  • First check the compensating cylinders, non-return valve, ball valves, HD hoses of the lift shaft to see if there is any leakage visible externally.

    If not, there is internal leakage.

    • Check the compensation cylinders, ball valves, flow control valve, non-return valves, HD hoses for external leakage.
      Should this not be the case es there is an internal leakage.

    For air suspension:

    • Check air bellows, 5 position valve, ride height valve.
      Usually these leaks are audible, otherwise look for them with an air leak meter.

  • Raising and lowering the loading floor is only for special situations. Some examples are:

    • Passing under a low viaduct.
    • Driving on and off a ferry.
    • Loading a specific load.

    In these cases, the ride height can be lowered or raised.

    let op

    Warning!
    When lifting and lowering, only the driver should be near the vehicle combination.
    let op

    Warning!
    Be careful not to pinch any body parts.

    !

    		 Caution!
    With the loading floor in the lowered position, the maximum speed is limited to 10 km/h.

    !

    		 Caution!
    When the loading floor is in the lowered position, there is no axle compensation and no vertical axle movements are possible. Driving in these positions should be avoided as much as possible!

    !

    		 Caution!
    Before changing the height of the loading floor, check whether there is sufficient air pressure in the air reservoir.
    Note!
    To stop the loading floor in an intermediate position, the lever can be turned to position 4, see Figure 7-3.
    1. Place the vehicle combination on a level surface.
    2. Make sure there is sufficient air pressure in the air reservoir.
    3. Turn the lever from the driving position (3) to the lowering position (5). The loading floor will now lower.
    4. When the loading floor has reached the desired height, turn the lever from the lowering position (5) to the stopping position (4). The set height is ‘held’.
    5. Clear the obstacle.
    6. Place the vehicle combination on a level surface.
    7. Turn the lever from stop position (4) to travel position (3). The loading floor now rises. The driving height will automatically return to the correct driving level.

  • See handbook supplied with the vehicle.

    • Check that all intermediate cables (NATO + ISO-N + ISO-S + ABS/EBS) are connected. It is important that the above cables are all connected!
    • Check the intermediate cables for visible damage and check truck and trailer plugs and sockets. It sometimes happens that a contact pin is pushed back when connecting the intermediate cables, which means it no longer makes good contact and thus causes a malfunction.
    • Check the fuses of the manual steering (see where are the fuses of my steering).
    • Check whether the red warning lamp on the front left of the trailer is flashing. When this lamp flashes, it indicates that the ASA control board mounted in the steering box is not receiving a speed signal.
    • When all the above items have been checked and the manual steering still does not work, please contact our service workshop in Wijchen or in Zwijndrecht (NL)(D) (B) to make an appointment > schedule a service engineer.

  • Do you have a semi-trailer with or without hand steering?

    With hand steering:

    When you operate the ‘automatic centre position’ button on your remote control, the axles of the semi-trailer will automatically turn into the straight ahead position.

    Hold this button and drive your truck forward in a straight line at a walking pace.

    While doing so, look in the mirrors to assess whether you are driving straight ahead of the trailer.

    When the combination is aligned, you can release the knob.

    If you feel that the alignment is still not 100%, you can manually adjust the axles of the semi-trailer to the left or right, if required, by briefly pressing the Align Left or Align Right button on your remote control.

    Without manual steering:

    You drive the truck at walking pace, steering left or right in such a way that the axles of the semi-trailer twist into the straight-ahead position.

    You can check whether the marks on the steering wing or on the axle assembly are exactly in line with each other.

    When the axles of the trailer are exactly centred, stop and open the 4 taps in the control box.

    Now drive the truck exactly straight in front of the trailer, now the axles of the trailer will remain in the straight-ahead position.

    When the truck is directly in front of the trailer, put the 4 cranes in the control box back into driving position.

    The combination is now aligned.

  • The electric/hydraulic steering system is protected by several fuses.

    These can be found in the following places;

  • The hydraulic cylinders of the hydraulic steering system are fitted with bleed connections. Where necessary, these are fitted with extension hoses with the quick connectors fitted in easily accessible places. Stickers with the colour of the circuit indicate…

    1.5 How should I bleed the hydraulic steering system?

  • You may encounter the following situations:
    1. The red control lamp is off: (all functions both hydraulic and electrical are OK, or the 24volt voltage from the Battery/Nato cable is not present, or the lights are not switched on)
    2. The red control lamp is flashing: (speed signal not present on the ASA PCB connection Nr23 blue/black)
    3. The red control lamp lights up continuously: in 1 or more hydraulic control circuits (red/blue/green/yellow, too little pre-pressure is present.
    4. The red control lamp blinks and lights alternately for 15 sec : the speed signal is not present and in one or more hydraulic control circuits (red/blue/green/yellow, too little pre-pressure is present.

    The red light may illuminate for several seconds when you steer the truck left or right (e.g. when taking a turn).

    After taking the turn, the lamp should go out automatically when the truck has reached the straight-ahead position, you do not need to do anything in this case.

    If the lamp stays on, there is too little pre-pressure in the hydraulic steering system.

    If your vehicle is equipped with manual steering, you should operate it briefly counterclockwise and clockwise then return it to the automatic centre position.

    Now the red lamp will be off and there is again sufficient pre-steering pressure in the steering system.

    Whether your trailer is equipped with an emergency system depends on the year of manufacture and the version of the ASA control board, if this ASA board (grey junction box in the image below) is equipped with a white push button, your trailer is equipped with an emergency system, in all other cases it will have to be checked on site what caused the malfunction.

    The emergency system works as follows:

    You press the white push button, with this you activate the pump, at the same time you move the steering slider (mounted on the aluminium manifold) via the black ball buttons all the way down or up or from left to right(depending on the position of this steering slider) with this you activate the emergency system and you can move the axles.

    Caution:

    The brakes must be released and when loaded drive slowly forwards or backwards to minimise friction/resistance between the tyres and the road surface.

    Should this not work please contact the Afd. Aftersales or service workshop Wijchen or Zwijndrecht for an appointment, or to call in a service technician.

Factory standards for the MOT inspection

    1. For the EURO, IC, OVBT and OVBQ and MANOOVR, this is measured 570 mm (dimension A) from the centre of the knee bearing.
    2. The shuttle bus must be horizontal.
    3. Measurement is done with the tyres on the ground and on the brake, passing through any play that may be present by hand steering. This may not exceed 5 mm in either direction.
    4. The measurement may also be done by fixing a ruler to the cover of the knee bearing. The ruler/measuring point should be (in the side view) in the centre of the knee bearing. Make sure that the distance A is correct as in the figure below.
