5.15.2.1 Emergency brake valve
WARNING
Risk of infection to people due to hydraulic oil squirting out
under high pressure and entering the body!
Always ensure to depressurize the pressure accumulator before
carrying out work on the hydraulic system.
If injuries caused by hydraulic oil occur, immediately contact the
medical services.
The brakes must be tested before each journey to refill the pressure
accumulator.
If the machine is torn off, the ripcord will actuate the emergency brake valve. The hydraulic oil then
flows from the pressure accumulator into the brake cylinders, thus initiating the braking process.
Couple:
1. Fasten the ripcord to the tractor such that in case of the machine being torn off, the ripcord is in a
horizontal position between tractor and machine.
Couple after emergency braking:
1. Connect the brake hose to the tractor.
2. Set the brake valve at the tractor such that the hydraulic oil can flow back to the tractor.
3. Press the drain valve at the emergency brake valve.
The hydraulic oil flows back to the tractor and the pressure accumulator is depressurized.
4. Insert the ripcord with the clip connector into the borehole of the operating lever.
5. Set the operating lever back to its initial position.
6. Actuate the brake system of the machine several times.
The pressure accumulator is filled and the emergency brake valve is ready for operation again.
Uncouple:
1. Make sure that the hydraulic pipe between tractor and machine has been depressurized.
2. Secure tractor and machine against accidental rolling by means of the parking brake.
The emergency brake valve does not replace the parking brake!
3. Remove the ripcord from the tractor.
