  • Page 24: Environmental Hazards

    Pronar T700M SECTION 1 1.6 ENVIRONMENTAL HAZARDS A hydraulic oil leak constitutes a direct threat to the natural environment owing to its limited biodegradability. The negligible solubility of hydraulic oil in water does not cause extreme toxicity of organisms living in the aquatic environment. The formation of a film of oil on the water may be the direct cause of physical action on organism, perhaps causing change of oxygen values in the water because of lack of direct contact of air with the water.

Profiled rubber seals, silicone sealers, plastic wrap, rope or textile materials are recommended materials to provide sealing of the load box. Additionally, it is recommended to protect the load with tarpaulin cover. It protects the load against spilling during travel, being blown away by the wind and also protects load against moisture.
  • Page 87 SECTION 4 Pronar T700M High volume loads High-volume loads such as hay, straw bales (rectangular or round), green fodder, etc., are recommended to be loaded with the aid of appropriate implements: grabs for rectangular or round bales, etc. The load must not be higher than the load box wall extensions. Otherwise, the trailer will exceed the maximum height of 4m allowed for vehicles on public roads.

  • Page 88: Transporting Load

    Pronar T700M SECTION 4 It is impossible to describe all methods of loading due to the diversity of materials, tools, means of fixing and securing a load. The trailer user must carefully read the regulations concerning road transport and comply with them.
  • Page 89 SECTION 4 Pronar T700M • While driving on public roads the trailer must be fitted with a certified or authorised reflective warning triangle. • Comply with all road traffic regulations and keep all road lights and indicator lights clean at all times and ensure they are in good condition. Any damaged or lost lamps or indicator lights must be immediately repaired or replaced.

  • Page 90: Unloading

    Pronar T700M SECTION 4 4.6 UNLOADING The trailer is equipped with hydraulic tipping system and suitable frame structure and the load box allowing tipping to the rear. Tipping of the load box is controlled from driver's cab using external tractor hydraulic system manifold.
  • Page 91 SECTION 4 Pronar T700M While unloading high-volume materials be especially careful. Do NOT tip load box on uneven or wet ground and move and jerk trailer during unloading. Bulky materials are normally difficult to unload. Therefore, proceed cautiously and patiently. Careless operation of trailer may pose a danger to operators and bystanders can also cause damage to the machine.

  • Page 92: Proper Use And Maintenance Of Tyres
