Built in 2010, the model carries a payload of around 14,800 kg against an unladen weight of 5,700 kg. At 12,200 mm long, 2,550 mm wide, with four wheels and a 9,380 mm spread between kingpin and rear axle, the build is shorter than the long standard semi-trailer used in long-haul traffic, pointing to a more compact intended use.

Class O4 semi-trailers run on air brakes controlled through the tractor's brake line and require a category CE licence to tow. The shorter build with only two axles rather than a three-axle group points to use in distribution traffic or with more compact loads rather than long palletised or volume freight.

Buying a used semi-trailer of this kind, the kingpin and its wear plate deserve particular attention, since this is the direct contact point with the fifth wheel. In addition, the air brake system should be checked for leaks, both axles for play, and the chassis around the axle mounts for corrosion after more than a decade of service. The landing gear legs and their winding gearbox are worth testing under load too, since a stiff or bent leg makes coupling and uncoupling difficult.
