Checking the hydraulic pressure filter
In order to ensure long, error-free operation, we recommend you use a hydraulic
pressure filter (
). If the hydraulic pressure filter becomes contaminat-
ed, you will need to replace the filter cartridge with a new filter cartridge.
To detect contaimination, the pressure filter (
) has a contamination in-
dicator (
position 1).
We therefore recommend you reset the contamination indicator manually when
the operating temperature of the hydraulic oil is reached.

Replacing filter cartridges
Ensure that the hydraulic system is
depressurised
and
has cooled down
.
Place catch pan underneath the pressure filter to collect escaping hydraulic
oil.
Wear protective gloves and goggles.
1.
Undo the filter top (
position 3) with a SW24 spanner
2.
Unscrew the filter top from the hydraulic pressure filter.
3.
Replace the contaminated filter cartridge with a new filter cartridge.
4.
Clean the filter top and filter head (
position 2) in the region of th
ethread and the sealing surface and examine for mechanical damage.
5.
Check the O-rings and replace where necessary.
6.
Screw the filter top (
position 3) with the SW24 spanner as far as
the stop and undo the filter top one quarter of a revolution.
NOTICE
With cold oil and pressure peaks, the contamination display/display pin may trig-
ger even though the filter is not contaminated.
