Control and Adjustment of the Sewing Machine
Caution
▶ Always turn off the power when mounting a needle. If the operator mistakenly steps on the pedal
while the power is on, the machine will start automatically and can result in physical injuries.
▶ When using clutch motor, be aware that the motor will continue to rotate for a while even after the
power is switched off due to inertia. Start to work on the sewing machine only after the motor has
come to a complete stop.
1) Needle Insertion
With the needle groove① facing left, insert the needle tip
into the upper end of the stopper hole② and fasten the
needle with the clamp screw③. (See Fig. 15)
[Fig. 15]
2) Adjustment of needle bar
As in Fig. 14, remove the needle bar adjusting rubber plug
① from the face plate and spin the pulley to place the needle
bar at the lowest position. Loosen the needle bar holding
screw② and move the needle bar to align the lower end of
the needle bar lower bushing③ with the punch mark④ of
the lowest position of the needle bar. Then tightly fasten the
needle bar screw② and put back the rubber plug① to the
original position.
