MAINTENANCE

The device is designed for low-maintenance. The device should be
inspected every six months for signs of unusual wear, by a prosthetist
familiar with the product.
If the knee is subjected to excessive moisture or corrosive environment,
it's recommended to clean and lubricate the knee frequently.
Cleaning
Wipe knee with soft cloth moistened with small amount of kerosene.
DO NOT use solvent stronger than kerosene. If kerosene is not available,
use general purpose oil (3 in 1) or sewing machine oil.
Precaution: Do not dip knee or pour solvent over knee. Bearings and
seals may be damaged.
Precaution: Do not use compressed air to clean knee. Air forces
pollutants into bearings and may cause malfunctions and wear.
Lubrication
Two sets of roller bearings are visible, see Fig. 2 (11). Place a few drops of
machine oil on the roller bearings (general purpose oil (3 in 1) or sewing
machine oil can also be used). Move the knee several times and wipe off
excessive oil with a soft cloth. No other parts need external lubrication.

WARRANTY

The device is warranted against defective materials and workmanship for
18 months.
