INTRODUCTION
Congratulations on choosing the emove EM303A caravan maneuvering 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 allow you to maneuver your caravan even more accurately without any shocks.
The caravan maneuvering 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 tires of your caravan. The emove EM303A caravan maneuvering 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 tire. Once this is done the maneuvering 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 orbackward (this function just can work under the “single-axle function”).
Before proceeding with installation and starting to use the maneuvering 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 maneuvering 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 maneuvering 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 maneuvering 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 maneuvering system tself has a weight of about 34kg and a traditional lead-acid battery has a weight of about 20-25kg.
Check the minimal installation dimensions of the maneuvering 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 tires are not overworn and do have the same size and design (fitting to new or nearly new tires 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.
INSTALLATION – MECHANICAL COMPONENTS
|
FOR PROFESSIONAL INSTALLATION ONLY! These instructions are for general guidance. Installation procedures may vary depending on caravan type. |
|
Working under a vehicle without appropriate support is extremely dangerous! |
Please refer to figure 13 for an overview of the whole assembly fully fitted.
Place the caravan on a hard, level surface. The use of a lifting 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 aluminum 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 a good fitting.Make sure the caravan is prepared for installation. Check before installation that important areas, such as drains/spare tires, etc. do not cause any obstruction to the function of the caravan maneuvering 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 at the beginning of the yellow area).Loosely assemble the left-hand motor unit (1), right-hand motor unit (2), and main crossbar (3) (Fig. 1). The nuts (Fig. 1A), on the crossbar (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 a too-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 diagonally positioned holes of the aluminum chassis clamp plates. Nuts must be no more than finger-tight.Assemble the pre-mounted maneuvering system on the aluminum 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 the aluminum drive rollers of the motors are approximately at the same altitude as the center (axle) of the caravan wheel (0mm~40mm, see Fig. 10). As well as 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 for a possible unevenness (and lower the motors), emove has a set of distance plates available. One set can compensate for 15mm. In total three sets can be used so that an altitude of 45mm can be compensated.
Adequate ground clearance: Please notice that the min. distance between the lowest line of motors and ground is 110mm, no matter what kind of chassis or install situation.
Make sure that the main crossbar (3) is positioned in the middle of the caravan (the center 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 center of each tire (Fig. 10). Two 20mm spacers (30) are provided.
|
It is vitally important that each roller is at exactly the same distance away from the tire. The whole assembly must be parallel to the caravan/trailer axle. |
|
Slide the motor units in or out of the crossbar (3) accordingly to ensure the roller will have the maximum possible contact with the tread of the tire. Ensure that the position of each motor unit does not obstruct shock absorbers (if fitted) and that the gear cover (Fig. 8) is not too close to the surface of the tire/shock absorber. The minimum clearance when the drive units swiveled in is 10mm. |
|
Re-check that there is sufficient space available (minimal 20mm) between the top of the motor housing and the floor of the caravan so the motors can move freely (Fig. 15). |
Fully tighten the four bolts (Fig. 1A) on the main crossbar (3) and lock them with the additional nuts.Fully tighten all the nylon nuts on both clamping assemblies (Fig. 2). First, tighten the diagonal placed M10x60 bolts with a 20Nm torque, and then M10x50 bolts to a 40Nm torque.Re-check the distance of 20mm from the rollers to the tires, the position of the aluminum 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 correct torque!
The main mechanical components have now been installed.
INSTALLATION – ELECTRICAL/ELECTRONIC COMPONENTS
Make sure the 12V supply from the battery and any 230V electricity supply are disconnected.
Remove battery cable terminals and disconnect any external electrical power before starting work.Find a suitable place for the electronic control unit (4), such as a storage area, under a seat, or a bed. Make sure this place is dry and close to the battery (40cm to 60cm). The electronic control unit can be mounted vertically on a side wall or be mounted flat. When mounted vertically, the connections must point downwards to avoid any short-circuits by objects falling into.Fix the electronic control unit securely into position with two screws M5x40 (33). Note: if the provided screws are not of suitable length or type for the desired location/material please substitute these as appropriate.Drill a 25mm hole through the floor of the caravan approximately 150mm centrally in front of the control unit (4) terminals.
