    Pronar T683 SECTION 2 • Before hitching trailer to tractor 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 hitching up machines should stand outside the area of danger and be visible to the tractor driver at all times.

  • Page 29: Loading And Unloading

    SECTION 2 Pronar T683 • 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.
