Össur OH7 KNEE Notice D'utilisation page 13

When using with a 3-arm socket adapter
• The M5 locking screw on the 3-arm socket adapter must be tightened to a torque of 10 Nm and secured with
Loctite. Use a torque wrench (5 mm Allen).
• For a later adjustment, do not unscrew the adapter with an external thread (40) by more than one turn.
Observe all the above points, otherwise the guarantee becomes null and void!
MAINTENANCE
The joint must be inspected, and repaired if necessary, at least every 6 months!
Inspect for
• the alignment
• the screw connections
• adhesion and torque of the central screw
• the suitability of the patient (e.g. max. body weight, degree of mobility)
• loss of lubricant
• damage to the joint and accessories
• AP + ML play
• the extension stop
• visual inspection of the proximal adapter for damage
• damage to the two adjustment discs when using the loop adapter
• the thread connection when using the adapter with an external thread
• when using with an IKF adapter: check for intact function, especially of the mounted buffers
• soiling with talc
• at every inspection/maintenance, the piston rod of the hydraulic system must be cleaned with a soft cloth and
mild detergent. The piston rod must then be lubricated with silicone spray or grease or with a comparable
lubricant.
CARE
• Clean the joint with a soft cloth moistened with a little mild benzene.
• Do not use any cleaning agents that are more aggressive than this, because these can damage the seals and
bushes.
• Do not use compressed air for cleaning! Compressed air can blow existing dirt into seals and sleeves, where it
causes damage and premature wear-and-tear.
