1. Keep your hands away from needle when you turn ON the power switch or while the machine is
in operation.
2. Do not put your fingers into the thread take-up cover while the machine is operating.
3. Turn OFF the power switch when tilting the machine head, or removing the belt cover or the V
belts.
4. During operation, be careful not to allow your or any other person’s head, hands or clothes to
come close to the handwheel, V belt and motor. Also, do not place anything close to them.
5. Do not operate your machine with the belt cover and finger guard removed.
6. When tilting the machine head, be sure to confirm that the head support bar is properly attached
to your machine head, and be careful not to allow your fingers or the like to be pinched in the
machine head.
1. To ensure safety, never operate the machine with the ground wire for the power supply removed.
2. When inserting/removing the power plug, the power switch has to be turned OFF in advance.
3. In time of thunder and lightening, stop your work and disconnect the power plug from the re-
ceptacle so as to ensure safety.
4. If the machine is suddenly moved from a cold place to a warm place, dew condensation may be
observed. In this case, turn ON the power to the machine after you have confirmed that there is
no danger of water drops in the machine.
5. To prevent fires, periodically draw out the power plug from the plug socket and clean the root of
the pins and the space between pins.
6. The hook rotates at a high speed while the machine is in operation.
To prevent possible injury to hands, be sure to keep your hands away from the vicinity of the
hook during operation. In addition, be sure to turn OFF the power to the machine when replac-
ing the bobbin.
7. To avoid possible accidents due to abrupt start of the machine, be sure to turn OFF the power to
the machine.
8. 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.
9. When tilting or returning the sewing machine to the home position, hold the upper side of the
machine head with both hands and perform the work quietly so that fingers or the like are not
caught in the machine.
• Before you put the machine into operation for the first time after the set-up, clean it thoroughly.
Remove all dust gathering during transportation and oil it well.
• Confirm that voltage has been correctly set.
Confirm that the power plug has been properly connected to the power supply.
• Never use the machine in the state where the voltage type is different from the designated one.
• The direction of normal rotation of the machine is counterclockwise as observed from the pulley side.
Take care not to allow the machine to rotate in the reverse direction.
• Never operate the machine unless the head base has been filled with oil.
• For a test run, remove the bobbin case and the needle thread.
• Be sure to use your sewing machine with the speed of stitch lowered to 600 sti/min or less for the first
month after installation.
• Operate the handwheel after the machine has totally stopped.
BEFORE OPERATION
CAUTION :
Check the following so as to prevent maloperation of and damage to the machine.
CAUTION :
Note that safety devices such as “eye guard”, “finger guard”, etc. may be omitted from the
illustrations in this Instruction Manual for easy explanation.
When operating the machine, be sure not to remove these safety devices.
