8. Installation:

Coupling heads are safety-critical components!
Therefore, the following points must be observed during installation:
Before the start of installation, the parking brake must be engaged on the trailer
and the wheels must be secured with wheel chocks.
To prevent the trailer from tipping up during installation, it should also be secured
by the outriggers / with supports at the front and rear on the frame.
Before the start of installation, check whether the installation space provi
ded on the overrun device is free from any third-party parts (such as the
handbrake lever or other attachments). No part of the stabiliser coupling
head should make contact with any other part, even if the drawbar is fully
pushed in!See also point 9 in this regard
If the wall thickness of the drawbar tube is less than 5 mm, spacer sleeves are man-
datory.
The stabilising coupling head is attached to the drawbar with the following bolts
and self-locking nuts:
Model
Screw connection
Tightening torque
When selecting the bolt sizes, always select the largest possible bolts accor
ding to the through holes in the drawbar of the overrun device.
When doing so, always ensure that the drawbar onto which the coupling head is
being installed is not deformed.
Spacer sleeves may be required.
The nuts used must be strength class 10 and be self-locking. These may only be used
once.
The design of the bolted connection must allow for the possibility of retightening
all the bolts.
The connection dimension of the drawbar must not deviate by more than ±0.5 mm
from the nominal connection diameter of the coupling head. Otherwise, a different
version of the coupling head must be selected or the corresponding adaptor plate
must be used.
