The purpose of this Service Manual is to help you make
simple repairs on the OptiFlex -K1. Only authorized staff may
perform repairs and maintenance as the manufacturer’s
warranty and liability would otherwise be invalidated.
Only original parts may be used for servicing in accordance
with the attached spare parts list.

No plugs may be connected or disconnected while the
unit is switched on. Always switch the OptiFlex -K1
off before connecting or disconnecting a plug.
The locks for spiral cable for the hand-held programming unit have to be closed at all times.
When you assembling with electronic parts make sure
to use ESD (Electro Static Discharge) equipment.
If you have to exchange any of the printed circuit boards
including the knee electronics or motor control you have
to perform a calibration.
Possible errors: Errors will be displayed on the handheld programming unit as follows shown:

3.2 Mechanics
The movable screws should not be completely unscrewed when adjustments are being made. Make sure
that the movable screws are tightened for operation
and transport.
The frame is unstable:
Possible cause: Bolt / screws missing or loose. Tighten
the screws / bolts.
3.3 Others
Do not clean the housing or the support with grease or
oil.
No solvents may be used when cleaning the
OptiFlex-K1.

in a position of EXTENSION 0 degrees.
Switch off the OptiFlex-K1.
Remove the power cord and disconnect the hand
held programming unit.
Only use original packaging for transport.
Put the hand-held programming unit into the extra box.
Set the femur lenght on maximum and the lower leg
setting on 42 cm.

1.
Switch on the OptiFlex -K1. Press the two outer control (Extension/ Flexion)
simultaneously.
Display: Software version VX.X XX.XX.XX (X = optional) Keep on pressing.
Display: Artromot K1 Classic
2. The maximum range of motion for Extension/ Flexion is -10 to 120 degrees.
Check the angle in position 0 degrees. Tolerance +/- 5 degrees.
Check the angle in position 60 degrees. Tolerance +/- 5 degrees.
Check the angle in position 100 degrees. Tolerance +/- 5 degrees.
3. Check the emergency-off function.
Start the OptiFlex K1 in any mode.
Press any control, the OptiFlex- K1 will stop immediately.
Check this for all controls.
4. Checking the "PAUSE" function.
Select the following settings:
Extension = 10 degrees
Flexion
= 90 degrees
Speed
= 50%
Pause
= 10 seconds
Start the OptiFlex-K1.
At the reversal points (at 10 / 90 degrees) the pause must be lasting 10 seconds
(+/- 2 seconds).
The speed is substantially lower than in a 100% setting.
5. Start the OptiFlex -K1 in the motion range between –10 to 120 degrees.
Set the speed to 100%.
Both extreme points should be reached within 45 – 65 seconds.
