Fig. 6. Arm tower-removing bearing protection foam
Remove the fixing foam on the horizontal bearing assembly ( Fig. 6).
Check that the bias thread is
fixed and gently rotate the horizontal bearing assembly from one to another extreme. It is only
possible to make approximately ¼ of a turn and it is normal to feel slack in the bearings.
Tube assembly:
Carefully take the tube assembly with the cable and gently position it around the horizontal bearing
assembly so that
both
vertical spikes ( points) fit into the appropriate vertical bearing cups. Then
position the tube into the armrest. ( Fig. 7&7a)

Cable assembly:
Remove cable from the tube assembly by releasing the black cable holder from the transport position
with the 1.5 mm Allen key. Fix it to the empty pin at the back of the arm tower. Fix it in such way,
that the wires will go upwards towards the tube in a loop . Be sure, that the arm tower is fixed in the
arm base, because the weight of the cable might otherwise rotate it. (Fig. 8&8a)
