Operating the bolt coupling
Preparation

Before using the coupling for the first
time, ensure that the towing vehicle /
trailer connection is permitted.
- Do the trailer coupling size and the
size of the towing ring match?
- Can the maximum permissible
drawbar load of the trailer be pulled by
the coupling of the towing vehicle?
- Do the positions of the towing facility
on the trailer and the mounting height
of the bolt coupling match, so that the
towing ring is horizontal when coupled
on a smooth, horizontal surface?
(A maximum deviation of +/- 3
degrees is permitted.)
Information about the
operation of the bolt coupling
may be found in the
manufacturer's operating
instructions.
