MAINTENANCE
INSTRUCTIONS
INTRODUCTION
All
U.S.
BLIND
STITCH
machines
are
designed
for longlifeand trouble-free performance.
When
installed and lubricated in accordance with the INSTALLATION AND OPERATING INSTRUC
TIONS,
onlythe
minimum
maintenance
normally
associated
withindustrial
sewing
machines
will
be required. These maintenance requirements willgenerally be confined to the four locations des
cribed
below,
at
which
wear
may
beexpected after extended
use.
When
suchweardoesoccur, the
worn
part
may
be readily replaced by following
the
appropriate instructions.
For
ease
of
installa
tion, and to
insure
satisfactory
service,
it is
essential
that only
genuine
U.S.
BLIND
STITCH
parts
and
needles
are
used.
They are the only parts
designed
specifically for the machine, with the built-
in longlife and excellent wearing characteristicstypical of the U. S.
BLIND
STITCH
machine.
A.
REPLACING
THE
LOOPER
1.
Should
it
become
necessary
to replace the looper (item "B" in
Figure
6),
loosen the looper clamp screw (item
"A"
in Figure 6) and remove the old
looper.
Because
of the
precise
fit of the looper in the looper rod it may be
necessary to
exert
amoderate
amount
of
force to pull the looper out. Insert
the
new
looperinto the endof the rod asfar asit
will
go
before
bottoming on
the
looper
shoulder.
2.
Any
timea looperis
moved
or
changed,
recheck
the looper
timing
and
reset
if necessary. Proper looper timing is absolutely essential for correct stitch
formation.
As
described
in detail
below,
aproperly timedlooper
will
pass
over the needle in the correct position to pick up the loop, and also clear the
chain-off
pin,
feeder,
looper
slot,
and
needle.
The
first
check
pointfor
timing
the looperisat the position
where
the looper
picks
the threadloop off the
needle
during
the
needle
returnstroke.
Referring
to
Figure
7, (Point"C"),
the long prong of the looper should passover and just clear the scarf of the
needle,
approximately 3/32"
(2.4mm)
behind
the end of the
needle
eye.
At
the same time, the short prong of the looper should passover the needle with
about 1/64" (.406mm) clearance, and must be so set that it also clears the
chain-off pin (item
"D"
in Figure 7).
From the library of: Superior Sewing Machine & Supply LLC
4.
To
adjust
the
looper
so
that
the
timing
checks
out
as
noted
in
paragraph
2,
It
may
be
rotated
within
its
clamp
by
a
limited
amount.
This
adjustment
should
be
made
with
the
looper
clamp
screw
(item
"A"
in
Figure
6)
loosened
and
the
looper
bottomed
against
its
shoulder.
Do
not
move
the
looper
in
or
out,
and
do
not
attempt
to
force
the
looper
to
turn
beyond
the
limited
amount
of
travel
available.
If
the
adjustment
described
in
paragraph
3
is
insufficient
to
provide
the
correct
timing,
it
will
be
necessary
to
turn
the
looper
rod
(item
"E"
in
Figure
6)
itself.
TOs
may
be
accomplished
by
loosening
with
looper
rod
clamp
screw
(item
"C"
m
Figure
6).
The
rod
is
then
free
to
turn
in
the
looper
rod
fork
(item
"D"
in
Figure
6).
It
will
normally
be
necessary
to
make
only
a
very
small
adjustment
m
order
to
get
the
looper
into
the
correct
rotational
position
for
proper
timing.
If,
for
any
reason,
the
rod
has
been
removed
or
the
basic
setting
of
the
looper
rod
has
been
disturbed
by
a
large
amount,
it
may
be
reset
by
noting
that
the
distance
from
the
center
of
the
looper
rod
fork
pin
(item
"F"
in
Figure
6)
to
the
rear
face
of
the
looper
rod
ball
(item
"G"
in
Figure
6)
is
normally
4&
3/32
inches
(104mm)
(refer
to
Figure
6).
If
the
rod
is
set
to
this
dimension
then
only
minor
adjustment
will
be
required
to
bring
the
looper
into
the
correct
timing
position.
Note
that
this
dimension
is
merely
a
guide
to
assist
in
setting
a
rod
and
vanations maybeexpected
from
machine
to
machine.
If,
after
completing
the
above
adjustments,
it
is
found
that
the
looper
is
either
too
low
or
too
high,
it
will
be
necessary
to
adjust
the
eccentric
stud.
