SAFETY INSTRUCTINONS
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.
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.
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.
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.
