2-2 Replacing the needle
When replacing the needle, check the needle carefully to
see that the scarf is turned to the left of the machine (see
the illustration).
< Note >
When replacing the needle, be sure to turn off the machine. A
clutch motor continues running for a while after the machine is
turned off. Therefore keep on pressing the pedal until the
machine stops.

2-3 To thread the machine
Thread the machine correctly by referring to pages 3 to 11.
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.

【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 counterclockwise
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. 28-611)
4-2 To fill the machine with oil
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.
4-3 Replacing the oil and the filter 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 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 reservoir.
