TO
REGULATE
PRESSURE
OF
PRESSER
FOOT
ON
MATERIAL
Correct
presser
foot
pressure
helps
feed
work
effi
ciently. You con
regulate
amount
of
pressure
exerted,
by
means
of
screw
on
top
of
arm,
as
shown
in Fig. 26.
Pressure on material should be as light as possible,
while sufficient to insure correct
feeding.
To
increase
pressure
turn
this
screw
downward
(clockwise).
To
reduce
pressure
turn
this
screw
upward
(anti
clockwise).
Do
not
completely
release
pressure
on
presser
foot
otherwise
the
ball
bearing
on
the
top
of
the
presser
bar
may
be
displaced.
Pressure
is correct
when
work
moves
steadily
and
smoothly
without
stalling.

TO
REVERSE
THE
FEED
ON
MACHINES
451K45
and
451K145
(See instructions in Fig. 28)
Simply
depress
feed-reversing lever shown in
Fig.
28,
as
far
as
it will
go.
Feeding in reverse continues only as long as lever
is held in depressed position.
Forward feeding is resumed upon release of lever.
Direction of feed can be reversed at any point in a
seam
while machine is in operation, without disturb
ing the work.
Back
tacking is therefore readily
accom
plished and ends of seams are easily fastened.
For adjustment of stop pin, shown in Fig. 28, see
