1. INTRODUCTION
A wirestitcher,like any othermachine, will give
satisfactory results toits owneronly if properly
installed, regularly lubricated, intelligentlyadjusted,
and carefullymaintained.Movingpartswillwear in
time and requirereplacement,whileothers may
break through accident. Trained service menare
available butnot always tobehadata moment's
notice, anda knowledgeof thefunctionsof themore
importantparts ofa stitcher is thereforemost
desirable for everypersonresponsible forits
operation, in order to knowwhat todoin case of
trouble.
We have,therefore,gatheredtogether the com-
bined experience ofour engineers and service men
and haveattempted to present the information ina
manner that will make it quicklyavailable and readily
understood.
We wouldurge,however, inany case of serious
difficultythat you notify our nearestsalesoffice,
sendingsamples ofthe defectivework and describ-
ingthe trouble in detail, soasto obtain the benefit of
theirexperience in arriving atthe propersolution. Be
sure to report the serialnumber and model ofthe
machinewhencorresponding in regard to equip-
ment, so that itmaybe identifiedquickly.
2. INSTALLATION
(See charts and parts lists for locations and
names of parts referred to.)
Any machine canbe seriouslydamagedduring its
installation ifitisnot properly setup; therefore, we
recommendcloseadherence tothe following
procedure:
(a) After uncrating machine, examinecarefully
for any breakage in transit. If such be found, donot
attempt torun machine but report at once tothe
sellingagent. Ifour service manis present, lethim
examine machine and thenreport tothe manufac-
turer.
(b)See thatmotor is free to revolve when large
pulley or flywheel is turned by hand. If tight, clutch is
perhaps engaged, in whichcaseshaft will turn also.
Turningpulley or flywheel one revolution will
release clutch.
(c) Examinenameplate on motor andsee that its
specifications arethe same as those ofthe power to
be used. If not, donot attempt to operate the
machine.
(d) Place the machine ona level floor, using
shims underbase if necessary to prevent any
movement or rocking.
(e) Lowerclincher to at least 2" below the stitcher
head, by means of adjustingsleeve on posttype
stitcher, orclincherbracketadjustingscrewon head
mountedclincherbracketstitcher or clincher arm
adjustingscrew or bolt onarm typestitcher.
(f) Be sure that the machine isoiledthoroughlyat
all pointsbeforeoperating.
Run a little oilon coil of wire, which helps to
lubricate wirefeedtubes and also the formers and
driver, which are tight-fittingwhennew. Tiea piece
of clothtemporarilyaround the wireabove thetop
end OT tne upperwire Teed tube to remove dirt and
excess oiland thuspreventsoiling the work.
(g) Connectmotorcord to poweroutlet and start
motor. See that it runsfreely,without undue noise,

and that the largepulley rotates clockwiseasviewed
from the front ofthe machine.Should it rotate
counter-clockwise,motor wiring should bere-
connected byan electrician in order to reverse
direction of rotation.
(h) Pushdownfootswitchtreadle and thusstart
machineoperating,starting and stoppingseveral
times.
(i) Stopmotor, and with connectinglink arm
pulleddown,turnpulley by handuntil driver isat
lowest point.
(j) Withdriver in lowestposition and work tobe
stitched undersame,raiseclincherpost,bracket, or
arm, untilwork is heldfirmly.Thenlockpost,
bracket, or arm, in position.
.(k) Place a spool of wire of proper size onthe
spoolholder, the wireleading tothe left from topof
spool,thentighten spool-holderspindlejam nut just
enough to give a slightdrag tothe rotation of spool
and prevent the wire uncoiling.
If itistoo tight, the wire will bind and catch
between the coils and thus may causeuneven staple
legs. Iftoo loose, the spool may unwind,causing
snags inthe wire.
Cut binding wires on wire coil and bendsame
back overedge of spool, holding free endof wire in
the hand to preventunwinding and tangling. Cutoff
bent and twisted endofthe wire,thenstraighten out
about 6".Theendofthe wire tobe inserted in
machinemust be just as straight as possible.
Openwirefeedgears by raisingidlerfeedgear
throwouthandle and insert endof wirethrough eye
on upper endofthe spring wire guide.Enter the end
of the wireinto the upper wiretube,pushdown
between the wirefeedgears,thenthrough the lower
wiretube and between wire straightener rolls.Push
it into the hole inthe stationarycutter,raising the
endofthe wireslightly if necessary for proper
entrance, thenturn down the idlerfeedgear
throwouthandle,thusengaging the feedgears.
WARNING:—NEVER OPERATEMACHINEWITH
WIRE FEEDING ANDNO MATERIAL ABOVE
CLINCHER.SERIOUSDAMAGE MAY RESULT.
(I) Startmotor and drive a few stitchesinto
materialand, if necessary,adjustclincherheight to
get desiredtightness of clinching. See instructions
for adjustingclincher.
(m) Adjust for properlength of wire by loosening
lockscrew and movingwirefeedguardcasting to
rightor left alonggaugemarks on upper part of head
casting.Moving to leftreduceswiredrawwhile
moving to rightincreases it. When setat mark"0",
head will draw one inch of wire and eachmark
indicates an additional
1/8"
in length.Whenproper
length of wire is beingdrawn,tightenlockscrew in
placefirmly.
(n) Driveseveralrows of stitchesintomaterial to
be used,examiningcrown and legs for proper
appearance. Ifnot satisfactory,adjustmachine in
accordancewithdirectionsgivenhereafter.
NOTE:—When changinglength of wiredraw, the
firststitch driven, and perhaps the second, will beof
the previouslyused length since itis formedfrom a
piece of wirealready cutand held inthe anvil. The
third stitch, however, will beofthenew length.

