INTRODUCTION
Congratulations on choosing the emove 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 emove 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 emove 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. 2.5mm 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 .
EM303A Manual AW 2019.qxp_Layout 1 23/12/2019 15:53 Page 5

Check the minimal installation dimensions of the manoeuvring system based on figure 14.
Only use adapters and accessories that are supplied or recommended by the manufacturer.
Check that the caravan is disconnected from the battery supply and the mains electrical supply.
Check that the tyres are not over worn and do have the same size and design (fitting to new or nearly new
tyres is the best option).
Make sure that the tyre-pressures are correct to the recommendation.
Make sure the chassis is in good condition without any damage and is free from rust, dirt etc.
Stop work immediately if you are in doubt about the assembly or any procedures and consult one of our
engineers (Please refer to contact information on the last page of this manual).
Locate the battery isolation switch to be accessible at all times when parking and moving the caravan.
Do not remove, change or alter any parts of the chassis, axle, suspension or brake mechanism. Any drilling of
holes in the chassis is not allowed.
Do not install the unit if you are under the influence of drugs, alcohol or medication that could impair your
ability to use the equipment safely.

These
instructions
are
for
general
guidance.
Installation
procedures
may
vary
depending
on
caravan
type.
Working
under
a

without
appropriate
support
is
extremely
dangerous!
Please
refer
to
figure
13
for
an
overview
of
the
whole
assembly
fully
fitted.
Place the caravan on ahard, level surface. The use of alifting ramp or an assembly pit is ideal for access and
personal safety.
Unpack all the components and check for the presence of all parts (see package contents list). Write down, on
the product warranty registration card, the 10-digit serial number (this is located on an aluminium plate on the
side of one of the motor units).
Clean the area of your chassis where you need to mount all components to ensure agood fitting.
Make sure the caravan is prepared for installation. Check before installation that important areas, such as
drains/spare tyre etc. do not cause any obstruction to the function of the caravan manoeuvring system.
Ensure both rollers are in the DISENGAGED position (Fig. 10), as the unit will not fit correctly otherwise (Note:
when fully disengaged, the pointer is positioned in the beginning of the yellow area).
Loosely assemble the left hand motor unit (1), right hand motor unit (2) and main cross bar (3) (Fig. 1). The
nuts (Fig. 1A), on the cross bar (3) to secure both motor units, must be no more than finger-tight at this stage.
Note
:In principle, the unit should be fitted in front of the caravan road wheels, but if fitting in this position is
not possible because of obstacles or atoo high hitch ball weight, it is permissible to fit it to the rear of the
wheels by rotating the whole assembly (Fig. 1) by 180° degrees.
Loosely fit the two clamping assemblies (7) to the chassis (Fig. 2&13) and attach. Use the bolts M10x60, nuts
M10 and washers M10 (8,17,18) and put them in the diagonal positioned holes of the aluminium chassis clamp
plates. Nuts must be no more than finger-tight.
Assemble the pre-mounted manoeuvring system on the aluminium chassis clamp plates by using the two U-
shaped brackets (9), bolts M10x50, nuts M10 and washers M10 (16,17,18). Nuts must be no more than finger-
tight.
Make sure that aluminium drive rollers of the motors are approximately on the same altitude as the centre
(axle) of the caravan wheel (0mm~40mm, see Fig. 10). As well make sure that between the top of the motor
housing and the floor of the caravan is minimal 20mm space to make sure the motors can move freely (see Fig.
10 &15). To compensate apossible unevenness (and lower the motors), emove has aset of distance plates
available. One set can compensate 15mm. In total three sets can be used so that an altitude of 45mm can be
compensated.

Make sure that the main cross bar (3) is positioned in the middle of the caravan (the centre of the bar is
marked).
With the main assembly is loosely fitted onto the chassis, slide the whole assembly along the chassis until the
rollers are 20mm away from the surface of the centre each tyre (Fig. 10). Two 20mm spacers (30) are provided.
It
is
vitally
important
that
each

there
is
sufficient
space
available
(minimal
20mm)
between
the
top
of
the
motor
housing
and
the
floor
of
the

can
move
freely
(Fig.
15).
Fully tighten the four bolts (Fig. 1A) on the main cross bar (3) and
lock them by
the additional nuts.
Fully tighten all the nylon nuts on both clamping assemblies (Fig. 2). First tighten the diagonal placed M10x60
bolts with a20Nm torque, and then M10x50 bolts to a40Nm torque.
Re-check the distance of 20mm from the rollers to the tires, the position of the aluminium rollers in addition to
the surface of the tire and finally the distance between the gear cover (Fig. 8) and the tires &shock absorbers
(>10mm). The weight of the caravan must be on the wheels when doing this. If necessary, loosen the bolts and
re-adjust the position of the assembly.
Re-check
that
all
bolts/nuts
have
been
tightened
to
the

