1, Safety operating guide .
1) When turning the power on, keep your hands and fingers away from the area under
the needle and around the pulley.
2) Power must be turned
off when the machine is not used or when the operator leaves
his/her seat.
3) Power must be turned off when incline the machine head, install/remove the belt or
move machine.
·4) Don't place finger, hair, shaft etc. near pulley, belt, wheel and motor in order to avoid
injury.
5) Don't insert finger into the thread take up lever guard cover, keep your hands and
fingers away from the area under the needle and around the pulley when the machine
is
in operation.
6) Don't operate the machine without the safety devices
if the belt cover or eye guard
are installed.
2, Operating notice
1) Don't operate the machine if the oil tank without full oil.
2) The machine adopt semi-automatic lubricating mode. Don't operate the machine
before lubricating.
3) Check the rotation direction
of pulley when firstly start new machine. (The pulley
should rotate in counterclockwise when viewed from pulley)
4) Check the voltage and phase. (Single or three whether is corresponds with the data
in motor nameplate)
3, Operating condition
1) Avoid using machine at abnormally high temperature (40°C or higher) or low
temperature
(5 °C or lower). Otherwise machine failure may result.
2) Avoid using machine in dusty condition.

5, Power cable connection
1) When con_necting the power cable to control box, it should confirm the connector
type and machine direction firstly and then plug
the connector into proper receptacle
completely.
2) Rotary direction: Please refer the instruction book -of confected motor if it needs to
change the rotary direction of motor.
6, Control box connection
The control box should be
connected as shown in fig.1.
Note:
(1) Be sure to turn the power
switch off for safety before
connecting or disconnecting
the connector.

7, Install belt(Fig.2)
1) Use V-belt which special for sewing machine.
2) To adjust the tension of belt. Change the height of
motor through turn the tension adjustive nut. It is ok if
the belt can be sink inside with 15mm when pressing
the center posit~on
of belt surface. Lacking tension will
cause unstable running speed
of machine, or needle
stand
at wrong stop position when machine in middle/
slow running condition. Excessive tension will cause
the motor bearing be damaged.
8, Install belt cover
It must install belt cover for machine head and motor
for safety.

for the adjustment method.
1)
"Up" Position
When the pedal is kicked down by heel, the
machine should stop at "Up" position, i.e.
the highest position
of take-up lever.
2) "Down" Position
When the pedal is stand at middle position, the
machine should stop at "Down" position,
i.e.
the needle bar raises 3mm from its low~st position.

10 , Operation guide (motor and control box}
1)Keep foot away from pedal when tu rn onto~ the power. Po wer must be turned off when
the operator leaves his/her seat.
2)The detent can't work when the power is interrupted or power failu
re occurs during the
machine operation.
3)Keep the control box cover is closed during operation in order to avoid accidental
operation since the
dust come into control box.
4)Must use multimeter to check control loop circuit in order to protect the semiconductor
parts.
5)Power must be turned off when incline machine head only
or touch needle.
6)Must use earthing cable (with yellow/green color) to connect motor.
?)When check the inter circuit, it must turn
off the power firstly and then open the front
cover.
8)1t must wait 1Ominutes after turn off the power due the high voltage in box. (It is very
importance to release the inside energy.)
9)Keep motor away from much noise area

11- To lubricate the machine
Clean the m·achine completely before operate
it daily, and check the oil quantity
of hook oil
tank. Then inject oil as arrow shows in fig.3 and
fig.4, start operation
of machine.

The hook, feed dog and other parts of machine should be cleaned dai ly, and drop two
or three coal oil into hook
an d other piace that need to be lubricated. Clean all the
spilth after ending
of highest speed ope~ation of machine, then lubricate the machine
with oil. The clean work
must be ins '. sted every day. (Especially the machine wor k ed
one week, the clean work,is very ir.ioc,tance. Oi the spilth will affect the s'ewing
capability and rust hook and r.:ae;~:ne. !t sh0u!d

Maintenance of motor: Clean dust of the motor cover each one or two month. (More
dust or sundries
of motor cover will make it too heat.)
Maintenance
of control box: Clean dust of the connector. ( It will affect accidental
operation
if there is more dust on the connector .)
Warning:
Before proceeding to clean and libr at ing the machine, be sure to switch offa ll switches
and hold your feet away from the machine stand pedal in
order to avo id accidental
machine start by pedal actuation.
14, Wind the bobbin(Fig.5)
1) Insi de winder (Fig.5)
Pass
the thread through the thread guide (6)
from
the thread stand, wind it few times
anticlockwise on the bobbin and put
the
bobbin on the winder shaft (1 ). Switch on the
motor and depress the treadle lightly
to start
the machine and by this winder as well. The
winding amount (See Fig.6) is 80% of full •
capacit
y. It can be adjusted by loosen in g the
screw (4)
of the control lever (5) mounted on
the disconnecting pin (3). When the winding
is completed, using the knife mounted
in the
spring (2) cut
off the thread end.

Insert the bobbin case with
the bobbin into the hook. To prevent the bobbin from fallig
out
of the case, while being inserted into the hook, tilt the lock .fixing the bobbin in the
case. With
your thumb, push the bobbin case in until you hear a short distinct sound.
The correct position
of the bobbin case in the hook signaled by this sound is very
important,
because otherwise a needle rupture or another breakdown could occur at
the following machine start.
17, To thread upper thread(Fig.8)
Let the take up lever at its highest position.
Then threading
as shown in Fig.8.
Unwind a sufficient portion
of thread, and pass
it through the thread guide (1) and (2), then lead
it through the
tension disc (6) and thread take up
spring (5), thread
guides (7), (4) and (3) into the
thread take-up lever. Then downwards through
the thread guide (4) and the lower thread guide (8)
to
the thread guide (9) on the needle bar, and to
the needle. Insert it into the needle ear from the
front side to the rear side.
18, To catch lower thread
Hold the end part of upper thread by left hand;
turn the pulley
wheel slowly by right hand. The
upper thread was being took up and lead the
lower thread out. Make them coordinative, then
pass them through the underside of presser foot,
put them behind
th,'e position of needle. Put some '------..-. _____ _.
materials under presser foot before start sewing. F1g.8
The take up level must at its highest position when start and end th~ sewing.

24, The gap between hook assembly and needle adjustment(Fig.16)
Adjust the stitch forming width to zero and turning round the hand wheel towards the
machine, when the needle goes up 2mm from the lowest position, the position of needle
hole should be lower 1.6mm ti

with
the centerline of needle and the gap from hook top to needle slot bottom should be
0.05mm.

25, The feed dog height adjustment (Fig.17)
The height of feed dog should be higher 1.0mm than needle plate. It is the standard for
leaving factory. The height
of feed dog can be adjusted to 0.8-1.2mm according to sewn
material.
To adjust it, turn pulley wheel to the highest position of feed dog, loosen the
screw (2) of the lifting lever (8) or: t~:s shaft (6), adjust it to the required height of the
