Please refer t o Fig. 1 3 for an overview of t he w hole assem bly fully fit t ed.
Place t he caravan on a hard, level surface. The use of a lift ing ram p or an assem bly pit is ideal for access and
personal safet y.
Unpack all the com ponents and check for the presence of all parts ( see package cont ent s list) . Writ e down, on

Clean the area of your chassis where you need to m ount all com ponents to ensure a good fit t ing.
Make sure t he caravan is prepared for inst allat ion. Check before inst allat ion t hat im port ant areas, such as

N ot e
: I n principle, the unit should be fit ted in front of t he caravan road wheels, but if fit ting in this posit ion is
not possible because of obstacles or a too high hitch ball weight , it is perm issible t o fit it t o t he rear of t he
wheels by rot ating the whole assem bly ( Fig. 1) by 180° degrees.
Loosely fit the two clam ping assem blies ( 7) t o the chassis ( Fig. 2 & 13) and attach. Use t he bolts M10x60, nut s
M10 and washers M10 ( 8,17,18) and put them in t he diagonal posit ioned holes of the alum inium chassis clam p
plat es. Nut s m ust be no m ore t han finger- t ight .
Assem ble the pre- m ounted m anoeuvring system on the alum inium chassis clam p plat es by using t he two U-
