Fastening the hand-
wheel a. synchronizer
To screw on the handwheel 4 proceed as
follows:
Turn the arm shaft until the timing pin 2
that is slid through the hole 3 in the
housing can be inserted right into the
deepest slot of the disk on the arm shaft.
Screw on the handwheel such that its
mark "A" is level with the timing pin 2.
Screw on the synchronizer 5.
When the synchronizer must be screwed
on again after a repair, it is necessary to
redetermine its reference position (see
point 9). This is however no longer
necessary, when the following measures
are taken:
Insert the pin of the accessories into the
hole of the handwheel.
Bore an 8-mm-deep hole 6 into the
synchronizer 5.
Screw on the synchronizer such that the
pin of the handwheel is in its hole.
Fasten the thread stand.
Screw on the control panel.
