1

Keep engine off

Inspection can only be carried out in vehicles with compressed gas tank completely full.

Position exhaust gas hose on the exhaust pipe.

2

Check all components as to tightness: filler box (1), high pressure filter (3), pressure regulation valve (4), purge valve (5), pressure/temperature sensor (6), gas pressure piping, gas pressure hose, fastening screws, crossed screw connections, screwed connections in T

The gas piping components and connections must be moistened with a foaming product, for example, alkaline soap solution or spray to detect leaks. These components and connections should be checked for bubble formation.

In case of leaks

The component or piping involved must be sealed or replaced.
