Precautions to be taken so as to use the LBH-1790A Series
more safely
1. In case nothing is displayed in the operation panel even when the power switch is
turned ON, turn OFF the power switch and check the power voltage and phase.
2. To avoid personal injury, never put your fingers under the thread take-up lever, cloth
presser, cloth cutting knife, or needle when you turn the power switch ON or operate the
sewing machine.
3. To protect against possible accidents due to abrupt startup of the machine, turn OFF
the power switch before tilting the machine head or removing the motor cover.
4. To avoid personal injury, never bring your fingers, hair or clothing close to V belt, cloth
cutting knife or motor during operation, and never place anything on any of these parts.
5. To avoid personal injury, never operate the machine with the motor cover, eye protection
cover, or any other safety devices removed.
6. To avoid personal injury, be careful never to allow your fingers to go inside the machine
when tilting or raising the machine head.
7. 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.
8. 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).
9. 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 damaged electrical component(s).
10. In the event of a power failure, be sure to turn OFF the power to the machine to protect
against damaged electrical components.
11. This sewing machine should be used under industrial environment. Under general
household environment, the machine may cause poor reception when used in proximity
of the television set or radio.
12. 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.
1. To prevent possible accidents due to electric shocks, neither open the cover of
motor electrical box nor touch the component(s) inside the electrical box.
2. Make sure of the needle entry after changing the pattern. Should the pattern
protrude from the work clamp check, needle interferes with the work clamp check
resulting in the danger of occurrence of needle breakage or the like. In addition,
check that the work clamp check which has been set corresponds to that which
has been installed on the sewing machine.
