5, Power cable conneption
1) When con,r,e!cting the power cable to control box, it should confirm the connector
type and mac,hirie direction firstly and then plug the connector into proper receptacle
completely.
\' ·· · . ·
2) Rotary directlon: Please refer the instruction book -of confected motor if it needs fo
· change the rotary direction of motor. ·
6, Control box conne~tion
The control box should be
connected
as shown in fig.1.
Note:
(1) Be sure.to turn the pqwer
switch off for safety before
connecting or disconnecting
the connector.
(2) Machine type must si.lit for
control box ofmotor.
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 position 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.
Fig.1
Fig.2
9, The needle bar stop position adjustment
Note: It adopts outside localizer, please refer the instruction book of confected motor
for the adjustment method. · ·
1) "Up" Position
When the pedal is kicked down by heel, the machine should stop at "Up" position,
Le.
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.

1 O, Operation guide (motor and control box)
1)Keep foot away from pedal when turn on/off the power. Power must be turned off when
the operator leaves his/her seat.
2)The detent can't work when the power is interrupted or power failure 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 contrnl box. ·
4)Must use multimeter to check control loop circuit
in order to protect the semiconductor
pa~. . . .
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 such as high frequency joint area when use it
11, To lubricate the machine
.Clean the machine 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 ma'chine.
12, The hook lubricating condition
adjustment(Fig.4)
· _:r.o----adjust hook lubricating through screwA which
site before oil tank
of hook.
1)The oil quantity is lowest when ·screwA was
turned with clockwise and the arrow points to
"O"
position.
2)The oil quantity is highest when screwA was
turned with anticlockwise and the arrow points
to "MAX" position.
Fig.3
LJ
13, Time machine cleaning Fig.4
. The hook, feed dog and other parts
of machine should be cleaned daily, and drop two
or three coal oil into hook and other place that need to be lubricated. Clean all the
spilth after endihg
of highestspeed operation of machine, then lubricate the machine
with oil. The clean work must
be insisted every day. (Especially the machine worked
one week, the clean work0
is very importance. Or the spilth will affect the sewing
capability and rust hook and machine. It should to take away bobbin from hook before
cleaning.)

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 librating the machine,
be
sure to switch off all switches
and hold your feet away from the machine stand pedal in order to avoid accidental
machine start by pedal actuation. ·

14, Wind the bobbin(Fig.5)
1)
Inside 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 wihder
as
well. The
winding amount (See Fig.6) is
80%
of full •
capacity. It can be adjusted by loosening the
screw
(4)
of
the control lever (5) mounted
on
the disconnecting pin (3). When the winding
is completed, using the knife mounied
