Installation of table-top type table
Mount the sewing machine as shown in Figure 6 and 7.
Fix the table with screws and nuts. Place the rubber cushion on the bolt and then fix the oilpan onto the cushion securely.
Mount the sewing machine as illustrated in Figure 8 and 9. First, insert the screw into the bed support bar and fix it onto the table. Then fit the rubber cushion onto the screw and
place the oilpan securely.

2) Installation of motor and belt
Use a 3-Phase, 2-Pole, 400W(1/2 HP) clutch motor and M-type V-belt for the machine.
Start the pedal. When the motor pulley begins to move to the left, adjust the position of the motor so that the centers of the
motor pulley and the M/C pulley meet with each other.
Mount the sewing machine as shown in Figure 10 and 11.
Insert the screw and nut into the table, and place the rubber cushion on the bolt. Securely place the oilpan on the cushion
afterwards.
The diameter of pulleys in the market is generally set with a 5 mm clearance.

4) Installation of belt cover
[ Warning ] Be sure to turn the power switch off before adjusting belt tension.
[ Warning ] Always install the belt cover for safety.
Turn the screwof the motoraround. Adjust the belt
to go in approximately 10~20mm when its center portion is
pushed with a finger. (Refer to figure 13)
[ Figure 13 ]
Fasten the belt cover (upper)with a screwas shown in figure 14. For A-Type table, mount the belt cover (lower)③ as
shown in figure 15.

5) Installing cover for needle bar thread guide
As illustrated in the figure, fix the coverfor needle bar thread guide onto the arm with two screws①.
6) Installation of thread guide plate
Use screws (2 each) to mount the thread guide plate onto the arm as described below in the figure.
[ Figure 17 ]
[ Figure 16 ]
20
[ Warning ] Be sure to turn the power switch off before oiling
[ Caution ] Do not put foreign materials into the lubricating oil. It will degrade the lubricating oil and cause mechanical breakdowns.
The maximum speed of the sewing machine is 6,000 s.p.m,
and 4,000 s.p.m for commercial use. (If a puller is installed,
maximum sewing speed is 4,500 s.p.m, and 4,000 s.p.m for
commercial use.)
To ensure durability, run the sewing machine at 5,000 s.p.m
for 200 hours of operation (or 1 month) when using the
machine for the first time.
As shown in figure 18, the rotating direction of the lower shaft pulleyand upper shaft pulleyis clockwise.
[ Figure 18 ]
1) Lubricating oil
Use industrial-purpose lubricating oil supplied by SunStar or SF oil by YANASE for this particular type of sewing machine.

[ Caution ] Too little oil may cause mechanical breakdowns and too much may degrade the quality of sewing materials. Be sure to adjust the amount of oil appropriately.
3) Oil Gauge and Oil Window
Always check the oil gauge before starting the machine. Supply oil if the remaining oil comes short of the lower line of
the gauge. When operating the machine, check the flow of the oil through oil window ②.
4) Oil change
To ensure durability of the sewing machine, be sure to
change oil after 250 hours of initial operation.
Change oil according to the following. Unfasten oil discharge screw to let out the lubricating
oil.
Fasten oil discharge screwsecurely afterwards. Refer to 2) Supplying oil for lubrication.
[ Figure 21 ]
The sewing machine is not oiled when shipped out from the factory. To ensure trouble-free use of the sewing machine, open the upper rubber lid and supply oil to the upper line of the oil gauge .
