Fault Finding
Introduction
Troubleshooting for a portable air compressor is an organized study of a particular problem or
series of problems and a planned method of procedure for investigation and correction. The
troubleshooting chart that follows includes some of the problems that an operator may
encounter during the operation of a portable compressor.
The chart does not attempt to list all of the troubles that may occur, nor does it attempt to give
all of the answers for correction of the problems. The chart does give those problems that are
most apt to occur. To use the troubleshooting chart:
A. Find the “complaint” depicted as a bold heading.
B. Follow down that column to find the potential cause or causes. The causes are
listed in order (1, 2, 3 etc.) to suggest an order to follow in troubleshooting.
Action Plan
A. Think Before Acting
Study the problem thoroughly and ask yourself these questions:
1. What were the warning signals that preceded the trouble?
2. Has a similar trouble occurred before?
3. What previous maintenance work has been done?
4. If the compressor will still operate, is it safe to continue operating it to make
further checks?
B. Do the Simplest Things First
Most troubles are simple and easily corrected. For example, most complaints are
“low capacity” which may be caused by too low an engine speed or “compressor over-heats”
which may be caused by low oil level.
Always check the easiest and most obvious things first; following this simple rule will save time
and trouble.

Diagram Schematic found in Parts List Section.
