Installing on the 470 motor
Assemble the parts in numerical order as shown in Figure 10. Later, adjust the synchro shaft by moving it horizontally so
that the photo film is located at the center of the photo interrupt. Then, fasten tightly with the two fixing bolts using a
hexagonal wrench.
[Caution]
a) Start assembling, after confirming that “DOWN”and “UP”marks are located in the frontal side from the pulley as
shown in FIGURE 10.
b) Film adjustment is already set up in time of delivery.

In case of using sewing machines that have not been
used for a long time, or new products delivered a long
time ago, open the face plate and spray oil using
lubricator to the thread take-up connecting part ① and
fraction parts such as needle bar ② and pushing bar ③.
When you do test running of machines, run
intermittently the machines for about 10 minutes at
rotation of 1,500 spm.
For the first 4 to 5 days, run the machine less than 1,500
spm per minute, and later, run the machine at the normal
rotation so that the machine can maintain its excellent
function.

8) Check for machine stop position (for automatic trimming type)
Check for the machine stop position after moving the needle up and down by pushing the reverse button. See whether the
carved line of pulley is aligned with the carved line of arm when the needle is in an up position. If not, adjustment to the
location of the magnetic holder or to the photo film of the synchronizer will be necessary. The needle’s up-stop position
should be identical with the stop position of the needle bar after the trimming operation.
