【2】NEEDLES & THREADING THE MACHINE
2-1 Needles
DV×57 of Schmetz or Organ.
Select the proper needle for the fabric and thread to
be used.

Schmetz Nm75 Nm80 Nm90 Nm100
Organ #11 #12 #14 #16
2-2 Replacing the needle
When replacing the needle, check the needle
carefully to see that the scarf is turned to the left
(see the illustration).
2-3 To thread the machine
Thread the machine correctly by referring to pages 3
to 5. 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 >
Be sure to turn off the machine before replacing the
needle. A clutch motor continues running for a while
after the machine is turned off. Therefore keep on
pressing the pedal until the machine stops.
< 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.

【3】MACHINE SPEED
3-1 Machine speed & direction in which the machine pulley runs
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
clockwise as seen from the end of the machine
pulley.
3-2 Motor & belt
Motor : 3-phase, 2-pole, 400W clutch motor
Belt : M type V belt
Select the proper motor pulley according to the
machine speed (refer to the motor pulley outer
diameter on the table below).
Adjust the position of the motor by pressing the
finger onto the middle of the belt so that 1~2cm
deflection can be achieved (see the illustration on
the right).

【4】LUBRICATION
4-1 Oil
Use Kansai Special’s genuine oil.
(Part No. 28-613 : 1000 cc)
4-2 To fill the machine with oil
Remove rubber plug A from the oil hole.
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.
4-3 Replacing the oil and the oil element
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 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 element.
To do so, remove oil filter cap F. Replace the element if necessary.
< Note >
When the oil filter cap is rem ved, the oil collected on the element drips. Be careful. o
