Noise Emissions, applicable to Portable Air Compressors.
The purpose of this book is to provide (1) the Maintenance Performance Schedule below for

what maintenance was done, by whom, where and when. Detailed instructions on the
maintenance items below are given on following page.
Maintenance Schedule

Correct all compressed air leaks during the first shutdown period after discovery. If severe
enough to cause serious noise problems and efficiency loss, shut down immediately and
correct the leak(s).
B. Safety and Control Systems
Repair or replace all safety and control systems or circuits as malfunction occurs. No
compressor should be operated with either system bypassed, disabled, or nonfunctional.

possible in its original condition. Repair or replace all sections that have: 1) sustained damage,

otherwise deteriorated due to severe operating or storage conditions.