Caution! Take extra care to avoid any chassis members, gas pipes, and electrical wires!
Route and connect the motor cables in accordance with the wiring diagram (Fig. 12) (red = positive, black = negative).The wiring diagram (Fig. 12 + Tab le. A (see below)) depicts the wiring route when installing the motor units in front of the wheels/axle towards the frame. Please refer to table B (below) for the fitment of the motor units to the rear of the axle.

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 underbody 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 with 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 a 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 then 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 connectors (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 with the screws.Connect the battery cables to the existing battery terminals (red = positive, black = negative).
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 the vehicle under the body using a plastic body sealant.Installation of the caravan maneuvering system is now complete.
INSTALLATION – TWIN AXLE
This manual describes the general installation and use of the maneuvering system for single axle caravans.When you use the maneuvering 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 maneuvering 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 maneuvering 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 maneuvering system on a twin axle caravan is similar to for a single axle caravan but then with two sets of maneuvering systems.Follow the procedure for installing the mechanical components twice: one time for the maneuvering set mounted in front of the twin axle and one time for the maneuvering set mounted behind the twin axle.Follow the procedure for installing the electrical/electronic components twice: one time for the maneuvering set mounted in front of the twin axle and one time for the maneuvering 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 maneuvering systems (including two electronic control units and two battery power isolation switches).Do not use two separate batteries for a 4 motors maneuvering 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 maneuvering 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 needs to be synchronized 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 LEDs 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 synchronization is complete.After successful synchronization, 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 maneuvering 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.
OPERATION – SAFETY GUIDELINES
Practice operating the maneuvering system in an open area before using for the first time. This is to fully familiarise yourself with the handset/maneuvering system operation.
|
Before use, always check the caravan maneuvering system for any damage. |
|
When towing or moving the caravan please be aware, at all times, that ground clearance is reduced when the maneuvering 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 maneuvering, the distance between the remote control and the caravan does not exceed 5 meters. |
|
Due to the nature of a radio 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 maneuvering system may stop momentarily. |
|
Always be aware that the maneuvering 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 tires when the maneuvering system is not in use. This is better for the tires 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 tires, maneuvering system, and the towing vehicle. |
|
Always make sure that after you have finished using the maneuvering 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 unauthorized 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 unauthorized people). If you switch off, the battery will be discharged by the small current. |
|
Do not rely on the maneuvering system to act as a brake. |
|
Always apply the handbrake after maneuvering, before disengaging the drive rollers from the tires. |
|
Do not use the maneuvering system as support when jacking up the caravan, since this can damage the drive unit. |
|
Depending on the weight of the caravan, the maneuvering system cannot overcome all obstructions without assistance. Please use wedges as a ramp. |
|
All wheels and tires on the caravan must be of the same size and design. If tires are worn or new tires are fitted, the distance between the drive rollers and the tires may need readjusting (see – Mechanical |
|
Sensitive objects such as cameras, DVD-Players, etc. Must not be kept in the storage box near the control unit or the motor cable. They can be damaged by electromagnetic fields. |
|
Do not make any modifications to the caravan maneuvering 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 a result of incorrect installation, operation, or modification. |
OPERATION – MOTOR UNITS
The maneuvering 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 tire sufficiently to provide adequate traction.
- If the pointer is in the yellow area Rollers are not touching or depressing the tire sufficiently.
- If the pointer is in the green area Rollers should be connecting correctly to the tire (margin of 15mm).
- If the pointer is in the red area Rollers are connected to the tire but in an extreme position. It could be that the tire 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 to far to automatically take of the motor-powered rollers of the tire, or there is a defect, you can also do this manually. See figures 9 & 9.1.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 CONTROL HANDSET
The remote control handset (5) is powered by one PP3 9Volt battery and is activated by moving the slide switch to -I (Fig. 5A). Once activated the green LED (Fig. 5H) will illuminate and the directional controls can now be used.

