Maintenance

To maintain optimum performance, a periodic inspection for unacceptable noise, play and stabilityis recommended.

The period between inspections is determined by factors such as the activity of the user,frequency of usage and the stability setting of the knee.

At these inspections:Check condition and satisfactory operation of thigh release cable.Dis-assemble, clean and re-assemble as shown on pages 3 & 4.

As a guide, if the setting is 6 clicks or above and the user averages 600,000 steps per annum,an annual inspection is recommended.

If the stability setting is less than 6 clicks and/or the user averages fewer than the averagenumber of steps, the period inbetween inspections may be longer.

The use of a Limb Activity Monitor (LAM2) is recommended to determine step count.

Adjustment and maintenance must be carried out by competent, trained personnel.If in doubt contact Blatchford Products Limited.
