Light materials with a large volume, maybe loaded even above the edge of the load box extension walls paying special attention to trailer stability. Regardless of the type of load carried, the user is obliged to secure it in such a manner that the load is unable to spread and cause contamination of the road.

  • Page 54: Transporting Loads

    4.5 TRANSPORTING LOADS When travelling on public or private roads, respect the road traffic regulations, exercise caution and prudence. Listed below are the key guidelines for driving the tractor and trailer combination. • Before moving off make sure that there are no bystanders, especially children, near the trailer or the tractor.

  • Page 55: Unloading

    importance because loaded trailer's centre of gravity is higher, which reduces safety. Driving near ditches or channels is dangerous as there is a risk of the wheels sliding down the slope or the slope collapsing. • Speed must be sufficiently reduced before making a turn or driving on an uneven road or a slope.
  • Page 56 • after unloading a lot where there is an old box, clean the residual material from the load box edge, the walls and wall extensions, • close and secure the walls and wall extensions or chute opening, • before moving off make sure that tipping pin are in correct position, i.e. with the handle facing downward and secured with cotter pin - see figure (4.2A).
  • Page 57 Rear load box wall is equipped with chute slide gate (1) and chute opening (2) (additional accessory) – figure (4.3A) which is used for unloading of loose materials. Chute design allows very accurate dosing of the material to packaging (sacks, boxes etc). The opening gap can be controlled using a lever (4).

  • Page 58: Disconnecting From Tractor

    DANGER Tipping the load box must be done on hard and level ground. Use only original pins with a handle and securing cotter pin. Using third-party pins could damage the trailer. Tipping pins must be correctly interlocked. When opening load box sidle wall locks take particular care, because of the pressure of the load on the wall.
  • Page 59 checks should be made after the first use, after the first journey with a load and then every 6 months. The above actions should be repeated individually if a wheel has been removed from the wheel axle. • Regularly check and maintain correct pressure in tyres according to instructions (especially if trailer is not used for a longer period).

    The parking brake system should be inspected annually and in case of need should be regulated. 5.4 PNEUMATIC SYSTEM OPERATION As a part of trailer maintenance, it is necessary to conduct inspection of individual pneumatic systems, giving particular attention to places of all connections. Tightness of the system should be checked at nominal pressure in system of approximately 600 kPa (6.0 kg/cm If conduits, seals or other system elements are damaged, compressed air will escape in these damaged places with a characteristic hiss.
  • Page 67 body should be carefully washed out and blown through with compressed air. Assembly should be done in reverse order.

Contact of the seals with fuel, lubricants being petroleum derivatives, paints etc., causes rapid ageing of the material from which they are made. Connection should be inspected every time before connecting trailer to tractor.
  • Page 69 sub assemblies is equally required in each instance of mechanical damage. In the event of confirmation of damage of hydraulic ram cylinders they must be replaced or repaired. In such an event the whole set of seals must be changed. Hydraulic conduits should be replaced after 4 years of trailer use.
