11.4 Care
The hydraulic uid should be changed if dirty at least once a year. When the hand pump is
operated in an especially dusty environment, we recommend changing the uid at least once
every half year.
ATTENTION!
Add hydraulic uid only if the hand pump is disconnected from the lines or the
equipment operated with the pump is hydraulically depressurised. Otherwise,
after lling the entire hydraulic system could contain more hydraulic uid than
the tank can hold.
Procedure:
1. Open the bleed/ll cap on the tank.
2. Add hydraulic uid until the uid level comes up to 1-2 cm below the top edge of the oil
tank.
3. Bleed the hand pump as described in the chapter "bleeding the pump".
4. Check the uid level again and close the tank again at the correct uid level with the
vent/ll cap on the tank. Should the tank no longer be sufciently full after bleeding, start
the ll procedure again at item 2.
NOTE:
Should the uid level in the tank still not be reached after repeated relling (during
maintenance), we recommend searching for leaks in the hydraulic system.
If possible, do not store the hand pump in a damp or extremely dusty environment in order
to ensure a long service life. If this is unavoidable, you should perform more frequent
maintenance and/or shield the pump from these effects if possible.
Regularly coat all metal parts with oil to prevent any corrosion.
