5) Depending on the size of the chosen Protector foot cuff, mark the following distances in at
least three places on the Protective Cover (Abmessen):
INFORMATION: The distances have to be measured from the foot contact surface
each time, creating a cut edge parallel to the foot contact surface. This allows the Pro­
tector foot cuff to overlap over the Protective Cover main component to an ideal
extent.
• Size S: 110 mm
• Size M: 120 mm
• Size L: 125 mm
6) Remove the Protective Cover.
7) Fasten the upper closure (see fig. 14) and lengthwise closure (see fig. 7).
8) Tape off the Protective Cover with crepe adhesive tape above the mark.
9) Using a vibrating or band saw, shorten the Protective Cover along the bottom edge of the
crepe adhesive tape (see Fig. 8).
INFORMATION: Make sure that the closures are not shifted while sawing.
10) Deburr the cut edge.
NOTICE
Loss of stability due to shortening the Protective Cover too much
Protective Cover does not stay in place on the knee joint.
At the most, the Protective Cover may be shortened to just before the marked rib (see fig. 3).

► Using suitable tools, remove the profile ribs on the interior of the Protective Cover (see
