B. Check for down-stop position of needle bar
The down-stop position of needle bar is where the carved
sign① of the needle bar coincides with the tip of the needle
bar frame②. If the position is not suitable, move the
magnetic holder③ built in a carved N.D. sign of the pulley
to the left and right for adjustment.

Pressing the back tack button or reverse button① 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 button① already pressed down, you can
perform reverse sewing from the beginning. When the
machine is in a “stop”mode, you can change up-down
position of the needle bar by pressing the reverse button.
Lightly pressing the button once will stop the needle bar in a
high position. Pressing the reverse button① twice within less
than a second will stop the needle bar in a low position. In
short, the button delivers two functions: one for reverse sewing
and the other for converting vertical position of the needle.
