Adjustment Procedures Results of Improper Adjustment
1) Adjusting the longitudinal position
1. Loosen two setscrews 2 in the feed dog, move feed dog 2
longitudinally (direction of the arrow mark), and adjust so that
A is equal to B.
2. Set the stitch dial to the maximum 10 mm and check that throat
plate 6 and feed dog 2 do not interfere with each other.
(Caution) At the same time, check that there is no interference
between the throat plate and the feed dog when
the feed amount is maximum.
2) Adjusting the lateral position
1. Loosen two feed bar setscrews 3, move the feed dog to the
left or right and adjust so that clearance between feed dog 2
and throat plate 6 should be equal (C = D).
3) Adjusting the inclination
1. Turn the handwheel and set it to the position where feed rock crank
arm shaft 4 can be observed from the hole in the machine bed.
2. Loosen setscrew 5 in the feed rock crank arm shaft.
3. Turn feed rock crank arm shaft 4 using a screwdriver from the
hole in the machine bed and adjust the inclination of feed dog
2.
4. Tighten setscrew 5 in the feed rock crank arm shaft at the position
where the feed dog is parallel to throat plate 6 when top surface
of throat plate 6 is aligned with that of feed dog 2 when feed
dog 2 descends below the throat plate (direction of d).
5. Turn the handwheel by hand and check the inclination of feed
dog 2 after the adjustment.
(Caution) When the adjustment value at the time of delivery
from the factory is changed, be sure to turn the
handwheel by hand and check the inclination of
feed dog 2 before operation.
™ To incline the feed dog with its
front up is effective to prevent
puckering. To incline the feed
dog with its front down reduces
fabric yarn breakage of knit
materials.
