Pin Placement

When securing the fabric pieces using pins, insert straight
pins to the left of the presser foot. The pins will be easy to
remove and are away from the cutters.
Sewing over pins will damage and might destroy the
cutting edge of the cutters.
• When the machine is completely threaded, close the
front cover and bring all of the threads over the stitch
plate and slightly to the left under the presser foot.
• Ensure that the upper blade moves against the lower
blade correctly by turning the handwheel slowly
toward you. If the blades are not moving correctly,
check if there are any fabric or waste thread stuck
between the blades.
• Hold the threads and pull them slightly.
• Turn the handwheel toward you two to three complete
turns to start making a thread chain. Check if all
threads wind around the stitch nger of the stitch plate.
If the threads do not wind around the nger, make sure
each thread is threaded correctly.
• Continue holding the thread chain while pressing the
foot control. Sew until the chain is 5-8 cm (2-3") in
length.
• Place fabric under the front of the presser foot and sew
a test sample. Guide the fabric slightly with your left
hand while sewing. Do not pull on the fabric as this
may de ect the needle, causing it to break.

Chain off

• When you reach the end of the fabric, continue sewing
while drawing the nished fabric gently backwards
and to the left. This is called chaining off. It prevents
the threads from coming undone and prepares for the
next sewing task.
• Cut off the thread chain 2-5 cm (1-2") behind the
presser foot using the thread cutter on the left side of
the machine. Pull the threads around the thread cutter
from the back, then toward you.
Tip: When you have re-threaded the machine, always chain off
and test sew a sample to test thread tension.
Tip: The presser foot on this machine has marks to indicate the
needle position. Use this as a guide when sewing.
