11 ADJUSTING THE LIFT
OF THE ALTERNATING
PRESSER FEET (Fig 10)
The thickness of the material should control
the height of the lift of the alternating presser
feet. The lift should be just enough for
clearance of the material.
1 ) With normal adjustment both feed lift to equal height: To later lift, loosen the wing nut A and
move the link and stud assembly along the slot-move up to raise the feeding presser foot and
push down to lower this foot. Tighten wing nut upon completion of adjustment. However, some
materials may require unequal height of lift.
2 ) When altering the lift of the lifting presser foot (A Fig 5) unequally against that of the vibrating
presser foot (B Fig 5) or vice versa, see the instructions "19 ADJUSTING THE HEIGHT OF THE
PRESSER FEET"

above, while depressing the reversing lever 1 slightly.
13 ADJUSTING THE HEIGHT
OF THE FEED DOG (Fig 12)

the height of the feed dog by raising or
