5.2 – Motor Case Oil Filling
All motors are supplied without lubricating oil. Before start up, the motor case must be
filled in by using the same hydraulic oil used to operate the motor.
The two case drain holes are both plugged one with a metal plug and the other one with a plastic plug.
To fill in the motor case it is necessary:
to place the motor in its working position, making sure to close the lower case drain hole by means
of the metal plug;
use the upper case drain hole to fill in the motor case, by using the same hydraulic oil used in the
system, up to the level required to ensure the perfect lubrication of the bearings.
Oil must be pre-filtered (pls. refer to the “Operating Fluids” section).
In the table below pls. find the volume of oil necessary to fill in the case according to the motor size:
