9) Reverse button function
Pressing the reverse button during forward sewing will
start reverse sewing immediately. When you stop the
machine and restart it by stepping down on the pedal with
the reverse button already pressed down, you can perform
reverse sewing from the beginning. When the machine is
in a "stop"mode, you can change the up-down position
of the needle bar by pressing the button.
Lightly pressing the button once when the needle is in a
down-stop position will stop the needle bar in a high
position. Pressing the reverse button twice within less
than a second when it is in an up-stop position will stop
the needle bar in a low position.
10) Adjustment of synchronizer
A. For in-built synchronizer
Adjust the up-stop position of the needle by loosening the clamp screw① on the side with N(U carved signs and moving
it sideways such that the white carved sign③ on the pulley is aligned with the carved sign of arm④ when the machine is
in up-stop position. Adjust the down-stop position of the needle by loosening the clamp screw② on the side with N.D
carved signs and moving it sideways such that the needle bar stops in the point where it is about to up in the lowest
position when the machine is in down-stop position. (Refer to figure 15 and 16)
B. For 470 motor (external synchronizer)
Turn the pulley manually to position the needle bar at the lowest point about to move back up. Then, loosen the fixed screws on
the film as in Figure 10 on page 13 and align the "DOWN"film with the film adjustment baseline and the sensor housing
baseline as in Figures 17 and 18. Tighten the fixed screws just enough so that the film does not rotate. In the same way, place
the thread take-up lever at the highest point, then loosen the fixed screws again and adjust the "UP"film as in shown the
figure. Be careful that the "DOWN" film A that was tightened before does not move when adjusting the "UP" film.
