5. Maintenance .
5.1 Wear parts .
Sealing in the test connections is purely metallic using a sealing cone. The individual components are
made of wear-proof materials. Should the seal faces show signs of wear or damage on the interior or
exterior cone, the components must be replaced. In this case, please contact the manufacturer.
5.2 Changing the hydraulic oil
.
The hydraulic oil should be changed whenever visible contamination is present.
5.2.1 Removing hydraulic oil .
Open the locking screw with the oil filling symbol on top of the basement
Siphon the oil out of the tank, for example, by using a suitable nozzle
Small amounts of oil residue additionally may be siphoned off the test connections opened. For
this purpose, the spindle pump must be slowly turned in clockwise with the low-pressure and high-
pressure shut-off valves open.
Minute amounts of oil residue may remain in the piping
In case of severe contamination of the hydraulic oil, the complete cleaning of the
piping and of all media-contacted individual components of the basement in a
dismantled state may be advisable. This procedure may be performed by the
manufacturer only.
Waste oil must be disposed of according to legal requirements.
