5.2.1
Automatic load-dependent braking force regulator (ALB)
Only for machines with sprung suspension
WARNING
Risk of crushing, cutting, being caught or drawn in, or impact
through incorrectly functioning brake system.
You must not change the adjustment measurement on the automatic
load-dependent braking force regulator. The adjustment measure-
ment must match the value given on the Haldex ALB plate.
5.2.2
Coupling the brake system
WARNING
Risk of crushing, cutting, being caught or drawn in, or impact
through incorrectly functioning brake system.
When coupling the brake and supply line, ensure that
The sealing rings on the hose couplings are clean
The sealing rings on the hose couplings seal properly
Replace damaged sealing rings immediately
Drain the air reservoir each day before the first use
Only start up with the machine coupled if the pressure gauge on
the tractor shows 5.0 bar
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 couple the hose coupling on the brake line (yellow) first
and then the hose coupling on the supply line (red).
The service brake on the machine is immediately released from
the brake setting if the red hose coupling is coupled.
1. Open the cover on the hose coupling on the tractor.
2. Pneumatic braking system:
Dual-circuit
pneumatic braking system:
2.1 Fasten the brake line hose coupling (yellow) in the yellow
coupling on the tractor, as specified.
2.2 Fasten the supply line hose coupling (red) in the red cou-
pling on the tractor, as specified.
When coupling the supply line (red), the supply pressure
coming from the tractor automatically presses out the ac-
tuator button for the release valve on the trailer brake valve
Single
circuit
pneumatic braking system:
2.1 Fasten the hose coupling (black) to the tractor, as speci-
fied.
3. Release the parking brake and/or remove the wheel chocks.
