Maintenance - endolite EchelonVT ECVT30R84S Gebrauchsanweisung

3 Function
EchelonVT comprises a hydraulic body assembly containing adjustable hydraulic valves.
The valves can be independently adjusted to increase and reduce hydraulic resistance to
plantarflexion and dorsiflexion.
The proximal part of the hydraulic body assembly contains a spring component that allows
the pyramid tube to deflect and/or rotate through a limited range under an axial and/or
torsional load. When the load is removed the spring returns to its original position. The effect
of this movement is to attenuate any shock forces that would otherwise be transmitted to the
residuum/socket interface both in axial and rotational directions.
The hydraulic body assembly is connected to a carrier assembly via two pivot pins.
springs are attached to the carrier using titanium and stainless steel screws.
in a UHM PE sock which is in turn surrounded by a PU foot shell.

4 Maintenance

Maintenance must be carried out by competent personnel.
It is recommended that the following maintenance is carried out annually:
• Check for visual defects that may affect proper function
• Clean and relubricate bearing surface. Use Sapphire Endure (928015) or equivalent PTFE
loaded grease
(see Section 8 Maintenance Instructions).
• Remove the foot shell and glide sock, check for damage or wear and replace if necessary.
• Check all screws for tightness, clean and reassemble as necessary.
• Visually check the heel and toe springs for signs of delamination or wear and replace if
necessary. Some surface damage may occur after a period of use, this does not affect the
function or strength of the foot.
Any changes in performance of this device must be reported to the practitioner. Changes in
performance may include:
• Increase in ankle stiffness
• Changes in axial or torsional stiffness
• Reduced ankle support (free movement)
• Softening of springs
• Excessive play in bearings
• Any unusual noise
The user should be advised to contact their practitioner if their condition changes.
The practitioner must also be informed of any changes in body weight and/or activity level.
The user should be advised that a regular visual check of the foot is recommended, signs of wear
that may affect function should be reported to their service provider (e.g. significant wear or
excessive discoloration from long term exposure to UV).
Cleaning:
Use a damp cloth and mild soap to clean outside surfaces. Do not use aggressive cleansers.
