SAFETY WARNING & CAUTIONS

WARNING: 

When using pneumatic equipment, basic safety precautions should always be 

followed to reduce the risk of personal injury and hazards due to over pressurization.

Do not use tools in damp, wet, or poorly lit  

 

 

locations. Don’t expose to rain. Keep work area well lit. Do not use electrically powered air    

 

compressors in the presence of flammable gases or liquids.

3.

 Children must never be allowed in the work area. Do not let them  

 

handle machines, tools, or hoses.

4.

which it was not intended.
