In released position the brake lever should touch
the fork at the front and the wheels should be
able to turn freely.
¾
To ensure the function of the valves, anti-freeze
should be mixed into the compressed air. Follow
the operating instructions of the tractor!
¾
The coupling heads should be closed with blind
covers or a plastic bag to protect against dam-
age caused by moisture.
¾
Release the brake. Brake pads may otherwise
stick to the drum and make restarting of the
machine more difficult.
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 lines with the brake lines 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.

WARNING
Danger of traffic accidents caused by brake failure!
During commissioning or after long periods of rest:
¾
Fill the pressure accumulator for emergency
braking before starting to drive.
¾
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.
Unhitching
1.
Park the machine.
2.
Apply the parking brake.
3.
Place wheel chocks under the wheels.
4.
Loosen the brake line.
5. Disconnect the break-away cable from the
tractor.
6. Unhitch the machine.
Unhitching does not trigger the breakaway brake.
Emergency braking is only triggered if the spring
cotter is turned to the front.
