Setting The Stitch Length - Dürkopp Adler M-Type 869 Serviceanleitung

6.15 Setting the stitch length

26
4
The special sewing machine 869 has, depending on the subclass, as
standard equipment two setting wheels. Thus, two different stitch
lengths can be sewn, that are activated by actuating the key 4 (see
chapter 6.15).
The two stitch lengths are set with the setting wheels 1 and 2 on the
machine arm.
–
Set the higher stitch length with the upper setting wheel 1.
Setting 1 = min. stitch length
Setting 9 = max. stitch length
–
Set the smaller stitch length with the lower setting wheel 2.
Setting 1 = min. stitch length
Setting 9 = 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
downwards.
The machine sews backward as long as the stitch regulator lever 3 is
pressed down.
Please note:
In order to facilitate the setting of stitch lengths, the stitch length that
remains unchanged should be activated with key 2 (see chapter 6.15).
ATTENTION! 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.
