When during standstill of the machine the needle is approx. 15 mm after its 
upper dead point in front of the penetration, the presser plate and the plunger 
can be moved downwards by activating the knee lever. At the same time the 
needle thread tension is vented. 

Inserting and removing the sewing material – work sequence 

For pneumatic venting also see point “5 Operating the sewing machine”. 

Now the sewing material can be inserted into the machine between stitch plate 
and presser plate. 

The sewing material cannot be removed until the last stitch has been 
completely carried out, the needle thread loop has dropped from the hook, the 
needle is again in the position mentioned above and the knee lever is activated. 

When using a sewing drive with needle height position, the positioning is 
carried out automatically. 

CAUTION IMPORTANT! 

Do not let the machine run if there is no fabric between stitch plate and 
transporter.
