Maintenance - Otto Bock 17BK2 Series Instructions For Use Manual

Locking the dynamic unit
INFORMATION
If the dynamic unit is not used for extended periods of time, we recom­
mend disengaging the locking mechanism to prevent the spring from wear­
ing out prematurely.
The switch (item 6) can be used to lock the dynamic unit in an angular posi­
tion from -20° to 90° under tension.
1) Bring the orthosis to the desired angle position and hold it there.
2) Slide the switch (item 6) until the red dot is displayed.
3) Move the orthosis into extension until you hear the locking mechanism
engage.
→ The orthosis is locked in the flexion and extension directions.
Releasing the lock
1) Slide the switch (item 6) until the green dot is displayed.
2) Flex the orthosis against the spring force until you hear the lock disen­
gage.
→ The preset spring force of the dynamic unit is activated.

After contact with water containing salt, chlorine or soap, or if they get dirty,
the orthotic joints must be promptly cleaned.
1) Rinse the orthotic joints with clean fresh water.
2) Dry the orthotic joints with a cloth or allow them to air dry. Avoid expos­
ure to direct heat (e.g. from an oven or radiator).
