Tire Inflation Valve

Tire inflation valve may be used to:
•
inflate a tire using the bus pneumatic
system
•
release the parking brake with air from a
tire
Its main use is to release the parking brake
in a situation when the bus cannot supply its
own air, e.g. engine breakdown.
The bus toolbox contains a hose that connects
between the tire and the tire inflation valve.
The tire inflation valve is located next to the
driver's seat or inside the first service hatch.

External Air Supply Connection

Behind the front hatch there is a valve
to which an external air supply can be
connected. This could be used when parking
the bus overnight, to prevent emptying of the
air system.
