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 heavyweight material (e.g., denim) is sewn with a thin needle (#11 or higher), the needle can break resulting in an unexpected personal injury.
Other precautions
●Do not put the sewing machine under the direct sunlight or in a humid place.
●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 aware that the following state can take place since the sewing machine incorporates semi-conductor electronic parts and precise electronic circuits.
●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.
●The safety device of the sewing machine will work to stop the sewing machine in order to prevent the generation of abnormal heat in the case the sewing machine is continuously engaged in sewing at a low sewing speed for a long time or it is continuously engaged in sewing for a long time under the high temperature environment. In this event, Start and Stop button will not light.
The sewing machine will Stop! return to working condition
after about 10 minutes.
*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 fire or electrical shock.

Function of operational buttons
Needle up/down button
When machine stops, press this button to change the needle position. (When the needle is up, the needle moves down and vise versa.)
The sewing machine performs sewing at a low speed by keeping this button held pressed for a long time.
*The needle will not move when the presser foot is in its upper position or no pattern is selected.
Presser foot auto lift button
When this button is pressed while the sewing machine is at rest, the presser foot position is changed.
When the presser foot is in its upper position, it comes down to its lower position and vice versa.
Thread trimming button
After sewing, press this button to trim both threads automatically.
Speed controller
While sewing, speed can be adjusted.
Lock stitch button
When this button is pressed, the sewing machine performs lock stitch.
When this button is pressed while the sewing machine is engaged in pattern sewing, the sewing machine stops after it has completed the sewing of the one-cycle/one-point of the pattern.
Reverse stitch button
For straight stitch/zigzag stitch: The sewing machine performs reverse stitch as long as this button is held pressed.
For other stitch types: The sewing machine performs lock stitch.
Start/stop button
When pressing this button, machine starts to sew slowly and then up to the speed set by speed controller. Another press of this button stops the sewing machine.
Color of button indicates machine status.
Green: Ready to start and/or while sewing
Red: Not ready to start
Orange: When the lock stitch button is pressed while the sewing machine is engaged in pattern sewing (The sewing machine performs lock stitch after it has completed the sewing of the pattern by one cycle. Then, the sewing machine stops.)
Notes for thread trimming:
1.Do not use thread thicker than No.30.
2.After trimming, the stitch can be done without pulling up bobbin thread.
3.When sewing again after thread trimming, if you pull up the bobbin thread again and place it underneath the presser foot together with needle thread, you can avoid birds nest on the wrong side of the fabric.
4.Regularly clean the machine (refer to page 111), as dust in the area of the thread trimming unit may cause malfunction.

*Thin thread and needle will be used for light-weight fabrics and thick thread and needle will be used for heavyweight materials.
*Check that the combination of needle and thread is OK by trial sewing on the material which will be sewn.
* Knit needle is good for stretchy fabrics (such as knits) and synthetic fabrics. * Use thread No. 30 - 90.
*When it is difficult to go over an overlapped section, guide the fabric by hand.
*When sewing “quilt patterns”, “decorative patterns” or “letters” (refer to pages 31 to 36), better finish will be ensured by using a knit needle.

Bobbin thread
Well-balanced thread tension
Straight stitch: Needle and bobbin threads interlace with each other at the middle of the fabric thickness. ( A )
Zigzag stitch: Needle thread is pulled a little bit to the wrong side of the fabric.
If the machine is set to “Auto”, it is suitable for most fabrics. However, adjustment may be necessary according to fabrics and sewing applications.
If the tension is not correctly set, it will cause imbalanced stitch formation, puckering, and/or thread breakage.

When the needle thread is too strong:
The bobbin thread will be pulled to the front side of the fabric. Turn the thread tension adjustment dial towards
"-1" to "-3".
When the needle thread is too low:
The needle thread will be pulled to the wrong side of fabric. Turn the thread tension adjustment dial towards
"+1" to "+3".
In case a correct tension setting is not obtained, check thread paths for both needle and bobbin threads.
