• Do NOT unhitch the trailer from the tractor when the tailgate and the sliding wall
are raised. Exercise caution when disconnecting trailer.

2.1.3 HYDRAULIC AND PNEUMATIC SYSTEMS

• When operating, the hydraulic and pneumatic systems are under high pressure.
• Use the hydraulic oil recommended by the Manufacturer. Never mix two types of
oil.
• Regularly check the technical condition of the connections and the hydraulic and
pneumatic conduits. There must be no oil or air leaks.
• Periodically drain water from the air tanks in pneumatic system. During frosts,
freezing water may cause damage to pneumatic system components.
• 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).
• After changing the hydraulic oil, the used oil should be properly disposed of. Used
oil or oil which has lost its properties should be stored in original containers or
replacement containers resistant to action of hydrocarbons. Replacement
containers must be clearly marked and appropriately stored.
• Do not store hydraulic oil in packaging designed for storing food or foodstuffs.
• Rubber hydraulic conduits must be replaced every 4 years regardless of their
technical condition.
