9. Operation:

For safe coupling and uncoupling of the trailer, make sure:
-To check the clearance around the coupling ball as well as for possible obstructions
caused by the spare wheel, frame or superstructures. Also check the maximum pos-
sible overrun travel of the overrun device and the possible rotation of the drawbar
on both sides.
There must be clearance even
with fully pushed-in and la-
terally rotated drawbar!
-The trailer must be loaded uniformly without exceeding the permissible axle load
or vertical load (S) (indicated on the rating plates).
-For the purpose of checking the secure attachment of the coupling head, always
check the position of the wear indicator as well as the clearance between the cou-
pling head and the coupling ball.
-If there is play between the coupling ball and coupling head, which is noticeable
during operation, e.g. through any knocking, then this means that the coupling
head/coupling ball are worn out and must be replaced immediately with new ones.
The minimum diameter of the coupling ball, measured at its smallest point, is 49
mm. If the smallest measured diameter is less than this it must be replaced.
In the event of damage or deformation to the coupling head it must be replaced
immediately.
Coupling heads are safety-critical components, therefore no changes to the cou-
pling heads are allowed!
