I N STALLATI ON – TW I N AXLE
This m anual describes t he general installat ion and use of t he m anoeuvring syst em for single axle caravans.
When you use t he m anoeuvring system for a t win axle caravan, please check t he following:
Perm issible overall weight twin axle ( 2 m ot ors)
1800kg ( 1500kg on 18% gradient )
Perm issible overall weight twin axle ( 4 m ot ors)
2500kg ( 1800kg on 18% gradient )
2 m ot ors:
The procedure for installing a 2 m ot ors m anoeuvring system on a t win axle caravan is t he sam e as for a single
axle caravan. The elect ronic cont rol unit ( 4) only m ust be prepared for t win axle use:
Turn off t he bat t ery power isolat ion swit ch and m ove t he single/ twin axle function swit ch ( Fig 3S/ T) on the
control unit to the twin axle position ( Fig. 3T) , so that the m anoeuvring system can be used for a twin axle
caravan. I n t he t win axle funct ion when m aking curves, all wheels will drive but at a different speed.
