TO ENSURE SAFE USE OF YOUR SEWING MACHINE 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.

2. The content of this section includes items which are not contained in the specifications of your product. 3. Be sure to wear safety goggles to protect against accident caused by needle breakage. 4. Those who use a heart pacer have to use the machine after consultation with a medical specialist. Safety devices and warning labels 1. Be sure to operate the machine after verifying that safety device(s) is correctly installed in place and works normally in order to prevent accident caused by lack of the device(s). 2. If any of the safety devices is removed, be sure to replace it and verify that it works normally in order to prevent accident that can result in personal injury or death. 3. Be sure to keep the warning labels adhered on the machine clearly visible in order to prevent accident that can result in personal injury or death. If any of the labels has stained or come unstuck, be sure to change it with a new one. Application and modification 1. Never use the machine for any application other than its intended one and in any manner other than that prescribed in the instruction manual in order to prevent accident that can result in personal injury or death. JUKI assumes no responsibility for damages or personal injury or death resulting from the use of the machine for any application other than the intended one. 2. Never modify and alter the machine in order to prevent accident that can result in personal injury or death. JUKI assumes no responsibility for damages or personal injury or death resulting from the ma- chine which has been modified or altered. Education and training 1. In order to prevent accident resulting from unfamiliarity with the machine, the machine has to be used only by the operator who has been trained/educated by the employer with respect to the machine oper- ation and how to operate the machine with safety to acquire adequate knowledge and operation skill. To ensure the above, the employer has to establish an education/training plan for the operators and edu- cate/train them beforehand. Items for which the power to the machine has to be turned off Turning the power off: Turning the power switch off, then removing the power plug from the outlet. This applies to the following. 1. Be sure to immediately turn the power off if any abnormality or failure is found or in the case of power failure in order to protect against accident that can result in personal injury or death.

Transportation 1. Be sure to lift and move the machine in a safe manner taking the machine weight in consideration. Refer to the text of the instruction manual for the mass of the machine. 2. Be sure to take sufficient safety measures to prevent falling or dropping before lifting or moving the machine in order to protect against accident that can result in personal injury or death. 3. Once the machine has been unpacked, never re-pack it for transportation to protect the machine against breakage resulting from unexpected accident or dropping. Unpacking 1. Be sure to unpack the machine in the prescribed order in order to prevent accident that can result in personal injury or death. In the case the machine is crated, in particular, be sure to carefully check nails. The nails have to be removed. 2. Be sure to check the machine for the position of its center of gravity and take it out from the package carefully in order to prevent accident that can result in personal injury or death. Installation (I) Table and table stand 1. Be sure to use JUKI genuine table and table stand in order to prevent accident that can result in per- sonal injury or death. If it is inevitable to use a table and table stand which are not JUKI genuine ones, select the table and table stand which are able to support the machine weight and reaction force during operation. 2. If casters are fitted to the table stand, be sure to use the casters with a locking mechanism and lock them to secure the machine during the operation, maintenance, inspection and repair in order to prevent accident that can result in personal injury or death. (II) Cable and wiring 1. Be sure to prevent an extra force from being applied to the cable during the use in order to prevent electrical-shock, earth-leakage or fire accident. In addition, if it is necessary to cable near the operating section such as the V-belt, be sure to provide a space of 30 mm or more between the operating section and the cable. 2. Be sure to avoid starburst connection in order to prevent electrical-shock, earth-leakage or fire accident. 3. Be sure to securely connect the connectors in order to prevent electrical-shock, earth-leakage or fire accident. In addition, be sure to remove the connector while holding its connector section.

5. Be sure to turn the power off and check to be sure that the machine and motor completely stop before re- moving the belt cover and V-belt in order to prevent accident caused by abrupt start of the machine or motor. 6. If a servomotor is used with the machine, the motor does not produce noise while the machine is at rest. Be sure not to forget to turn the power off in order to prevent accident caused by abrupt start of the motor. 7. Never use the machine with the cooling opening of the motor power box shielded in order to prevent fire accident by overheat. Lubrication 1. Be sure to use JUKI genuine oil and JUKI genuine grease to the parts to be lubricated. 2. If the oil adheres on your eye or body, be sure to immediately wash it off in order to prevent inflamma- tion or irritation. 3. If the oil is swallowed unintentionally, be sure to immediately consult a medical doctor in order to pre- vent diarrhea or vomiting. Maintenance 1. In prevention of accident caused by unfamiliarity with the machine, repair and adjustment has to be carried out by a service technician who is thoroughly familiar with the machine within the scope defined in the instruction manual. Be sure to use JUKI genuine parts when replacing any of the machine parts. JUKI assumes no responsibility for any accident caused by improper repair or adjustment or the use of any part other than JUKI genuine one. 2. In prevention of accident caused by unfamiliarity with the machine or electrical-shock accident, be sure to ask an electrical technician of your company or JUKI or distributor in your area for repair and mainte- nance (including wiring) of electrical components. 3. When carrying out repair or maintenance of the machine which uses air-driven parts such as an air cyl- inder, be sure to remove the air supply pipe to expel air remaining in the machine beforehand, in order to prevent accident caused by abrupt start of the air-driven parts. 4. Be sure to check that screws and nuts are free from looseness after completion of repair, adjustment and part replacement. 5. Be sure to periodically clean up the machine during its duration of use. Be sure to turn the power off and verify that the machine and motor stop completely before cleaning the machine in order to prevent accident caused by abrupt start of the machine or motor.

To avoid possible personal injury due to abrupt start of the machine, turn off the power to the machine and check to be sure that the motor has totally stopped rotating in prior. Oil sight window HIGH mark LOW mark Oil reservoir 1. Before operation, fill the oil reservoir with JUKI New Defrix Oil No.1 up to the HIGH mark. 2. Whenever the oil level drops to the LOW mark, add more oil. 3. When the sewing machine is run after the oil reservoir has been filled, oil can be seen splashing on the oil sight window. However, the amount of oil splash has no relation to the amount of oil in the reservoir so there is no need to worry. 4. When the oil has become dirty, replace it with fresh oil. Unscrew the oil plug from the oil reservoir when draining. 5. When using a new sewing machine or one that has not been used for a long time let it idle for about ten minutes at 3,000 to 3,500 sti/min to run it in.
