INFORMATION
The milling machine has been painted with varnish. This fact must be taken into account when
selecting your cooling lubricant. Optimum Maschinen Germany GmbH does not accept any lia-
bility for subsequent damages due to unsuitable cooling lubricants. The flashpoint of the emul-
sion 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 dan-
ger of explosion.