Mark the motor cables (12 & 13) for both motor units using the cable markers (25). The cables for the left and
the right motor should have the same length. Avoid any loops.
Connect the spade connectors to the motors. Please note that the red cable is connected to the terminal under
the moulded ‘+’ symbol on the weatherproof terminal cover.
Remember to leave a small amount of slack cable near the motors to allow for their movement when the drive
rollers are engaged.
Route all the cables along the underside of the caravan floor, inside the supplied convoluted trunking (11) (this
will protect the electrical cables against sharp edges and dirt) and through the drilled hole.
Secure the cable trunking (11) to the chassis or under body of the caravan by using the P-Clips (20) and screws
(19).
Once the all cables are through the drilled hole next to the control unit (4), cut the cables, ensuring that they
are the same length. Remove approx. 5mm of the insulation from the ends. Fix the big spade fork connectors
(24) to the motor cables and the small spade fork connectors (34) to the automatic-engaging-cables by using
crimping pliers. A secure and good quality connection on each cable is essential.
Attach the spade fork connectors to the terminals on the control unit (see wiring diagram Fig. 12) and fix them
tightly by the screws. A safe and good quality connection on each cable is again essential.
Find a suitable place for the battery power isolation switch (29) which includes an external holder with hinged
cover.
Important: The switch must be mounted onto the exterior body of the caravan and be easily
accessible from the outside of the caravan in case of any emergency.
The switch must be mounted close
to the location of the battery in order to keep the length of the battery cables to a minimum.
Use the cardboard template to position the hole positions and the drill holes. Mount the switch and the housing
with the bolts, washers and nuts, and finally mount it on the caravan with stainless steel screws (19).
Route the positive (+) power cable (including fuse) from the battery to the battery power isolation switch (29)
and than further to the control unit (4).
The electronic connections of the battery power isolation switch (29) must be covered by the supplied rubber
isolation shells (31).
Route the negative (-) power cable directly to the control unit (4).
No cables may be routed over the control unit!
Again it is recommended to use the supplied trunking (11) to protect the cables against sharp edges. Attach the
trunking with P-clips (20) and P-clip screws (19).
Cut the cables to an appropriate length and remove approx. 5mm of the insulation from the ends. Fix the
battery terminal connectors by using crimping pliers. Two types of battery terminal connector (22 & 23) are
provided for use as appropriate. A secure and good quality connection on each cable is essential.
Connect the battery cables (14 & 15) to the control unit (4): Attach the spade fork connectors to the positive
(+) en negative (-) terminal of the control box and fix them tightly by the screws.
Connect the battery cables to the existing battery terminals (red = positive, black = negative).
EM303A Manual AW 2019.qxp_Layout 1 23/12/2019 15:53 Page 8

