7 Maintenance and Care
Before filling with fresh hydraulic fluid, replace both filters of the hydraulic system. These
filters are disposable products. They may not be cleaned. Cleaning destroys the filters
and the hydraulic system may sustain severe damage.
An intake return filter (5) is located on the hydraulic fluid tank. When replacing the filter
element – as during all work on the hydraulic system – observe absolute cleanliness.
Ensure that the O-ring seals in the filter housing are neither damaged nor soiled. Before
opening the filter housing, ensure that the hydraulic system is fully depressurized and
that the fluid filling cover is open.
