ATTENTION!
Destruction of the pump due dry running. The pump is lubricated by the cooling

INFORMATION
The drilling-milling machine is lacquered with a one-component paint. Take this criterion into
account when selecting your cooling lubricant.
The company Optimum Maschinen Germany GmbH does not assume any guarantee for sub-
sequent 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.
