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 car-
ried out by a service technician who is thoroughly familiar with the machine within the scope defined in
the engineer's 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 ac-
cident caused by abrupt start of the machine or motor.
6. Be sure to turn the power off and verify that the machine and motor stop completely before carrying out
maintenance, inspection or repair of the machine. (For the machine with a clutch motor, the motor will
keep running for a while by inertia even after turning the power off. So, be careful.)
7. If the machine cannot be normally operated after repair or adjustment, immediately stop operation and
contact JUKI or the distributor in your area for repair in order to prevent accident that can result in per-
sonal injury or death.
8. If the fuse has blown, be sure to turn the power off and eliminate the cause of blowing of the fuse and
replace the blown fuse with a new one in order to prevent accident that can result in personal injury or
death.
9. Be sure to periodically clean up the air vent of the fan and inspect the area around the wiring in order to
prevent fire accident of the motor.
10. In order to prevent accidents resulting in personal injury or death, adjustments have to be carried out
within the instructions described in this Engineer's Manual and in the Instruction Manual by the person-
nel who have been well trained by the employer with respect to the latest knowledge and safety for the
machine.
11. Make sure that water is contained in cylinders and pipes, then remove water from them in order to pre-
vent accidents due to a malfunction of the machine.
�perating environment
1. Be sure to use the machine under the environment which is not affected by strong noise source (electro-
magnetic waves) such as a high-frequency welder in order to prevent accident caused by malfunction of
the machine.
2. Never operate the machine in any place where the voltage fluctuates by more than "rated voltage ±10 %"
in order to prevent accident caused by malfunction of the machine.
3. Be sure to verify that the air-driven device such as an air cylinder operates at the specified air pressure
before using it in order to prevent accident caused by malfunction of the machine.
4. To use the machine with safety, be sure to use it under the environment which satisfies the following
conditions:
Ambient temperature during operation
Relative humidity during operation
5. Dew condensation can occur if bringing the machine suddenly from a cold environment to a warm one.
So, be sure to turn the power on after having waited for a sufficient period of time until there is no sign
of water droplet in order to prevent accident caused by breakage or malfunction of the electrical compo-
nents.
6. Be sure to stop operation when lightning flashes for the sake of safety and remove the power plug in
order to prevent accident caused by breakage or malfunction of the electrical components.
7. Depending on the radio wave signal condition, the machine may generate noise in the TV or radio. If this
occurs, use the TV or radio with kept well away from the machine.
8. In order to ensure the work environment, local laws and regulations in the country where the sewing
machine is installed shall be followed.
In the case the noise control is necessary, an ear protector or other protective gear should be worn ac-
cording to the applicable laws and regulations.
9. Disposal of products and packages and treatment of used lubricating oil should be carried out properly
according to the relevant laws of the country in which the sewing machine is used.
