3. Match needle thread to material thickness and use left-torsion
threads. Right-torsion threads will not produce so nice stitches
4. The bobbin thread should be thinner or softer than the needle
thread.
Replacing the needle
1. Conduct the needle bar to its topmost position.
(Turn the side handwheel clockwise.)
2. Loosen the screw 33, fig. 9.
3. Remove the needle from the needle bar by pulling it downwards,
4. Insert new needle with the groove facing to the left and retigh-
ten the screw 33.
Use correct needle hole
According to the needle thickness either of the two needle holes
in the pivot-mounted throat plate can be used.
1. For thick needles = large stitch hole
For thin needles = small stitch hole
2. Depress the pushbutton 21, fig. 7, and turn the throat plate
until the appropriate needle hole is underneath the needle.
Ensure that the pin 34 snaps again in the hole 35.

Unpacking
1. Check the packing for darnage in the presence of the carrier .
2. Check sewing machine, stand and accessories for any possible
transport darnage.
3. Immediately notify any darnage in the presence of the carrier
Assembly
1. Check the stand designation.
2. Fasten the sewing machine to the stand by screws according
to figs. 11-13. These illustrations serve as mounting instruc-
tions and show how the respective assembled stands should
look like.
3. Place the driving belt on the sewing machine driving pulley
and place the small stand flywheel 100, figs. 11 and 12.
4. Tension the V -belt as required as swinging out the motor .
Cleaning and oiling
1. Depress the push button 21, fig. 1 .Swing the throat plate 9
to the rear .
2. Using a clean cloth, remove anti-corrosion grease and dirt
from all components.
3. Oil alllubricating points marked by arrows in figs. 3 and 4.
4. Use our oil with following properties:
Viscosity at 400 C cSt: 65; E = 8.6
Viscosity at 50° C cSt: 42; E = 5.6

Removing the shuttle
1. Move the needle bar to its topmost point by turning the
handwheel (not in machines with stop motor. Here the
needle stops always in its upper position).
2. Depress the pushbutton 21, fig. 7 and, at the same time,
swing the throat plate 9 to the left.
3. Remove the shuttle 36.
Winding the bobbin thread
1. Pull the knurled screw 6, fig. 5, forwards and turn it until
the pin rests, the machine stops and the handwheel runs idle.
In machines with stopmotor the handwheel cannot be dis-
connected. The sewing mechanism continues operating.
2. Pass the bobbin thread from the reel 37, fig. 5, through
the thread guide 38,
3. between the disks of the tension 39.
4. Wind the thread around the bobbin 40.
5. Slip the bobbin on the bobbin winder shaft 41.
6. Loosen the screw 42, swing it down and tighten (in this way
the winder wheel will be pressed against the handwheel and
will follow its rotation).
7. By means of the handle 101 turn the handwheel until the
bobbin is filled.
8. Loosen the screw 42, swing it upwards and tighten.
9. Remove the filled bobbin.
Inserting the bobbin, threading the bobbin thread
Small shuttle
1. Insert the bobbin 43 so that the thread is unwound as shown
in fig. 6, on the left.
2. Pass the thread through the bobbin slit 44
3. into the slit 45,
4. underneath the tensioning spring 46 and
5. approx. 8 cms through the hole 47.
Threading the needle thread
1. Pass the needle thread from the reel as shown in fig. 2.
2. When passing the thread through the needle bar hole 1 place
the about 25 cm long thread end in the threading wire SUp-
plied with the standard accessories and pass the wire through
the hole downwards. Then hold fast the needle thread. pull
back the threading wire and proceed as shown in fig. 2.
Large shuttle
1. Insert the bobbin 48 so that the thread is unwound as shown
in fig. 6, on the right.
2. Pass the thread through the hole 49,
3. underneath the tensioning spring 50,
4. through the hole 51 and
5. approx. 8 cms through the hole 52.
6. Slip bobbin brake spring 53 over the bobbin (so that it exerts
a slight pressure on the latter).
Inserting the shuttle
1. Place the shuttle 36, fig. 7, into its cage and place the protrud
ing thread end to the rear into the recess 54.
2. Depress the push button 21 and swing back the throat plate 9
until the pin 34 engages (release at the same time the push
button21).
Needle and thread
1. Use for Adler 30-10 the needle system 332 L and for Adler
30-50 and 30-70 the needle system 332 LLG.
2. General rule for needle size :
If the thread jams in the long groove use a thiclser needle.
If the thread has too much clearance in the long groove use
a thinner needle.
