2-2 Replacing the needle 

When  replacing  the  needle, check  the  needle carefully  to 
see that the scarf is turned to the left of the machine (see 
the illustration). 

 

 

 

 

 

 

 

 

 

 

 

 

 

< Note > 
When  replacing  the  needle,  be  sure  to  turn  off  the 
machine.    A  clutch  motor  continues  running  for  a  while 
after  the  machine  is  turned  off.    Therefore  keep  on 
pressing the pedal until the machine stops.

2-3 To thread the machine 

Thread the machine correctly by referring to pages 3 to 4. 
Incorrect  threading  may  cause  skip  stitching,  thread  breakage  and/or  uneven  stitch 
formation.    When  threading  the  looper,  tilt  the  looper  holder  toward  the  front  of  the 
machine using the looper drawing bar. 

 

How to tilt the looper toward the front   
1.

 

Bring needle bar A to the top of its stroke. 

2.

 

Pay out the needle thread from the spool by pressing a finger down on needle threads 
B. 

3.

 

Pull looper drawing bar knob C out to the left so that the looper holder is tilted toward 
the front of the machine. 

After the machine is  threaded, replace the looper by pressing looper holder D into  the 
machine until it clicks. 

 

 

 

 

 

 

 

 

< Note > 

The looper pops out of the machine as soon as knob C is pulled, so do not bring your fingers 
close to the looper.
