your fingers to come in contact with the hook.
Il If the machine has not been sufficiently warmed up for operation, make the machine run idle
for approximately three minutes. (Moderate intermittent operation)
2)
Place the amount of oil (oil splashes) confirmation paper under the hook while the sewing
machine is in operation.
3)
Confirm that oil exists in the oil tank.

samples on the left should be finely
adjusted in accordance with sewing
processes. Be careful not
to excessively

A needle of DBx l or DPx5 should be used. Select a proper needle size according to the
count of thread and the type of material used.
1. Turn the
hand-wheel until the needle bar reaches the highest point of its stroke.
2. Loosen screw (1), and hold needle (]) with its indented part ® facing exactly to the
right in direction ®.
3. Insert the needle fully into the hole in the needle bar in the direction of the arrow until
the end of hole is reached.
4. Securely tighten screw (1).
5. Check that long groove ©of the needle is facing exactly to the left in direction @.
Caution: When filament thread is used, if the indented part of the needle is tilted toward
operator's side, the loop of thread becomes unstable, As a result, hangnail of
thread or thread breakage may occur. For the thread that such phenomenon is
likely to occur, it is effective to attach the needle with its indented part slightly
slanting on the rear side.

I) Insert the bobbin deep into the bobbin
winder spindle CD until it will go no further.
2) Pass the bobbin thread pulled out from the
spool rested on the right side
of the thread
stand following the
order as shown in the figure on the left. Then. wind clockwise the end
of the bobbin thread on the bobbin several times. (In case of the aluminum bobbin, after
winding clockwise the end of the bobbin thread, wind counterclockwise the thread coming
from the bobbin thread tension several times to wind the bobbin thread with ease.)
3) Press the bobbin winder trip latch <£) in the direction of A and start the sewing machine. The
bobbin rotates in the direction
of C and the bobbin thread is wound up. The bobbin winder
spindle
CD automatically as soon as the winding is finished.
4) Remove the bobbin and cut the bobbin thread with the thread cut retainer ®.
5) To adjust the winding amount of the bobbin thread, loosen the setscrew @) and move the
bobbin winder adjusting plate@ to the direction of A or B. Then, tighten the setscrew @).
To the direction of A: Decrease; to the direction of B: Increase.
6) In case that the bobbin thread is not wound evenly on the bobbin, loosen the nut ® and tum
the bobbin thread tension to adjust the height of the thread tension disk ~-
)> It is the standard that the center of the bobbin is as high as the center of the thread tension
disk.
)> Move the position of the thread tension disk !J) to the direction of A as shown in the figure
on the left when the winding amount
of the bobbin thread on the lower part of the bobbin is
excessive and to the direction
of B as shown in the figure on the left when the winding amount
of the bobbin thread on the upper part of the bobbin is excessive.
After the adjustment, tighten the nut
®.
7) To adjust the tension of the bobbin winder. turn the thread tension nut ®.
Caution:
I. when winding the bobbin thread, start the winding in the state that the thread between the
bobbin and thread tension disk
~ is tense.
2. When winding the bobbin thread in the state that wing is not performed, remove the needle
thread from the thread path

3) As you turn
thread tension nut Q) clockwise (in direction ©l. the needle thread tension
will be increased.
4) As you turn nut Q) counterclockwise (in direction@), the needle thread tension will.be
decreased.
2. Adjusting the bobbin thread tension
I) AS you turn tension adjust screw ~ clockwise (in direction @), the bobbin thread
tension will be increased.

Usually, upon the
machine coming out, all the take-up spring has been adjusted well, only
while sew special material thread, it need to be adjusted again.
To
judge the work of the thread take-up spring, confirm whether or not the thread take-up
spring works up to the last before needle thread is pulled out from @ when pulling out needle
thread in the direction of @after the pressure of the thread take-up spring has been performed.
When it does not work up to the last, decrease the pressure of the thread take-up spring. In
addition. the stroke
of the thread take-up spring is excessively small, the spring does not work
properly.
For the general fabrics, a stroke of 10 to 13 mm is proper.

I. Turn the hand-wheel to bright the needle bar down to the lowest point of its stroke, and loosen
setscrew
CD.
2. Adjusting the needle bar height:
I) While using DB needle, align
marker line A with the bottom end of needle bar lower bushing
Q), then tighten setscrew CD.
2) While using DA needle, align marker line C with the bottom end of needle bar lower bushing
Q), then tighten setscrew CD.
3. Locate the hook position:
1) While using DB needle, loosen the three hook set screw, turn the hand-wheel, and align marker
line B on ascending needle
bar 2 with the bottom end of needle bar lower bushing Q).
2) While using DA needle, loosen the three hook set screw, turn the hand-wheel, and align marker
lineD on ascending needle bar 2 with the bottom end of needle bar lower bushing Q).
4. After making the adjustments mentioned in the above steps, align hook blade point ~ with
the center of needle ®. Provide a clearance of 0.04mm to 0.1 Omm(reference value) between
the needle and the hook, then securely tighten setscrews in the hook.
Caution:
I.
If the clearance between the blade point of hook and the needle is smaller than the specified
value, the blade point
of hook will be damaged. If the clearance is larger, stitch skip-ping will
result.
2. Use a
hook of the same part No, when replacing your hook with a new one.

Height of the feed dog is adjusted so that the feed dog protrudes from the throat
plate surface by 0.75 to 0.85 mm (1 mm for H type). Adjust the height in accordance
with the material to be used.
I.
Adjusting the height and tilt of the feed dog
I) Loosen setscrew Q) in feed bar driving shaft CD and setscrew ® in feed bar rocker
shaft Q)
2) Height and tilt of the feed dog will change by turning both shafts CD and @ with
a screwdriver.
3) For the relation between the rotatincr direction of each shaft ~nd tilt of feed bar®,

Caution:
I.
If the tilt of the feed dog is adjusted with one shaft only, the height of the feed dog changes.
Be sure to adjust it with both shafts.
2. Movement position of the feed dog may be shifted depending on the adjusting position of the
shaft. At this time, loosen setscrew
