Maintenance Instructions; Legal Information - Otto Bock 3R32 TITAN Instructions For Use Manual

5 Cosmetic foam cover
Use Foam Cover 6R6 (3R6, 3S106) for Joint 3R23 and 3R32.
Attention!
Do not use talcum powder to eliminate noise in the cosmetic foam cover. Talcum draws
out grease from the mechanical components. This causes considerable mechanical
malfunctions and can result in blockage of the knee joint, in turn leading to the fall of
the patient. Therefore, using talcum with this medical device will render any warranty
claims against the manufacturer null and void.
Note
To reduce friction and to eliminate noise, apply 519L5 Silicone Spray directly onto the
contact surfaces of the cosmetic foam cover.

6 Maintenance instructions

Attention!
Do not use any aggressive cleaning agents since they could cause damage to bearings,
seals and plastic parts.
Do not disassemble the knee joint! If you have a problem, please send the joint to
Ottobock.
Attention – Please inform your patients !
The knee joint function can be altered by environmental conditions and type of use. To
avoid risk to the patient, the knee joint should not be used after noticeable functional
changes have taken place. Noticeable functional changes may include, among others,
poor response, incomplete extension, diminished swing phase control or stance phase
stability and abnormal noises.
Action to be taken:
Have the prosthesis examined at a specialist workshop.
Ottobock recommends readjusting the knee joint settings once the patient has gotten used to the
prosthesis. The duration of this breaking-in period may differ from patient to patient. Check the
knee joint for wear and proper function at least once a year and make adjustments if necessary.
When doing so, pay special attention to the resistance to movement and to the development of
unusual noise. A complete flexion and extension must be ensured.
