Hydraulic brake (optional)
The hydraulic line controls the brake power to
the brake cylinders.
The brake inlet pressure must not exceed
130 bar.
Connection
1. When hitching up connect the hydraulic
brake line with the brake line on the tractor.
2. Fasten the break-away protection cable at
a suitable place on the tractor.
WARNING
The cable may be caught by other machine parts
and thus trigger flat-out braking when cornering.
Danger of traffic accidents!
¾
Fasten the cable in such a way, that it cannot
be caught in any place.
3. Release the parking brake. The ropes must
be relieved and the wheels must be free
to rotate.

Fully kick down the brake pedal on the tractor
for this purpose.
With each actuation of the brake, the pressure
accumulator is pressurized, if required.

2. Apply the parking brake.
3. Place wheel chocks under the wheels.
