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.
(III) Grounding
1. Be sure to have an electrical expert install an appropriate power plug in order to prevent accident caused
by earth-leakage or dielectric strength voltage fault. In addition, be sure to connect the power plug to the
grounded outlet without exceptions.
2. Be sure to ground the earth cable in order to prevent accident caused by earth leakage.
(IV) Motor
1. Be sure to use the specified rated motor (JUKI genuine product) in order to prevent accident caused by
burnout.
2. If a commercially available clutch motor is used with the machine, be sure to select one with an entan-
glement preventive pulley cover in order to protect against being entangled by the V-belt.
Before operation
1. Be sure to make sure that the connectors and cables are free from damage, dropout and looseness be-
fore turning the power on in order to prevent accident resulting in personal injury or death.
2. Never put your hand into the moving sections of the machine in order to prevent accident that can result
in personal injury or death.
In addition, check to be sure that the direction of rotation of the pulley agrees with the arrow shown on
pulley.
3. If the table stand with casters is used, be sure to secure the table stand by locking the casters or with
adjusters, if provided, in order to protect against accident caused by abrupt start of the machine.
During operation
1. Be sure not to put your fingers, hair or clothing close to the moving sections such as the handwheel,
hand pulley and motor or place something near those sections while the machine is in operation in order
to prevent accident caused by entanglement that can result in personal injury or death.
2. Be sure not to place your fingers near the surround area of the needle or inside the thread take-up lever
cover when turning the power on or while the machine is in operation in order to prevent accident that
can result in personal injury or death.
3. The machine runs at a high speed. Never bring your hands near the moving sections such as looper,
spreader, needle bar, hook and cloth trimming knife during operation in order to protect your hands
against injury. In addition, be sure to turn the power off and check to be sure that the machine complete-
ly stops before changing the thread.
4. Be careful not to allow your fingers or any other parts of your body to be caught between the machine
and table when removing the machine from or replacing it on the table in order to prevent accident that
can result in personal injury or death.
iv
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.
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.

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 5°C to 35°C
