Machine. Before operating this machine, please study this book thoroughly, understand the functions
and features of the machine. Then it will help you to increase your sewing efficiency and quality.
ATTENTION: Because this is an ultra high speed machine. Do not run it before filling oil and
i::king sure the correct turection of motor.
ffi
1. Install the machine according to the table cut-out diagram, Cushion Rubber and Rest Board as enc-
losed. In case of semi-submerged, the distance between Needle plate top surface and Table Top is
about 100mm, and for fully-submerged is about 5mm.
2. Setting the pedal of clutch motor to the left side and the pedal of presser foot lift at right ride.
3. Install the cloth waste chute, thread stand as parts list.
4. Be sure the motor turning direction is clockwise. And the belt can be pressed inward about 10mm.
NOTE: The dimensions of motor pulley and sewing speed are shown in Table 1.
Please run the new machine in the first four at20Vo less speed than maximum. Then replace the
new oil and threafter the machine may be operated up to maxim um speed.
Lubricatdn.And' age
1. Lubrication Fig.l
Remove Screw A and fill in enclosec ultra high speed lubricate oil (or similar to Mobil#lO, Esso#32)
until the top of Oil level indicator between two lines of Oil Level Sight Window, Then replace Screw A.
When the machine is operated for the first time is was idle for a long time, please be sure to oil the
top of the needle holder, guide, upper looper guide etc . before operating the machine.
2. Drainage Fig.2
Remove Screrv A and drain out the oil then eplace Screw A.
For keeping the good lubrication and machine life. please replace the new oil when the new machine
has been operating over four weeks, And after that, change oil every four months.
This machine has been fixed with oil filer, Please clean it every month or replace a new one if nec-
essary.
3. Needle Cooling Lubrication Silicon oil.
