4 Handling
4.1 Connecting the internal adapter with tube to the tube clamp ad-
apter
The Tube Adapter must be shortened as necessary based on the amputee's
measurements. This must be done correctly, as noted below, to avoid dis-
torting the tube. Due to the close tolerances of quality Ottobock adapters,
a distorted tube will not fit easily into the Clamp Adapter.
Attention!
Do not clamp the tube in a vise, or it may become permanently
disorted!
The cut surface must be perpendicular to the long axis of
the tube (ill. 1). Use of the 719R2 Tube Cutter or equivalent is
recommended.
