The
purpose
of
this
Se
rvice
Manual
is
to
help
you
make
simple repairs on the ARTROMOT®-K1. Only authorized
staff may perform repairs and maintenance as the manufac-
turer’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 ARTROMOT®-K1
off before connecting or disconnecting a plug.
The locks for spiral cable for the hand-held program-
ming unit have to be closed at all times.
When you assembling with electronic parts make sure
to use ESD (Electro Static Discharge) equipment.
Only original chip cards may be used. Insert the chip
cards so that ARTROMOT® is visible.
If you have to exchange any of the printed circuit boards
including the knee electronics, hand held programming
unit, motor control or power supply electronics you have
to perform a calibration.
Possible errors: Errors will be displayed on the hand-
held programming unit as follows shown:

Mechanics
The
movable
screws
should
not
be
completely
unscre
-
wed
when adjustments are being made. Make sure
that the movable screws are tightened for operation

3.3
Others
Do
not
clean
the
housing
or
the
support
with
grease
or
oil.
No solvents may be used when cleaning the

The
following
settings
must
be
made
to
transport
the
ARTROMOT®-K1:
Set
the
packing
setting
in
the
menu
or
move
the
device
in a position of EXTENSION 0 degrees.
Switch off the ARTROMOT®-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 specified
cutout of the styrofoam and fix it with adhesive tape.
Set the femur lenght on maximum and the lower leg
setting on 45 cm.
Set the angle joint horizontal.

Move
the
two
styrofoam
parts
on
the
device
First put the power cord on the bottom of the box and
