accessories when oil is short.
*The oil tank which is filled with oil is only for
lubricating to the hook portion. It is possible to
reduce the oil amount when the number of
rotation used is low and the oil amount in the
hook portion is
(Refer to .
[ ]
1. DO not lubricate to the places other than the oil tank and the hook of Caution 2 below.
Trouble of components will be caused.
2. When using the sewing machine for the first time or after an extended period of disuse
use the machine after lubricating a small amount of oil to the hook portion.(Refer

insert it into the shuttle shaft, and
close the latch.
Set the bobbin into bobbin case in the
direction shown in the figure.
Pass the thread through thread slit of
bobbin case and pull the thread as it is. By
so doing, the thread will pass under the tension
spring and be pulled out from thread hole .
Pass the thread through thread hole of
the horn section, and pull out the thread by
2.5cm from the thread hole.
Turn of the power before starting the work so as to prevent accidents
caused by abrupt start of the sewing machine.

is 8 to 10 mm, and the pressure at the start is
0.1 to 0.3N.
.Adjusting the stroke
Loosen setscrew and turn thread tension
asm. .Turning it clockwise will increase the
moving amount and the thread drawing amount
will increase.
.Adjusting the pressure
To change the pressure of the thread take-up
spring, insert a thin screwdriver into the slot of

MAINTENANCE
1. Adjusting the height of the needle bar
Turn OFF the power before starting the work so as to prevent
accidents cause by abrupt start of the sewing machine.
F type only
Bring needle bar to the lowest position of its stroke. Loosen needle bar connection
screw and adjust so that upper marker line engraved on the needle bar aligns with the
bottom end of needle bar bushing, lower . For F type only, adjust the needle bar to the
position where it is lowered by 0.8 mm to 1 mm from the center of upper marker line
engraved on the needle bar.
After the adjustment, make sure that there is no uneven torque. When stitch
skipping occurs in accordance with the sewing conditions, adjust the height of the
needle bar so as to lower it by 0.5 to 1 mm from the needle bar engraved line .
2. Adjusting the needle-to-shuttle relation
Turn OFF the power before starting the work so as to prevent
accidents cause by abrupt start of the sewing machine.
.Turn the hand wheel by hand. When
needle bar has gone up, adjust so that
lower marker line engraved on the needle
bar aligns with the bottom end of the needle
bar bushing , lower.

.Loosen setscrew in the driver.
Open inner hook pressers to the
right and left, and remove inner hook
presser .
At this time, be careful not to let
inner hook come off and fall.
.Adjust so that the blade point of inner
hook aligns with the center of needle ,
and that a clearance of 0 mm is provided
between the front end of the driver and the
needle as the front end face of driver
receives the needle to prevent the needle
from being bent. Then tighten setscrew of
.Loosen setscrew of the shuttle, and
adjust the longitudinal position of the
shuttle. To do this adjustment, turn shuttle
race adjusting shaft clockwise or
counterclockwise to provide a 0.05 to 0.1
mm clearance between needle and the
blade point of inner hook .
.After adjusting the longitudinal position
of the shuttle, further adjust to provide a
7.5 mm clearance between the needle and
the shuttle by adjusting the rotating
direction. Then tighten setscrew of the
shuttle.
Apply a small amount of oil to race section and oil wick , and use the
sewing machine after an extended period of disuse or cleaning the
periphery of hook portion.

4.The moving knife and counter knife
(2) . Remove six set screws of the top
cover, and take off top cover.
(3). Apply L-shaped wrench to socket
bolt of clamp , and loosen the
socket bolt.
(4). Push down L-shaped wrench to
increase the lift of the work clamp foot, or
pull it up to decrease the lift.
(5). After the adjustment, securely tighten
socket bolt .
(6). If the right and left work clamp feet
are not leveled, loosen fixing screw
and adjust the position of the work clamp
foot lever support plate to level them.
At this time, be careful not to cause work clamp foot lever support plate to
interfere with feed bracket .
If the work clamp foot lever support plate interferes with the wiper, readjust the
height of the wiper using setscrew in the wiper installing base.
Turn OFF the power before starting the work so as to prevent accidents
cause by abrupt start of the sewing machine.
.Loosen adjusting screw so that a
clearance of 18.5 mm is provided between
the front end of the throat plate and the top
end of thread trimmer lever, small . To
adjust, move the moving knife in the
direction of arrow.
.Loosen setscrew so that a clearance of
0.5 mm is provided between needle hole
guide and counter knife . To adjust,
move the counter knife.
Turn OFF the power before starting the work so as to prevent accidents
cause by abrupt start of the sewing machine.
(1) With the machine in stop mode,
remove two set screws of the right
decorative panel ,then remove the
decorative panel along the K direction.

Loosen screw to adjust so that a
clearance of1.5 mm or more is
provided between the wiper and the
needle.
At this time, the standard of the
distance between the wiper and the
needle is 23 to 25 mm. By adjusting
the distance wide, the work clamp
foot can prevent stepping on needle
thread when it comes down.
Especially when the thin needle is
used, adjust the distance wide to
such an extent of 23 mm.
The position of the needle is
when the sewing machine has
stopped after the sewing finished.
6.Draining waste oil
7.A mount of oil supplied to the hook
When polyethylene oiler
becomes filled with oil, remove
polyethylene oiler and drain
the oil.
1) Loosen setscrew and remove
setscrew .
2) When screwing in adjustment
screw , the
amount of oil of oil pipe, left can
be reduced.
3) After the adjustment, screw in
setscrew and fix it.
1. The state of standard delivery is the position where is lightly screwed in and returned
by 4 turns.
2. When reducing the amount of oil, do not screw in the screw at once. Observe the state for
approximately half a day at the position where is screwed in and returned by2turns. If
reducing is excessive, worn-out of the hook will result.
5. Adjusting the wipper

8.Replenishing the designated places with grease
When the sewing machine has been used for a certain number of times of sewing, error
code No. E221 is displayed on the operation panel at the time of turning ON the power. This
display informs the operator of the time of replenishing the designated places with oil. Be sure
to replenish the places with the oil below. Then call the memory switch No. 245 and set it to
"0" with the RESET key. Even after the display of the error No. E221, when the RESET key is
pressed, the error is released, and the sewing machine can be continuously used. Afterwards,
however, the error No. E221 is displayed every time the power is turned ON.
In addition, when the sewing machine is used further for a certain period of time after the
display of error No. E220, the error No. E221 is displayed and the sewing machine fails to
operate since the error cannot be released even when the RESET key is pressed.
When the error No. E221 is displayed, be sure to replenish the designated places below
with oil. Then start up the memory switch and set No. 245 to "0" with the RESET key.
.Outflow the residual oil in gearbox
.Lubricate the upper gearbox
After replenishing the places with oil, the error No. E220 or No. E221 is displayed again
unless the memory switch No. 245 is changed to "0".
Turn OFF the power before starting the work so as to prevent accidents
cause by abrupt start of the sewing machine.
1) Tilt the machine, remove the screws
and seal .
2) put back sewing machine, outflow the
residual oil in the gearbox.
3) tilt the machine again, put back the seals
and screws , then put sewing
machine back to the position.
1)
2)
When through the oil window , you can not
find oil outlet obviously, or it is without oil outlet,
you should add the oil into the wheel gear box.
Turn off the machine, you can take down the
screw and the rubber washer ,when it is
without oil outlet, please add 100ml 10# white
oil; when it is not oil outlet obviously, please
add 50-70ml.Please install back and parts,
