Wet machining without suitable cooling liquid can
damage the machine, tools and blanks.
Before you execute a job, ensure that the cooling
liquid is clean and the liquid level is sufficient.
Only use cooling liquid that meets the require-
ments listed below.
Exchange used cooling liquid according to the
maintenance table. Clean the cooling liquid tank
before refilling it.

the maintenance table.Of course, you can exchange
the cooling liquid at any time.

container as follows:
