The video discusses the three main rules of troubleshooting any machine. It’s always a good idea to work smarter than to work harder when performing machine shop repair. Therefore, the first rule of troubleshooting is to check for the easiest and quickest issues first. For example, you should make sure a non-working item is plugged in before assuming it needs a new part.
Secondly, you should always go through the appropriate diagnostic and testing processes. Don’t ever rely on someone else’s words, even if that person is a professional who claims to have run certain tests. You should perform the tests a second time yourself.
The third concept to remember when attempting to fix an issue is that 90 percent of all problems have to do with human errors. Sometimes it’s not that the machine doesn’t work but that the individual operating it may have handled something inappropriately. That’s why it’s essential to read the user manual to the machinery several times to ensure you’re fully educated about its operations. The manual can assist you with fixing issues as well.
You can fix anything by studying the manual, observing the item’s operation, and following the rules mentioned in this video.
