Please stop the water circulating system at least 30 minutes after completion of cutting process so that the filtration
residue and dust produced during the process will not clog on the surface of filter paper but fall onto the bottom. Hence,
the pressure of filter paper will be reduced when next cutting process begins.

The metal oxide will block the surface of filter paper when cutting nonferrous metals and such hard alloys as aluminum,
tungsten steel and so on. And it shortens the life extension of filters.

Please change working water once or twice within one year to prevent the mud of water and bacteria blocking filters, and
clean the water tank at the same time.

It will shorten the life extension of filters by using antirust.
