Ref: EM203-UM-EAL-0211-Rev.D.
Always be aware that the manoeuvring system increases the weight of your caravan or trailer. So this
reduces the payload of the Caravan.
Only use on single axle caravans or trailers.
Always make sure that the rollers are fully disengaged from the tyres when the manoeuvring system is
not in use. This is better for the tyres and for the manoeuvring system.
Always make sure that the rollers are fully disengaged before towing/moving the caravan by vehicle or
manpower. This can damage the tyres, manoeuvring system and the towing vehicle.
Always make sure that after you have finished using the manoeuvring system, the battery power
isolation switch (29) is switched off and the key is removed and stored in a safe place (out of reach of
children or other unauthorised people). If you don’t switch off, the battery will be discharged by the
small ”standby” current.
Always make sure that the remote control stored in a safe place (out of reach of children or other
unauthorised people).
Do not rely on the manoeuvring system to act as a brake.
Always apply the handbrake after manoeuvring, before disengaging the drive rollers from the tyres.
Do not use the manoeuvring system as a support when jacking up the caravan, since this can damage
the drive unit.
Do not exceed the total safe working load of 1800Kg laden weight (caravan including load).
Depending on the weight of the caravan, the manoeuvring system cannot overcome all obstructions
without assistance. Please use wedges as a ramp.
All wheels and tyres on the caravan must be of the same size and design. If tyres are worn or new
tyres are fitted, the distance between the drive rollers and the tyres may need readjusting (see

Installation - Mechanical Components

).
Sensitive objects such as cameras, DVD-Players etc. Must not be kept in the stowage box near the
control unit or the motor cable. They can be damaged by the electromagnetic fields.
Do not make any modifications on the caravan manoeuvring system (mechanical or electronically).
This can be very dangerous! No warranty claim will be accepted and we cannot guarantee the function
of the manoeuvring system if any modifications are made. We will not be liable for any damage
whatsoever caused as a result of incorrect installation, operation or modification.
OPERATION - MOTOR UNITS
The en

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.

In order to engage the rollers, fit the end socket of the engagement tool (6) on the spindle (Fig. 9) on the right
or left drive unit and turn the handle (Fig. 10).
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.
x
If the pointer is in the yellow area – Rollers are not touching or depressing the tyre sufficiently.
x
If the pointer is in the green area – Rollers should be connecting correctly to the tyre (margin of 15mm)
x
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.