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 (E) and (F) buttons or (D) and (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 -axleWhen 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.
The slide switch (Fig. 5A) also acts as an
The automatic engaging system:To activate the automatic engaging system of the motor-powered rollers on the tire, press the two buttons for engaging (Fig. 5I) or disengaging (Fig. 5J) for at least three seconds. The blue LED (Fig. 5K) will blink fast during these three seconds and every second there will be a beep. This warns you that the system will be activated!Engaging: After these three seconds the motor-powered rollers will be pressed against the tire, and the blue LED will illuminate constantly. Now you can release the two buttons. When the motor-powered rollers are pressed on the tire strongly enough you hear a short beep, the blue LED will switch off and the system is ready to use.Disengaging: after these three seconds the motor-powered rollers will be released from the tire, and the blue LED will illuminate constantly. Now you can release the two buttons. When the motor-powered rollers are completely disengaged you hear a short beep, the blue LED will switch off, and is the system ready for transport.
The remote handset switches off:After 3 minutes, if no button is pressed: After 2 minutes the buzzer will beep 5 times with a repetition after 3 minutes. Then the system switches in the – modes.After 6 minutes, if one of the movement buttons is permanently held down: After 5 minutes the buzzer will beep for 5 times with a repetition after 6 minutes. Then the system switches in the – modes.The green LED goes off and the remote control handset is in the – modes which mean that there always will be used some current which causes the battery to go down. So always make sure the remote control handset is turned off by the slide switch.To reactivate the remote control, move the slide switch to O and then back to -I after approximately 1 second.
Error messages via the remote control handset:Error messages of the emove EM303A will be communicated via the remote control handset by the green LED (Fig. 5H), the error message (Fig. 5L, 5M & 5N) and a buzzer signal:Green LED (Fig. 5H) off, no buzzer: remote control handset is turned off and also the system is not activated Green LED (Fig. 5H) continue on, no buzzer: remote control handset is turned on and the system is activated and ready to use.Green LED (Fig. 5H) is blinking, no buzzer: no communication between handset and control unit. This could be because of too much distance between the remote control handset and control unit, or the battery isolation switch for the maneuvering system is not turned on, or that there is a distortion signal disturbing the communication. As soon as the connection is good again the green LED will continue on and the system is ready to use.Blue battery voltage LED (Fig. 5N) is blinking in combination with a buzzer (2 times blinking, break, 2 times blinking, break, etc.): Battery voltage too low (<10V). The battery needs to be recharged.Blue battery voltage LED (Fig. 5N) is blinking in combination with a buzzer (4 times blinking, break, 4 times blinking, break, etc.): Battery Voltage too high (overcharged). Try to discharge the battery by turning on a user (for example a lamp or water pump).Red overload LED (Fig. 5L) is blinking in combination with a buzzer (6 times blinking, break, 6 times blinking, break, etc.): Amp overload protection is activated. Wait about 60 seconds and try again.Blue 9V battery LED (Fig. 5M) is blinking, no buzzer: The internal 9V battery is near empty and needs to be replaced.
Changing batteries in the remote control:When the battery is empty (blue 9V battery LED (Fig. 5M) is blinking), it needs to be replaced.
- Open the rear cover of the handset (Fig. 7A).
- Take out the dead/old battery and dispose of in the appropriate way.
- Install a new replacement battery (Fig. 7.1). Make sure to use a leak-proof PP3 (9Volt) battery (No claims under guarantee can be considered for damage caused by leaking batteries).
- Close the rear cover again.
Dead and used batteries may leak and damage the remote control handset! Remove the batteries if the handset is not going to be used for an extended period.
OPERATION – ELECTRONIC CONTROL UNIT
The electronic control unit (4), which is mounted inside your caravan, is responsible for controlling the maneuvering system.The control unit has three one pushbutton and one slide switch (Fig. 3):Green LED (Fig. 3B): Power LED continuously illuminated when the system is activated (by moving slide switch to -I). If the handset far away from the control unit, beyond the available distance, this LED will go out.Blue LED (Fig. 3C): Error message LED concerning caravan battery:
- Blue LED is blinking (2 times blinking, break, 2 times blinking, break, etc.): Battery voltage too low (<10V).The battery needs to be recharged.
