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 parts set 195 5002 it can be converted to a two-needle

sewing machine.

The machines are designed and may only be used for sewing materials of

textile fiber and leather.

As of 11/95 Class 195-171110 is equipped at the factory so that thread

thicknesses greater than 25/3 Nm can be sewn (airbag production).

For this, the machine and the parts kit 195 5002 each have a second hook,

this means that:

The single needle machine 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 needle machine can be equipped with the

hooks 195 4753 and 195 5055 for threads up to 25/3 Nm or with

hooks 195 4753a and 195 5055a for threads thicker than 25/3 Nm as required.

Attention!

The hook or hooks not inserted in the machine are enclosed with the machine.
