“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. The appliance should never be left unattended when plugged in.
2.
Always unplug this appliance from the electric outlet immediately after using and before cleaning.
“WARNING ____ To reduce the risk of burns, re, electric shock, or injury to persons:”
1. Do not use the appliance as a toy. Caution is advised when the appliance is used by children, or
near children. This sewing machine can be used by children aged from 8 years and above and
persons with reduced physical, sensory or mental capabilities or lack of experience and knowl-
edge if they have been given supervision or instruction concerning use of the sewing machine
in a safe way and understand the hazards involved. Children shall not play with the sewing ma-
chine. Cleaning and user maintenance shall not be made by children without supervision.
2. Use this appliance only for its intended use as described in this manual. Use only attachments
recommended 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 au-
thorized dealer or service center for examination, repair, electrical or mechanical adjustment.
4. Never operate the appliance with any air openings blocked. Keep ventilation openings of the
sewing machine and foot control free from the accumulation of lint, dust, and loose cloth.
5.
Keep ngers away from all moving parts. Special care is required around the sewing machine needle.
6. Always use the proper stitch plate. The wrong plate can cause the needle to break.
7. Do not use bent needles.
8. Do not pull or push fabric while stitching. It may deect the needle causing it to break.
9. Do not carry out sewing with a marking pin stuck in the material since doing so can cause knife/
needle breakage. In addition, do not attempt to cut anything other than fabric and thread with
the upper/lower knives.
10. Switch the sewing machine off “O” when making any adjustments in the needle area, such as
threading needle, changing needle, threading looper, or changing presser foot and the like.
11. Always unplug the machine from the electrical outlet when removing covers, when covers are
opened to thread the loopers, when lubricating or when making any other user servicing adjust-
ments mentioned in the instruction manual.
12. Never drop or insert any object into any opening.
13. Do not use outdoors.
14.
Do not operate where aerosol (spray) products are being used or where oxygen is being administered.
15. To disconnect, turn all controls to the off “O” position, then remove plug from outlet.
16. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
17. Basically, the machine should be disconnected from the electricity supply when not in use.
18. If the power cord of this appliance is damaged, it must be replaced with a special cord by your
nearest authorized dealer or service center.
19. (Except USA/Canada) This machine is provided with double insulation.
Use only identical replacement parts. See instructions for servicing Double-Insulated machine.
“SERVICING DOUBLE-INSULATED PRODUCTS
(Except USA / Canada)”
In a double-insulated product, two systems of insulation are provided instead of grounding. No
grounding means is provided on a double-insulated product nor should a means for grounding be
added to the product. Servicing a double-insulated product requires extreme care and knowledge
of the system and should only be done by qualied service personnel. Replacement parts for a
double-insulated product must be identical to those parts in the product. A double-insulated product
is marked with the words DOUBLE INSULATION or DOUBLE INSULATED.
The symbol may also be marked on the product.

To use the sewing machine safely
Marks and pictographs included in the Instruction Manual and shown on the sewing machine are
used so as to ensure safe operation of the sewing machine and to prevent possible risk of injury to
the user and other people.
Warning marks are used for different purposes as described below.
WARNING Indicates that there is a possible risk of death or serious injury if this mark is
ignored and the sewing machine is used in a wrong manner.
CAUTION
Indicates the operation, etc. which can cause a possible risk of personal injury
and/or physical damage if this mark is ignored and the sewing machine is used in
a wrong manner.
Pictographs mean the following:
2
● Do not wipe the sewing machine with solvent
such as thinner.
When the sewing
machine is soiled, put a
small quantity of neutral
detergent on a piece of
soft cloth and carefully
wipe off the sewing
machine with it.
● Be sure to use the sewing machine in the
temperature range from 5ºC to 40ºC.
If the temperature is excessively low, the
machine can fail to operate normally.
WARNING
For the combination of the material and the thread and needle, in particular, refer to the explanation
table in “Replacement of the needle”.
If the needle or thread does not match the material used such as in the case that an extra heavy-
weight material (e.g., denim) is sewn with a thin needle (#11 or higher), the needle can break result-
ing in an unexpected personal injury.
Other precautions
● Do not put the sewing machine under the
direct sunlight or in a humid place.
Be aware that the following state can take place since the sewing machine incorporates semi-con-
ductor electronic parts and precise electronic circuits.
* The operating temperature of the sewing machine is between 5ºC and 40ºC. Do not use the
sewing machine under the direct sunlight, near the burning things such as a stove and candle, or
in a humid place. By so doing, the temperature in the interior portion of the sewing machine can
rise or the coating of the power cord can melt, causing re or electrical shock.

Preparing the machine
Attaching the foot control
Plug foot control into the machine socket (A) and then into the main
socket (B). The foot control regulates the sewing speed. The sewing
speed can be adjusted by increasing or decreasing the pressure on
the foot control.
“WARNING”
This appliance has a polarized plug (for USA and Canada only, one
blade wider than the other).
To reduce the risk of electric shock, this plug is intended to t in a
polarized main socket only one way.
If the plug does not t fully in the polarized main socket, reverse the
plug. If it still does not t, contact a qualied electrician to install the
proper polarized main socket. Do not modify the plug in any way. (for
USA, Canada only)
* Use only the foot control model YC-482 (USA, Canada), YC-483N
(220-240V).
Thread stand
Push the support rod rmly into the socket on the back of the ma-
chine. Raise the support rod (C) fully, turning slightly until the po-
sition catches engage. Position the thread guide (D) on the thread
stand so that the arrow is to the front.
Polarized plug
(for USA, Canada only)
Polarized main socket

Thread / cones / spools
The anti-vibration cone should
be used with the wider edge at
the bottom on the spool holder
pin when sewing with cones.
Large spools
If large industrial spools are used,
position the anti-vibration cone up-
side down on the spool holder pin,
i.e. with the wider edge at the top.
Household spools
Remove the anti-vibration
cones. Place spools on spool
holder pins and push the spool
caps on with the rounded side
downwards.
Thread nets
If the threads slip and gets twist-
ed, cover the spools of upper and
lower looper with the nets supplied
in the accessory bag.
Using the machine
Power/light switch
The power/light switch is conveniently placed on the handwheel side of
the machine in front of the socket.
O = Off
I = On with light
Two step presser foot
To raise the presser foot, lift the presser foot lever on the rear of the
machine, until it engages (A). It can be raised again to the maximum
height and held in this position to provide more space between presser
foot and stitch plate.(B).
Note: When the presser foot is raised, all the tensions are released
making it easier to thread the machine.
