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.
Use
Intended use
Use the pressure regulator for compressed or liquefied gases discharged under pressure. The pressure
reducer reduces intake pressures of up to 200 bar to the desired pressure value, maintaining it constant.
Thus, the pre-set flow rate is ensured.
Improper use
•Do not use the pressure regulator with gases in liquid state.
•Do not use unstable or corrosive gases.
Safety instructions
•The pressure regulator for gas cylinders must not be changed or modified.
•No adaptors may be used between the gas cylinder valve and pressure regulator.
•If operated or used improperly, the device can cause dangers to the user and other persons
and damages to the device.
•The local prescriptions with regard to the proper use of the device must be obeyed.
•All parts coming into contact with oxygen must stay free of oil and grease. Fire and
explosion hazard!
•Smoking or open flames near any gas supply system is strictly forbidden. Fire and
explosion hazard!
•Always open the valve slowly.
•The pressure regulator must not be exposed to temperatures beneath –30 ℃or above +60 ℃.
•The gas cylinder must be protected from downfalls.
Attention! Obey the warning precautions found on the stickers on the device!

Assembly
1. Before assembling, clean the threads and lines. Make sure that no contaminants may get into
the pressure line.
2. Make sure that the air flows into the direction of the arrow found on the product. Before use, re-
check all connections.
3. Pressure regulation: Pull the knob upwards and turn it clockwise to increase the pressure.
Turn the knob counter-clockwise to reduce the pressure. Once the desired pressure is set, press
the knob to lock it.
4. Drain: The water can be drained automatically when there is no pressure build-up. If pressure
has built up, the water is drained by pressing the water drain knob. After draining the water,
release the knob to stop drain. In case the water level exceeds its maximum, immediately drain
the water by hand, for otherwise the drain line might deteriorate.
5. Oil quantity regulation: The oil drain is reduced by turning the needle valve clockwise. The oil
drain is increased by turning the needle valve anti-clockwise. Once the needle valve is adjusted,
the oil drain adapts to the air flow.
6. Re-filling: Re-filling can be done without interrupting the air flow. Untighten the oil screw coun-
ter-clockwise to re-fill. The level must not exceed 80 %. Re-tighten the oil screw after re-filling.
Do not remove the oil container itself for re-filling.
Maintenance
1. Clean/replace the filter: Remove the filter, let the air escape from the inside to outside. The
filter is now operational again.
2. Transparent plastic cap: Remove the plastic cap to clean it with a dry and clean cloth. Do not
use chemical products that might with plastics.
