I. CAUTIONS BEFORE OPERATION

Following items have to be checked every working day before the operation of the machine and before the start of work hours.

1.Ascertain that the sewing machine is filled with the predetermined amount of oil.

2.Never operate the machine unless the lubricating part in the hook has been filled up with oil.

3.Ascertain that the pressure gauge indicates the designated air pressure of 0.5 MPa.

*(This is necessary particularly when the compressor is stopped for a lunch break or the like.)

If the compressed air pressure is equal to or less than the designated value, troubles such as interference between the parts can occur. It is therefore necessary to carefully check the compressed air pressure.

4.Check whether the needle thread/bobbin thread need to be replenished.

5.To perform sewing immediately after turning ON the power switch, perform trial stitching first, then proceed with sewing of actual products after the test sewing.

6.In order to prevent the optical fiber sensor of the bobbin thread remaining amount detecting device from showing a detecting failure, be sure to clean thread waste around the hook using an air gun once or more times a day.

7.In order to protect the flap sensor from showing a detecting failure, be sure to clean dust on the reflecting tape of the folding plate using an air gun once or more times a day.

3. HOW TO WIND THE BOBBINS

CAUTION :

To prevent damage, avoid contact with bobbins while the machine is in operation.

				Put bobbin into the thread winder
				shaft until it will go no further.
				Pass thread through thread guide
				plate , open thread tension disk
				and put the thread into the slit of
				thread tension rod .
				Pass thread in the order as shown in
				the figure, and wind the thread onto
	Direction of
				bobbin by four or five turns. (The
	rotation
				direction of the arrow corresponds to
				the direction of rotation of the bobbin.)
				Press bobbin thread guide and
				the bobbin rotates.
				The thread winder will automatically
				stop as soon as it has wound up the
				bobbin to a predetermined amount.

1.If you want to wind a bobbin, start winding it from recess as illustrated in the figure above. If you start to wind a bobbin from portion , the detection of run-out of bobbin thread will fail to be performed normally.

2.To ensure the appropriate remaining amount of bobbin thread, it is important to wind the bobbin uniformly. Be sure to check that the bobbin is uniformly wound particularly at the start of bobbin winding.

If the bobbin fails to be uniformly wound with thread, properly adjust the lateral position of tension post socket .

3.It is most suitable to wind the bobbin with thread to approximately 80% of the outer diameter of the bobbin. The winding amount can be adjusted with winding amount adjustment screw .

4.Do not press lever except when winding bobbin thread. Motor continues to run and trouble will be caused.

5.When abnormalities such as overload of the thread winding motor, etc. are delected, thermal switch is shut off. When thermal switch is shut off, turn ON thermal switch again after turning OFF it to return.
