6.6 Adjusting the Humeral Rotation Feature

6.7 Installing the Pull Cable

CAUTION
Removing the pull cable
Injury due to malfunction of the product.
► The pull cable on the 12K501 AxonArm Ergo is to be used for emergency operation only. For safety reasons, it
must not be removed. When the Axon-Bus prosthethic system is switched off or defective and when the bat­
tery is empty, the AxonArm cannot be locked or unlocked without the pull cable.

6.8 Checking the Symmetry

1) Connect the Axon-Bus gripping component (e.g. Michelangelo Hand) to the AxonArm.
2) Check the symmetry with respect to the other hand (e.g. using the 743L20=230 Ottobock Laser-Line).

3) Secure the strap (e.g. using an artery clamp).
INFORMATION: When using an artery clamp,
verify that the jaws of the artery clamp have no
sharp edges. Otherwise, tape over the jaws to
protect the strap.
4) Loosen the screw on the strap clamp, but do not
remove the strap clamp.
5) Shorten or lengthen the strap.
Lengthening the strap: preflexion is decreased.
Shortening the strap: preflexion is increased.
6) Tighten the screw on the strap clamp.
7) Remove the strap securing device (artery clamp).
A 3 mm change in the strap length results in an approx.
5° change in the flexion angle (preflexion).
The free swing range is changed by the same amount
as the flexion angle. The start of the adjacent compens­
ation region changes accordingly.
The factory-set preflexion is approx. 10°.
► The humeral rotation turntable has integral stops
(+/- 80 degrees) to block extreme movements.
Turntable friction is easily adjusted by turning of the
external adjustment screw, using a coin or similar
object.
1) Bring the forearm into neutral position (no outward
or inward rotation).
2) Affix the cable guide to the socket with cap screws
(centred in relation to the strap clamp and approx.
30 mm away from the lamination ring).
3) Test inward and outward rotation of the socket up to
the stop. Ensure that the pull cable cannot be ten­
sioned (loop).
