Problem
Cause
Action
Relevant especially for patients with
a high body weight: Braking effect
is too aggressive; initiation of the
swing phase is difficult.
Brake sensitivity is set
too high.
Reduce brake sensitivity: Turn
adjustment screw clockwise.
Relevant especially for patients with
a low body weight: Braking effect
is insufficient; the joint becomes
unstable in the stance phase.
Brake sensitivity is set
too low.
Increase brake sensitivity: Turn ad-
justment screw counter-clockwise.
(Delivery condition = level 4 = high-
est brake sensitivity. Do not turn
the screw counter-clockwise any
further!)
4.2.3 Adjusting the Brake Slack
CAUTION
Risk of falling after adjusting the brake slack.
Adjusting the brake slack can cause the brake
to get blocked or stuck and, as a result, cause the patient to fall.
Observe the following instructions.
Upon delivery the brake slack is optimally adjusted.
Despite of correct alignment of the prosthesis (see Section 4.1) and correct brake setting it may
become necessary to modify the brake slack (see table below).
For adjusting, slightly turn the play compensation screw clockwise or counter-clockwise (Fig. 6,
item B) using 710H10=2X3 Adjustment Wrench (Fig. 1, item 2).
Problem
Cause
Action
Flexion and extension movements
are impeded when the prosthesis is
unloaded (noticeable resistance to
movement); the brake gets stuck.
Brake slack upon load
bearing is too low.
Increase brake slack: Carefully
turn the play compensation screw
clockwise.
Uncomfortable, jerky flexion and
extension movements upon load
bearing
After longer use, the
brake slack upon load
bearing is too high.
Reduce brake slack: Carefully
turn the play compensation screw
counter-clockwise.
Optimum setting (as delivered) is achieved, when there is no noticeable brake slack upon load bear-
ing and the pendulum movement of the prosthetic lower leg is not impeded during the swing phase.
4.2.4 Adjusting the Swing Phase Control
The mechanical swing phase control of the 3R93 can be set to
6
levels
by changing the tension
of the integrated spring extension assist using 710H10=2X3 Adjustment Wrench (Fig. 1, item 2).
Upon delivery the spring adjustment ring (Fig. 7, item A) is set to
level
1
.
If necessary, the spring effect can be adjusted as follows:
