8.1.4 Connecting the hydraulics Attention! Dirty hydraulic couplings can lead to contamination of the hydraulic system.

– Clean the hydraulic couplings and the hydraulic hoses every time before hitching. – Prevent the control cable from scuffing or being squashed. 7 Caution! Before connecting the hydraulic hoses, make sure that the swather's hydraulic system has been adapted to that of the tractor. – See Adapting the hydraulics, page 26. – Do not exceed the max. permitted oil quantity – see Specifications, page 20. – The machine's pressure relief valve must be set to a higher value (+20 bar) than the tractor's relief valve.

The return line (without marking) must never be put under pressure, as this could damage the swather's hydraulic system.

– Connect the return line (without marking) only to the “pressure-free return” coupling. Proceed as follows to connect the hydraulics:
• Connect both hydraulic hoses (1) to a dual-acting control valve (Fig. 7) or
• to a single-acting control valve with “pressure-free return” (2) (Fig. 8).
• Protect the hoses from scuffing or being squashed.
• Adjust the tractor's hydraulic system for the max. permissible oil flow – see Specifications, page 20. See the tractor's operating manual, e.g. under “Continuous operation of hydraulic motors”. (Fig. 7, 8)
