► Prior to the thermal treatment of the product, remove all temperature-
critical components (e.g. plastic parts).
5 Preparing the product for use
Orthosis alignment
►
Select suitable materials to reduce the torsional stress on the orthosis.
►
Record the parts and lot number in the patient file to enable tracing in
accordance with product liability law.
► Use the 743Y57* alignment insert for the correct alignment of the orthot­
ic joints.
►
When using thermoplastics, additional reinforcement is required in the
area of the calf.
Protecting the product against environmental influences
► Apply a protective coating to the aluminium bars or polish them slightly.
► The steel that is used can rust. Apply a cover or paint to the product for
extra protection before handing it over to the patient.
► The joint mechanism must be protected against dirt by a suitable protec­
tive device (e.g. joint protectors) to ensure proper functioning.
Bending bars
► Align the bars with the bending irons without exposing the joint heads to
any bending load.
► The bending radius must be at least
20 mm.
The allowable bending
range is marked with a dotted laser line on the bars – do not bend
inside that range
.
► INFORMATION: Limit the bending of bars to a minimum, as
excessive bending of bars can result in loss of stability and prema­
ture breakage of the bars.
Heat treatment of bars
All bars have been heat-treated.
► Heat the bars while observing the temperature limits for aluminium of
150 °C (302 °F) and for steel of 300 °C (572 °F).
►
DANGER! Grinding and polishing the bars with much force can
create temperatures of above 100 °C. Slowly air-cool the rails and
do not immerse them in cold water for immediate cooling.