- Blue LED is blinking (4 times blinking, break, 4 times blinking, break, etc.): Battery Voltage too high (overcharged). Try to discharge the battery by turning on a user (for example a lamp or water pump).
Red LED (Fig. 3D) is blinking (6 times blinking, break, 6 times blinking, break, etc.): Amp overload protection is activated. Wait about 60 seconds and try again.In general, all error messages will reset automatically after one minute. If this is not the case, reset the electronics of the maneuvering system by switching off the system via the isolation switch and the remote control handset for at least 15 seconds and then turning it on again.The Reset Button (Fig. 3A): The remote control handset and the control unit are synchronized with each other in the factory. If the control unit or the remote control handset is replaced, they must be re-synchronised as described below:
- 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 12 V is present at the control unit.
- Please ensure that the battery isolation switch is on.Activate the remote control handset by sliding the slide switch to -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 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 synchronization is complete.
- After successful synchronization, the green LED on the control unit (Fig. 3B) and on the remote control handset (Fig. 5H) will illuminate continuously.
The single-twin axle function switch (Fig. 3S/T): The emove EM303A caravan maneuvering system is suitable for both single axle and twin axle caravans. You just need to pull the single-twin axle function switch (Fig 3S/T) on the control unit, so that the maneuvering system can be used for a single-axle caravan or a twin-axle caravan (for 2 motor use but also for 4 motor use). In the twin axle function, all wheels will drive but at a different speed.The switch standard is pre-selected for single axle use (Fig 3S). For twin axle use, just move the switch to the twin axle position (Fig. 3T). When moving the single-twin axle function switch, the battery power isolation switch (29) must be turned off.

Now you can release the two buttons. When the motor-powered rollers are pressed on the tire strongly enough, the blue LED will switch off and is the system ready to maneuver. The color of the traction indicator label (Fig. 11A) should be in the green area.Before operating the maneuvering system, release the handbrake.Now you can choose the movements according to the symbols shown on the remote control. Straight forward (Fig. 5B), straight reverse (Fig. 5C), left forward (Fig. 5D), left reverse (Fig. 5F), right forward (Fig. 5E), right reverse (Fig. 5G).
In addition, the left forward (Fig. 5D) and right reverse (Fig. 5G) buttons or right forward (Fig. 5E) and left reverse (Fig. 5F) 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 -axle When you drive straight forwards or reverse (press button 5B or 5C), it is also possible to adjust the direction by additional pressing button 5D or 5E (when driving forwards) or button 5F or 5G (when driving reverse).Because of the technology, the caravan will slowly speed up. Because of the technology, the caravan will stop slowly. This allows you to maneuver your caravan even more accurately without any shocks.
|
WARNING: When the buttons on the remote control handset are released, the caravan will slowly stop after 0.5 second and continue to move about 6cm (depending on final speed).When the buttons of the remote control handset are released when the system is still in the stage (slowly speed up), the caravan will stop immediately. |
After the stage, the caravan moves according to one fixed speed. The speed can increase a little when going downhill and decrease a little when going uphill.TIP: The maneuvering system is more efficient when reversing the caravan up an incline.
|
When you are ready with maneuvering you need to secure the handbrake. |
Press at the same time, during at least three seconds, the two buttons for disengaging the motor-powered rollers (Fig. 5J). The blue LED (Fig. 5H) will blink fast during these three seconds and every second there will be a beep. This warns you that the system will be activated!After these three seconds, the motor-powered rollers will be released from the tire and the blue LED will illuminate constant, now you can release the two buttons. When the motor-powered rollers are completely disengaged the blue LED will switch off and the system is ready for transport.After maneuvering, deactivate the maneuvering system by moving the slide switch to -O on the remote control handset (Fig. 5A). The green LED (Fig. 5H) on the remote control handset will turn off. Store remote control in a safe place (out of reach of children or other unauthorized people).
