Warnings and advisories
Fuel
The engine is designed and optimised to be run
on either natural gas or pure biogas.
WARNING!
Natural gas and pure biogas mainly consist of
methane, and may have a methane content of up
to 97%. Methane is flammable and must be han-
dled with great care.
WARNING!
Methane is not toxic, but in a mixture of 50 per
cent or more with air, the oxygen content will be
so low that the risk of suffocation increases.
IMPORTANT!
Comply with applicable local laws and regula-
tions when handling natural gas and pure biogas.
Methane is a highly flammable gas which is
flammable when present in a 5-16% mixture in
the air.
Methane can even be ignited by static electricity
from a person.
Methane ignites when in contact with hot surfac-
es at approx. 580°C.
Methane burns with an almost invisible flame.
Therefore, take extra care.
Methane is lighter than air and therefore rises in
the event of leakage. Bear this in mind if leaks do
occur in enclosed spaces such as indoors or in a
tunnel. In those cases the gas can cause suffoca-
tion and an explosive atmosphere.
Smoking
WARNING!
Smoking is prohibited in the vicinity of gas en-
gines.