Caution! Make sure that you do not reverse the Positive (+) and Negative (-) connections.
Incorrect connection (reverse polarity) will result in damage to the control unit.
Connect the battery cables (14 & 15) to the control unit (4).
Seal the 25mm hole in vehicle under body using plastic body sealant.
Installation of the caravan manoeuvring system is now complete.
INSTALLATION – TWIN AXLE
This manual describes the general installation and use of the manoeuvring system for single axle caravans.
When you use the manoeuvring system for a twin axle caravan, please check the following:
Permissible overall weight twin axle (2 motors) 1800kg (1500kg on 18% gradient)
Permissible overall weight twin axle (4 motors) 2500kg (1800kg on 18% gradient)
2 motors:
The procedure for installing a 2 motors manoeuvring system on a twin axle caravan is the same as for a single
axle caravan. The electronic control unit (4) only must be prepared for twin axle use:
Turn off the battery power isolation switch and move the single/twin axle function switch (Fig 3S/T) on the
control unit to the twin axle position (Fig. 3T), so that the manoeuvring system can be used for a twin axle
caravan. In the twin axle function when making curves, all wheels will drive but at a different speed.
4 motors:
The procedure for installing a 4 motors manoeuvring system on a twin axle caravan is similar than for a single
axle caravan but then with two sets of manoeuvring system.
Follow the procedure for
installing the mechanical components
twice: one time for the manoeuvring set
mounted in front of the twin axle and one time for the manoeuvring set mounted behind the twin axle.
Follow the procedure for
installing the electrical/electronic components
twice: one time for the
manoeuvring set mounted in front of the twin axle and one time for the manoeuvring set mounted behind the
twin axle.
Note:
When installing the four motors it will be necessary to use
one
higher capacity battery to supply both
sets of manoeuvring system (including two electronic control units and two of battery power isolation switches).
Do not use two separate batteries for a 4 motors manoeuvring system on a twin axle caravan.
Now
both
electronic control units (4) must be prepared for twin axle use:
Turn off the battery power isolation switch and move the single/twin axle function switch (Fig 3S/T) on the
control unit to the twin axle position (Fig. 3T), so that the manoeuvring system can be used for a twin axle
caravan. In the twin axle function when making curves, all wheels will drive but at a different speed.
Finally both electronic control units (4) must be prepared for the use of only one remote handset (32). The
remote handset need to be synchronised with both electronic control units using the following procedure:
Check the installation in accordance with the installation instructions and ensure that the drive rollers are
not applied. Check that the battery is properly connected, check the condition of the battery and that a
voltage of 12V is present at the control unit.
Please ensure that both battery isolation switches are on.
Activate the remote control handset by sliding the slide switch to “On”-I (Fig. 5A). The green LED on the
remote control handset (Fig. 5H) starts to flash slowly.
Press the reset button (Fig. 3A) on the control unit. All three LED’s on the control unit (Fig. 3B, 3C & 3D)
will flash slowly.
Press both forwards (Fig. 5B) and reverse (Fig. 5C) button on the remote control handset for about 3
seconds. Then the handset buzzer will give a short beep to confirm that the synchronisation is complete.
After successful synchronisation, the green LED on the control unit (Fig. 3B) and on the remote control
handset (Fig. 5H) will illuminate continuously.
Repeat this procedure with the second electronic control unit.
Turn the remote handset “Off” and then “On” again so both control units will be activated.
The installation of the caravan manoeuvring system for twin axle use is now complete. For details of the
operation, use and all the LED and button functions, please refer to the standard chapters of this manual.

SAFETY
GUIDELINES
Practice operating the manoeuvring system in an open area before using for the first time. This is to fully
familiarise yourself with the handset /manoeuvring system operation.
Before use, always check the caravan manoeuvring system for any damage.
When towing or moving the caravan please be aware, at all times, that ground clearance is reduced
when the manoeuvring system has been fitted.
Always ensure that children and pets are kept well out of the way during operation.
When operating the system, ensure that no hairs, fingers or other body parts, clothing or any other
objects carried on the body can become trapped by moving or rotating parts (e.g. drive rollers).
In the event of malfunctions, pull on the handbrake immediately and turn off the main isolation power
switch.
To maintain signal strength, always make sure that, during manoeuvring, the distance between the
remote control and the caravan does not exceed 5
metres.
Due to the nature of aradio signal, it can get corrupted by external terrain or objects. So there may be
small areas around the caravan where the quality of reception reduces, hence the manoeuvring system
may stop momentarily.
Always be aware that the manoeuvring system increases the weight of your caravan or trailer. So this
reduces the payload of the caravan.
Do not exceed the total safe working load of 1800kg laden weight (caravan including load) when 2
motors are used and 2500kg laden weight (caravan including load) when 4
motors (twin axle) are used.
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 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 asafe place (out of reach of
children or other unauthorised people). If you switch off, the battery will be discharged by the
small current.
Always make sure that the remote control handset is switched off and stored (in the wall holder) in a
safe place (out of reach of children or other unauthorised people). If you switch off, the battery
will be discharged by the small current.
Do not rely on the manoeuvring system to act as abrake.
Always apply the handbrake after manoeuvring, before disengaging the drive rollers from the tyres.
Do not use the manoeuvring system as asupport when jacking up the caravan, since this can damage
the drive unit.
Depending on the weight of the caravan, the manoeuvring system cannot overcome all obstructions
without assistance. Please use wedges as aramp.
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
-Mechanical
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 system if any modifications are made. We will not be liable for any damage whatsoever caused
as aresult of incorrect installation, operation or modification.

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 avisit to aworkshop is required to reposition the assembly.
Disconnect
the
motor
powered
rollers
in
case
of
emergency:
In the case that the caravan battery is discharged to far to automatically take of the motor powered rollers of
the tyre, or there is adefect, you can also do this manually. See figures 9&9.1.
Tak e the plastic cap (Fig. 9B) at the rear side of the housing of the motor for the automatic engaging system.
If necessary use ascrewdriver. 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.
