Shaping the bars

Required tools : Vice, 2x 711S* bending irons, grinding machine, screwdriver, Loctite 241

  1. Use the 711S* bending irons for contouring the joint bar.
  2. INFORMATION: Do not use bending irons with sharp edges for the 17F32 aluminum joint bar; use only the 711S4 bending irons or bending irons with rounded edges.
  3. Contour the bar until the desired result is obtained.
  4. Observe the minimum bending radius of 10 mm (see fig. 2).
  5. Remove grooves and burrs by grinding.
  6. For final assembly, secure the joint screw with Loctite 241.

Bending the foot stirrups
> Required tools: Vice, 711S* bending iron, grinding machine

  1. Use the 711S* bending irons for contouring the foot stirrup.
  2. Clamp a bending iron in a vice and position the foot stirrup.
  3. INFORMATION: To prevent the risk of breakage, do not bend or otherwise modify the insertion zone. Adapt the foot stirrup with the bending iron.
  4. Remove grooves and burrs by grinding.

Mounting the foot stirrup
> Prerequisite: The orthotic ankle joints are disassembled. To do so, remove the joint screw and the bearing nut from the joint.

  1. Insert the contoured foot stirrup into the orthotic ankle joint.
  2. Assemble the foot stirrup and the orthotic joint with the bearing nut and the joint screw.
  3. For final assembly, secure the screw connection with Loctite 241.

Improving corrosion protection
Stainless steel
The 17F31 orthotic joint made of stainless steel has a shiny surface that is protected against corrosion. Sanding, polishing, and sintering improve the protection against corrosion.
NOTICE! Do not use polishing pastes containing iron to polish stainless steel. The micro-fine iron particles are sufficient to initiate cor­ erosion.

Aluminum
The 17F32 orthotic joint is made of aluminum.
► NOTICE! Do not carry out any heat treatment at temperatures above 200 °C.
► Do not weld! Use a screw or rivet connection.

Ottobock recommends

For sanding: 649G9 belts, free of iron oxide, 280 – 320 grit
For polishing: Polishing mop coated with Vienna chalk 649Z4 polishing paste,

non-ferrous
For surface coating:| 618T40 Sintering powder

► After sanding, polish the surfaces, paying special attention to the edges.
► Do not heat the material longer than 5 minutes at max. 150 °C for sur­ face coating.

Cleaning

Promptly clean the product after contact with:
• Water containing salt, chlorine or soap, perspiration, urine or splashed water (e.g. after rain), and soiling.

  1. Rinse the product with clear fresh water.
  2. Dry the product with a cloth or allow it to air dry. Avoid exposure to direct heat (e.g. from an oven or radiator).
