11. Adjust the oil level in the application to the required level and assure that this
corresponds to a level between the two lines marked on the lower reservoir.
If necessary, adjust the height of the lower reservoir by means of the support
bracket screw.
12. Screw the upper reservoir tightly onto the lower reservoir ensuring that the
extended neck is flush with the oil level in the lower reservoir. Use the six
rubber gaskets to obtain the correct height. (Ensure the gasket with the
smallest bore remains on top).
13. For high precision applications use the support bracket screw for the fine
tuning (otherwise the accuracy will depend on the thickness of the gaskets).
14. Unscrew the cover of the upper reservoir and fill it with the same oil as used
in the application.
15. Screw back the cover tightly, ensuring that no air can enter into the upper
reservoir. This will also open the valve at the bottom of the upper reservoir
and hence connect the upper and lower reservoir to each other.
16. Start the machine. As the oil in the application will lower due to splashing, oil
will flow from the lower reservoir into the application, exposing the extended
neck to open air. This will allow air to enter the upper reservoir and hence oil
to flow down to the lower reservoir.
Once the oil has reached the preset level, air can no longer pass to the upper
reservoir, effectively stopping the flow of oil.
N.B.: During stand-still the oil will stop splashing and the level in the application
will rise. As a consequence the oil level in the oil leveller will also rise above the
preset level.
