It is, of course, impossible for a twin-axle caravan to be manoeuvred in the same way as a single-axle as the turning
circle is greatly increased compared to a single-axle caravan. Also, the amount of different manoeuvres required to
locate/park your caravan is increased.
However, the advanced electronics of the Quattro® electronics take care of the manoeuvring whilst also taking care of
your caravan.
For example:
When the caravan is turning, the motors provide lower rotational speed on one side to help enable direction
change. This enables the caravan to manoeuvre with minimal tyre ‘scrub’ or being dragged along the ground,
which can cause undue stresses on its tyres, wheel hubs and chassis.
It is also a possibility that when operating a two motor twin-axle system, on very uneven ground, one of the wheels
driven by the mover will not make adequate contact to continue progress. If this occurs, you will need to move the
caravan in a different direction until adequate traction is regained.
Note:
Try operating the mover with the handset in both single axle and twin axle mode. Sometimes the performance on
a four motor system is actually better with all four motors operating in single axle mode. Stick with whatever mode is
most suitable for your needs.

Single Axle and Twin Axle Modes -
Important Guidelines for Set Up of a Four Motor System
It is important that this procedure be understood and followed before you start to operate a four motor caravan
mover system.
The electronics that are supplied with all Purple Line caravan movers are Quattro electronics. These are designed in
such a way that they can operate in two different modes - single and twin axle mode.
The electronics come set in single axle mode as standard. This means that you can operate the handset with all buttons
individually and you can also hold down opposite corners to get one motor going in one direction and the other going in
the opposite direction. This is ideal for single axle caravans. You will not need to do anything with the electronics if you
have installed a single axle system with two motors, just use it as it comes.
However, if you have set up a four motor system then some simple changes are required.
To enable TWIN AXLE MODE you must remove one of the AAA batteries from the handset that you have paired to the
two receiver units. Once this is removed hold down button G on the handset, keep it held down and replace the battery.
The handset will sound double beeps. Keep the button held down until you hear a long beep and the beeping stop.
Once the beeping stops that handset is then set in twin axle mode.
When in twin axle mode you cannot hold down opposite corner buttons to get the caravan to turn. If you hold opposite
corner buttons at the same time, nothing will happen at all. Instead, when in twin axle mode you can only use one
button at a time. Each button, when pressed individually, will enable the caravan to move and turn in the specified
direction. When performing a turn the outside motors will turn at full speed, while the inside motors will turn in the same
direction at a slower speed. This enables a more gradual turn, thus reducing tyre scrub.
Twin axle mode should be the default set-up on a twin axle caravan.
To enable SINGLE AXLE MODE, repeat the above process, but hold down button E on the handset. This time you will
hear single beeps. Hold the button down until the beeps stop. The handset is now set in single axle mode.
You can use a four motor system in single axle mode, and it may be worth trying out both modes to see which mode
works best for you. You can quickly and easilly change between the two modes by following the above procedure.
Battery Set Up When Using Four Motors
It is strongly advised that when using four motors you also use two batteries. This is in order to maximise the
performance of your mover.
When setting up the two batteries, first connect the two batteries together. Once this is done connect the positive
