procedure in the test tank, and then resume oil extraction.
There is no need to empty the test tank during vacuum generation, but this is recommended because of the higher oil extraction
effi ciency of an empty test tank.
Extraction of oil by gravity method
This method does not use the test tank or the compressed air source.
Make sure that the pan underneath it is closed. Make sure that the main tank valve is closed.
Then place the tool so that the pan is under the tank oil outlet. Open the tank oil outlet and allow the oil to drain into the pan. After
emptying the tank, close the oil outlet, open the pan valve and allow the oil to fl ow from the pan into the main tank. After emptying
the pan, close the pan valve.
Emptying the main tank
Caution! Before emptying the main tank, make sure that the valve under the test tank and the pan valve are closed. Oth-
erwise, emptying the main tank may fail and the oil stored in the main tank may escape into the pan and/or control tank.
The main tank has an oil level indicator on the side surface. If the oil reaches the top edge of the indicator, empty the main tank.
Fix the end of the tank emptying hose to the tank into which the oil from the main tank will be transferred.
Adjust the pressure in the compressed air source so that it does not exceed the maximum tank emptying pressure given in the
technical data table.
Make sure the air inlet valve on the container is closed and then connect the compressed air source to the inlet (XII).
Open the valve of the main tank, if the tip of the tank emptying hose is below the oil level in the main tank, the oil will automatically
drain from the main tank on the principle of connected vessels. Open the air inlet valve to the main tank, the compressed air en-
tering the main tank will displace the oil stored in the main tank. After the oil has ceased to fl ow out of the main tank, close the air
inlet valve, disconnect the compressed air source, and then wait until all pressure of the air injected into the main tank has been
discharged, and close the main tank valve.
The main tank shall be equipped with a safety valve which, if the pressure limit for the tank is exceeded, releases excess pressure.
The valve can also be lifted manually (XIII) to equalise the pressure in the main tank.
MAINTENANCE, TRANSPORT AND STORAGE
Clean the external surfaces of the product with a diluted water-based cleaning agent designed to remove engine oil residues.
Do not use fl ammable cleaning agents, solvents, petrol or alcohol. Do not use corrosive or abrasive agents. Clean the pan in the
same manner as the external surfaces.
The interior of the product should be rinsed at least once every six months with water-based cleaning agents, using vacuum and
gravity methods. This will allow the removal of contaminants which have entered the tanks together with the used oil.
Transport the product over short distances, e.g. within the workshop when using the product wheels. In the case of transport
over longer distances, the product should be cleaned, disassembled and transported in the factory packaging. Regardless of
the distance, the product should always be transported disconnected from the compressed air source and with equal pressure
in both tanks.
The product should be stored disconnected from the compressed air source and with equal pressure in both tanks. The tanks and
the pan should be emptied and cleaned for storage. The product can be stored assembled or disassembled. Keep out of reach
of unauthorised persons, especially children. The place of storage should protect against high temperatures, direct sunlight, and
provide good ventilation so that no condensation of water vapour can form on the product.
