Adjustment Procedures Results of Improper Adjustment
™ Make adjustment by loosening the screw inside @9 so that @9
is mounted around the intermediate point between 2 holes for
the hook of lifter lever.
™ Adjust the lifting amount of presser foot by turning the cylinder
rod #2 loosening the rod end nut #1. (If the cylinder rod becomes
too small to turn remove the collar #0.)
™ Make adjustment by loosening the nut #3 and turning the screw
#4 so that the clearance between the hinge screw #5 and the
top end of screw is to be around 1 mm when the presser foot
goes down.
™ Too short stroke could cause the
insufficient lifting amount.
™ Too large stroke could cause the
breakage of the spreader,
needle clamp and thread guide.
™ No clearance made between the
hinge screw and stopper screw
could cause the presser foot
floating.
