•

Particles blown by compressed air are hazardous. DO NOT exceed 15 psi (103 kPa) nozzle pressure

when drying parts with compressed air. Use a maximum of 30 psi (207 kPa) when cleaning

components. DO NOT direct compressed air against human skin. To prevent injury, user must wear

protective goggles or face shield. Make sure air stream is directed away from user and other

personnel in the area. Failure to follow this warning may result in injury to personnel.

•
