and
fixed knife
1.
Attaching fixed knife
1)
Attach
the
fixed knife
so
that
the
attached part parallels
the
rotary hook
base.
The movable knife
broadens
at
part®.
Make sure
the
fixed knife doesn't contact
it
at
this part.
2.
Knife timing
1)
While pushing
the
cam
lever 0 up
with
a finger, rotate
the
pulley @ in
the
direction
of
the
arrow.
When
the
knife
@)
begins
to
move,
the
pulley
will
become harder
to
turn.
At
this time, tighten
the
screw
of
the
24 J gear e I
fix
the
cam
CD
by hand
so
it
does
not
rotate, and
turn
the
pulley.
The
rotary hook
blade should be in
the
center
of
the rotary hook supporter@).
2)
Tighten
the
screw
of
the
24 J gear e
so
there
is
no backlash
of
the
cam
in
the
direction
of
the
lower
shaft. While pushing
the
cam
lever 0 up
with
a finger, rotate
the
pulley @again. When
the
knife
@)
begins
to
move,
the
blade in
the
rotary hook should be in
the
center
of
the
rotary hook supporter
@).
3.
Knife position
Loosen
the
screw & and adjust
the
knife
@)
position
so
that
its end projects 1 mm beyond
the
fixed
knife's tip.
After
thread trimming,
the
knife should be in this position.
If
the
knife does
not
stop
at
the
stop position,
the
upper shaft
will
be locked and
it
cannot make one
full
revolution. In
that
case,
move
the
knife
to
the
stop position by hand.

Knife and fixed knife
1)
With
a marker, color
the
back
of
the
knife
@)
and engage
it
with
the fixed knife
@)
manually.
Check
that
the
colored portion
is
shaved equally.
This
shows proper knife engagement.
2)
If
the
engagement
is
wrong, loosen
the
screw
@)
of
the
fixed knife
@)
and adjust
the
inclination
with
the
lower
set screw

NOTE:
The inclination
of
