3 To thread the machine
Thread the machine correctly by referring to pages 3 to 8.
Incorrect threading may cause skip stitching, thread breakage and/or uneven stitch
formation. When threading the looper, tilt the looper holder toward the front of the
machine using the looper drawing bar.
■
To tilt the looper toward the front
1. Bring needle bar A to the top of its stroke.
2. Pay out the needle thread from the spool by pressing a finger down on needle threads
B.
3. Pull looper drawing bar knob C out to the left so that the looper holder is tilted
toward the front of the machine.
4. After the machine is threaded, replace the looper by pressing looper holder D into the
machine until it clicks.
< Note >
The looper pops out of the machine as soon as knob C is pulled, so do not bring your
fingers close to the looper.

Refer to the table below for maximum and standard
speeds of the Series. To extend machine life, run
the machine approximately 15~20% below the
maximum speed for the first 200 hours of operation
(approx. 1 month). Then run the machine at the
standard speed. The machine pulley turns
counterclockwise as seen from the end of the
machine pulley.

Remove oil pot A.
Fill the machine with oil until the oil level is at the
top line (see H in the illustration) on oil gauge C.
After the first lubrication, add oil so that the oil
level will be between H and L.
After filling the machine with oil, run the machine
to check the oil is splashing onto oil pot A.

To extend machine life, be sure to replace the oil
after the first 250 hours of operation.
To replace the oil, follow the procedures below.
1. Remove the V belt from the motor pulley and
then remove the machine from the table.
2. Remove screw D and then drain the oil.
Be careful not to stain V belt with the oil.
3. After draining the oil, be sure to tighten screw
D.
4. Fill the machine with oil by referring to 4-2
shown above.
If filter element E is contaminated, proper oiling
may not be performed. Clean the filter element
every six months. If just a little or no oil flows out
from the nozzle with the proper amount of oil in the
machine, check the filter element. To clean the filter element, remove oil filter cap F.

When the needle, moving from the top to bottom of its stroke, enters the triangle of the
looper thread, the retainer looper should be at the extreme right end of its travel.
To adjust the retainer looper left to right, loosen screws A first. With the retainer looper
at the extreme left end of its travel, set the clearance
between the retainer looper and the right side of the
looper at approximately 0.5mm. Then set the clearance
between the retainer looper and the top surface of the
looper blade at 0.1mm. After this adjustment is made,
tighten screws A.
