3. Retighten screw V1 to 5 Nm
C. Setting
For the patient's safety, the orthopaedic prosthetist must perform the initial test with the factory settings, between
parallel bars.
The foot model used may influence the knee settings. The knee should be set whenever the foot has been
replaced.
After any maintenance operation, the knee will need to be set again.
Setting the extension return:
Use a flat-head screwdriver to tighten or loosen the screw (5), to obtain the requisite return
force.
The screw (5) must never protrude past the bush (7) by more than 2 mm.
Setting the extension stop:
NB: this setting adjusts the knee geometry, and therefore the alignment.
Loosening screw (6) improves the bend security, but the knee will be harder to bend.
Perform this operation using a 3 mm Allen key (2.5 mm for 1M112/1M113), with the patient
loading their prothesis, in order to hold the stop in place in its housing.
Note: Knee 1M05 supplied with two extension stops: one normal which comes pre-fitted, and the other hard which can
replace the normal one.
After setting, check that the knee can be fully bent. If not, loosen the screw slightly.
Friction setting:
Perform this setting only on the two screws situated on the right-hand side of the knee. Any operation on the left-hand side
of the knee could compromise the performance of the joint.
a) Unlock the central screw (3) using a 2 mm Allen key.
b) Tighten or loosen the main screw (4) using a 4 mm Allen key, until you obtain the desired setting.
c) Once you obtain the setting, retighten the central screw (3) using a 2 mm Allen key (tightening torque 2.5Nm)
Setting the lock (Version V):
Use the remote unlocking handle or any other handle with a stroke of at least 12 mm.
Make sure that the knee is extended to perform the settings.
This device is not designed to be unlocked "under load".
a) Mount the sheath and cable, so that it is centred and aligned on the lock.
b) Lock the knee, and make sure that the knee is in contact with the link rod. In this position, the cable must be slightly slack.
Torque tighten the screw to 0.8Nm using a 2 mm Allen key.
Set the position of the lock to have a 1.5 mm gap between the lock and link rod, by adjusting screw (A) using a 2.5 mm Allen
key.
Always adhere to this condition. Otherwise, you could damage the lock if the gap is greater, or there is a risk of falling if the
gap is too great.
In the unlocked position, check that the lock disengages fully, to enable bending.
If the prothesis alignment has been modified, correct the lock engagement.
The knee must be locked in the fully extended position. Otherwise, knee friction could cause deterioration of the rear link
rod.
