PRODUCT ADJUSTMENT AND USER TRAINING
Explain the function of the load-dependent brake to the user.
Dynamic alignment / Level ground walking
Before walking ask the user to offload the knee and release the knee
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
Brake play adjustment (Figure 10):
• Clockwise: Play is reduced. Only a small adjustment is required.
• Tighten until a slight resistance is felt. Over tightening will cause
excessive swing friction.
• Counterclockwise: Brake pre-tension is reduced.
Adjust brake sensitivity as required after adjusting brake play.
Factory setting: Tighten screw until slight resistance is felt, then unscrew
1/8 turn.
