Hydraulic brake

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!
Fasten the cable in such a way, that it cannot
¾
be caught in any place.
3. Release the parking brake. The ropes must
be relieved, and the wheels must be free
