Toilet key does not work Inspection repair or replacement

"Sometimes the toilet key isn't locked, so please take a look."

It was a detached house of old sisters.Perhaps the power was weak, the toilet was not locked and it was the content of the ride.

When I inspected it, it seemed that it might get caught a little, but if I didn't care about the operation, there was no problem.

However, considering the age of the client, it will move a little more smoothly.I decided to disassemble and repair it.

A part of the lower cam lock plate rubs and feels friction.By scraping this part and greased it up, it works more smoothly.

We were pleased to check the operation after the completion.After that, I was asked to change the fluorescent light in the back room, but I suggested that I ask the usual electrician, and I refrained from doing this this time.
