Troubleshooting
Introduction
Troubleshooting for a light tower 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.
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 likely to occur.
Find the complaint depicted as a bold
heading.
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
Think Before Acting
Study the problem thoroughly and ask
yourself these questions:
1. What were the warning signals (if any)
that preceded the trouble?
2. Has a similar trouble occurred before?
3. What previous maintenance work has
been done?
4. If the alternator will still operate, is it safe
to continue operating it to make further
checks?
Do The Simplest Things First
Most troubles are simple and easily
corrected. Always check the easiest and
most obvious things first; Following this
simple rule will save time and trouble.
Double Check Before Disassembly
The source of most troubles can be traced
not to one component alone, but to the
relationship of one component with another.
Too often, a machine can be partially
disassembled in search of the cause of a
certain trouble and all evidence is destroyed
during disassembly. Check again to be sure
an easy solution to the problem has not been
overlooked.
Find And Correct Basic Cause
After a mechanical failure has been
corrected, be sure to locate and correct the
cause of the trouble so the same failure will
not be repeated.
