1.Clearing the machine
Before the head is packed, all of the parts of the machine are coated with anti-rust grease, meanwhile
the grease can harden and the dust can cover the machine surface during long time storage and shipment, so,
the dust and grease must be cleared by clean cloth with gasoline.
2.Examination
Although every machine is conformed by strict inspection and test before delivery, the parts of the machine
may be loose and deformed after long distance transportation with jolt. A thorough examination must be performed.
Turn the balance wheel slightly by hand to check if there is running obstruction, parts collision, uneven resistance
and abnormal noise. If any of these exist, adjustment must be made accordingly before running.

Align machine hand wheel belt groove (A) With
motor pulley belt groove (B) by moving moto r(C)
leftward or rightward, Be sure that the belt is not
touched with the table.
a. The optimum tilt angle of pedal against floor is
approx.20 ~30 .
b.Adjust the clutch of motor so that the clutch lever
(C)and draw bar(B)run in line.
c.The machine hand wheel should rotate
counter-clockwise for normal sewing when view
from opposite side of balance wheel. The motor
should rotate in the same direction. The rotation can
be reversed by reversing the plug of motor (turn
over 180 )
d. Adjust the tension of V-belt (F) by moving the
motor up and down .The proper tension of V-belt is
a slack of 10-12mm when the belt is depressed by
fore finger. Release the forefinger, the belt will
resume.

Align pulley B of the bobbin winder with the
outside of the V-belt C, and there should be a proper
clearance between them, so that pulley B can be
touched with the V-belt when latch thumb lever A is
depressed, thereby the V-belt can drive the pulley B
while the machine running. The bobbin winder
should be parallel with belt slit E of the table, finally
fasten two wooden screws D. .

The machine must be oiled at the places with red
mark after the work is over every day. After
lubrication, please run 1 or 2 minutes. .
Trial running is required when new machine is put
into use or use again after storing quite long time.
First uninstall the rubber plug above the machine
head and face plate and oiled by hand, then lift the
presser foot and run the machine at a low speed of
300~400s.p.m for 30 minutes, then increase the
speed gradually. After one month, please choose the
suitalble speed according to the sewing work. .
Turn the balance wheel to lift the needle bar to its
highest position, loosen the needle set screw, and
make the needle groove to the left side of the
operator, then fully insert the needle shank until to
the bottom of the needle bar socket, tighten the set
screw. .
.
Note: Insufficient insertion (Fig. b) or the needle
groove facing to the operator (Fig.c) is incorrect.

The needle thread should be left-twist, holding the
thread by left hand, twist it by right hand at certain
direction (shown as Fig.10), if it changes into tight,
it's left-twist, contrary, it's right-twist. Please use
needle DD x 1 22#~27#, the needle size should
depend on the materials to be sewn. If the thin
needle is used for sewing heavy materials, the
needle will be broken easily, and will also cause skip
and thread broken. On the contrary, the materials
will be destroyed for the big needle hole, so please
select proper needle and thread according to the
materials. .
Turn the hand wheel to lift the needle bar to its
highest position, then threading as following
sequence shown in the Fig.9 .

Bobbin thread should be neat and tight. If loose,
please increase the tension of tension disc A; if not
neat, please move the winder bracket C to adjust,
When adjust, first loose the screw B, then move the
barcket C rightward if the thread is wound to one
side as Fig(b) shown; or move the barcket C
leftward if the thread is wound to one side as Fig(c)
shown until the thread is wound neatly as Fig.(a)
shown, finally fix the bracket.
Note: nylon or olyester thread should be wound
under light tension in particular; otherwise bobbin D
might be broken or deformed. Please don t overfill
the bobbin thread; otherwise the thread will loosen
down from the bobbin. The optimum capacity of
thread is filled about 80% of bobbin outside
diameter and adjusted by screw E.

The stitch length can be adjusted by the button A.
Press the button, then turn the hand wheel B
clockwise to decrease the sitich length or
counter-clockwise to increase the stitch length. After
adjustment, please test the stitch length by paper
until the required length is reached. Finally, please
check the error between forward and backward feed.
If the backward feed is short, turn the screw C
counter-clockwise, then tighten the nut; if the
backwasrd feed is long, turn the screw D to adjust. .

The thread take-up lever and needle bar is lubricated
by oil woolen wick, if the oil wick has no the
function because of the pollution or hardened, please
change a new on:
1. Open the face plate, uninstall the screw, lock
nut.
2. Pull out the pin A, and take out the oil wick.
3. Take out the oil wick in the B
4. Change a new one.
5. The installation steps are counter-sequence.

Adjust the pressure of presser foot according to the
materials. First loosen the nut A, then turn the thumb
screw clockwise (a) to increase the pressure, on
the contrary, to decrease the pressure, after the
proper pressure is obtained, tighten the nut A.
The proper pressure is assure the materials be feed
properly.

The swing range of the thread take-up spring should
be 5~8mm. If stitch the light materials (stitch length
is also short), the spring tension should be lower and
increase the swing range, vice versa.
1. Adjust the tension of thread take-up spring
Turn the screw A clockwise to increase the tension,
on the contrary, to decrease the tension.
2. Adjust the swing range of the spring
Loosen the screw A, turn the disc B clockwise to
increase the swing range, on the contrary, to
decrease the swing range.
Usually the tension and swing range have been set
by the maker, only sewing the special materials or
use special thread, it should be reset.

The normal stitch of sewing machine is shown in
Fig.a. If stitch is abnormal, the puckering and thread
breakage will occur, the needle thread tension and
bobbin thread tension should be adjusted so that the
normal stitch can be obtained.
a.If The stitch seam shows as Fig. B, indicates that
the needle thread tension is too tight or the bobbin
thread tension is too loose. Please turn the thread
tension nut counter-clockwise to release the needle
thread pressure; or turn the bobbin lace adjusting
screw with a screwdriver to increase the bobbin
thread tension.
B.If the needle thread tension is too loose or the
bobbin thread tension is too tight shown as Fig.c
Please turn the thread tension nut clockwise to
increase the needle thread pressure; or turn the
bobbin lace adjusting screw with a screwdriver to
decrease the bobbin thread tension.
C.If the stitch seam shows as Fig,d.e. It also can be
adjusted by referring to above methods.
