work, and then comply with them.
Please ensure that no metal chips or other contaminants get
into the control unit during installation.
The accessories described in the installation instructions can
be obtained from your dealer.
Intended use
The Manoeuvring Assistant was designed for use on single-
axle caravans with a gross weight of up to 1800 kg.
The Manoeuvring Assistant weighs approx. 34 kg with the
cross actuation device fitted.
Check the maximum towable weight for your towing vehicle
and the gross weight of your caravan to make sure that they
are designed for this additional weight.
Approval
The RH 1 Manoeuvring Assistant has design approval, and a
general operating permit (ABE) has been issued for Germany.
Acceptance by a vehicle expert is not required (except when
installing the low chassis kit). The general operating permit (ABE)
must be kept in the vehicle.
The Manoeuvring Assistant complies with other require-
ments of EU Directives and Standards (see Declaration of
Conformity).
When installing the Manoeuvring Assistant, the technical and
administrative regulations of the country of first registration of
the vehicle must be observed.
Any modifications made to the device, or the use of any spare
parts or functionally significant accessories other than original
parts, or failure to comply with the contents of the operating
and installation instructions invalidates the warranty and pre-
cludes any liability claims. This will also invalidate the operating
permit for the equipment.

Determining the installation type
1. Standard installation
Standard installation is used with a U or L-profile chassis and a
frame height of approx. 170 mm. No special accessories are
required.
2. Installation on chassis with U or L-profile with a frame
height of between 110 and less than 170 mm
In the case of a chassis with a frame height of 110 mm to
170 mm, 1, 2 or 3 spacer plate sets and the set of bolts are
required.
3. Installation on chassis with U or L profiles with a frame
height of less than 110 mm
If the chassis has a frame height of less than 110 mm, a low
chassis kit must be fitted to compensate for the height.
If a low chassis kit is used in Germany, acceptance by a
vehicle expert is required.
4. The AL-KO Dario III / AV installation kit must be used with
the AL-KO Vario III / AV chassis with a frame thickness of less
than 2.8 mm.
