4.6 To depressurise tank, open the ball-shut-off valve and let air suck. Then take pump (P) out of
tank and dispose liquid properly .
5 . Maintenance and Cleaning
5.1 The tank is not determined to store the liquids. After every use tank has to be emptied. In case
other liquids than oil are used, tank has to be cleaned (with water or an appropriate cleaning
agent.) after every usage. Disposal of the liquid and the liquid to be used to flash the tank has
to be determined in conjunction with the information given by the manufacturer of the liquid
which has been sucked. Please, make sure that also the liquid with which the unit is flashed
will not do any harm to the components of the equipment.
5.2 The life of the unit can be extended if the piston (M) is greased occasionally.
5.3 To disassemble the pump with the piston (M), pull the pump handle all the way out, make sure
that the guiding lever (F) is clicked into position and turn handle counterclockwise 1/8 of a turn.

* Piston (M) is broken
* Suction (SV) is damaged
* Obstacle enables valve to be closed
6.3 Pump cylinder is pulled due to under-pressurisation
* Suction valve (SV) is glued

filling funnel
* Tank is full
* Tank is not upright
* Pump sleeve (U) is missing
* Pump sleeve (U) is broken
