Safety Warnings and Precautions
WARNING: When using tools, 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 lit. Do not use electrically powered
tools in the presence of ammable 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.
7. Use eye and ear protection. Always wear ANSI approved impact safety glasses under
a full face shield while working. Wear an ANSI approved dust mask or respirator when
working around metal, wood, and chemical dusts and mists.
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 connecting the tool.
12. Avoid unintentional starting. Be sure the trigger is released when not in use and be-
fore connecting to the air source. Do not carry any tool with your nger on the trigger,
whether it is connected 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 xtures; and any other condition that may affect proper operation. Any part
that is damaged should be properly repaired or replaced by a qualied technician. Do
not use the tool if the trigger does not operate 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

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 compressor without heating
up. Otherwise, the extension cord could melt and catch re, or cause electrical damage
to the compressor. Check your air compressor’s manual for the appropriate size cord.
20. Maintenance. For your safety, maintenance should be performed regularly by a quali-
ed technician.
