Environmental protection
Always take care when collecting the old hydraulic fluid. Guard
against spillages. Separate the collected hydraulic fluid and the
used filter inserts from other waste.
Dispose of all components in accordance with current applicable
regulations!
Comply with the relevant national and regional regulations.
Only work with waste disposal companies who are approved by
the responsible authorities.
Use a tool to unscrew the retaining bracket (3).
Unscrew the filter casing (2) by hand. Drain the hydraulic fluid
from the filter casing into the pan.
Remove the filter insert.
Dispose of the old filter insert and the drained hydraulic fluid in
accordance with local specifications.
Caution
You must never attempt to clean filter inserts. You must always re-
place them.
The filtering process causes dirt particles to accumulate in the filter
casing. You must therefore clean the filter casing thoroughly before
refitting the new filter insert, otherwise the new filter insert will rapidly
become clogged again.
Clean the filter casing thoroughly using a clean rag.
Caution
Before you fit the new filters, you must check all O-rings and other
seals on the filter inserts and replace them if damaged.
Check all O-rings and other sealing elements. Replace them if
damaged.
Check that the order number on the new filter insert matches
the order number on the filter plate.
