mounted behind the wheels by turning the entire assembly 180° (Note: In this case, observe the
wiring diagram of the rear axle when wiring your system). Make sure that the main cross mem-
ber (3) is positioned in the centre of the caravan/parking aid assembly (the centre is marked).
Adjust the lateral position of each side of the motor so that the rollers are in the centre of the
tyre or as close to the centre as possible and ensure that there is a 10 mm gap between the tyre
and the manoeuvring aid gear (Fig.10).
On one side of the vehicle, lift the frame assembly and loosely attach the clamp assembly to the
frame and chassis as shown in Fig.14. The supplied clamp fixings (7, 16, 17, 18) must only be
hand tightened at this stage. Once the loose fixings are self-supporting, repeat the process on
the other side of the vehicle.
Use due caution when lifting and fixing the frame and brackets. Use lifting aids and/or a second
person when lifting/assembling.
If the main assembly is loosely mounted on the chassis, slide the entire assembly along the chas-
sis until the rollers are 20 mm from the surface of each tyre (Fig.8). Two 20 mm spacers (30) are
provided to adjust this distance. Note that the drive units should be in the disengaged position
when the 20 mm distance is set. When adjusting the spacing, ensure that the rollers of both
drive units are centred on the vehicle tyres both horizontally and vertically to ensure the best
possible wheel contact (see Fig. 10 for reference). If the roller widths exceed those of the tyre,
ensure that the end of the roller forms a common alignment with the outer wall of the tyre. An
overhang on the inner wall of the tyre is acceptable for thinner tyres and should not drastically
affect function or grip.
It is important that each roller has exactly the same distance to the tyre. The entire assembly
must be parallel to the axle of the caravan/trailer for the system to function as intended.
When you are satisfied with the distance between the castors, tighten the four Nyloc nuts (17)
on both clamp assemblies (Fig. 14) to a torque of 55Nm, then tighten the bolts (Fig. 1.B and
Fig. 1.C) on each engine side frame to a torque of 12Nm. Check again the distance of 20mm
between the rollers and the tyres and if necessary loosen the screws and readjust the position
of the assembly. When you are satisfied with the position of the assembly, fit the chassis stop
nuts and bolts (7) in each of the upper classic clamp plates (8) and tighten them (see Fig.14).
Tighten them to a torque of 55Nm. The stop bolts grip the lip of the chassis and prevent the
manoeuvring aid from slipping on the chassis. The most important mechanical components are
now installed.
