2 General information
With the JOST automatic coupling system, known for short as
“KKS”, you have a complete, state-of-the-art vehicle coupling sys-
tem with safety and convenience standards that satisfy ECE-R55,
R13 and ISO 13044-2 requirements.
Improper handling of the automatic coupling system during
installation, repair or operation can result in dangerous sit-
uations. Please pay attention to warnings and safety notices
in section 3 "Safety instructions" and the instructions in
section 4 "Intended use". Please also heed all warnings and safety
notices in this installation and operating manual. You will find an
explanation of hazard symbols in section 1 "Explanation of sym-
bols".
Modifications of any kind may have an impact on safety and are not
permitted. Furthermore, modifications will rule out all warranty
claims and invalidate the vehicle operating licence. Do not use the
product until you are certain that the tractor unit and semi-trailer
on which the JOST KKS is fitted comply with road traffic regulations
in your country.