3. ADJUSTMENT AND MAINTENANCE
The followingparagraphscoverbriefly the various
functions and operatingparts ofa stitcher and also
give the propermethods of adjustment and replace-
ment of parts.
Every Stitchershould be oileddaily, andif
machine isin constantuse, twicedaily.Theoil holes
and cups are easilyfound on stitcherhead and body.
A heaviertype ofoil should be used forthe former
and drivebar. A lightmachine oil should be usedfor
remainder of head.
CAM LUBRICATING INSTRUCTIONS:-Trip
clutch and rotatedrivepulleymanually, if necessary,
in direction indicated by arrow on pulley until grease
fitting oncamis alignedwithhole in lubricating
cover unitlocated in body or headcasing.
Whenfitting is visible thru hole in lubricating
cover unit, lubricant canbe appliedwith a grease
guntofit alemitehydraulicfitting(straighttype).
Itis recommendedthat thecambe greasedonce
monthlywithHarris Moly-Lube #2 (high
temperature) lubricant or equivalent.
WARNING:—EXCESSIVE AMOUNT OF LUBRI-
CANT MAY BLEEDCAUSINGDAMAGE TO WORK
BEING STITCHED.
(a) Clutch
Clutchshould be oiledfrequentlywithlight
machineoil.Never let clutch run dry. To oil,turn
collar atendof shaft until oil hole is exposed. Puta
few drops ofoil intobrakebandoccasionally.
If the clutch hesitates on picking up, turnlower \
brake adjustingscrew inor clockwiseabout
1/4
to V2
turn, or untilclutchpicks up.Ifthe clutchrepeats,
the lowerbrakeadjustingscrewshould be backed
out untilclutchdoes not repeat. Be sure,however,
that the BRAKEBAND IS FREEwhen the clutch isin
operation or engaged.
Clean outthe ClutchRing and Flywheelwith
kerosene orany cleaningsolvent. Itisnot necessary
to take the Clutchout.Squirt the cleaningfluidinto
the Flywheel and ClutchRing andrunthe machine
fora few moments,continuouslystarting and
stopping.
NOTE:—Proper action of clutch and brake isas
follows:
Whenclutchengages,brakebandshould be free
and whenclutch is disengaged,brakebandshould
be tight and clutchshould be free.
Whenclutchringwearsbeyond point of contact,
replacepins #2347 withpins#2347A.
The followingfigureswillidentifyexpandingpins
referred to:
No. 2347 pinis .156"thick
No. 2347A pinis .166"thick
Thickness is determined by measuring thepin
from the flat side tothe oppositeroundsidewith a
micrometer.
NOTE:—When replacingrings in clutch unit, the
heads ofthe expanding pins forthe brakering and
clutchringmust be facingeachother.
(b) Clincher
The clinchermust be lined up with the staple as

closely as possible to insuremaximum ease of
penetrationthroughwork bythe staple, as well as to
clinchstapleproperly.

iy.
(c) Stitching Wire
When stitching metal ithas beenfound that #18
wire is bestsuited tothe majority of work.This wire
canbehadin various degrees of hardness or temper,
such as#18 Bookbinderswire,which isthe softest,
#18-230,#18-260,#18-290 and #18-330.
It is impossibletogivethe exact thickness of metal
which a giventemper of wirewillpenetrate.
Roughly,Bookbinderswirewillpenetrate a single
thickness of .020softsteel; #18-230, two thicknesses
of .020(total .040); #18-260, two thicknesses of .040
(total.080);#18-290, one thickness of .060plus.030
(total .090);#18-330 two thicknesses of .060(total
.120).
If the metal istoo hard,there maybe trouble in
stitching so great a thickness; onthe otherhand, if
the metal is soft, the thickness maybe increased.
Whenstitching a softmateriallikefibre or rubber
to metal, especially if thismaterial is thick,there may
be trouble in penetrating the metal dueto lack of
support forthe wire inthe softmaterial. For this
purpose, the #18-290wire may help, in which case
special spool holder equipmentwill be required.
Itis best tousethe softestwirethatwillpenetrate
the worksafely, asthe harderwirewillcausemore
wear onthe machine.
(d) WARNING:—IN OPERATING A STITCHER,
BE CAREFUL NOTOT DRIVE ONE STITCH OVER
ANOTHER, AS THIS MAY BREAK THE DRIVER
TIPS.
DONOT OPERATE THE STITCHERWITH WIRE
FEED ONBUT WITHOUTMATERIALBETWEEN
DRIVER AND CLINCHER.
IFA PIECE OF WIREGETSCAUGHT INTHE
GRIPPER OR FORMER OR SHOE,STOP THE
MACHINE AND REMOVECAREFULLYBEFORE
ATTEMPTING TO STITCH AGAIN.
