This service manual is to perform some repairs on
ARTROMOT®-K3 products. Repair and maintenance work
may only be carried out by authorised persons, as other-
wise all warranty services and liabilities shall be void.
It is not allowed to utilize any other spare part which is
not mentioned in chapter 6.
3.1 Electronic and cable
■Make sure that the characteristic values of your power
supply correspond to the voltage and frequency data
indicated on the power adapter.
■Error possibilities, showed by the Hand-held pro-
gramming unit:
Error 1: Spiral cable of the knee case is broken or not
connected
--> Verify the connection of the spiral cable or replace
the spiral cable.
3.2 Mechanics
■Do not loosen the knurled handles completely for any
adjustment. For operation or transport, make sure that
the knurled handles are tight.
3.3 Others
■Do not clean the housing or the support with grease
or oil.
■Do not utilize any solvent for cleaning the
ARTROMOT®-K3.

1. History

Preparations for transport the ARTROMOT®-K3 has to be
done.
■The first step is to move the device in a maximum
position of EXTENSION = -5 degrees.
■Remove the power adapter and put this part in a
separate pad.
■Loosen the 2 knurled handles (Pos. 6.2), pull out the
ankle joint (Pos. 4.x) and put the ankle joint just the
other way round.
■Protect the hand-held programming unit against vibration
and damage and put the hand-held programming unit
in a separate pad.
■Make sure, that all of the knurled handles are tight.
■For transportation, use the original packaging.

7. How to perform the repair
7.1 How to remove the casing (Pos. 3.12)
■Move the ARTROMOT®-K3 in a position of approximately
110 degrees.
■Turn the power OFF at the ARTROMOT®-K3 and remove
the power adapter.
■Hit the 4 pins of the split rivet (Pos. 3.24) inwards.
■Remove the 2 covering plates (Pos. 3.22)
■Loosen the 2 countersunk screws (Pos. 3.50) and remove
the casing.
■Remove the 4 pins of the split rivet, which are inside the
casing.
■If you have exchanged any of the printed circuit boards
including the knee elec-tronics and the hand held pro-
gramming unit or any parts of the drive technology (Pos.
3.x), you have to perform a reference run. See chapter 7.4
■Finally, a function- and safetytest has to be performed.
7.2 How to exchange the hand-held programming unit
(Pos. 1.2)
■Remove the casing. See chapter 7.1
■Pull out the connector of the hand held programming unit.
Attention: Use your ESD (Electro Static Discharge)-
equipment.
■Put in the connector of the new hand held programming
unit.
■Rebuild the casing.
■Perform a reference run. See chapter 7.4
■Finally, a function- and safetytest has to be performed.
7.3 How to exchange the motor electronics
(Pos. 1.3 and 1.6)
■Remove the casing. See chapter 7.1
■Pull out the required cables at the printed circuit board
(Pos. 1.6)
Attention: Use your ESD (Electro Static Discharge)-
equipment.
■Exchange the defect printed circuit board.
■Put in the cables at the same position. (Pay attention to
the code)
■Rebuild the casing.
■Perform a refernce run. See chapter 7.4
■Finally, a function- and safetytest has to be performed.
7.4 How to perform a reference run.
(Reference run connector: 0.0031.007)
■Move the ARTROMOT®-K3 in a position of approximately
10 degrees.
■Turn the power OFF at the ARTROMOT®-K3.
■Adjust a maximum femur length.
■Open the housing of the hand-held programming unit
vis-à-vis to the spiral cable side. At the printed circuit
board is an unused socket. Insert the reference run
connector at this socket. (Pay attention to the code)
■Turn the power ON at the ARTROMOT®-K3.
■The display shows „REFERENCE RUN"
■Press „START"
■After about 2 minutes, when the ARTROMOT®-K3
reached both points of changing direction, (first minimum
at EXTENSION = -5 degrees afterwards maximum at
FLEXION = 127 degrees) the ARTROMOT®-K3 will stop at
EXTENSION / FLEXION = 110 degrees.
Attention: It is important to push or pull at the femur
bow so that in direction Flexion the ARTROMOT®-K3
reach the mechanical stud. (approximately 3 cm in front of
the right/left cover). (Pos. 2.8/2.9)
■Pull out the reference run connector.
■Turn the power OFF at the ARTROMOT®-K3 and close
the housing of the hand-held programming unit.
■Finally, a function- and safetytest has to be performed.

1. Turn the power ON at the ARTROMOT®-K3 and press "SET" .
Display: Software Version K3 V33 070600 (for the new generation of
hand-held programming units)
No display change (for the old generation of hand-
held programming units)
2. The set range of motion for Extension/Flexion is from -5 to 110 degrees.
Verify the angle in a position of 0 degrees with a tolerance of +/- 5 degrees.
Verify the angle in a position of 60 degrees with a tolerance of +/- 5 degrees.
Verify the angle in a position of 105 degrees with a tolerance of +/- 5 degrees.
4. Safety - OFF Functions.
Start the ARTROMOT®-K3 in a continuos mode.
Press any of the buttons (with the exception of "SET", "+" and "-") to stop
the motor immediately. Verify this for all buttons.
6. Perform the following settings.
Extension: -5 degrees
Flexion: 110 degrees
Pause Ex.: 5 sec.
Pause Flex.: 10 sec.
Force: 45 kp
Speed: 100%
Adjust a maximum femur length.
7. First press "STOP" and afterwards press "START".
The ARTROMOT®-K3 should then reach both points of changing direction
within 50 to 65 seconds.
8. Change the speed to 50% and repeat test 7
The ARTROMOT®-K3 should then reach both points of changing direction
within 105 to 125 seconds.
9. Verify the settings for "Pause Ex." and "Pause Flex."
The tolerance for both is +/- 3 seconds.
