The installation steps up to operation are:
Machine installation diagram
- Power connection
- Ethernet network cable
- Pneumatic hose
- External compressed air supply
Establishing the electric connection
The machine requires an uninterruptible power supply for proper operation.
- Plug the provided power cable into the mains connection on the connection panel of the machine.
-
NOTICE! To avoid job interruptions, install an uninterruptible power supply (UPS), type online / VFI (IEC 62040-3, Class 1) if there are regular power failures or frequent mains voltage fluctuations.
- Insert the plug of the cable into a socket that is protected by a Residual Current Device / Ground Fault Circuit Interrupter.
Installing the pneumatics
Risk of injuries through leaking compressed air and lashing pneumatic hoses
Open or loose pneumatic connections can cause severe injuries.
- Ensure that during installation and maintenance of the pneumatic hoses and of the compressed air regulator compressed air is not conducted through the hoses and connections.
- Before conducting compressed air through the hoses and connectors, verify that the hoses are securely inserted into the correct connectors and that they are not damaged. This also applies to the compressed air regulator.
- Do not conduct compressed air through damaged hoses and connectors.
Bearing failure and electrical damage to the spindle in case of contaminated compressed air
The incoming compressed air must be dry and oil-free according to ISO 8573-1:2010 because the compressed air regulator only serves as an indicator for contaminated air.

- Ensure that the compressed air meets the above requirements.
- Only connect the machine to the compressed air supply if the compressed air regulator is properly installed.
You can find specific values and additional requirements in the chapter on technical data. Technical data
The machine requires the compressed air for the following tasks:
- For the opening and closing of the collet chuck during tool changes.
- For the spindle sealing air which prevents foreign bodies from entering the spindle.
- For the sealing air in the working chamber that keeps machining debris away from sensitive machine parts.
Overview compressed air regulator
The machine is connected to the external air supply via a compressed air regulator. You can use this regulator to monitor and regulate the pressure of the incoming air.
- 1/8” internal thread, fitted with male compressed air connector to connect the external compressed air supply
- 6 mm push-in fitting to connect the machine.
Failure of the water separator caused by a wrong alignment of the compressed air regulator
The compressed air regulator must always be mounted in an upright position because otherwise the water separator will not work.
On the left side of the machine are 2 drill holes that you can use to mount the compressed air regulator on the machine.
- Mount the compressed air regulator in an upright position, using the oval-head screws provided in the drill holes.
Installing the pneumatic hose
- Close the main external compressed air supply valve.
- Use the provided pneumatic hose to connect the right pneumatic connection of the compressed air regulator to the pneumatic connection of the machine.
- Connect the external compressed air supply to the left pneumatic connection of the compressed air regulator.
- Thoroughly verify that all external pneumatic hoses are properly seated in their corresponding connections and that the hoses and connectors are undamaged.
- If all hoses and connectors are properly installed and undamaged, open the external compressed air supply valve.
Adjusting the air pressure with the compressed air regulator
Setting the air pressure is only necessary if the air pressure shown by the pressure gauge does not lie between the minimum and maximum air pressure. You can find specific values and additional requirements in the chapter on technical data.
- Rotary knob for pressure regulation
- Pressure gauge for monitoring the outgoing air pressure
- Bowl of the water separator
- Discharge screw
-
Pull the rotary knob on top of the compressed air regulator slightly upwards.
- Turn the rotary knob in the desired direction:
- Turn it in the “+” direction to increase the pressure
- Turn it in the “-” direction to decrease the pressure
- Push the rotary knob down again.
- The knob is locked and cannot be changed inadvertently.
