It is vitally important that each roller is at exactly the same distance away from the tyre. The whole
assembly must be parallel to the caravan/trailer axle.
Slide the motor units in or out of the cross bar (3) accordingly to ensure the roller will have the maximum possible
contact with the tread of the tyre. Ensure that the position of each motor unit does not obstruct shock absorbers (if
fitted) and that the transmission gear guard (Fig.4f) has a minimum distance of 10mm to the inner surface of the tyre
when the mover is engaged (Fig.6).
Fully tighten the four nylock nuts (17) on both clamping assemblies (Fig.2) to a torque setting of 40 ft lbs/55Nm, the
four bolts (Fig.1b) on the Main Cross Bar (3) and the four bolts (Fig.1c) on Cross Actuation assembly (4 & 5) to a torque
setting of 9ft lbs/12Nm. Re-check the distance of 20 mm from the rollers to the tyres and if necessary, loosen the bolts
and re-adjust the position of the assembly.
Once satisfied with the position of the assembly, fit and tighten the Chassis Stop Nuts & Bolts (7) , one pair in each of
the Upper Chassis Clamp Plates (see Fig.2). The Stop Bolts grip the lip of the chassis and help prevent the mover from
sliding along the chassis. The main mechanical components have now been installed.

Make sure the 12V supply from the battery and any 230V electricity supply are disconnected.
Find a suitable place for the Electronic Control Unit (32), such as a storage area, under a seat or a bed. Make sure this
place is dry and close to the battery (30 cm to 60 cm). The unit can be mounted on the bottom (horizontal) or on the wall
(vertical). When choosing location, ensure that the antenna can be completely extended and cannot easily be damaged.
Fix the Electronic Control Unit securely into position with four screws (19). Note: if the provided screws are not of
suitable length or type for the desired location/material please substitute these as appropriate.
Drill a 25 mm hole through the floor of the caravan approximately 150 mm centrally in front of the control unit (32)
terminals. Caution! Take extra care to avoid any chassis members, gas pipes and electrical wires!
Route and connect the motor-cables in accordance with wiring diagram (Fig.12) (red = positive, black = negative).
The wiring diagram (Fig.12 + Table.A (see below) depicts the wiring route when installing the motor units in FRONT of
the wheels/axle towards the 'A' frame. Please refer to table B (below) for 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.
Use the large cable ties (28) to secure the motor cables to the motor. This ensures that there is no force and movement
on the spade connectors or movement of the cables during transit.
Route the motor 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 motor cables are through the drilled hole next to the Control Unit (32), cut the cables, ensuring that they are
the same length. Remove approx. 5 mm of the insulation from the ends. Fix the spade connectors (24) by using crimping
pliers. A secure and good quality connection on each cable is essential.
