Safety measures
DANGER!
There is the risk of gas escaping!
System is under pressure:
♦ The operating pressure reaches a value of around
160...200 bar and higher in high-pressure operation, i.e.
in the natural gas pressure containers (CNG), including
connection lines as far as the electromechanical high-
pressure regulator.
♦ The operating pressure achieves a value of around 5...10
bar in low-pressure operation, i.e. at the output of the
electromechanical high-pressure regulator.
Before opening the natural gas system, you first need to empty
it
⇒ “3.18.5 Empty natural gas system (deactivate)”, page 85 .
Even after emptying the natural gas system, residual pressure
is still present in the system.
Before opening the natural gas system lay cleaning cloths
around the connection point. Reduce pressure by carefully re‐
leasing the connection point/bolted connection.
• Wear protective spectacles and protective gloves.
3.18.3 Inspect natural gas system for leak-
tightness
Note
Observe safety measures and other rules
⇒ “3.18.2 Safety measures and rules of cleanliness when working
on vehicles with natural gas system”, page 78 .

formed every 2 years.
The leak tightness test of the natural gas system is also be
carried out:
♦ if components have been loosened or replaced in the high
pressure area of the natural gas system
♦ If components have been loosened or replaced in the low
pressure area of the natural gas system
