WARNING!
The tow hooks are designed for horizontal
pulling only; not for lifting. Never attempt to lift the bus by
the tow hooks
Front Tow Hooks
Air Tank Schrader Valve
The supply (wet tank), primary (rear brake reservoir), and secondary (front
brake reservoir) air tanks are mounted under the bus, outboard of the chassis
frame rails between the axles.
The supply tank is fitted with a Schrader valve to allow manual pressurization of
the system for service or testing purposes by using a common air hose, without
having to charge the system by running the compressor.
If a service truck rendering assistant is equipped with compressed air, the
Schrader valve can be used to pressurize the air brake system, so that its spring
brakes can be released in order to move the bus.
