INFORMATION
The CNC-milling machine is lacquered with a one-component paint. Observe this fact when
selecting your cooling lubricant.
The company Optimum Maschinen Germany GmbH does not assume any guarantee on subse-
quent damages due to unsuitable cooling lubricants.
The flashing point of the emulsion must be higher than 140°C.
When using non water-mixable cooling lubricants (oil content > 15%) with flashing point ignita-
ble aerosol air mixtures might develop. There is a potential danger of explosion.
3.8 Refill central lubrication system
The CNC-machine is equipped with a central lubrication system.
INFORMATION
The CNC-milling machine is delivered without lubricating oil. The central lubrication system is
depending on the model in the working area on the column of the spindle or at other locations.

Fill the tank with lubricating oil via the filler hole.

3.9 Functional test and controls
Rotation coolant pump

Check the direction of rotation of the CNC-machine.There must be a right-handed rotating
field. If the direction of rotation is wrong, exchange two of the three phase conductors. At
this, the correct direction of rotation only refers to the drive of the cooling lubricant pumps.
INFORMATION
The rotational direction of the coolant pump can not be checked in the built in state. If no cool-
ant flows the rotational direction of the coolant pump may be wrong.
Proceeding to set the direction of rotation:


Close the sliding door and turn on the coolant supply.

Check if cooling agent flows.

WARNING!
Never change the dosing of the cooling lubricant supply when a program is running.

If no coolant is flowing and thus the rotational direction of the coolant pump may be wrong,
- first check the coolant level in the coolant tank,
- and then replace two of three phases (e.g. L1 and L2) in the control cabinet on the circuit
