OPERATION – MOTOR UNITS
The manoeuvring system has two motor units (1 & 2). In general they are mounted in front of the axle of the
caravan. Both units are identical but cannot be switched.

Traction indicator label:
The yellow-green-red traction indicator label (Fig. 11A), on the side of each motor unit indicates if the roller is
depressing the tyre sufficiently to provide adequate traction.
 If the pointer is in the yellow area – Rollers are not touching or depressing the tyre sufficiently.
 If the pointer is in the green area – Rollers should be connecting correctly to the tyre (margin of 15mm).
 If the pointer is in the red area – Rollers are connected to the tyre but in an extreme position. It could be
that the tyre of the caravan has insufficient air pressure or the drive unit has been knocked out of position
and a visit to a workshop is required to reposition the assembly.
Disconnect the motor powered rollers in case of emergency:
In the case that the caravan battery is discharged too far to automatically take of the motor powered rollers of
the tyre, or there is a defect, you can also do this manually.
Take the plastic cap (Fig. 9B) at the rear side of the housing of the motor for the automatic engaging system.
If necessary use a screwdriver. Place the emergency key (6) on the emergency socket in the motor unit (Fig.
9A & 9.1C) and turn it until the motor unit including motor powered rollers are in the beginning position. Repeat
this also on the motor unit on the other side.
Put the plastic caps back on the motor housing.
As soon as the battery is charged again, or the problem is solved, the motor powered rollers automatically work
again.
OPERATION – REMOTE HANDSET
The remote handset (5) is powered by one PP3 9 Volt battery, and is activated by moving the slide switch to
"On"-I (Fig. 5A). Once activated the green LED (Fig. 5H) will illuminate and the directional controls can now be
used.

K. Blue LED: reflects status of the automatic engaging system
L. Red overload LED: Amp overload protection is activated. Wait about 60 seconds and try again.
M. Blue 9 Volt battery LED: The internal 9 Volt battery of remote handset is near empty and needs to be
replaced
N. Blue battery voltage LED: Caravan battery voltage too low or too high
When you drive straight forwards or reverse (press button B or C), it is also possible to adjust the direction by
additional pressing button D or E (when driving forwards) or button F or G (when driving reverse).
In addition, the 'right forward' (E) and 'left reverse' (F) buttons or 'left forward' (D) and 'right reverse' (G)
buttons may be pressed at the same time to turn the caravan around on its own axis without moving forward or
backward (this function just can work under the "single-axle function").
When you switch within 2 seconds from forward driving to reverse driving (and the other way around), a small
delay of 1 second will appear to protect the electronics and the motors.
