Cleaning intake sieves
The intake sieves inside of the hydraulic fluid tank must be checked for soiling every
two years before filling up the fresh hydraulic fluid by optical inspection. If the sieves
are soiled, they must be cleaned.
– For this purpose, the metal lid of the hydraulic fluid container must be taken off.
– Flush the intake sieves from inside to the outside using sufficient cleaning agent.
– Reinstall the intake sieves.
– Place the gasket and the metal lid onto them.
– Before installing them, coat the bolts for fastening the metal lid with sealing com-
pound (ROPA item no. 017026) and tighten the bolts.
– Before filling up with fresh hydraulic fluid, replace all filters in the hydraulic sys-
tem. These filters are non-reusable products. They may not be cleaned. Cleaning
destroys the filters. The hydraulic system might sustain heavy damage.
– Fill up the hydraulic system only using approved hydraulic fluid.
