apply a dror or two of oil at B6 and A6, Fig. 4 where the r,resser bar
Fig. 4. End View (Face Plate Removed lo Show Oiling Points)
passes through its bushings, also at JJ and QQ, Fig. 4, where the needle
bar passes through its bushings.
NOTE-After the machine has been running at a moderate speed for
obout five minutes, it should be stopped ond allowed to stand idle for o
few rninutes The oil in the reservoir should then he checked and oil
should be odded, when necessary, to bring it to the oil level mark, YY,
Fig. 3.

To
Regulate
Needle-Avoiding
Motion of
looper
G3
The
needle-avoiding
motion
of
the
looper
should
be
regulated
so
that
the
looper
will
pass as close
as
possible
to
the
needles
without
actually
touching
them.

To
adjust,
loosen
the
three
set screws

only
two
of
which
are
visible
in
Fig. 22,
and
turn
the
eccentric
G3
until
the
required
amount
of
needle-
avoiding
motion
has
been
obtained,
then
securely
tighten
the
three
set
screws
Y2.
NOTE-This
adjustment
will
impart
the
required
motion
to
the
looper,
but
it
is
also
necessary
to
center
this
movement
with
regard
to
the
needles,
by
rnoving
the
looper

inward
or
outward
after
loosening
the

at
any
time
during
its
motion.

NOTE-For
some threads
it
will be necessary to set the
auxiliary

at
a height different from that required
by
others,
owing
to the
differences
in
finish, twist, elasticity, etc.

TO ADJUST THE THREAD TENSION RELEASER
See Fig. 26
The thread tension releaser must release tension on the needle threads
and the covering thread when the presser foot is raised.
Fig. 26. Adjust Thread Tension Releaser
In case the tension releaser does not properly release the threads,
loosen the set screw J3 and turn the shalt H3 over to the left until correct
adjustment is obtained, then securely tighten set screw J3.
TO REGULATE HEIGHT OF PRESSER BAR LIFT
When the presser foot is raised to its highest position, the top of the
presser bar lifting bracket D3, Fig. 27, should be stopped against the
lower end of the presser bar bushing when the top surface of the presser

foot is just below the thread-laying finger M, as shown in Fig. 28, to pre-
vent the presser" foot from strik:ng and damaging the thread-laying finger.
To adjust, loosen set screw C3, Fig. 27, and move the bracket up or
down to produce the correct presser bar lift, then tighten set screw C3.
23
TO SET THE FEED DOG AT CORRECT HEIGHT
See Fig. 29
When the feed dog is at its highest position, approximately the full
depth of the feed dog teeth should project through the slots in the throat
plate. The height of the feed dog is determined by the stop screw N3,
which, with the feed dog removed, may be turned up or down as required.
The feed dog should always rest upon the stop screw N3.
TO SET THE FEED DOG AND THE GATHERING FEED WITH
RELATION TO THE SLOTS IN THE THROAT PLATE
See Fig. 29
To Centralize the Feed Dog and the Gathering Feed in the Throat
Plate Slots, first
release the actuating lever V2. Then the rear feed wil I
not
function as a gathering feed, but will function as a feeding unit. The
feeding action of this unit must then be equi-distant from both ends of
the slots. To adjust, loosen clamping screw X3 cmd turn the eccentric
hinge pin M3 until the feeding oction is centroli7ed as stoled obove, then
securely tighten clamping screw X3.
