In theory, this is a modern citybus, and i'm sure King Long has
configured it with air suspensions, and the suspension/raisers
that can be adjusted both by the driver and the bus itself.
Probably when it first arrived, the settings were not
configured properly or the driver's not familiar. Tons of
possiblities.......
Like it or not, the vehicle will be trialled, it's mentioned in the
PDF in my earlier post.
I'll assume the air suspension is at least controllable from the
dashboard... if so the bus would not be needed to be raised
manually by technicians. The setting to input air into the
suspension is always there, it does not need to be configured
except in the case of the MAN A22s, which is 'automatic' like the
VSOs, but at least its high enough to clear most humps and
radiants.
