♦ Check the bolted connections of the natural gas system at the
given inspection positions -arrows- for tightness.
♦ Guide the measuring tip evenly around the entire bolted con‐
nection for 10 s.
♦ Check all of the bolted connections of the natural gas system!
♦ The measuring tip must be a max. of 5 mm away from the
areas/screw fittings to be checked. Measurement is no longer
possible at larger distances.
WARNING
♦ The gas leak search device - VAS 6227- can be used to
determine whether there is gas in the ambient air.
♦ Because natural gas is lighter than air, it will always rise
to the top.
♦ As an outcome of using the gas leakage detector - VAS
6227- , only the green LED diode for OK should light up.
This is the only permissible test result!
♦ Once a yellow or red LED diode lights up on the gas leak‐
age detector - VAS 6227- , a leak search spray must be
used. A gas leakage can thereby be detected easily at the
tested point!
♦ No bubbles must escape from the sprayed area within a
test period of 3 minutes, when using the leak search spray.
♦ If leakage occurs, it must be rectified through a repair
measure and then the leak tightness test must be repea‐
ted.
If a different gas leakage detector for natural gas vehicles is
used, the limit value of 50 ppm is valid and must not be ex‐
ceeded.