First
loosen
the
two
set
screws
(item
"A"
in
Figure
7).
Place
a
wide
blade
screwdriver
in
the
slot
of
the
eccentric
stud
(item
"B"
in
Figure
7)
and,
using
a
slight
turning
motion,
raise
or
lower
the
looper
as
required.
Once
the
proper
height
is
established,
check
to
see
whether
the
looper
must
be
moved
to
the
left
or
to
the
right
prior
to
retight-
ening
the
eccentric
block
set
screws.
If
such
a
movement
is
required,
it
may
be
ob
tained
by
lightly
tapping
the
eccentric
block
in
the
correct
direction
with
the
handle
of
ascrewdriver.

6. Once the looper is timed with respect to the needle as outlined in paragraphs 2
thru
5above, slowly
turn
the
handwheel
in a
direction
away
from
the
operator,
until the looper approaches the edge
of
the looper slot. (Point
"C*
in Figure 8)
in the presserfoot. At this point make sure the small prong
of
the looper clears
this edge. If it does not clear, adjust the eccentric block as outlined in paragraph
5
until
the
interference
is
eliminated.
6A. If timing
of
looper still proves difficult, its possible
that
looper sweep required
adjustment. If looper is too close to chain
off
pin and also, too close to needle
guide on opposite position,
the
looper
sweep is
too
short.
If looper on pick up stroke, is
too
far to right
of
chain
off
pin and
too
close
to
needle rest
at
left
of
presserfoot,
the
looper
sweep is
too
wide.
For
adjustment, refer to insert illustration (Figure 6). To widen looper sweep,
flex or bend looper crank in direction of arrow
"H".
To shorten looper sweep, flex or bend looper crank in direction
of
arrow
"J".
Both adjustments should be gradual and sweep checked frequently.
7. Continue turning the handwheel away from the operator until
the
point
of
the
needle starts to
enter
the area in between the looper prongs. (Refer to Point
"D"
in Figure 8). If the needle strikes the crotch
of
the looper, the looper has general
ly been set too far forward. Check to see if the looper has been inserted into the
clamp as far as it will go. It should be inserted until the shoulder on the looper
is stopped on the clamp. If this check is satisfactory, recheck the distance from
the center
of
the looper rod fork pin to the rear face
of
the looper rod ball. Refer
to
paragraph 4
and
reset
if
necessary. If
neither
of
the
above
two
measures
cor
rects the problem, it is possible
that
the needle lever may be set too low and
required
adjustment.

8.
Once
clearance
is
established
between
the
needle
and
the
looper
crotch,
continue turning the handwheel away from the operator until the needle
passes
between
thelooper
prongs,
clearing
both thelongand the short
prong.
If
difficulty
is
experienced
at thispoint,it
may
be
necessary
to
modify
some
of the
previous
adjustments to the eccentric blockor the looperrod
length.
If thisisdone,recheck the
previous
pointsto
insure
that a position isestab
lished which will satisfy all
of
the clearance conditions.
9. After
all
the
necessary
adjustments
have
been
made,
tighten
all
set
screws
and
the locknut and
recheck
allthe adjustment points.
Referring
to
Figure
9, the
loopershould nowclearthe chain-offpin ("D"), feeder("E"), looper slot
("F"), needle, and
pass
overthe needlein the correct position to pick up the
loop.
B.
REPLACING
THE
NEEDLE
GUIDE
1. Afterconsiderable
service,
it maybeexpected that the
wearing
actionof the
needle willcause a sharp edgedgroove to form on the needle guide(item
"G"
in
Figure
9).
This condition can cause thread breakageand uneven penetration.
When
this
happens
the
guide
should
be
replaced.
The
needle
guide
was
specifically
design
ed as a readily replaceablewearplate to prevent
damage
to the presserfoot from
the
action
of
the
needle.
2.
Loosen
the needleguideattachingscrew(item "A" in Figure9) and
remove
the
worn needle guide. Clear
out
any lint or dirt
that
may have accumulated under
the old guideand insert the new guide. Insure that the new guide is seated flush
with the top and sideof the presserfootand then retighten the attaching
screw.
Slowly
turn the handwheel in the direction away from the operator and check
to insure
that
the new guide fits properly
under
the needle and
that
no
inter
ference has been introduced between the guide and the looper.
