[ Problem Point ]
Food wasted oil sometimes overflowed from the drum.
[ ⇒Kaizen Point ]
We are near the residential area, so DLC-100L of the warning light type, not the bell type was installed.
If oil became near fill up the drum, the light shone,
so the time to call waste oil recyclers became clear.
