IMPORTANT SAFETY INSTRUCTIONS
When using an electrical appliance, basic safety precautions should always be followed,
including the following. Read all instructions before using this sewing machine.
DANGER – To reduce the risk of electric shock:
1. An appliance should never be left unattended when plugged in. Always unplug this appliance from the
electrical outlet immediately after using and before cleaning.
2. Always unplug before relamping. Replace bulb with same type rated 13.5 Vac, 3 Watts.
3. Do not reach for the appliance that has fallen into water. Unplug immediately.
4. Do not place or store appliance where it can fall or be pulled into a tub or sink. Do not place in or drop
into water or other liquid.
WARNING – To reduce the risk of burns, fire, electric shock, or injury to persons:
1. Do not allow to be used as a toy. Close attention is necessary when this appliance is used by or near
children.
2. Use this appliance only for its intended use as described in this manual. Use only attachments recom-
mended by the manufacturer as contained in this manual.
3. Never operate this appliance if it has a damaged cord or plug, if it is not working properly, if it has been
dropped or damaged, or dropped into water. Return the appliance to the nearest authorized dealer or
service center for examination, repair, electrical or mechanical adjustment.
4. Never operate the appliance with any air opening blocked. Keep ventilation openings of the sewing
machine and foot controller free from accumulation of lint, dust and loose cloth.
5. Never drop or insert any object into any opening.
6. Do not use outdoors.
7. Do not operate where aerosol (spray) products are being used or where oxygen is being administered.
8. To disconnect, turn all controls to the off position, then remove plug outlet.
9. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
10. Keep fingers away from all moving parts. Special care is required around the sewing machine needle
and knives.
11. Always use the proper needle plate. The wrong plate can cause the needle to break.
12. Do not use bent needles.
13. Do not pull or push fabric while stitching. It may deflect the needle causing it to break.
14. Switch the sewing machine off when making any adjustment in the needle area, such as threading
needle, changing needle, threading loopers, or changing presser foot, and the like.
15. Always unplug the sewing machine from the electrical outlet when removing covers, lubricating, or
when making any other user servicing adjustments mentioned in the instruction manual.
SAVE THESE INSTRUCTIONS
When using your overlock machine for the first few times, place some waste fabric under the presser
foot and run the machine without thread for a few minutes. Wipe away any oil which may have ap-
peared.

Controlling Sewing Speed
Sewing speed can be varied by the foot
control.The harder press on the foot control,
the faster the machine runs.
Note:
* The Compulock is equipped with a protective
circuit to prevent overheating.
The machine will stop automatically if it is
running overloaded for a long time.
In such a case, follow the message that
appears on the visual touch screen.
“ For appliances with a polarized plug (one blade
wider than the other).
To reduce the risk of electric shock, this plug is intended
to fit in a polarized outlet only oneway.
If the plug does not fit fully in the outlet, reverse the
plug.
If it still does not fit, contact a qualified electrician to
install the proper outlet.
Do not modify the plug in anyway.”

SECTION 2 OPERATING INSTRUCTIONS
For Your Safety
* While in operation, always keep your eye on
the sewing area,and do not touch any mov-
ing parts such as the upper looper, handwheel,
needle or knives.
* Always disconnect the machine from the
power supply:
When leaving the machine unattended.
When attaching or removing parts.
When threading or cleaning the machine.
* Do not place anything on the foot control,
except when in use.
There are five motors for thread tension ad-
justment inside the machine which make a bit
of noise intializing when first turned on.
This sound is perfectly normal and does not
indicate a malfunction.

Safety System
You can operate the machine easily and safely because of the following major safety functions.
The machine does not run when you pressed the foot control because...
1 The looper cover or side cover is opened when you start sewing.
2 Presser foot lifter is raised.
3 The needle plate is not appropriate for the chosen stitch pattern.
4 The upper looper setting dial is in the incorrect position for the chosen stitch pattern.
5 The upper knife is in the incorrect position for the chosen stitch pattern.
The above error messages will appear on the visual touch screen when you press the foot
control.
However, you can press OK key to ignore the warning and accept the upper knife position
(activated or deactivated). This may be appropriate for certain special stitches/operations.
A convenient threading chart is
placed the machine body inside
the looper cover.

1 Upper looper thread
2 Lower looper thread
3 Needle threads
If the machine becomes unthreaded, thread
the lower looper first, then the upper looper,
needle on the right and needle on the left.
* A convenient threading chart is placed the
machine body inside the looper cover.
When first threading the machine, or rethreading
after a break, please do the following:
1 Turn the handwheel toward you until the
needles are in the full up position, and pull
out about 10 cm (4”) of thread from the tip
of the upper looper.
2 Pull out 10 cm (4”) of thread from the tip of
the lower looper.
3 Pull out 10 cm (4”) of needle thread and
draw it toward the back of the machine
under the presser foot.
Now, lower the presser foot and sew.
Incorrect threading will cause skipped
stitches, broken thread or uneven thread
tension.
Before starting to sew, make sure that your
machine is threaded properly.
Turn off the power switch before threading the
machine.
The machine has been threaded at the factory
with short length of thread.
To thread the machine with your own thread,
tie it firmly to the upper end of the thread in the
machine, then raise the presser foot and pull the
other end.
For the needle threads, pull the bottom end of
thread until the knot comes to the needle eye,
and cut on both sides of the knot.

guides (4) and (5), as illustrated.
Holding the end of the thread, push the
lower looper thread guide (4) up with your
other hand to return it to its original position,
as illustrated.
Lower looper thread guides (4) and (5) will
return to their original position automatically
when you turn the handwheel toward you.
11 Move the lower looper to its rightmost
position by turning the handwheel, and
pass the thread through the hole in the lower
looper with the tweezers 10 cm (4") or more.
Make sure the needle threads are not
tangled in the lower looper and close the
looper cover.
* The illustration to the left demonstrates a
convenient way to thread the lower looper
with woolly nylon or polyester thread.
Use the same method with the upper looper.
