Important notes on the steering
system
The dimensions of the steering system
and the mechanical steering transmis-
sion ratio were designed such that,
in the event of a malfunction in the
hydraulic power steering system, the
effort required to turn the steering
wheel would not exceed a specific
value deemed by legislators to be the
maximum reasonable force.
For vehicles above 12 t this force is 450
N (400 N for vehicles between 3.5 t and
12 t) applied to the steering wheel cir-
cumference when turning the vehicle
from straight-ahead driving into a circle
with a 20 m radius at a road speed of
approximately 10 km/h. No more than
6 seconds must pass from the start of
turning to reaching the 20 m radius.
The driver must be aware that, in the
event of a sudden failure in the power
steering (e.g. due to a pump drive mal-
function), the bus will remain steerable

but considerably more effort will be re-
quired.
Since there is an extremely low probab-
ility of this situation occurring - but if it
does occur, it often does so completely
unexpectedly - the driver could wrongly
assume that the steering system has
been blocked. In fact, the driver merely
has to use the level of effort required to
continue steering.
This important information is intended to
clarify the scenario described and pre-
vent the driver from possibly misjudging
the situation.
Danger.
In the event of a power steering failure,
the bus becomes very difficult to steer.
Have the malfunction rectified immedi-
ately at an EvoBus Service Partner.
