Optimum Maschinen Germany GmbH does not accept any liability for subsequent damages
due to unsuitable cooling lubricants.
The flashpoint of the emulsion must be higher than 140°C.
When using non-water-miscible cooling lubricants (oil content > 15%) with a flashpoint, ignitable
aerosol air mixtures might develop. There is a potential danger of explosion.
