If the Teflon sheet is not adhered on the
rear surface of the sewing cassette, the
top surface of the throat plate can be
stained to leave stains on the sewing
material. The Teflon sheet is a consum-
able part. It is necessary therefore peri-
odically inspect it and change it with a
new one if it has worn out.
・ The positioning block at the auto-ejec-
tor side is used as the reference. Do
not adjust it according to the jig.
・ In prior to the start of use of the sew-
ing machine, clean up the underside
and material holding plane of the
sewing cassette, top surface of the
throat plate auxiliary cover and sec-
tions 1 and 2 of the positioning block
and check to make sure that they are
free from dust. If any of them is not
clean, the material can be soiled.
