Introduction
The unit for which this Maintenance Log is provided conforms to U.S. E.P.A. Regulations for
Noise Emissions, applicable to Portable Air Compressors.
The purpose of this book is to provide (1) the Maintenance Performance Schedule for all
required noise emission controls and (2) space so that the purchaser or owner can record what
maintenance was done, by whom, where and when. The Maintenance Schedule and detailed
instructions on the maintenance items are given on following page.
Maintenance Schedule
A. Compressed Air Leaks
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.
C. Acoustic Materials
In daily inspections, observe these materials. Maintain all acoustic material as nearly as
possible in its original condition. Repair or replace all sections that have: 1) sustained damage,
2) have partially separated from panels to which they were attached, 3) are missing, or have
otherwise deteriorated due to severe operating or storage conditions.
