Pronar N262 N262/1 SECTION 5 If the manure spreader is unhitched from the tractor, contact should be protected by cover or placed in its designated socket. Before the winter period it is recommended to preserve the seal with special preparations (e.g. silicon grease for rubber elements).
Page 117: Hydraulic System Operation
SECTION 5 Pronar N262 N262/1 Reduction of pressure is achieved by tilting the drain valve mandrel. Remove the pneumatic line by loosening the nut (2). Fit the new line. The interior of the line should be clean. The ends of the pneumatic line (1) must be cut exactly at right angles.
