Trouble shooting 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 cor-
rection.
The trouble shooting chart
that follows includes some of the
problems that an operator may en-
counter
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 an-
swers for correction
of the prob-
lems.
The chart does give those
problems that are most apt to occur.
To use the trouble shooting chart:
A.
Find the "complaint" in the top
horizontal line.
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 be-
fore?
(3)
What previous maintenance work
has been done?
(4)
If the compressor
will still oper-
ate, is it safe to continue operat-
ing it to make further checks?
B.
Do
The Simplest Things FIrst
Most troubles are simple and easily cor-
rected.
For example, most complaints
are "low capacity" which may be caused
by too Iowan
engine speed or "com-
pressor
over-
heats"
which
may be
caused by low oil level.
Always check the easiest and most ob-
vious things first; following this simple
rule will save time and trouble.
Note:
For trouble shooting
electrical
problems, refer to the Wiring Diagram
Schematic
found in Section

B.
Follow down that column
to
find
the potential
cause
or

The numbers (1,2,3
