1. Product Description
1.1 Short Description and Proper Use
The special sewing machine 195 is a single needle-double chain stitch machine with lower transport and an upper transport with alternating pressure feet. The hook of the 195 is set crosswise to the direction of sewing (Crossline). With the part s set 195 5002 it can be converted to a two-n eedle sewing machine.
The machines are designed and may only b e used for sewing materials of textile fiber and leathe r.
As of 11/95 Class 195-171110 is equipped at the factory so that thread thicknesses great er th an 25/3 N m ca n be sewn (ai r bag pr o du ct ion) . For this, the machine and the pa rts kit 195 50 02 eac h have a second hoo k, this means that:
The single needle machi ne can be equipped with hook 195 4753 for threads up to 25/3 Nm or with
hook 195 4753a for threads thicker than 25/3 Nm as required. The dual n e edle machine can be equipped with the hooks 195 4753 and 195 5055 for threads up to 25/3 Nm or with
hooks 195 4753a an d 19 5 50 55 a for threa ds thicker than 25/ 3 Nm as requ ir e d.
Attention!
The hook or hooks not inserted in the machine are enclosed with the machine.

3. Operating the Sewing Machine
3.1 Threading the Needle Thread
1
Caution Risk of Injury!
Turn off main switch before threading.
- Thread the needle thread as shown in the illustrations.
Important!
By machines with thread trimming it is essential that the nee dl e th r ea d be thr e ad ed through the pre-tensioners (1).
13
3.2 Needle Thread Quantity for Sure Stitch Formation
1
a)
b)
With elastic sewing thr e ad s, e.g. synthetic fiber threads, a certain needle thread quantity must be pulled out for sure stitch formation.
This occurs in the low posi ti on of th e take-u p lever in conjunctio n wit h th e th rea d r eg ul ator 1.
For this the thread regulator is set as follows:
Bring the thread regulator into its lowest position.
Adjust the thread regulator.
With elastic th rea ds : The thread hole must be visible below the thread regulator. Thread the needle to the
With non-elast ic thr e ads, e.g. cotton: Thread hole should be visible above the thread regulator. Thread the needle thread to the Illus. b

3.3 Threading the Bobbin Thread
Caution Risk of In ju r y !
Turn off the main switch be fore thre adin g.
Lift the thread holder 1 out of its catch.

Draw the thread through the hook holes.
Close the hook holder.

3.4 Setting the Thread T ensions
The thread tension of the needle thread must be higher than that of the bobbin thread. The control knob for the bobbin thr ea d te ns io n th us has a spring of thinner wire.
Too high thread tensions cause a puckering of the material.
Too low bobbin th read tensio ns can caus e faulty stitches.
For setting a greater thread quantity in the seam see Sectio n 3.5.
Furth ermore, one ca n work with or without pneumatic tension opening during the stroke of the sewing foot.
The tension opening is necessary when the sewing material with thread is to be pulled forward under the sewing foot. Here the arm cover must be removed and the coupli ng plug in se rted into th e preattache d coupling socket.
Attention!
When sewing corners with sewing foot stroke a loose stitch results. Thus, pneumatic tension opening should only be used when there is no sewing foot stroke during the course of the seam.

3.5 Setting the Hook Thread T ake-up

The thread take-u p 1 pr ovi de s for an aut om at ic adjustment of the th r ea d qu anti ty to th e se t st itch length.
Because of this , stitch pull and stitch formation are always optimal for every stitch length, also for stitch condensation. The drawn-in thread quantities can be altered for each type of seam.
Results with ou t al te r i ng the th r ea d te ns io ns ar e: a) tight
b) normal c) highly elastic (ballon stitch) seams.
Loosen screws 2.
Adjust the thr ea d ta ke-u p. Direction 0 tighter seam Direction 5 elastic seam.
Important!
1) With extreme settings, e.g. a smallest possible stitch length and a hi gh es t po ss ible th r ea d quan ti ty (elastic seam ) , car e mus t be taken th at a pos it ive stitch of the needle int o th e th rea d de lt a is possible. Faulty stitches can occ ur by too la rge hook thread quantities.
2) If the stitch length is greatly increased by the settings described under 1, it is necessary to set back the thread guid e in the dir e ct ion 0. Otherwise the hook thr ead may jump off of the thread take-up disc.

3.6 Setting the Pressure Foot Stroke
Attention!
The machine doe s no t have automa ti c r evolution reduction. When sewing with a large pressure foot stroke it is impera ti ve to manua ll y red uc e th e number of revolutions. Too high revolutions become obvious through louder sewing noise.

3.7 Edge trimmer activating and deactiv ating
The edge trimmer off Cl. 195-671110 may be actuated at any time. It’s upper knife is such as formed that also a save cutting aktion is achieved at activating while sewing.

Attention Danger of injuring
Don’t reach into cutting zone at activating the trimmer. Remove finger guard only for repair aktions. immediately replace finger guard at damages.
For activating of the trimmer pull lever 1 downwardly, for deactivating push lever upwardly
