1- hydraulic couplers (red)
After connecting brake conduit of trailer coupler, they shall be automatically engaged after pressing
foot brake pedals in tractor. Pressure in brake conduit shall be proportional to the force of pressure on brake
pedal and amount to max. 150 bar.
Main brake pedals must always be locked together with catch, to ensure correct action of trailer
brakes.
In the event of not using hydraulic coupler to brake trailer, it should be covered with anti-dust cover.
ATTENTION: With engine switched off, hydraulic pressure may not be transferred to
trailer braking system. When parking tractor-trailer assembly engage tractor and trailer
hand brake with working engine.
Therefore brakes should always be locked together with catch, if a trailer braking
system is connected to tractor.
