1)Loosen nut
②
As you tum presser spring
regulator
①
clock wise ( in direction A), the
presser foot pressure will be increased.
2)As you turn the presser spring regulator
counterclock wise (in direction B ),the pressure
will be decreased.
3)After adjustment ,tighten nut
②
4)For general fabrics,the standard height of the
presser spring regulator is 29 to 30 mm (5kg).
1)To obtain the standard feed timing align
setscrew A on feed eccentric cam
①
with
setscrew B on main shaft thrust collar
②
.
2)To make adjustment,loosen two setscrews
③
to release the feed eccentric cam , properly
position the eccentri cam. Then retighten the
setscrews.
3)To advance the feed timing in order to
prevent uneven material feed,move the feed
eccentric cam in the direction of the arrow.
4)To delay the feed timing in order to increase stitch tightness, move the feed eccentric cam in the
opposit direction for the arrow.
5)Be careful not to move the feed eccentric cam too far,or else needle breakage may result.
l)The standard tilt(horizontal)of the feed dog is
obtained when marker dot Aon the feed bar
shaft is aligned with marker dot B on feed
rocker
①
2)To tilt the feed dog with its front up in order
to prevent puckering,loosen the setscrew, and
turn the feed bar shaft 90 dearees in the
direction of the arrow. using a screw driver.
3)To tiltt the feed dog with its front down in
order to prevent uneven material feed,turn the feed bar shaft 90 degrees in the opposite direction from
the arrow
(Precaution)
Whenever the feed dog tilt is adjusted,the feed dog height will be changed.So,it is
necessary to check the feed dog height aftertilt adjustment.
