Bending Bars; Heat Treatment Of Bars; Drilling Bars; Installing Mounting Materials - Otto Bock 17KL30 Series Instructions For Use Manual

Locking mechanism
► Do not adjust the locking mechanism or the orthotic joint.

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.

Drilling bars

Holes may be drilled in the bars.
► Drill the holes for the mounting material in the bars. The distance
between the hole and the outer edge of the bar must be at least equal to
the diameter of the hole.
► INFORMATION: The holes must not be repaired or filled under any
circumstances.

Installing mounting materials

► Install the mounting materials.
INFORMATION: Make sure that the mounting materials do not
obstruct the locking mechanism.
Installing the lock lever
► Screw the lock lever into the lock hammer.
Final assembly of orthosis joint
