Raising the vehicle:

When raising the vehicle, make sure that the rota-
ry disc valve is moved back to the "stop" position
once the required height has been reached. Locking
the valve in "raise" position can cause damage to
the air bags. To prevent damage of this kind, the
extension of the vehicle can be restricted using a
stroke limiter (see page 55).
Particular operating conditions:

Under certain operating conditions, all extensions
must be limited using a stroke limiter (see page 55.)
