8.4 ADJUST ZERO-POSITION
(STARTING POSITION)
– Open table top.
– With a long hexagon-socket screw wrench (placed
through hole in side wall) turn coupling in direction
of arrow, until the aggregate is in the 0° position
(perceptible engagement when the three clamps
are in the lower position).
– Mark coupling above in the centre (15/1).
– Remove hexagon-socket screw wrench and close
table top.
– Turn Main switch to position „1“.
– Toggle switch (3/6) on.
– Activate push-button „Reset“ (3/1). The aggregate
moves into the 0° position.
– Open table top.
– If the marker (15/1) on the coupling is located in the
„+“ direction, the proximity switch B1 (15/3) must be
adjusted downwards. For this purpose the two
hexagon screws (15/2) must be loosened.
– If the marker on the coupling is located in the „–“
direction, the proximity switch B1 must be adjusted
upwards.
– Repeat the sequence until the marker is located in
the above middle of the coupling.
