4. INSTALLATION
4-"10. Lubrication
• Do not connect the power cord until lubrication has been completed, otherwise the machine may operate ifthe
treadle
is pressed by mistake, which could result in injury.
• Be sure to vvear protective goggles and gloves when handling the lubricating oil, so that no oil gets into your
eyes or onto your skin, otherwise inflammation can
result
Furthermore, do not drink the oil under any circumstances, as it can cause vomiting and diarrhoea.Keep the oil
out of the reach of children.
The sewing machine should always be lubricated and the oil supply replenished before it
is used for the first time, and also
after long periods of non-use.
Use only the lubricating oil.
• Add
1-2 drops of oil in the places indicated by the arrows.
Add oil to other sliding parts also, while being careful to avoid oil leaks.
Oiling must be done at least twice daily in continuous use.

1. Turn on the power switch.
2. Place the bobbinG:· onto the bobbin winder shaft
3. Wind the thread several times around the bobbin
<1· in
the direction indicated the arrow.
4. Push down the bobbin set lever Q).
5. Raise the presser foot with the presser bar lifter.
6. Depress the treadle. Lower thread winding will then
start.
7. Once .winding of the lower thread is completed, the
bobbin set
lever® will return automatically.
* If the thread cannot be wound on evenly, loosen the
screw@_~ and move the bobbin winder bracket to the
side where there
is less thread.
* Turn the adjustment screw @j to adjust the bobbin
winding amount.
To increase the winding amount: Tighten the screw.
To decrease the wincing amount: Loosen the screw.
Note:The amount of thread wound onto the bobbin
should
be a maximum of 80% of the bobbin
capacity.
• Turn off the power supply before installing the bobbin case. The motor will keep turning even after the power is
switched off as a result of the motor's inertia. Wait until the motor stops fully before starting work. The
machine may operate if the treadle
is pressed by mistake, which could result in injury.
1. While holding the bobbin so that the thread winds to
the right, insert the bobbin into the bobbin case.
2. Pass the thread through the slot and under the
tension spring
\21.
3. Pull the thread cut through the hole in the end of the
tension spring
(2:.
4. Check that the bobbin turns clockwise when the thread
is pulled.
5. Hold the latch ;.3; on the bobbin case and insert the
bobbin case into the rotary hook.
6. Close the bed slide.

5-5. Threading the upper thread
CAUTION
• Turn off the power supply before installing the bobbin case. The motor will keep turning even after the power is
switched off as a result of the motor's inertia. Wait until the motor stops fully before starting work. The
machine may operate if the treadle is pressed by mistake, which could result in injury.
5-6. Adjusting the stitch length

Turn the machine pulley and raise the thread take up lever
G:· before threading the upper thread. This will make
threading easier
and it will prevent the thread from coming
out
at the sewing start.
Stitch length can be set by turning the feed regulating dial
Ci·.
Numeric figures on the dial i.l' show the stitch length in
mm. The desired numeric figure on the dial should be
set at just above, while depressing the revers lever
slightly.
