Howto adjust the thread length remaining in the needle after thread trimming:

o In order to prevent the needle thread from slipping

. face of the materialat the start of

sewing,

a proper length of needlethreadmust beleft in the

needle eye after thread trimming.

o The thread length is adjusted by the thread tension No. 1.

o It is possible to provide the thread trimmer with different timing of action to trim a synthetic

thread from that of cotton thread. Consult withour distributorsor agentsin your areafor this
