The t o p feed amount varies when the bottom feed amount (stitch
length) is changed by the pushbutton switch.
(Refer t o the

Instruction Book for how t o adjust
the stitch length.)
When the maximum top differential feed ratio(l:2.8(2514N),
1:
18 (2516N)
or more) is used at the maximum stitch length cut
t h e rear end of the t o p feed dog. This is necessary because the
rear end of the top feed dog may come into contact with t h e rear
end of t h e slot in the presser foot when the top feed dog is in its
backmost position.
(Note) In the MOJ-2500N model, when the stitch length and
the top differential feed ratio are changed, be sure that a
clearance of 1 mm or more i s produced between the slot
in presser foot and the end of top feed dog
@
when the top feed dog i s in the front end position. I f the
clearance is less than 1 mm, cut the end of the top feed
dog by
3
mm at a maximum.
