Hello, everyone.

This is Enta.

Do you perform machine maintenance?

I've got a little free time this week in between work.

There are only three of us, though.

The other slope teams and the anchor team have packed schedules, so I'm a little nervous about whether we can make any adjustments lol.

I'll take care of some equipment maintenance during that brief break.

Machines perform differently from one job site to the next.

It’s quite common for something that was working fine until the last time to suddenly break and stop working this time.

We inspect the machines one by one to make sure that doesn't happen.

But the inspections we often do on-site—like checking generators and compressors—aren't really helpful, lol (though inspections are just common sense).

That's because large machinery, such as generators, rarely breaks down in the first place, and it's almost always rented.

However, there may be some wear and tear over time.

It's really hard to tell which parts of the sprayers and core drills we use all the time are prone to breaking.

Invisible metal fatigue strikes all at onceThat's right!

That's why there are many parts that can't be seen even during an inspection.

There’s a director who’s furious because the equipment broke down, but there’s nothing we can do about this.

It just breaks out of the blue! Even the repairman was surprised lol.

It would be great if I could take it apart and service it every time I got back from a job site, but that’s just not possible.

It broke on site, so we did a quick temporary fix, and then did a major repair after the job was finished.

However,Actually, there are signsRight?

The ones who know that are the drillers and the borehole operators—the people who actually operate the machinery.

There are some subtle unusual noises—like air leaks, rattling, wobbling, and so on.

Since it's hard to pinpoint the cause at this point, we can't take any emergency measures. (We can't identify the cause.)

There are many things you only realize once something breaks. Of course, if it clearly looks bad, you replace it right away.

The problem is that by the time I get to the next job site, I’ve completely forgotten all about this glitch, lol.

If employees can effectively communicate these issues to one another, we’ll be able to fix them when we get back to the office, so,

The machine will run smoothly at the next job site, too. Detailed communication like this is really important.

And, compared to the pre-construction inspection, the equipment inspection...It is more effective to conduct inspections during construction.

A pre-construction inspection is a piece of cake, right? lol

See you later.
