CAUTIONS FOR SAFETY
i
i
For the sewing machine, automatic machine and ancillary devices (hereinafter collectively referred to as
"machine"), it is inevitable to conduct sewing work near moving parts of the machine. This means that there
is always a possibility of unintentionally coming in contact with the moving parts. Operators who actually
operate the machine and maintenance personnel who are involved in maintenance and repair of the machine
are strongly recommended to carefully read to fully understand the following SAFETY PRECAUTIONS
before using/maintaining the machine. The content of the SAFETY PRECAUTIONS includes items which
are not contained in the specications of your product.
The risk indications are classied into the following three different categories to help understand the meaning
of the labels. Be sure to fully understand the following description and strictly observe the instructions.

machine tree from the accumulation of lint, dust, and loose cloth.
2. Keep ngers away from all moving parts. Special care is required aroung the sewing machine needle.
3. Always use the proper needle plate. The wrong plate can cause the needle to break.
4. Do not use bent needles.
5. Do not pull or push fabric while stitching. It may deect the needle causing it to break.
6. Switch the sewing machine off when making any adjustments in the needle area, such as threading
needle, changing needle, threading bobbin, or changing presser foot, and the like.
7. Always disconnect power source from sewing machine when removing covers, Iubricating, or when
making any other user servicing adjustments mentioned in the Instruction manual.
8. Keep your hands away from the needle when you turn the power switch ON or while the machine is
operating.
9. Do not put your ngers into the thread take-up cover while the machine is operating.
10. Be sure to turn the power switch OFF before tilting the machine head or removing the V belt.
11. While the sewing machine is in operation, be careful not to allow your or any other person’s head or

to them. Doing so may be dangerous.
12. If your machine is provided with a belt cover, nger guard or any other protectors, do not operate your
machine with any of them removed.
13. To achieve security, be sure that the power supply earth wire has been connected before operating the
sewing machine.
14. No motor sound is heard when the sewing machine is not operating. So, do not forget to turn the power
OFF at the end of work.
15. When you move the unit from a cold place directly to a warm place, dew condensation may result. Turn

Precautions to be taken so as to use the DDL-8700B-7
more safely
CAUTION BEFORE OPERATION
• Clean the sewing machine thoroughly before using it for the rst time.
• Remove all dust collected on the sewing machine during the transportation.
• Conrm that the voltage and phase are correct.
• Conrm that the power plug is properly connected.
• Never use the sewing machine in the state where the voltage type is different from the
designated one.
• The direction of rotation of the sewing machine is counterclockwise as observed from the
handwheel side. Be careful not to rotate it in reverse direction.
WARNING :
To avoid malfunction and damage of the machine, conrm the following.
1. Neither open the pulley cover nor touch the parts inside the pulley cover with the
power remained on in order to prevent accidents due to electrical shock.
1. Do not operate the sewing machine with the pulley cover and the nger guard
removed in order to protect against personal injury.
2. Neither place ngers, hair and/or clothes nor put anything in the area near the
thread take-up lever while the sewing machine is in operation in order to protect
against personal injury due to entanglement.
3. Keep ngers away from the thread take-up cover and the needle when turning the
power on in order to protect ngers and hands against injury.
4. To avoid personal injury, be careful not to allow your ngers in the machine when

5. The hook rotates at a high speed while the machine is in operation. To prevent
possible injury to hands, be sure to keep your hands away from the vicinity of the
hook during operation. In addition, be sure to turn OFF the power to the machine
when replacing the bobbin.
6. So as to avoid personal injuries caused by abrupt start of the machine, turn OFF
the power switch and ascertain that the sewing machine does not run even if
the starting pedal is depressed when performing such works as inspection or
adjustment of the sewing machine, cleaning, threading, replacing the needle, etc.
7. So as to avoid electrical shock hazards, do not operate the machine with the power
supply earth wire removed.
8. So as to avoid electrical shock hazards and accidents caused by damaged
electrical components, be sure to turn OFF the power switch before inserting/
detaching the power plug.
9. So as to avoid personal injuries caused by abrupt start of the machine, turn OFF
the power switch when leaving the sewing machine table.
10. So as to avoid personal injuries caused by abrupt start of the machine, turn OFF
the power switch when the electricity fails.
11. To prevent res, periodically draw out the power plug from the plug socket and
clean the root of the pins and the space between pins.
12. The motor does not produce noise while the machine is at rest. To avoid possible
accidents due to abrupt start of the machine, be sure to turn OFF the power to the
machine.
13. Be careful of handling this product so as not to pour water or oil, shock by
