Hydraulic connections
Connect all hydraulic lines on the towing vehicle. For labelling to identify connection points,
see the stickers on the vehicle and on the couplings.
Check all hydraulic lines for damage and leaks on a daily basis.
Replace all hydraulic hoses completely every 6 years.
Releasing the parking brake
Overrun brake version:
Press in the button at the tip of the actuating lever. Move the lever towards the side panel
while keeping the button depressed. If the actuating lever features an extension, the button
is triggered by the extension and the brake is released.
Parking brake version:
To release the parking brake on the trailer, apply the handbrake lever a little (drawbar eye
direction). It will trigger itself. Then reset the lever arm.
-
Remove the wheel chocks and stow them.
-
Start the towing vehicle engine.
-
Check the service brake and parking brake before starting work.
The parking brake is applied by pulling in the direction of the drawbar eye.
The PB is released by letting down the handbrake lever.
Road traffic regulations must also be observed when using the brakes
(including the parking brake).
