The oil quantities given in table 2 are average quantities. They will decrease in case of thruster types
with valves and/or springs.
Ed-thrusters are filled with hydraulic oil, grade HL 10 DIN 51524 for temperature range from -20°C to
+50°C. For different temperature ranges special oils are required.
This "long-life" filling is not subjected to any wear or dirt during operation as long as the unit is in
perfect condition.
With refilling after repair any other brands than used for initial filling of category HL 10 DIN 51524
can be used. All bearing positions in the Ed thruster have an initial grease lubrication which means
that Ed thrusters are mainly maintenance-free.
Exceptions:
Thrusters as a firedamp-proof type are filled with flame retardant hydraulic liquid according to the
provisions of the German Mining Authority.

STOP
Excess pressure is generated in the cylinder space of thrusters with operating temperature.
That is why there is the danger of burning with hot operating liquid when opening the filling
screws! Danger of burning!
Operating liquid (hydraulic oil) may only be inspected, refilled or drained in a deactivated
and cold state!
The thruster is filled functionally if the level of the operating liquid in vertical position with the lifting
rod retracted comes up to the lower edge within the filling hole.
The thrusters Ed 300/50, Ed 500/60 and Ed 800/60 must be filled to the overflow screw.
With too low filling the unit does not generate the full lifting force. With excessive filling an
impermissibly high internal pressure is generated in the unit.
