TRAILER

1

Connecting ball coupling

• Manoeuvre the ball coupling over the trailer device.
• Open and hold the ball coupling.
• Turn the jockey wheel handle clockwise until the ball coupling locks in place.
• Continue to turn the jockey wheel handle until the wheel is fully retracted.
• The support shoe must be firmly engaged in the recess in the outer tube.
• Open the clamp.
• Pull the jockey wheel upwards as far as possible.
• Tighten the clamp.
• Connect the power cable to the towing vehicle.
• Route the breakaway cable through the breakaway cable guide ring and
loop it around the ball plate (see photos - see also the applicable country
regulations for potential possibilities through coupling!).
Caution at option 2: Do not use with removable coupling! If the coupling is not
correctly locked in position, there is a risk of losing the coupling and the trailer.
Caution at option 4: only permissible with DIN 5299 snap hooks - min. 70 (fire
brigade snap hooks).
• Release the hand-brake lever.
• Remove wheel blocks.
Note:
The ball coupling consists of safety indicator 1 (these checks
if the coupling is secured, the green cylinder is visible when installed
correctly) and wear-indicator 2 (these controls the wear limit of the
ball coupling, at red colour area replace immediately, the ball joint
can hang out. The green colour is within acceptable range).
