The stop, needle bar frame
Requirements
The stop must not prevent the needle reaching
the full zig-zag but should stop the needle from
going outside the needle slot in the stitch plate.
Check and adjustment
Connect the machine and turn on the main
switch. Turn the handwheel until the needle is at
the highest position. Insert the service cassette
and press the key under 140, i.e. so that 5.0 is
indicated in the digital window. Turn the
handwheel 2-3 revolutions. The needle will move
to a left-hand position, which is a cog division
outside the left zig-zag position. Set the stop in
the face plate by means of the screw (6/29) with
the least possible play. Observe the movement
of the needle, press the button for straight
stitching and set the left starting position. Check
that the needle bar frame has slight play against
the stop. Press the mirroring button and check the
right-hand position in a corresponding way.
