7 Maintenance
► A visual inspection and functional test of the prosthetic components
should be performed after the first 30 days of use.
► Inspect the entire prosthesis for wear during normal consultations.
► Inspect the product for visible damage every six months. Make additional
inspection appointments as needed (e.g. for highly active or heavy
users).
► Check the condition of the functional ring as part of each inspection. If
the user frequently compresses the functional ring to the stop while
walking, or if the functional ring exhibits visible damage, replace the
functional ring (see page 24).

base body. The O-rings on the adapter and the mounting screw are also
replaced together with the functional ring.
