After filling the machine with oil, run the machine to
check the oil is splashing to oil flow sight window C and F.
When starting a new machine after filling the reservoirs,
or when beginning to operate a machine that has been
idle for some time, it may be necessary to prime the pump.
To do this, remove the two plug screw G.
Apply oil from an oil can to these holes and operate
machine until bubbling can be observed at the windows.

【6】TIMING OF THE LOOPERS TO THE NEEDLES
■Timing of the looper to the needle is factory-set properly.
However, when disassembling the needle bar mechanism, looper mechanism or using a
new part, this timing should be readjusted. Refer to the following procedures.

-1 To adjust the timing
1 To adjust the timing1 To adjust the timing
1 To adjust the timing
1. Remove the needle, needle plate, presser foot, feed
dog and auxiliary feed dog and feeding roller.
2. Remove the front looper. Then install test bar A
(diameter : 3.97). Tighten screw B.
3. With the looper holder at the extreme right end of
its travel, position test bar A so that it is normal to
the throat plate. Adjustment is made by
loosening screw C and positioning the looper
holder again.
4. Bring test bar A to the extreme left end of its
travel.
Then install the needle plate.
5. Turn the machine pulley counterclockwise slowly
until the test bar touches slightly the needle plate.
6. Fit timing gauge D onto the underside of the
machine head. Then secure it on the needle bar.
7. Turn the machine pulley clockwise slowly until
timing gauge D touches the machine head or test
bar A touches the needle plate.
Clearance between timing gauge D and the
machine head or test bar A and the needle plate
should be within 0.1mm. If it is, the timing will
be correctly achieved. If it is more than 0.1mm,
follow the procedures below.
8. Remove the cover of the crank chamber and
packing. Loosen screws F of joint collar E.
If timing gauge D touches the machine head before
test bar A touches the needle plate while the
machine pulley is turned slowly clockwise, the
looper timing is fast. Therefore fix the crankshaft
and turn main shaft G clockwise.
If test bar A touches the needle plate and there is a
clearance between timing gauge D and the
machine head, the looper timing is slow.
Turn main shaft G counterclockwise.
■Every time joint collar E is readjusted, perform 6, 7 and
8 procedures repeatedly.
To do so, tighten any one of screws F temporarily.
After the adjustment has been achieved, tighten screws
F securely. Then make sure the correct timing is
obtained by referring to the above procedures.

The looper passes behind the needle when it moves
from the extreme left end of its travel to the right.
When the point of the looper has reached the center of
the needle, the looper should be as close to the needle
as possible with no contact between the looper and the
needle. Adjustment is made by loosening screw K on
the looper holder. When the looper moves to the left
from the extreme right end of its travel while the
needle is descending to the back of the looper blade,
check to see if the needle touches slightly the back side
of the looper. If the needle is bent by the looper or
there is a clearance between the needle and the looper,
adjust the amount of looper front-to-back movement by
referring to the below.

< Note >
Since the needle guard is installed on the feed dog bracket,
the relationship between the needle and the needle guard
varies according to the stitch length. Therefore readjust the
needle guard if the stitch length is changed.
【7】ADJUSTING THE NEEDLE GUARD
When the looper moves to the right from the extreme left
end of its travel, the looper passes behind the needle.
When the point of the looper has reached the centerline of
the needle, the needle should be 0 ~ 0.5mm deflected by
needle guard M. Adjustment is made by loosening screw
N. The needle guard should be installed as low as
possible. In addition, the needle must touch the needle
guard surface until the point of the looper passing behind
the needle reaches the right side of the needle.
Adjustment is made by loosening screw O.

The presser foot pressure should be as light as
possible, yet be sufficient to produce uniform
stitches and feed the fabric properly.
If the pressure is too light, the fabric may not be fed
evenly or skip stitching and/or uneven stitching may
occur. Adjustment is made by loosening screw A
and turning adjusting screw B.
To increase the pressure, turn adjusting screw B
clockwise. To decrease the pressure, turn adjusting
screw B counterclockwise.

To make this adjustment, loosen screw B of the presser
bar clamp and turn the presser bar.
■To adjust the presser bar clamp
Loosen screw B of the presser bar clamp with the

■To disassemble the feed roller
1. Remove screw A on the feed roller presser bar
clamp. Loosen screw B.
2. Loosen screw D on feed roller bracket C.
3. Raise the feed roller presser bar as required.
Remove feed roller bracket C.
■To reassemble and adjust the feed roller
1. Insert the feed roller presser bar into the feed
roller presser spring, feed roller presser bar clamp
and then feed roller bracket.
2. Replace screw A of the feed roller presser bar
clamp.
Tighten screw A until it contacts the flat spot on
the feed roller presser bar. Tighten screw B.
3. Create a clearance of approximately 0.1mm
between the feed roller and the needle plate with screw E of the feed roller presser
bar clamp touching the surface of the casting on the machine head. Then tighten
screw D.
If the feed roller contacts the needle plate when the machine runs with no fabric, the
feed roller will be worn out. This clearance (0.1mm) prevents the feed roller from
being worn out.
■Interlock between the feed roller and the presser foot
Pressing the presser foot lift pedal raises simultaneously the presser foot and the feed
roller.
The feed roller is factory-set to be raised shortly after the presser foot is raised.
Adjust the timing at which the presser foot and the feed roller are raised according to
sewing conditions. Refer to the procedures below.
1. Loosen screw D to release the feed roller.
2. Loosen nut F. Turn adjusting screw E clockwise or counterclockwise as required.
To advance the timing at which the feed roller is raised, turn adjusting screw E
counterclockwise. To delay the timing at which the feed roller is raised, turn
adjusting screw E clockwise.
3. Lock adjusting screw E with nut E.
4. Create a clearance of 0.1mm between the feed roller and the needle plate.
Tighten screw D.

To tighten the needle thread, move needle thread
eyelet (left) A downwards.
■Needle thread guard
Needle thread guard D adjusts the needle thread
tension after the looper has withdrawn from the needle
thread loop and the shape of the needle thread loop
which the looper enters. When the needle bar is at
the bottom of its stroke, needle thread guard D should
be 1.5mm above the top end of needle bar lever eyelet
E.
Moving needle thread guard D upwards increases the
size of the needle thread loop.
Moving needle thread guard D downwards decreases
the size of the needle thread loop.
Adjustment is made by loosening screws F.

When the looper starts moving to the left from the
extreme right end of its travel, looper thread take-up
cam G should begin to cast off the looper thread.
Adjustment is made by loosening screws H.
To increase the amount of looper thread to be supplied,
advance the timing at which the looper thread take-up
cam starts casting off the looper thread for the looper.
When adjusting looper thread take-up cam G, be
careful not to move it front or back.
