Otto Bock C-Leg 3C98-3 Instructions For Use Manual page 20

CAUTION
Using the prosthesis in the delivery state (factory settings)
Falling due to unexpected behaviour of the prosthesis because the knee joint locks in the flexion
direction
After receiving the knee joint, it needs to be adjusted with the C-Soft Plus adjustment soft­
►
ware, version 1.10 or higher.
Using the knee joint on the patient without prior adjustment with the adjustment software is
►
not permitted.
CAUTION
Use of the prosthesis with incorrect setting data
Falling due to unexpected prosthesis behaviour caused by triggering the swing phase at the
wrong time.
The prosthesis settings (parameters) have to be checked using the corresponding adjust­
►
ment software and changed as needed.
CAUTION
Improper assembly of the screw connections
Falling due to breakage or loosening of the screw connections.
Clean the threads before every installation.
►
Apply the specified tightening torque values for installation (see the section "Technical
►
data").
Observe the instructions for securing the screw connections and the use of the correct
►
length.
CAUTION
Incorrectly secured screws
Falling due to breakage of load-bearing components caused by screw connections coming
loose.
After completing all settings, the set screws in the tube adapter must be secured before they
►
are tightened to the specified torque (see the section "Technical data" Technical data).
The tube clamp screws must not be secured but only tightened to the specified torque.
►
CAUTION
Incorrect alignment or assembly
Falling due to damage to the prosthesis components.
Observe the alignment and assembly instructions.
►
CAUTION
Errors during prosthesis alignment
> Falling due to unexpected product behaviour as the result of a malfunction.
> Falling due to breakage of load-bearing components.
At maximum flexion, it is essential to maintain a minimum distance of 3 mm (1/8") between
►
the hydraulic unit and the socket.
At maximum extension (reached under full load), it is essential to maintain a minimum dis­
►
tance of 5 mm (1/4") between the sealing sleeve/top edge of the installed Protective Cover
