USER MANUAL LU1565N JUKI

ミシン操作中、釜は高速で回転しています。手への損傷防止のため、運転中は釜付近 へ絶対に手を近づけないでください。また、ボビン交換の時は電源を切ってください。 7.不意の起動による事故防止のため、電源の切り忘れに注意してください。 8.本製品は精密機器のため、水や油をかけたり、落下させるなどの衝撃を与えないよ うに、取扱いには十分注意してください。 9.ミシンを倒す時、また元の位置へ戻す時、指等をはさまないよう両手で頭部上側を 持ち、静かに行ってください。vi 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 speci¿cations of your product. The risk indications are classi¿ed 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. Warning label

1. To ensure safety, never operate the machine with the ground wire for the power

2. When inserting/removing the power plug, the power switch has to be turned OFF in

3. In time of thunder and lightening, stop your work and disconnect the power plug

from the receptacle so as to ensure safety.

4. If the machine is suddenly moved from a cold place to a warm place, dew

condensation may be observed. In this case, turn ON the power to the machine after you have confi rmed that there is no danger of water drops in the machine.

5. To prevent fi res, periodically draw out the power plug from the plug socket and

clean the root of the pins and the space between pins.

6. 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.

7. To avoid possible accidents due to abrupt start of the machine, be sure to turn OFF

the power to the machine.

8. Be careful of handling this product so as not to pour water or oil, shock by

dropping, and the like since this product is a precision instrument.

9. When tilting or returning the sewing machine to the home position, hold the upper

side of the machine head with both hands and perform the work quietly so that fi ngers or the like are not caught in the machine. CAUTION : Note that safety devices such as “eye guard”, “fi nger guard”, etc. may be omitted from the illustrations in this Instruction Manual for easy explanation. When operating the machine, be sure not to remove these safety devices.

1. Keep your hands away from needle when you turn ON the power switch or while

the machine is in operation.

2. Do not put your fi ngers into the thread take-up cover while the machine is

3. Turn OFF the power switch when tilting the machine head, or removing the belt

cover or the V belts.

4. During operation, be careful not to allow your or any other person’s head, hands

or clothes to come close to the handwheel, V belt and motor. Also, do not place anything close to them.

5. Do not operate your machine with the belt cover and fi nger guard removed.

6. When tilting the machine head, be sure to confi rm that the head support bar is

properly attached to your fi ngers or the like to be pinched in the machine head.xi ENGLISH DECLARATION OF INCORPORATION OF PARTLY COMPLETED MACHINERY We hereby declare that the sewing machine (sewing head) described below ;

• Before you put the machine into operation for the fi rst time after the set-up, clean it thoroughly . Remove all dust gathering during transportation and oil it well.

• Confi rm that voltage has been correctly set. Confi rm that the power plug has been properly connected to the power supply.

• Never use the machine in the state where the voltage type is different from the designated one.

• The direction of normal rotation of the machine is counterclockwise as observed from the pulley side. Take care not to allow the machine to rotate in the reverse direction.

• When tilting the machine head, tilt it after removing knee lifter hook.

• Never operate the machine unless the head base has been fi lled with oil.

• For a test run, remove the bobbin and the needle thread.

• For the fi rst month, decrease the sewing speed and run the sewing machine at a speed of 1,600 sti/min or less.

• Operate the handwheel after the machine has totally stopped. CAUTION : Check the following so as to prevent maloperation of and damage to the machine.– 2 –
