Before releasing the handbrake, make sure the
bus can not start rolling.
Block the bus wheels or connect the drawbar to
the tow truck.
If anything happens
Use the drawbar when towing!
When the handbrake is released with compressed
air from a tyre in this way, the bus can be braked
with the handbrake but
not
with the foot brake.
Releasing the handbrake with compressed air from
the bus tyre
1. Always start by blocking the wheels, or by connecting the
drawbar to the tow truck so that the bus can not start rolling
when the brake is disengaged.
2. Connect the clamp head of the enclosed tyre inflation hose to
the tyre valve.
3. Lower the handbrake to the drive position.
4. Press the other end of the hose against the pump nipple locat-
ed by the pedals. Press in the blocking valve. The lines to the
parking section of the brake cylinders are now filled from the
tyre. The handbrake will be released provided the pressure in
the tyre exceeds 5 kp/cm
2
(500 kPa), fully released at 5.8–6.6
kp/cm
2
(580–660 kPa).
The bus’s air-pressure gauge will not give a reading. Filling
can be interrupted as soon as the transfer flow has ceased.
5. The bus can now be towed. Note that towing in this case must
be done with a drawbar or similar since the bus is without
brakes.
