Dual-circuit service brake system
The machine does not have a parking brake
.
Always secure the machine with the wheel chocks before you
uncouple the machine from the tractor.
The machine is equipped with a dual-circuit pneumatic braking
system with hydraulically actuated braking cylinder for the brake
shoes in the brake drums.
Compliance with the maintenance intervals is essential for the correct
function of the dual-circuit service brake system.
WARNING
If the machine, when uncoupled from the tractor, has full
compressed air tanks, the compressed air from the air tanks
acts on the brakes and the wheels jam.
The compressed air in the compressed air tank and hence the
braking force will drop continuously until there is a complete
brake failure, if the compressed air tank is not refilled. This is
why the machine may only be parked using wheel chocks.
The brakes are released immediately with a full compressed air
tank when the supply line (red) is connected to the tractor. For
this reason, the machine must be connected to the lower links of
the tractor and the tractor's hand brake must be applied before
the supply line (red) is connected.
The wheel chocks may not be removed until the machine is
connected to the lower links of the tractor and the hand brake is
applied.
To activate the dual-circuit compressed-air brake
system, the tractor requires a compressed-air
brake system which is also dual circuit.
