Correct thread tension
Your 4874 automatically sets the thread
tension, stitch length and differential feed
for each stitch type. However, the type of
fabric, the quality of the thread and the
needle size all affect seam formation to
some degree, so it may be necessary to
adjust the thread tension settings.
Also check that your 4874 is threaded
correctly and the threads are all the way
in the tension discs before adjusting the
tensions. The stitch length or seam width
may need to be adjusted to accommodate
the fabric you are sewing.
To change the automatic thread tensions,
press one of the tension buttons + /-. The
program memory will open. Now you can
change all your settings using the +/-
buttons as you wish. If you press memory
selection button P repeatedly you will be
returned to the main menu; the changed
setting will not be saved.If no changes
are made within 10 seconds, the display
automatically switches back to the main
menu.
You can also save your new tension
settings. See chapter 3 for instructions on
how to do this.
Note: The thread tensions
for the top cover and deco
cover threads (42) must be set
manually. The settings can be
found on the stitch program
sticker behind the front cover.
