Changing the operating fluid

66 / 75
WARNING
Hot operating fluid
Risk of burns due to hot oil plumes upon opening the filling screw
when at operational temperature.
– The operating fluid may only be checked, topped up or
drained when switched off and cool.
– The EdEx thruster may only opened at a maximum
temperature of 40 °C.
NOTICE
If not filled sufficiently, the thruster does not develop the full lifting
force.
If overfilled, the thruster's internal pressure is impermissibly high.
 Position the EdEx thruster vertically above a suitable collecting
container
 Remove filler and drain plug.
 After the thruster has been completely emptied, close the drainage
opening firmly again
 New operating fluid (⇒ data on type plate)
The explosion-proof EdEx thruster is filled correctly if the fluid
level reaches the lower edge within the filling opening when the
thruster is upright and the lifting rod is retracted.
 Perform several lifting movements to avoid possible air pockets
 Then check the fill level again and top up operating fluid if
necessary
 Tightly close the filler plug when the required fill level is reached
 Dispose of used liquid (⇒ Disposal chapter).
