Back buffers (with holes)
Navy X-Soft
Yellow Soft
Red medium
Brown Hard
Blue X-hard
Front buffers (without hole)
Brown Standard
Blue X-hard
The hardness of the buffers must be selected and inserted to suit the patient's requirements.
Note: if the user feels unsafe while walking, e.g. has a gentle wobble during the stance phase, use the next hardest
buffer.
If the user feels that there is too little damping in the stance phase, use the next softest buffer.
Mounting the buffer elements
The buffer without a hole is the front stop buffer (A).
The back buffer (P) with holes for progressive damping, is mounted in the IKF adapter with the holes facing
upwards (Fig. 2).
Balance Knee KFM1 with loop adapter
• Fill the central thread of the loop adapter (39) completely with Plastelin, so that no resin can run into the thread
during lamination and the central screw can later be completely screwed in. Safety relevant!
• Make up a dummy disc and fix this to the adapter with double-sided adhesive tape.
• Laminate the loop adapter (39) with sufficient carbon fibre and fibre glass to suit the patient's needs.
Important:
Please make sure it binds well in the groove!
• After lamination, grind the distal end of the adapter free and remove the Plastelin.
• Slide the washers (34 & 35) over the 29 mm central screw (32) and guide the screw through the central opening
in the head of the joint (26).
• Slide the adjustment discs (38) over the thread of the central screw (32) and tighten the loop adapter (39) to a
torque of 35 Nm.
• When mounting the two adjustment discs, make sure that their fine teeth are facing each other on the inner
surfaces.
• Secure the 29 mm central screw (32) with Loctite and use a torque wrench (8mm Allen key).
Balance Knee KFM1 with 3-arm socket adapter
• Before adjusting (moulding) the 3-arm socket adapter to the individual socket form, screw the adapter with an
external thread (37) into the internal thread of the 3-arm socket adapter. Secure the M5 locking screw of the
3-arm socket adapter to a torque of 10 Nm.
• Mould the 3-arm socket adapter to the individual socket shape.
• Loosen the M5 locking screw on the 3-arm socket adapter and remove the attached adapter.
• Cover the internal thread of the 3-arm socket adapter with grease and screw in the dummy supplied. Secure the
M5 locking screw of the 3-arm socket adapter again to a torque of 10 Nm. Fill the slit in the 3-arm socket
adapter, the screw head, and any exposed thread with Plastelin.
• Laminate the 3-arm socket adapter with sufficient carbon fibre and fibre glass to suit the patient's needs.
• After lamination, loosen the M5 locking screw of the 3-arm socket adapter and remove the screwed-in dummy
and any remaining resin or Plastelin.
• For the final assembly, now completely screw the adapter with an external thread into the internal thread of the
3-arm socket adapter.
