SAFETY INSTRUCTIONS
3.3 Installation, preparation
3.3.1 Machine table
Prepare a machine table (table board and legs) that
has sufficient strength to withstand the weight of the
sewing head and any reaction while operating.
Securely join the table and legs to ensure sufficient
strength to withstand the weight of the sewing head
and any reaction while operating.
○ Maintain a comfortable working environment with
consideration of the lighting and the arrangement
of sewing machine to enable the operators to work
smoothly.
○ Adjust the height of the table according to the posture
of the worker.
Also, when installing the control box and the related
parts on the sewing machine, make sure not to affect
the posture of the worker. If casters are fitted to the
table stand, be sure to use high-strength casters with
a locking mechanism.
Lock the casters except when moving the machine.
3.3.2 Wiring and grounding
Never connect the plug for power supply until assembly
is finished.
Also, be sure to avoid the usage of multiple-outlet
extension cords in order to prevent electrical shock,
earth-leakage or fire accident.
Fix the connectors securely to the sewing machine
head, motor, and electric apparatus.
Also, when unplugging the connectors, hold the
connector part.
When wiring the connection cords, please take care of
the following.
○ Connect the cords away from the driving parts.
○ Do not apply excessive force to the connection cords.
○ Do not bend the cords excessively.
Never use staples to fasten the cables. Otherwise it may
cause a short circuit and/or fire.
Arrange the ground wire securely to the designated position
on the machine head.
Also, wire separately from the grounding for other
equipment.
iv
3.3.3 Handling machine oil
Keep machine oil out of the reach of children.
Be sure to fill or add lubrication oil to sewing machines
before operating them.
Use "Yamato SF oil 28" as specified.
If machine oil gets in your eyes, it may cause eye
inflammation. Always wear protective glasses to
prevent the oil from getting in your eyes.
*Should machine oil get in your eyes, wash them with
fresh water for 15 minutes and then consult a medical
doctor.
If oil adheres to your eyes or body, be sure to
immediately wash it off in order to prevent inflammation
or irritation.
If oil is swallowed unintentionally, be sure to consult a
medical doctor in order to prevent diarrhea or vomiting.
Methods of disposing of waste oil and/or containers
are specified by law. Dispose of it properly as required
by law. If you have further questions on its disposal,
consult the place of purchase.
After opening the oil container, be sure to seal it to
prevent dust and water from getting into the oil and
keep it in the dark to avoid direct sunlight.
Do not store in high-temperature areas or areas
exposed to an open flame.
WARNING
3.4 Before operation
○ Never put your hand under the needle or near the
moving parts of the machine when turning on the power
supply switch.
○ When operating a new sewing machine, make sure
the rotating direction of the pulley agrees with the
rotating-direction mark.
○ Before turning the power on, visually check the
cables and connectors for conditions such as damage,
disconnection and/or loosening.
○ If a table stand with casters is used, be sure to secure
the table stand by locking the casters or securing the
legs with adjusters, if provided, in order to prevent
accidents caused by abrupt moving of the machine.
