1.
Adjustment by the presser bar lifter:
Loosen the screw«D, Fig. 23)sufficiently, raise the presser bar lifter and loosen
the set screw (@. Fig. 23). Move the lifting presser foot (A. Fig. 7) up or
down as may be required so as to get the correct height and tighten the
screws
2. Adjusting the lift of alternating presser feet:
If the height of the lifting presser foot changes, the momentums of the lift-
ing and vibrating presser foot vary. thus the height of the vibrating presser
foot must be adjusted.
To adjust this, lower the presser bar lifter, holding the vibrating presser
foot(B, .Fig. 7) and loosen the hexagon screw (@. Fig. 23) and move the pre-
sser foot up or down as may be required. After setting the position, tighten
the screw.
TIMING OF THE VIBRATING PRESSER FOOT
This is the normal timing when turn the machine pulley toward you, after lo-
wering the presser bar lifter, the vibrating presser foot should reach the feeder
earlier than the needle eye comes to, and when the needle raises. the vibrating
presser foot should leave the feeder after the needle eye has left the feeder.
This is due to the reason that the vibrating presser foot must tightly hold the
go'ods while the needle is passing the goods for avoiding irregular stitches.
To adjust this, set the lift of the alternating presser feet to equal, loosen the
two screws (@. Fig. 23) and adjust the rotating position of the cam (@. Fig. 23)
faster or slower as may be desired, and tighten the screws.
