Avoid using external undue force on the gas pressure regulator,
since this may lead to malfunctions�
Do not impede the reset button’s movement using objects�
2.1.2 Component installation and connection
Component connections may be leaky if they are incorrectly installed,
damaged or dirty�
Use high-pressure hoses under all circumstances for high-pres-
sure connections between the gas cylinder and the gas pressure
regulator or gas filter�
When connecting the high-pressure hoses, ensure that the seals
at the respective hose outlets are present and undamaged�
Securely fasten all parts to stable structures to prevent damage
due to vehicle vibrations while driving�
Replace gas hoses immediately if they have been completely or
partially damaged or were changed in any way�
Keep connections free from dirt�
2.1.3 Handling liquid gas
The use of upright gas cylinders from which gas is extracted in the
gas phase is mandatory when operating the gas pressure regulator�
If a gas cylinder is on its side, liquid can penetrate low-pressure
parts, damage sensitive parts and lead to dangerous gas leaks� Gas
cylinders from which gas is taken in the liquid phase (e�g� for fork
lifts) must not be used, since they would result in damage to the gas
system�
Only use gas cylinders in an upright position�
Do not use gas cylinders that provide gas from the liquid phase�
Gas cylinders that are not connected to the gas system must be
closed at all times and provided with protection caps�
Connected gas cylinders are considered to be operating materials
and not hazardous materials (ADR exemption in accordance with
sections 1�1�3�1 and 1�1�3�2 e)�
