Function; Maintenance - Blatchford Mercury MH30 Instrucciones De Uso

4 Function

The knee is a uniaxial design comprising a knee pivot connecting a chassis to a carrier. A
hydraulic knee control sits within this frame assembly, fitted between the chassis posterior pivot
and the carrier distal pivot.
The S&S device has an adjustable yielding hydraulic support activated from knee extension prior
to heel strike and released by a hyper-extension moment at any time, usually occurring after
mid-stance.
The swing only device has no stance control mechanism and requires a combination of
geometric stability and voluntary control during stance phase.
Both devices provide an adjustable hydraulic swing phase control to accommodate variable
cadence.

5 Maintenance

An annual visual inspection is recommended. Check for visual defects that may affect proper
function.
Maintenance must be carried out by competent personnel.
The user should be advised:
• Any changes in performance of this device must be reported to the practitioner.
Changes in performance may include:
• Increase or decrease in knee stiffness.
• Instability.
• Reduced knee support (free movement).
• Any unusual noise.*
* Due to the nature of the hydraulics there may be some slight air noise from the cylinder during
the first few steps. This is not detrimental to the function of the unit and should dissipate quickly.
If symptoms persist, please consult your practitioner.
Storage and Handling
When storing for prolonged periods place the device vertically with trunnion uppermost.
Alternatively and in addition, air management may be assisted by cycling the knee control
several times with the stance resistance switched off.
Use product packaging supplied.
Cleaning
Use a damp cloth and mild soap to clean the outside surfaces.
DO NOT use aggressive cleansers.
