General information on troubleshooting

The aim of troubleshooting is to pinpoint the basic cause of the failure, to carry out repairs swiftly, and to prevent reoccurrence of the failure. When carrying out troubleshooting, an important point is of course to understand the structure and function. However, a short cut to effective troubleshooting is to ask the operator various questions to form some idea of possible causes of the failure that would produce the reported symptoms.

1. When carrying out troubleshooting, do not hurry to disassemble the components.
If components are disassembled immediately after any failure occurs: • Parts that have no connection with the failure or other unnecessary parts will be disassembled.
• It will become impossible to find the cause of the failure.
It will also cause a waste of manhours, parts, or oil or grease, and at the same time, will also lose the confidence of the user or operator.
For this reason, when carrying out troubleshooting, it is necessary to carry out thorough prior investigation and to carry out troubleshooting in accordance with the fixed procedure.

2. Points to ask the user or operator
1) Have any other problems occurred apart from the problem that has been reported?
2) Was there anything strange about the machine before the failure occurred?
3) Did the failure occur suddenly, or were there problems with the machine condition before this?
4) Under what conditions did the failure occur?
5) Had any repairs been carried out before the failure? When were these repairs carried out?
6) Has the same kind of failure occurred before?

3. Check before troubleshooting
1) Are abnormal symptoms detected in the machine?
2) Make checks before starting day’s work.
3) Make checks of other items.
4) Check other maintenance matters which can be checked externally and are considered to be necessary.

4. Confirming failure
See the extent of the failure by yourself, and judge whether it is a real failure or a problem caused by the handling or operating the machine.
a When operating the machine to reenact the troubleshooting symptoms, do not perform any inspection or measurement that may make the problem worse.
