MAINTENANCE

The Total Knee 1900 is designed for low-maintenance. It is warranted
against defective materials and workmanship for 24-months. We
recommend:
• Total Knee 1900 be inspected every six months for signs of unusual
wear, by a prosthetist familiar with this product.
• Stance flexion bumper must be replaced if cracked or worn,
depending on patient´s activity level.
• If 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 (3in1) or sewing machine oil.
• DO NOT dip knee or pour solvent over knee. Bearings and seals may
be damaged.
• DO NOT use compressed air to clean knee. Air forces pollutants into
bearings and may cause malfunctions and wear.
LUBRICATION (Figure 13)
Three sets of roller bearings are visible. Place a few drops of machine oil
on the roller bearings(general purpose oil (3in1) 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.
