1) When sewing heavy-weight materials, move thread
guide 0 to the left (in direction 0) to increase the
length of thread pulled out by the thread take-up.
2) When sewing light-weight materials, move thread
guide 0 to the right (in direction 0) to decrease
the length of thread pulled out by the thread take-
up.
3) Normally, thread guide 0 is positioned in a way that
markerline C9 is aligned with thecenterof the screw.

1) The standard tilt {horizontal) of the feed dog is obtained when marker dot0 on the feed bar shaft is
aligned with marker dot
4D on feed rocker 0. {The marker dot 4D inclines forward the feed rocker
shaft by
goo, as standard).
2) To tilt the feed dog with its front up in
order to prevent puckering, loosen the setscrew, and turn the
feed barshaft
goo in the direction of the arrow, using a screwdriver.
3) To tilt the feed dog with its front down in order to prevent uneven material feed, turn the feed bar
shaft
goo in the opposite direction from the arrow.
,-----------------------------------,
I ~ Whenever the feed dog tilt Is adjusted, the feed dog height will be changed. So, it is I

the arrow or opposite direction of the arrow, and firmly tighten the screws.
2) Forthe standard adjustment, adjust so that the top surface of feed dog and the top end of needle

the throat plate.
3) To advance the feed timing in order to prevent uneven material feed, move the feed eccentriccam
