If the thruster needs to be disassembled for purpose of maintenance work, preparations
have to be made for retaining the weight of up to 40 kg.
The maintenance of thrusters is limited to a regular function and oil inspection. With normal
operating conditions it should be performed every six months. The intervals of oil change depend on
the conditions of application. If the oil shows significant modifications in viscosity or has become
significantly darker, it must be changed as follows:
•
The dismounted thruster must be positioned horizontally with the oil filling hole at the bottom..
•
After opening of the oil filling screw (component 9) the oil must drain.
•
For a complete discharge the unit has to be held with the piston rod pointing vertically to the
bottom.
•
Hold the unit with the piston rod pointing upwards and wait until the remaining oil has run out
of the cylinder, afterwards hold the unit pointing upwards. Repeat this process several times.
•
Afterwards wash the housing with some clean oil.
•
With the unit being in vertical position oil must be filled in either to the overflow screw or the
filling limit of the filling screw, each depending on the type. The hydraulic oil HL 10 DIN 51524
should be used here.
•
Now some lifting motions should be made to fill the air chambers. The oil level should be
corrected, if necessary.
•
The oil filling screw (component 9) must be retightened.
•
The thruster can be mounted and put into operation.
