INTRODUCTION
Congratulations on choosing the EN
DURO
®
EM303A
+
caravan manoeuvring system. This has been produced
according to very high standards and has undergone careful quality control procedures.
Simply by using the remote control handset you can move your caravan effortlessly into any position required
within operating guidelines. Soft start and soft stop technology allows you to manoeuvre your caravan even
more accurately without any shocks.
The caravan manoeuvring system consists of two 12V motor-power rollers, a 12V electronic control unit and a
remote control handset. To function, the motor-powered rollers must be engaged against the tyres of your
caravan. The EN
DURO
®
EM303A
+
caravan manoeuvring system is provided with an automatic engaging system.
By pushing two buttons on the remote control, both motor-powered rollers will be simply pressed on the tyre.
Once this is done the manoeuvring system is ready for operation. The remote control will allow you to move
your caravan in any direction. You can even rotate the caravan on its own axis without moving forwards or
backwards (this function just can work under the “single-axle function”).
Before proceeding with installation and starting to use the manoeuvring system, please read
this manual very carefully and be aware of all the safety instructions! The owner of the
caravan will always be responsible for correct use. Keep this manual inside your caravan for
future reference.
INTENDED USE
The EN
DURO
®
EM303A
+
caravan manoeuvring system is suitable for single axle and double axle caravans.
Suitable only for L-profiled and U-profiled chassis with a chassis thickness between min. 2.8mm and max.
3.5mm.
Depending on the weight of the caravan, the manoeuvring system cannot overcome obstructions that are more
than about 2cm in height without assistance (please use wedges as a ramp).
The standard installation kit only provides parts for installing the caravan manoeuvring system within the
measurements given in Fig. 14.

INSTALLATION – SAFETY GUIDELINES
Read this user manual carefully before installation and use. Failure to comply with these
rules could result in serious injury or damage to property.
These symbols identify important safety precautions. They mean CAUTION! WARNING!
SAFETY FIRST! IMPORTANT INFORMATION!
Before starting installation under the caravan:
Check the towing load of your vehicle and the gross weight of your caravan in order to establish whether they
are designed for the additional weight. The manoeuvring system itself has a weight of about 34kg and a
traditional lead acid battery has a weight of about 20-25kg (the by us recommended EN
DURO
®
LI1220 LiFePO4
battery weighs only 4,3kg).
