Risk of accidents if the trailer is coupled improperly!
If the pin is protruding from the guide bushing, the trailer is not coupled properly
and could become disengaged from the towbar coupling while driving.
G
Risk of accidents if the hoses are too short or incorrectly routed!
The hose lines may not come off even when driving around corners. When
connecting the hoses, make sure they are long enough and have enough
clearance.
