• Before hitching the trailer check that both machines are in good technical
condition.
• Be especially careful when hitching the machine.
• When hitching, there must be nobody between the trailers. Person assisting in
hitching the machines should stand outside the area of danger and be visible to
the tractor driver at all times.
• Do NOT proceed with unhitching the second trailer from the tractor when load box

2.1.4 HYDRAULIC AND PNEUMATIC SYSTEMS

• When operating, the hydraulic and pneumatic systems are under high pressure.
• Regularly check the technical condition of the connections and the hydraulic and
pneumatic conduits. There must be no oil or air leaks.
• Cut-off valve in the hydraulic tipping system limits the tipping angle of the load
box when tipped to the sides and to the rear. The length of the control cable
controlling this valve is factory adjusted by the Manufacturer and must not be
changed when the trailer is used.
• In the event of malfunction of the hydraulic or pneumatic system, do not use the
trailer until the malfunction is corrected.
• When connecting the hydraulic conduits to the tractor, make sure that the
hydraulic system of the tractor and the hydraulic system of the trailer are not
under pressure. If necessary, reduce residual pressure in the system.
• In the event of injuries being caused by pressurised hydraulic oil, contact a doctor
immediately. Hydraulic oil may penetrate the skin and cause infections. In the
event of contact of oil with eyes, rinse eyes with a large quantity of water and in
the event of the occurrence of irritation consult a doctor. In the event of contact of
oil with skin wash the area of contact with water and soap. Do NOT apply organic
solvents (petrol, kerosene).
• Use the hydraulic oil recommended by the Manufacturer.
