6.16 Setting the stitch length
The special sewing machines 867 are, depending on the subclass,
equipped with two setting wheels. Thus, two different stitch lengths
can be sewn, that are activated by actuating a key (see chapter 6.16).
The two stitch lengths are set with the setting wheels 1 and 2 on the
machine arm.
–
Set the higher stitch length with t he upper setting wheel 1.
Setting 1 = min. stitch length
Setting 12 = max. stitch length
–
Set the smaller stitch length with t he lower setting wheel 2.
Setting 1 = min. stitch length
Setting 12 = max. stitch length
The stitch length are the same for both, forward and backward
sewing.
–
For the manual sewing of tacks, push the stitch regulator lever 3
downward.
The machine sews backward stitches as long as the stitch
regulator lever 3 is being pushed.
Hint
In order to facilitate the setting of stitch lengths, the stitch length that
remains unchanged should be activated with key 2 (see chapter 6.16).
CAUTION Danger of breakage!
The stitch length set with the lower setting wheel 2 must not exceed
the stitch length set with the upper setting wheel 1.