REPLACING
THE
SHOE
1. The shoe, (item
"E"
in Figure 8), also known as a cloth retainer, normally will
not
required replacement. However, in the event
of
wear due to the particular
fabricsbeingused, or if the shoe or springsuffers any damage,they may be
readily
replaced.
2. The first step is to
remove
the complete front guideassembly by unscrewing the
front guide holder attaching screw (item
"A"
in Figure 8). Next loosen the shoe
pin and the shoe eccentric barrel lock screws, (item
"B"
Figure 8), and slide
out
the shoe pin (item "F"), shoe and retaining spring (item "G")- Beforeremoving
these components it is advisable to note the manner in which the springis
assem
bled so that it may be reinstalled in the same way.

3.
When
replacing
an
old
shoe,
make
sure
that the
replacement
shoe
properly
fits
the
pin without
binding
and without
excessive
looseness.
In the
event
that the pin has
worn and does not fit the newshoe properly,it shouldbe replaced at the sametime
asthe
shoe-pin.
After
replacing
the
shoe,
shoe
pin
spring
into
shoe
eccentric
barrel,
re-
tighten screws (item
"B"
Figure 8), and check to insure that the center
of
the shoe
is lined up with the center of the rib. Also insure that the shoe clears both sides
of
the
opening
of
the presserfoot.
4. Inand out position of shoe
should
nowbe
checked.
Forlight
fabrics,
shoe
should
be as closeto needle as possible. For heavy fabrics with seam,shoe should be set
back as far as possible from needle. To move shoe in and
out
turn
eccentric barrel
(item"I"
Figure
8), Afterthe correctlocation isestablished, besure to tighten
screws,
(item
"B"
Figure 8).
4A.
An
additionalshoeadjustment isalsopossible. Theheight of the shoe can now be
controlled, (item
"H"
in Figure8). Thisis a tapered pin and position can be ad
justed so that the shoe, whenever required, can be controlled as far as elevation is
concerned. By
moving
the tapered pin in or out the shoe can be kept from pressing
downon some
fabrics
whichrequire little, if any shoe pressure. By
having
this
control, it sometimes
will
aid in penetration of difficult fabrics. The normal posi
tion of the shoe, when set properly on most fabrics, is
that
the shoe will show move
ment
on
the
penetration
cycle on one ply
of
fabric.
5.
REPLACING
THE
CHAIN
OFF
PIN
1. After considerable service,it may become necessary to replace the chain
off
pin,
(Item
"D"
in Figure 7).
2. Remove the chain
off
pin attaching screw and remove the chain
off
pin, clean
out
any lint or dirt
that
may have accumulated. Attach the new chain
off
pin,
using the screw previously removed. Insure that the chain
off
pin is against the
side and forward edge
of
the slot in the presserfoot, and then tighten the screw.

D. REPLACING
THE
FEEDER
1.
In
the
event
that
the
machine
develops
difficulty
by
failing
to
properly
feed
the
work,
a
worn
feeder
is
frequently
found
to
be
the
cause.
After
considerable
service,
especially
with
certain
hard
fabrics,
the
feeder
teeth
have
a
tendency
to
become
dull,
and
the
feeder
should
be
replaced.
In
order
to
remove
the
old
feeder,
remove
the
front
feeder
attaching
screw
(item
"B"in
Figure
9)
and
loosen
the
rear
feeder
attaching
screw
(item
"C"in
Figure
9).
The
old
feeder
may
then
be
slid
outof
place.
Insert
the
new
feeder
under
the
rear
screw
and
replace
the
front
screw.
2.
Before
tightening
the
attaching
screws
check
to
see
that
the
feeder
is
set
to the
proper
depth.
Referring
to
Figure
10
this
should
be
approximately
1/32"
(.795mm)
below
and
parallel
to
the
bottom
of
the
presserfoot
for
all
light
and
medium
weight
fabrics.
For
heavy
fabrics,
the
setting
should
be
approximately
1/16"
(1.59mm)
below
and
parallel
to the
bottom
ofthe
presserfoot.
These
dimensions
are
intended
as
guides
and
may
be
modified
as
required
by
the
specific
fabrics.
Once
the
proper
depth
is
established,
rotate
the
hand
wheel
slowly
in
a
direction
away
from
the
oper
ator
and
check
to
insure
that
the
feeder
clears
the
looper
(see
Figure
9,
Point
"H")
and
also
clears
both
sides
of
the
feeder
slot
in
the
presserfoot.
Firmly
tighten
feeder
attaching
screws
(Figure
9,
