safe operation of this machine and to prevent accidents and injury to yourself or other people.
The meaning of these indications and symbols are given below.
Indications
DANGER
CAUTION
The instructions which follow this term indicate situations where failure to follow the
instructions will almost certainly result in death or severe injury.
The instructions which follow this term indicate situations where failure to follow the
instructions could cause injury when using the machine or physical damage to equipment
and surroundings.
Symbols
This symbol (△) indicates something that you should be careful of. The picture inside the
triangle indicates the nature of the caution that must be taken.
(For example, the symbol at left means"beware of injury".)
This symbol (○) indicates something that you must not do.

危险
打开控制箱盖时，必须先关闭电源开关并将电源插头从插座上拔下，至少等待5分钟后，再打开控
制箱盖。触摸带有高电压的区域将会造成人员伤亡。
注意
使用环境
应避免在强电气干扰源(如高频焊机)的附近使
用缝纫机。
强电气干扰源可能会影响缝纫机的正确操作。
电源电压的波动应该在额定电压的±10%以内
的环境下使用。
电压大幅度的波动会影响缝纫机的正确操作。
电源容量应大于缝纫机的消耗能量。电源容
量不足会影响缝纫机的正确操作。
环境温度应在5℃-35 的范围内使用。
低温或高温会影响缝纫机的正确操作。
℃
缝纫机的最佳工作环境是
85%的范围内，干燥或潮湿的环境均会影响缝
纫机的正确操作。
相对湿度在45%-
使用时应避免暴露于直射的阳光下。
直射的阳光会影响缝纫机的正确操作。
万一发生雷电暴风雨时，关闭电源开关，并将
电源插头从插座上拔下。雷电可能会影响缝纫
机的正确操作。
安装
请让受过培训的技术人员来安装缝纫机。
请委托购买商店或电气专业人员进行电气
配线。
缝纫机重约40公斤，安装工作必须由两人以
上来完成。
在安装完成前，请不要连接电源，如果误
按启动开关，缝纫机动作会导致受伤。
请在切断电源后，再拔掉电源插头。不然易
成为控制箱发生故障的原因。
必须接地。接地线不牢固，是造成触电
或误动作的原因。
固定电缆时，不要过度弯曲电缆或用卡钉
固定得过紧，会引起火灾或触电的危险。
如果使用带小脚轮的工作台，则应该固定小
脚轮，使其不能移动。
缝纫机头倒下或竖起时，请用双手进行操
作。单手操作时因缝纫机的重量万一滑落易
导致受伤。
使用润滑油或黄油时，务必戴好保护眼镜和
保护手套等，以防润滑油落入眼中或沾在皮
肤上，这是引起发炎的原因。
另外，润滑油或黄油不能饮用，否则会引起
呕吐和腹泻。
将油放在小孩拿不到的地方。

DANGER
Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall outlet before
opening the face plate of the control box. Touching areas where high voltages are present can result in severe injury.
CAUTION
Environmental requirements
Use the sewing machine in an area which is free from
sources of strong electrical noise such as high-
frequency welders.
Sources of strong electrical noise may cause
problems with correct operation.
Any fluctuations in the power supply voltages should
be within ±10% of the rated voltage for the machine.
Voltage fluctuations which are greater than this may
cause problems with correct operation.
The power supply capacity should be greater than
the requirements for the sewing machine's electrical
consumption.
Insufficient power supply capacity may cause
problems with correct operation. In the event of an electrical storm, turn off the power
and disconnect the power cord from the wall outlet.
Lightning may cause problems with correct operation.
The ambient temperature should be within the range
of 5℃ to 35℃ during use.
Temperatures which are lower or higher than this may
cause problems with correct operation.
The relative humidity should be within the range of
45% to 85% during use, and no dew formation should
occur in any devices.
Excessively dry or humid environments and dew
formation may cause problems with correct operation.
Avoid exposure to direct sunlight during use.
Exposure to direct sunlight may cause problems with
correct operation.
Installation
Machine installation should only be carried out
by a qualified technician.
Contact your dealer or a qualified electrician for
any electrical work that may need to be done.
The sewing machine weighs approximately 40kg.
The installation should be carried out by two or
more people.
Don't connect the power cord until installation is
complete, otherwise the machine may operate if
the foot switch is depressed by mistake, which
could result in injury.
Be sure to connect the ground. If the ground
connection is not secure, you run a high risk of
receiving a serious electric shock, and problems
with correct operation may also occur.
Install the safety covers to the machine head and
motor.
Hold the machine head with both hands when tilting
it back or returning it to its original position.
Furthermore, after tilting back the machine head,
do not push the face plate side or the pulley side
from above, as this could cause the machine head
to topple over, which may result in personal injury
or damage to the machine.
All cords should be secured at least 25mm away
from any moving parts. Furthermore, do not
excessively bend the cords or secure them too
firmly with staples, otherwise there is the danger
that fire or electric shocks could occur.
If using a work table which has caster, the
casters should be secured in such a way so that
they cannot move.
Be sure to wear protective goggles and gloves
when handling the lubricating oil and grease, so
that they don't get into your eyes or onto your
skin, otherwise inflammation can result.
Furthermore, do not drink the oil or eat the
grease under any circumstances, as they can
cause vomiting and diarrhoea.
Keep the oil out of the reach children.

1.The pedal is operated in the following four steps.
1) The machine runs at low sewing speed when you lightly depress the from part of the pedal .
2) The machine runs at high sewing speed when you further depress the front part of the pedal . (If the automatic reverse feed
stitching has been preset, the machine runs at high speed after it completes reverse feed stitching.)
3) The machine stops (with its needle up or down) when you reset the pedal to its original position .
4) The machine trims threads when you fully depress the back part of the pedal.
·If your machine is provided with the Auto-lifter (AK Series). An addition step is given between the machine stop and thread
trimming step.
The presser foot goes up when you lightly depress the back part of the pedal, and if you further depress the back part, the
thread trimmer is actuated.
·If you reset the pedal to its neutral position during the automatic reverse feed stitching at seam start, the machine stops after
it completes the reverse feed stitching.
·The machine will perform normal thread trimming even if you depress the back part of the pedal immediately following high
or low speed sewing.
·The machine will completely perform thread trimming even if you reset the pedal to its neutral position immediately after the
machine started thread trimming action.
·When the machine stops with its needle down, and if you want to bring the needle up, depress the back part of the pedal
once.

If you run the machine putting the solenoid in the
operation mode, the movable knife ① will rotate by the
thread trimming cam. The standard will be where the cut
part of the movable knife ① progresses1.0 to1.5mm from
the end edge of the fixed blade ② when the progress
amount of the movable knife is in its maximum.
(3) Adjusting blade pressure
A. As in Figure , the standard is when the contact between
the movable knife and the fixed blade begins.
B. In particular, when the cutting quality gets worse by
using a thick thread, strengthen a little bit the tension of
the fixed blade.
