Precautions for threading the loopers
IMPORTANT
- Use the air threading pushbutton only for
threading. Do not use the air threading
pushbutton for any purpose other than
threading.
- Do not insert anything other than thread (or the
threading wire) into the looper thread insertion
hole.
Otherwise, threading may no longer be
possible, or damage may result.
- Do not allow liquids such as oil to adhere to the
air threading pipes.
Otherwise, threading may no longer be
possible, or damage may result.
- When using the air threading pushbutton, do
not look into or block (for example, with your
finger) the hole at the end of the looper.
- Do not try to forcefully close the front cover
without returning the air threading switching
lever to the position where the pipes are
separated. Otherwise, damage may result.
NOTE:
Cutting the tip of the thread with scissors makes
it easier to insert it into the looper thread insertion
hole.
Any thread can be used for threading.
With air threading, it may not be possible to use
woolly nylon threads or thick threads to thread the
loopers. See "CHAPTER 3 When not to use air
threading".
