5. Feeding frame automatically comes down when pattern is changed, ready key is ON, Press-
er switch is ON, intermediate presser button is ON and bobbin winder button is ON. To
prevent possible accidents caused by abrupt start of the sewing machine, never place your
fingers under the feeding frame.
6. To avoid personal injury, never bring your fingers, hair or clothing close to V belt, cloth cut-
ting knife or motor during operation, and never place anything on any of these parts.
7. To avoid personal injury, never operate the machine with the motor cover, eye protection
cover, or any other safety devices removed.
8. To prevent personal injury or death, do not operate the sewing machine with its covers re-
moved.
9. The operation panel displays safety warnings. It is necessary therefore to first verify normal
display on the panel when the power switch is turned on, before operating the sewing ma-
chine.
10. To prevent personal injury or death, do not press the hand pulley while the sewing machine
is in operation.
11. To avoid personal injury, be careful never to allow your fingers to go inside the machine
when tilting or raising the machine head.
12. To prevent possible accidents due to electric shocks or damaged electrical component(s),
always turn OFF the power switch before connecting or disconnecting the power plug.
13. During thunder and lightning storms, stop your work and disconnect the power from
the outlet to ensure safety and prevent possible accidents due to damaged electrical
component(s).
14. If the machine is suddenly moved from a cold place to a warm place, dew condensation
may result. If this occurs, be sure to confirm that there are no potentially dangerous water
drops in the machine before turning it on in order to prevent possible accidents due to dam-
aged electrical component(s).
15. In the event of a power failure, be sure to turn OFF the power to the machine to protect
against damaged electrical components.
16. This sewing machine should be used under industrial environment. Under general house-
hold environment, the machine may cause poor reception when used in proximity of the
television set or radio.
17. When the sewing machine is used without a break for many hours, the temperature of a part
of the machine body or the rear side of operation panel rises higher by 15˚C than the envi-
ronmental temperature, and you may feel the heat from the part. However, this phenomenon
is not abnormal, and does not affect the components or the like.
18. Do not lubricate the machine oil to the places other than the oil tank and the hook section.
The grease lubricating system except the hook section is employed for this sewing ma-
chine, and the grease flows out when lubricating the machine oil resulting in worn-out of
the components.
19. Be careful of handling this product so as not to pour water or oil, shock by dropping, and
the like since this product is a precision instrument.
20. This is a Class A product. In a domestic environment this product may cause radio interfer-
ence, in which case the user may be required to make corrective actions.
21. In order to prevent possible accidents due to a ground fault or a dielectric voltage, an ap-
propriate power plug should be installed by a person who has expertise in electricity. In
addition, the power plug should be connected to the receptacle which is properly grounded
without exceptions.
22. In order to prevent possible accidents due to a ground fault, the earth cable should be prop-
erly grounded.
23. For the control box to be connected to the LK-1900AN Series, use the exclusive control box
for the LK-1900AN Series. (If the control box for the LK-1900A Series is connected to the
LK-1900AN Series sewing machine, a malfunction can be caused.)
