When assembling and disassembling Feed Lifting Wheel L, pay
attention to the left twisted engagement between the screw thread on the left
end
of Feed Lifting Shaft Hand NutJ and,be sure not to damage the screw
thread. The V notch must align with Pin N in assembling (Fig. 29)
G.
Adjust Presser Foot Pressure
The pressure of the presser foot should be adjusted as per the thickness
of sewing fabric. As a rule the pressure should be higher for heavy weight
material and lower for light weight material. When adjusting remove Screw
A and Cover B, and tum Nut C (Fig. 30) clockwise for higher pressure or
counterclockwise for lower pressure.
H.
Adjust Thread Tension
Thread tension
is much related with sewing quality. Too high tension
will cause problems such as puckering, thread breaking, etc, while too low
tension will cause skipping, floating and uneven stitches. As a rule longer
stitches need lower thread tension and shorter stitches need higher thread
tension.
When adjusting, rotate Nut L clockwise for more thread tension or
counterclockwise for less thread tension (Refer to Fig. 6).
