2. Adjusting the locking positions
2.1 General notes
With the help of the locking positions an easy adjustment of the needle
motion to the hook and spreader motions is possible.
When the arm shaft is in s taking-out position, the rotary thread take-up
disc and the eccentrics for the spreaders, the hooks and the
connecting stitch have to be in staking-out position, too.
The positions have been set by the manufacturer in s uch a way that
standard material can be sewn with the 559.
If you want to use other needle sizes, thread sizes or materials, you
may have to set positions slightly differing from the staking-out
position.
The locking pegs are included in the accessories of the machine and
have a diameter of 5 mm.
