9.12.4 Checking hydraulic pressure filters
To ensure long and fault-free operation, we recommend application of a hydraulic
pressure filter (
figure 9.20 ). If the hydraulic pressure filter is soiled, replace the fil-
ter cartridge.
The pressure filter is equipped with an indicator of soiling.

Replacing filter cartridges

Ensure that the hydraulic system is depressurised and cooled-down .

Position a collecting vessel for leaking hydraulic oil under the pressure filter.

Put on protective gloves and protective goggles.
1. Loosen the filter housing [3] with a SW24 spanner.
2. Untighten the filter housing from the hydraulic pressure filter.
3. Replace the soiled filter cartridge by a new one.
4. Clean the filter housing [3] and filter head [2] around the threading and the
sealing surface and check for mechanical damage.
NOTICE
If the oil is cold or in case of pressure peaks, the indicator pin may trigger al-
though the filter does not yet need to be replaced.

Push the indicator pin inside after the operating temperature is reached.

If the indicator pin triggers again, the pressure filter needs to be replaced.
