
For a braked variant: connect the brake safety rope to the buffer, frame or
towing bracket in rear of the towing vehicle. This rope of the overrun brake system
should be led directly to the towing vehicle and freely for all reciprocal movements
both of the trailer and the vehicle.

If the towing vehicle is equipped with a 13-pin receptacle for transport
lighting, it is possible to use an applicable adapter for a 7-pin plug. The
trailer can be also equipped with a 13-pin plug (option).
While uncoupling the trailer, proceed in reverse order. Do not uncouple the trailer
on a hillside as it is very dangerous. Before uncoupling, make sure if the trailer is
sufficiently blocked against unwilling motion after uncoupling from the vehicle.
Putting aside and parking
Unbraked trailer
Do not uncouple the trailer on a hillside as it is very dangerous. Before uncoupling,
make sure if the trailer is sufficiently blocked against unwilling motion with both
wheels properly chocked and then you can uncouple the towing vehicle. Extrude
the jockey wheel, let it rest on the ground and lock it in its extruded position
mechanically. Should the trailer be uncoupled from a towing vehicle, first unload
the towing bracket by lowering of the jockey wheel as needed.
While putting aside or parking the trailer being coupled to the towing vehicle,
retract the parking brake on the vehicle and, on hilly terrain, block it against
unwilling motion with scotch blocks under both trailer wheels and at least under
one wheel of the towing vehicle.
CAUTION! Before removal of the scotch blocks, first find out if the
parking brake of the towing vehicle can hold the whole set or the trailer
on uneven or rough ground also after this removal.
While putting the trailer aside for a longer brake or storage, for example in winter
time, block the trailer against unwilling motion, underlay it so that its wheels are
supported without load. In this way you can save tires, bearings and springs
considerably.
Trailer loading
While loading on a transport vehicle, the trailer must be properly fixed on the
loading surface, lashed and secured against any displacement or overturning.
This trailer is not designed for handling by crane, i.e. it has no lashing points.
