6.4 Hydraulic installation maintenance.
Always follow the principle that the oil in the spreader hydraulic system
and the oil in the external hydraulic system of the tractor are to be of the
same type. The use of different types of oil is not permitted.
The hydraulic system of the spreader should be completely tight.
Checking the tightness of the hydraulic system consists of connecting the
spreader to the tractor, running the hydraulic cylinder and storing it in the
position of the maximum extension of the cylinder with the loading crate
tilted for 30 seconds.
In the case of noticing oil leaks on connections of hydraulic conduits, you
must tighten the connector, if this does not rectify the fault, replace the
conduit or the connector with a new one. If the oil leak occurs beyond the
connection, the leaking conduit system should be replaced. Exchange of a
component to a new one is also required for any damage of mechanical
nature.
Hydraulic hoses should be replaced at least every four to six years from
their date of manufacture, unless previously found to be damaged and
