Instruments and controls
Blocking valve, handbrake
If for some reason the air brake system is empty, due to the
bus being parked a long period of time for example, the
handbrake can not be released until the blocking valve has
been pushed in.
Even if the hand control for the handbrake is in its forward
position, the brake will not release until the blocking valve is
pushed in. It can be released only when the air brake sys-
tem warning light has gone out.
Low air-pressure, handbrake
The warning light comes on when the handbrake is applied
or if the air pressure in the handbrake circuit is too low to
allow the handbrake to be released.
The warning light will stay on until the pressure has
reached approximately 540 kPa (5.4 kp/cm
2
).
Never begin driving as long as the warning light is on.
Stop immediately if it comes on while driving:
There is a risk that the handbrake can
be applied unintentionally.
If a fault occurs in the footbrake system while driving, the
handbrake can be used as an emergency brake.
