The oil should be changed after the first 100 operating hours and then at
least every 2000 - 3000 operating hours or after one year. At high intake
pressures and intake temperatures and/or when pumping contaminated
gases, the oil will have to be changed much more frequently.
Further oil changes should be made before and after long-term storage of
the pump.
Contact us for more information in this matter.
Required tool: Allen key 8 mm.
Remove the oil-drain plug (6/4) and let the used oil drain into a suitable con-
tainer. When the flow of oil slows down, screw the oil-drain plug back in,
briefly switch on the pump (max. 10 s) and then switch it off again. Remove
the oil-drain plug once more and drain out the remaining oil.
Screw the oil-drain plug back in (check the gasket and reinstall a new one if
necessary).
Remove the oil-fill plug (6/1) and fill in with fresh oil.
Screw the oil-fill plug (6/1) back in.
The tightening torque for the bolts (6/1) and (6/4) has been specified at
10Nm.
We can only guarantee that the pump operates as specified by the
technical data if the lubricants recommended by us are used.
