hydraulic cylinder 752 "Baling pressure reached" pressure relief valve (260 + 10 bar) 760 One-way restrictor, one-sided 801 Quick release coupling (tractor port) 912 Baling pressure gauge Z8 Wrapping start oil pressure switch (Baling pressure 220 bar reached) Description of function: 1/2 Closing the tailgate The oil is pumped from port A of quick release coupling 801 via the pilot- controlled non-return valve 734 to the tailgate cylinders 318. During this process, the rising oil pressure unblocks the lock-up valve units 734-1 and 734-2. The oil displaced by the cylinders flows back into the tank via port B of quick release coupling 801.

The baling pressure gauge 912 displays the tailgate closing pressure. 03/04 Ro-160 2-3
