Filtering of an operating fluid of a mechanical device is performed
utilizing a pumping device of the mechanical device which routinely
circulated the operating fluid within the mechanical device. A remote
filtering station of the present invention has a first conduit to contain
the operating fluid during transfer from the mechanical device, a filter
and a second conduit to contain the operating fluid during transfer back
to the mechanical device. In the most preferred embodiment a filter
replacement adapter is attached in place of the mechanical device's
filter during the filtering procedure. The mechanical device is operated
during the filtering procedure where the pumping device of the mechanical
device circulates the operating fluid through the mechanical device and
through the filter of the remote filtering station. This provides for a
cleansing of all of the conduits of the mechanical device which routinely
has the operating fluid circulated therethrough.
