Function; Maintenance - Blatchford EliteVT Serie Instrucciones De Uso

4 Function

This device comprises an e-carbon toe and independent heel spring. The carrier assembly
contains a spring component which 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.
Heel and toe springs are attached to the carrier assembly using titanium screws. The foot is
wrapped in a UHM PE sock which is in turn surrounded by a PU foot shell.

5 Maintenance

Visually check the device regularly.
Report any changes in performance of this device to the practitioner/service provider e.g.
unusual noises, increased stiffness or restricted/excessive rotation, significant wear or excessive
discoloration from long term exposure to UV.
Inform the practitioner/service provider of any changes in body weight and/or activity level.
Cleaning
Use a damp cloth and mild soap to clean outside surfaces, do not use aggressive cleansers.
The remaining instructions in this section are for practitioner use only.
This maintenance must be carried out only by competent personnel (practitioner or suitable
trained technician).
The following routine maintenance is to be carried out at least annually:
• Remove foot shell and glide sock, check for damage or wear and replace if necessary.
• Check all screws for tightness, see Construction section; clean and reassemble as necessary.
• Check heel and toe springs for signs of delamination or wear and replace if necessary. Some
minor surface damage may occur after a period of use, this does not affect the function or
strength of the foot.
Instructions to remove the foot shell and replace the foot-springs are included in Foot Shell
Removal & Foot Spring Replacement section.
If necessary, re-lubricate the spring's bearing surfaces. To do this:
• Disassemble the device as shown in the Axial Shock Spring Replacement instructions.
• Apply 'Sapphire Endure' (928015) or equivalent PTFE loaded grease to the bearing surface,
then reassemble.
Ensure the user has read and understood all safety and user-level maintenance information.
Advise the user that a regular visual check of the foot is recommended and 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).
If this device is used for extreme activity, the maintenance level and interval should be reviewed
and if required advice and technical support sought to plan a new maintenance schedule
dependent upon the frequency and nature of the activity. This should be determined by a local
risk assessment carried out by a suitably qualified individual.
