ESD
ATTENTION!
It is of the utmost importance that precautions are being taken in order to avoid damage of the electronics
by electro static discharges ESD (=Electro Static Discharge). To avoid that these errors arise it is important
to handle loose circuit boards in a controlled way.
Electrostatic charges are caused by:
• When a person is walking (influence) over synthetic tilled or carpeted floor
• When its friction between and separation of two insulating materials.
If this static electricity discharges through electronic components, these may be partially or irreparably
damaged. Electrostatically charged persons represent the greatest danger for components. This can be dissipated by controlled electrostatic discharge.
Always use wrist band when servicing.
Please note that on disposal, this product must be
safely recycled in accordance with relevant
National legislation relating to
electrical/electronic products. If in doubt please
contact your retailer for guidance.

Service tools
A reasonable requirement in a domestic sewing machine is that it should able to sew all types of fabrics
used in the home. The settings made when assembling and sewing-in the machines are those most suited
to
give the best results in the majority of fabrics and fabric combinations. In doing so, consideration has been
given to the requirements of different markets. This does, however, mean that when sewing extreme fabrics,
better results may be obtained in certain cases by altering the settings. It must be pointed out that these
altered settings can cause poorer results on more normal fabrics. How the different standard ratings are
set can be seen from the description under each setting instruction. The following list of setting gauges and
service tools is intended as an instruction about the special service tools needed to servicing this machine.
1. On several different occasions the needle is used as a setting gauge.
The setting ratings are adapted to needle 90. Make sure to use an undamaged needle.

the screw (1).
4. Turn on the main power and pinion gear will move so that screw (1) may be located upward and then
loosen screw (1). After above steps, the motor shaft will be excited so the shaft will not move and pinion
gear can be rotatable. Rotate pinion gear (A) again until it hits with stopper (B) then tighten screw (2) by

It is needed to fit the dial at same position as it was before taking it off.
Tighten screw with washer at the Thread tension wheel.
8. Attach sensor board (A) by two screws.
After attaching sensor, rotate dial clockwise and tip of dial must be crossed center of the sensor when dial
reaches not rotatable position (To insulate electric signal).
An error will occur when tip of dial is not crossed center of the sensor.

After entering the test mode 2 all the diffrent sensors of the machine is de-activated (Machine will run without thread).
Display No 102
Mode 2: Needle position at center without feed
Is used for checking the movement of the zig-zag step motor and centre position of the needle in straight
stitching. The zig-zag stepmotor calibrates and takes its Centre position.
Display No 103
Mode 3: Balance check
Machine will feed 2 mm, at center position, stitch 11 needles forward and backward.
Needle must always stop at the staring stitch

Mode 8: Adjusting the bobbin sensor sensitivity.
1. Prepare two thread wound bobbins.
Bobbin (A) should be wound with thread around 20 times and bobbin (B) should be wound with thread
around 10 times. Bobbin (B) is ideal for adjustment of bobbin thread sensor.
2. Place bobbin (A) into bobbin case and then press start button.
After starting the machine, check to see whether “00” will be displayed on LCD.
The situation of “00” means the sensitivity of the sensor is sp weak that the emitted light is cannot be
received.
3. Rotate trimmer either way to adjust sensitivity of the sensor while checking number displayed on LCD.
It is needed to be set very close to “01”, but not to “01” range. “00” should be displayed on LCD. This setting will not stop the machine with bobbin A.
4. Then replace bobbin (A) with bobbin (B).
5. Start the machine with bobbin (B) and check to see whether “01” will be displayed on LCD. If “00” or
“02” is displayed, go back to step (2) and readjust with bobbin (A).
6. The situation of “02” means the sensitivity of the sensor is so strong that the sensor will receive any
lights as a signal. So the machine will stop with bobbin (A) at the situation of “02”.
