Introduction
Thank you for choosing to purchase this quality product. To minimise the risk of injury, we ask you to
always take some basic safety precautions when using this product. Please read this operating manual
carefully and make sure that you understand it.
Keep these operation instructions in a safe place.
Safety instructions
Caution!
•The use of this device is only allowed with a fault current protection switch with a triggering
nominal current up to 30 mA (according to VDE 0100 Article 702 and 738).
•The device is not intended for use by persons (including children) with impaired or limited
physical, sensory and mental abilities or lack of experience and/or real knowledge, unless they
are supervised by a person responsible for their safety or follow the instructions made by this
person on how to correctly use the device.
•Children should be supervised to ensure that they do not play with the device.
Attention!
•The compressor head can become very hot. Burning hazard!
•Perform a visual inspection of the device before every use. Do not use the device if the safety
appliances are damaged or worn out. Never override safety regulations.
•Only use the device accordingly to the intended purpose stated in this manual.
•You are responsible for the safety of the working zone.
•If the cable or the plug is damaged due to external influences, the cable must not be repaired,
but has to be replaced with a new one. This work can only be carried out by an electrician.
•The voltage of 230 V AC indicated on the nameplate of the device must match the existent
mains voltage.
•Never lift, transport, or suspend the device by its power cord.
•Make sure that the electrical plug connection is protected from flood and moisture.
•Before any maintenance work or adjustment, pull out the plug.
•The user is responsible for complying with local safety and mounting regulations. Ask an
electrician if you have questions.
•In case of device failure, repairs can only be carried out by an electrician.
Notes!
•Choose the right compressor with the appropriate air volume and air pressure to match the
actual work requirements.
•Never expose the device to dust, acid, steam, explosive or flammable gases, or weather
influences (rain, sun, fog, snow).
•The vacuum pump can only be operated in an appropriate environment (good ventilation,
ambient temperature +5 ℃–+40 ℃.
•Never use the compressor barefoot or with wet hands or feet.
•Never allow children to touch the switched-on compressor or to insert the plug. It may cause
burns or electric shocks.
•Do not open or damage any part of the compressor. If necessary, contact a qualified person.
•By opening the drain valve, the water can be evacuated. Always release the water before not
using the compressor for a long time. Store the compressor in a well-ventilated place.
•Always wear protective goggles. Under no circumstances should you direct the airflow towards
your body or other persons’ bodies or animals.

•Never use the compressor in areas with vapours or humidity or near bodies of water.
•Switch off the compressor if you do not use it. Disconnect from mains before you repair,
recondition, maintain, clean, or replace parts. Never use the power cable as handle. Keep the
cable away from heat, oil, or sharp edges. Protect it from breaking. Do not pull out the plug by
pulling the power cable.
•If the compressor is used outdoors, only approved extensions may be used. Every wire of the
extension cable must have at least a 1,5 mm² cross-section.
•Store the compressor in a well-ventilated place. Do not allow children or any other people not
able to handle this device to play or work with it.
•Be very careful when working with the compressor. Do not perform work with this product when
being unalert or influenced by alcohol, drugs, or medicine.
•When beginning work, make sure that all screws are tightened.
•Do not use the compressor if it is damaged. If the compressor makes unusual noises and strong
vibrations or if other unusual signs occur that indicate some damage, immediately turn off the
compressor. Do not modify the compressor in any way. Only have repairs made by qualified
persons and using original spare parts.

User notes
•The compressor has a 9.51 mm (⅛″) outlet with external thread which can be effortlessly
changed to ¼″. The matching adapter is not included in the delivery.
•When the compressor is connected by the hose to the airbrush gun, it can be connected to the
mains and switched on.
•The maximum pressure is displayed the pressure gauge, the operating pressure can be
adjusted by the pressure regulator.
•The hose included in the delivery is air-tight. If the auto-stop mode is activated (repeatedly
switched on/off) any and all screw fittings and connections should be sealed by sealing tape.
Leakage check
•Switch on the compressor and wait until the maximum pressure has built up and the auto-stop
function has been activated.
•If there is no leakage, the pressure gauge should display nearly constantly the same range of
pressure.
•A quick decrease of the range of pressure suggests that there is in fact a leakage.
•It is of great importance to seal any leak as soon as possible in order to avoid any impact on
the capacity and efficiency of the compressor.
•A leakage leads to the auto-stop and auto-start constantly being switched on and off.
Difference between maximum pressure and operating pressure
•The maximum pressure is the highest possible pressure that a compressor is able to generate.
•The maximum pressure is the pressure measured only inside the compressor itself.
•Once the maximum pressure has been reached, the compressor switches off (auto-stop), and
as soon as the pressure starts to decrease, it switches on again (auto-start).
•On the outlet of the compressor, there is a lower pressure. What remains is the pressure that
you actually work with. The operating pressure may vary according to the connected airbrush
gun.

Operating the pressure regulator with filter
a) Pressure regulator
b) Pressure gauge
c) Water drain plug
Product name: Pressure regulator with filter and manometer
Type: AFR-2000
Properties
AFR-2000 is an in-line low-pressure regulator with 9 bar (130 psi) manometer and water drain plug. This
regulator allows you to control the pressure and helps generating clean, dry, and stable air pressure.
The regulator can only be used according to the operating instructions.
Operation:
1. The pressure gauge reports the working pressure of the air tool.
2. Pull up the adjusting knob; a clockwise rotation increases the pressure, a counter-clockwise
rotation reduces the pressure.
3. Rotate the adjusting knob to achieve the right working pressure and engage it by pushing it
downwards.
4. Do not rotate the knob against high resistance. If necessary, the height and position of the knob
can vary slightly.
5. For emptying the condensed water collector, use the water drain plug.
