Cleaning the Looper Threader Pipe
Use the looper threading wire to clean the pipe of the looper
threader device.
Set the Threading/Sewing switch to “Threading” position (A)
by turning it to the right.
Turn the handwheel slowly toward you until the mark on the
wheel matches the mark on the cover (B). The hand wheel will
click and is locked in threading position.
Take the looper threading wire and push the straight end (not
the loop end) through the looper threader hole until it comes
out from the the hole of the looper tip (C).
Use a 60wt thread about 24” (60cm) long to clean the looper
threader pipes. Pass the thread through the loop of the loop-
er threading wire until the loop is at the halfway point of the
thread (D).
Carefully pull the end of the looper threading wire until the
thread comes out from the hole of the looper tip.
Pull the thread until it is all the way through the threader pipe.
Repeat the above procedure 2-3 times.
With the machine unthreaded, raise and lower the looper
threader lever 4-5 times to clean out the remaining lint (E).
Set the Threading/Sewing switch to “Sewing” position (F).
Close the front cover.
Note:
• Clean the looper threader pipe once every 10 hours of use or when the
looper threader does not work well.
• You can also use an compressed air duster or camera dust blower to
clean the looper threader pipe.
Turn off the main power switch and unplug the machine.
