ENDURO® EM313A 29
Ref: EM313A-UM-TKI-0323-Rev.B.
Check the minimal installation dimensions of the manoeuvring system based on figure 1.1 and 1.2.
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 manufacturer’s 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 system if you are under the influence of drugs, alcohol or medication that could impair your
ability to use the equipment safely.
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 1.3 and 11 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 products invoice, the 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 a good 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. 13), as the system will not fit correctly otherwise
(Note: when fully disengaged, the pointer is positioned in the beginning of the yellow area).
Loosely assemble with bolts (22) and nuts (23) the left hand motor unit (1+4), right hand motor unit (2+3)
and main cross bar (5). The nuts (Fig. 1.3C), on the cross bar to secure both motor units, must be no more
than finger-tight at this stage.
Note: In principle, the system 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.
For mounting the mounting clamps (12, 14) it is important the two parts are first fitted around the base frame
(Fig. 2.1) and then loosely fit the two clamping assemblies to the chassis (Fig. 2.3 & 11) and attach. Use the
bolts M12x110, nuts M12 and washers M12 (19, 20, 21) and put them in the holes of the mounting clamps.
Bolts must be no more than finger-tight. Such that the mounting clamps can just be moved.
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. 3). As well make sure that between the top of the motor
housing and the floor of the caravan is minimal 10mm space to make sure the motors can move freely. To
compensate a possible unevenness (and lower the motors), a set of ENDURO® distance plates is added (13, 15).
One set can compensate 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.
