Otto Bock Triton 1C61 Instructions For Use Manual page 22

The footshell must not be dusted with talcum powder as this would increase abrasion. Use sili-
cone spray for lubrication if needed. Replace the footshell in case it shows any damage or wear.
Inserting the foot into the footshell:
• Before inserting into the footshell, attach the tube adapter to the prosthetic foot. This facilitates
the procedure.
• Use the 2C100 Footshell Insertion/Removal tool provided by Ottobock to insert the carbon
foot into the footshell.
• Make sure that the heel of the polymer base spring locks in under the footshell heel tab.
Removing the footsell:
• Insert the 2C100 Footshell Insertion/Removal tool under the heel of the polymer base spring
which is located under the heel tabs in the posterior part of the footshell and pry the heel out
of the shell. It is then possible to pull the foot out of the footshell.

4.1.3 Static alignment optimization
If necessary, the alignment recommendations (TF modular leg prostheses: 646F219*, TT modular
leg prostheses: 646F336*) may be requested from Ottobock.
Use the L.A.S.A.R. Posture for static alignment optimisation of the prosthesis, if available.
4.1.4 Dynamic alignment optimization
Adapt the prosthetic alignment in the frontal plane (ML) and in the sagittal plane (AP) by angle
adjustments and/or sliding adjustments, in order to ensure correct heel contact, easy roll-over,
and optimal shifting of weight onto the contralateral side. For transtibial amputees please make
sure that there is physiological knee flexion during stance phase.
4.2 Using the optional heel wedges
CAUTION
Risk of falling due to change of the knee dynamics when using heel wedges.
