Uncoupling the brake and supply lines
WARNING
Risk of contusions, cuts, dragging, catching or knocks from
unintentionally rolling machine with the operating brake re-
leased!
Always uncouple the hose coupling of the supply line (red) first fol-
lowed by the hose coupling of the brake line (yellow).
The operating brake of the machine only moves into the brake posi-
tion when the red hose coupling has been uncoupled.
Always keep to this order, as otherwise the operating brake system
will trip and may set the unbraked machine moving.
When the machine is uncoupled or pulled away from the trailer, air is
vented from the trailer brake valve supply line. The trailer brake valve
is automatically switched and operates the service braking system
independently of the automatic, load-dependent braking force regula-
tor.
1. Secure the machine against unintentionally rolling away.
Use chocks.
2. Release supply line coupling head (red).
3. Release brake line coupling head (yellow).
4. Fasten coupling heads in the empty coupling points.
5. Close tractor coupling head caps.
