brake and flex the knee a few times to experience the brake function.
Brake sensitivity (Figure 8)
The knee brake mechanism has a factory setting suitable for most users.
Verify the activation of the stance brake.
Factory setting: Unscrew and tighten until a slight resistance is felt. Then
tighten further half turn.
Extension assist setting (Figure 9):
• Right turn: Increases extension assist.
• Left turn: Decreases extension assist.
Factory setting: three moves from max extension assist
