Checking the operating fluid

WARNING
Hot operating fluid
Risk of burns due to hot oil plumes when opening the filling screw
when at operational heat.
– The operating fluid may only be checked, topped up or
drained when switched off and cool.
®
– The ELDRO
temperature of 40 °C.
NOTE
If not filled sufficiently, the thruster does not develop the full lifting
force.
If overfilled, the thruster's internal pressure is impermissibly high.
The ELDRO ® thrusters are filled correctly if the operating fluid level
reaches the lower edge within the filling opening when the thruster is
upright and the lifting rod is retracted.
Observe the disassembly instructions if the ELDRO
not installed upright (⇒ Disassembly chapter).
 Place the ELDRO
 Remove the filling screw from the filling nozzle.
 Check the fill level according to the ELDRO
required.
