Uncoupling the brake system
WARNING
Risk of crushing, cutting, being caught or drawn in, or impact
through the accidentally rolling machine, if the service brake is
released.
Dual-circuit pneumatic braking system:
Always uncouple the supply line hose coupling (red) first, and
then the brake line hose coupling (yellow).
The service brake of the machine only moves into the brake
position when the red hose coupling has been uncoupled.
Always keep to this order, otherwise the service brake system
will be released and may set the unbraked machine in motion.
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. To do this,
use the parking brake and/or wheel chocks.
2. Pneumatic braking system
Dual-circuit
pneumatic braking system:
2.1 Release the supply line hose coupling (red).
2.2 Release the brake line hose coupling (yellow).
Single
circuit
pneumatic braking system:
2.1 Release the hose coupling (black).
3. Close the hose coupling covers on the tractor.
