CHAPTER 7
MAINTENANCE

Cleaning

CAUTION
Turn off the machine before cleaning.
Lint accumulates when the machine is used. After using
the machine, periodically remove dust and trimmed
fabric and thread with the included cleaning brush.

Opening the material plate cover

IMPORTANT
- Before opening the material plate cover, make
sure that there is enough space on the left
of the machine and that no people or objects
obstruct the area.
- Do not apply excessive force to the material plate
cover or try raising it. Otherwise, it may be damaged.
When closing the material plate cover, be careful
that your fingers or clothing do not become caught.
- Make sure that the material plate cover is firmly
closed.
Slide the material plate cover in the direction of
the arrow to open it.

Cleaning the air threading pipes

Use the included threading wire to clean the
looper pipes.
1. Join the pipes. (See "CHAPTER 3 Before
threading the loopers".)
2. Insert the threading wire into the thread
insertion hole, and then pull out the wire
coming out of the end of the looper. (See
"CHAPTER 3 When not to use air threading".)
3. Repeat this operation several times.

Oiling

CAUTION
Turn off the machine before opening the front
cover and oiling.
For smooth and silent operation, the moving parts
(indicated with the arrows) of the machine should
be oiled periodically.
NOTE:
Always clean the lint off your machine before you
apply oil.
Oil the machine once or twice a month for normal
use. If the machine is used more often, oil it once
a week.
Use only good quality sewing machine oil.

Replacing the knives

When the knives no longer cut fabric, they must
be replaced.
Contact your authorized dealer.

Transporting

CAUTION
When transporting the machine, be sure to carry it
by its handle.
If the machine is carried by any part other than the
handle, the machine may fall or be damaged.
IMPORTANT
- Always remove the foot controller from the trim
trap when carrying the machine.
Grasp the handle to transport the machine.
