3.11.1 Fill in hydraulic oil
The hydraulic oil is filled in via the filler cap (1) on the oil
tank.
Fill in oil until the mark (2) on the tank is reached.
Capacity GT25 = 60 litres
Capacity GT30 ; GT40 = 100 litres
Usable hydraulic oil
ISO VG32
The system pressure of the hydraulic pump is already set
at the factory. The hydraulic system is self-venting. Pass-
ing the hydraulic circuit several times by pendulum move-
ment of the table accelerates the self-ventilation.

Coolant circuit
ATTENTION!
The surface grinding machine was painted with a one-component lacquer. Take this criterion
into account when selecting your cooling lubricant.
Optimum Maschinen Germany GmbH does not accept any guarantee for consequential dam-
age caused by unsuitable process abrasives. 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 danger of explosion.
Fill the container (2) of the coolant circuit with your process abrasive.
The total filling quantity in the circuit must not exceed the height of the sedimentation tank
for the grinding sludge (4).
