Sampling

Fig. 1

Fix one instruction sticker (Fig. 1): • In the cab. • On the hydraulic fluid tank • On the equipment. • Put the machine into operation. Check level in hydraulic tank according to servicing plan. • The hydraulic fluid may dissolve deposits in the hydraulic system. - Therefore change all filters 30 to 50 operating hours after making the change. - Make further filter changes according to the servicing plan. • Sample the hydraulic fluid after 30 to 50 operating hours and send in for analysis (see section

“Environmentally compatible hydraulic fluid, sampling”).

Sampling

Special analysis sets are compiled for taking samples. They contain all necessary parts. • Analysis sets are available from our spare-parts service. • After 30 to 50 operating hours with environmentally friendly hydraulic fluid, take the first sample. - Send this sample in for analysis. • After this, we recommend sending in a sample for analysis every 1,000 operating hours or once a year. • It is essential that the hydraulic fluid should be analyzed not later than after 3,000 operating hours. - The results of the analysis show whether the hydraulic fluid is still serviceable and the changing intervals can be extended. - In case of questions ask our service department.
