Important safety notes
G
WARNING
If the power supply is interrupted with the
EMERGENCY OFF switch, the engine is
switched off automatically. Safety-relevant
functions may therefore be restricted or
unavailable, e.g. power steering, lighting sys-
tem and ABS. The compressed-air supply
fails. To steer, you will require considerably
more force. The wheels could lock during
braking. Also, the spring-loaded parking
brake can activate if there is a loss of
compressed air and the vehicle may then
brake uncontrollably. You could lose control
of the vehicle. There is a risk of an accident.
Only use the EMERGENCY OFF switch in
hazardous situations, and only when the
vehicle is stationary.
In the event of an emergency, interrupt the
power supply with the EMERGENCY OFF
switch. This prevents short circuits, which
could create sparks that might in turn cause a
fire or an explosion. Depending on the ADR
classification, vehicles for the transport of haz-
ardous goods can be equipped with various
EMERGENCY OFF switches.
