Coupling and uncoupling the machine
WARNING
If the Cirrus is parked uncoupled from the tractor with a full
compressed air tank, the compressed air of the compressed air
tank acts on the brakes and the wheels are then blocked.
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. The Cir-
rus must therefore be parked only with wheel chocks.
The brakes are released immediately with a full compressed air
tank when the supply line (red) is connected to the tractor. Be-
fore connection of the supply line (red) the Cirrus must there-
fore be connected to the tractor's lower links and the tractor
parking brake must be applied. The wheel chocks must also not
be removed until the Cirrus is connected to the tractor's lower
links and the tractor parking brake is applied.
Coupling the machine:
1. Check whether the Cirrus is secured with
2 2 x 2 wheel chocks (1Fig. 103) on each
side of the machine under the outer tapered
ring tyres.
Fig. 103
2. Secure a ball (Fig. 104/1) with trap bowl
above the lower link pin (cat. III) of the draw
bar and secure it with a clip pin.
The balls of the lower linkage are depend-
ent on the tractor type (see tractor operating
manual).
Cirrus 3002 and Cirrus 4002-2 can be
equipped with lower link pins (cat. II).
