disconnect air hose when not in use.
12. Remove adjusting keys and wrenches. Check that adjusting wrenches are
removed from the tool or machine work surface before plugging it in.
13. Avoid unintentional starting. Be sure the Sliding Knob (#4) is not twisted in the on
position when not in use and before plugging in.
14. Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
15. 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.
16. Guard against electric shock. Prevent body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerator enclosures.
17. 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.
18. Do not operate tool if under the influence of alcohol or drugs. Read warning
labels on prescriptions to determine if your judgment or reflexes are impaired while
taking drugs. If there is any doubt, do not operate the tool.
19. 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 tool without heating
up. Otherwise, the extension cord could melt and catch fire, or cause electrical
damage to the tool. Check your compressor’s manual for the appropriate size cord.
20. Maintenance. For your safety, maintenance should be performed regularly by a
qualified technician.
21. Compressed air only. Never use combustible gases as a power source.
22. Read and adhere to all warnings and instructions provided in the instruction manual of
the air compressor being used to power the Air Die Grinder.
