Cleaning, maintenance and repair
12.11.7 Clean / exchange the filter in the hydraulic plug
Not with Profi-folding.
The hydraulic plugs are equipped with a filter
(Fig. 172/1) that may block and then have to be
cleaned / exchanged.
This is the case when the hydraulic functions run
slower.
1. Unscrew the hydraulic plug from the filter
housing.
2. Remove the filter with compression spring.
3. Clean / exchange the filter.
4. Re-fit the filter and compression spring cor-
rectly.
5. Screw back on the hydraulic plug. In doing
so, observe the correct seating of the O-ring
seal.
