5.1 Installing the Adapter
CAUTION
Improper assembly of the screw connections
Fall due to breakage or loosening of the screw connections
► Clean the threads before every installation.
► Apply the installation torques provided.
► Observe the instructions for securing the screw connections and the
use of the correct length.
Recommended tools and materials:
>
Grinding tool, torque wrench 710D4, degreasing cleaning agent (e.g.
acetone 634A3), special adhesive and hardener 636W28
1) For prosthetic feet with wooden components, roughen the connection
surface and remove the grinding dust.
2) Mix the special adhesive and hardener well together and apply to the
connection surface.
3) Clean any soiling (e.g. caused by fat) on the metal surface of the foot
adapter to be glued with a degreasing cleaning agent.
4) Position the foot adapter on the prosthetic foot and screw it on from
below with the screw and washer (installation torque: 2 to 4 Nm).
5) After 3 to 4 hours, tighten the screw with the required installation torque
(see table).
6) Leave the glued surface to harden (16 hours at 20 °C - the time
increases for lower temperatures).
