Operation
Beforeoperatingthe machine,readtheseinstructions care-
fully. Familiarize yourself with all the functions and adjust-
ments of the machine.
CAUTION

supply may damage it.
2. Checkthatthemachinehasbeenlubricatedaccording
totheschedulelistedinRoutineMaintenance–Lubrica-
tion on page 5.
Note: Atthistime,carryoutthefullmonthlylubrication
scheduleon page5.
3. Make sure that the sharpener is in the locked position.
Todothis,pushintheturningknob(Figure2,F).While
depressingtheturningknob,turnthemachineoverafew
revolutions by hand to see if the knife reciprocates
easily. Iftheknifedoesnotmoveeasily,thesharpener
may be in the unlocked position.
4. To lock the sharpener in place, lift the release lever
(Figure2,D)andpressthesharpenerlever(Figure2,E)
toreleasethesharpener. Raisethesharpenerbracket
(Figure 2, S) by hand to lock it in place. Once the
sharpener is locked in place, you may disengage the
release lever and sharpener lever. Repeat step 3 to
ensurethat thesharpeneris nowlocked. Ifnot, repeat
this step.
5. Visually inspect the blade to ensure that the top of the
knifeisflushwiththeknifelockbolt(Figure7,1onpage
9)andthattheknifeisperpendiculartothebaseplate. If
you need to adjust the alignment of the blade, see
section Changing the Knife on page 9.
6. CheckthatthemotorswitchisintheOFFposition.Then
connecttheattachmentplugtotheterminalblockonthe
machine.
7. Hold the operating handle and turn on the machine.
Allow the blade to reach full speed. If the blade is
struggling, the sharpener is still not in the locked
position. Ifthisisthecase,turnoffthemachineanddo
thefollowing:
7.1 Withyourleft hand,straddlethe frontof thesharp-
enerwithfingers andthumb.
7.2 Press the bell crank release lever (Figure 2, H) to
disengagethesharpenermechanismfromthemotor.

Turning Off the Machine
When you have finished using your machine:
1. Position the power switch to off.
2. Makesuretheknifeguard/pressurefootisloweredtothe
baseplatebydepressingthepressurefootlever(Figure
2, R).
3. Disconnecttheattachmentplugfromthepowersource.
4. In cold weather, ensure that the machine is kept in a
warm place when not in use.
Routine Maintenance
WARNING
Always unplug the machine before performing mainte-
nance,adjustments, orrepairs.
WARNING
Afterservicing themachine, alwaysmake surethe plate
bolt nut is securely fastened (Figure 3, X on page 6)
beforeresuming cuttingoperation.
Care of the Machine
To ensure proper operation of your machine, carry out the
following procedures at the intervals indicated. If you use
yourmachine intensively, considerperformingthese proce-
duresmore often.
Daily
Remove the knife and clean the knife slides with the slot
cleaner (Figure 7, 2 on page 9) included with machine. To
prevent undue accumulation of lint, do NOT oil the plate
rollers. If the rollers stick, remove them from the plate and
wash them in cleaning solvent.
Starting the Machine
Ifyou havehadthe machineless thanonemonth orifit has
stoodidle forany lengthof time,turn themotoronandoff a
few times before running it continuously. This permits the
oil to warm up and flow easily into the close-fitting moving
parts.
CAUTION
Failure to warm up your machine adequately may dam-
agethe motor.
Making a Cut
WARNING
Failuretokeep hands,arms,andhairawayfromtheknife
area at all times may result in serious personal injury.
1. Bring the machine up to the material spread.
2. Raise the knife guard/pressure foot by depressing the
pressure foot lever (Figure 2, R) and lifting the knife
guard/pressure foot lifting handle (Figure 2, T). Raise
thepressurefootonlyenoughtoclearthematerialbeing
cut.
3. Turnonthemachine,allowthebladetoreachfullspeed,
andenterthe fabric.
4. Usingthepressurefootlever(Figure2,R)andtheknife
guard/pressurefootliftinghandle(Figure2,T),lowerthe
pressure foot so that it is slightly above the material
beingcut. Thiswillpreventthematerialfromreciprocat-
ing.
5. Begin cutting.
6. Whenyouarenotmakingacut,orwhenthemachineis
notinuse,keeptheknifeguard/pressurefootloweredto

Checking the Extreme Down Position of the Sharpener
The correct down position is with the tip of the knife at the
centerofthe beltontheshoe(Figure6,12). Thebeltshould
be in the most downward position, and the knife should be
in the most upward position. If the belts are too high, the
bottom point of the knife will not sharpen. If the belts are
too low, the bottom point of the knife will round off exces-
sively. If adjustment is necessary:
1. Raise the belt carrier to the up position.
2. Remove the plastic cap from the tube for the screw
shaft.
3. Insertapinthroughtheholeinthetube(Figure6,13)to
prevent the spacer (Figure 6, 14) from turning. Then
remove the locknut (Figure 6, 15).
The following step describes the correct procedure for
settingspaceradjustmentondifferentstrokemachines:
Note: Prior to beginning adjustment, be sure that the
spacer is threaded fully onto screw shaft.
Stroke Turns
1-1/8" 11
1-1/4" 9
1-1/2" 13
1-3/4" 8
Note: Each turn = 1/32"
4. Turn the spacer clockwise with wrench C6153 to raise
thebottom position,or turncounter-clockwiseto lower
the position.
Note: One turn in either direction adjusts the position
by 1/32".
5. Removethelocknut(Figure6,3).
6. InstallgaugeC189ontheexposedthreadedendofthe
pivotscrew(Figure6,7)andpresstheendofthegauge
against the side of the standard.
7. Holding this position, engage the opposite stabilizer
(Figure6,4)firmlyagainsttheside ofthestandardand
tighten the screws (Figure 6, 2).
8. Remove tool C189 and press the positioned stabilizer
(Figure 6, 4) against the side of the standard. Then
fastentheoppositestabilizer(Figure6,5)firmlyagainst
thestandard.
9. Re-engagethebackguide(Figure6,6)inloosecontact
with the back of the standard.
Checking the Sharpener Shoes
Theshoes shouldswingin andoutfreely withoutexcessive
up and down play. If adjustment is necessary, proceed as
follows:
1. Loosenthelocknuts(Figure6,3)andtightenthescrews
(Figure6,7)asrequired.
2. Check the clamping arm (Figure 6, 10) with the belt
carrierinthemostdownwardpositionandtheknifeinthe
mostupwardposition. The clampingarm shouldkeep
the sharpener shoe from moving in. If it fails to do so,
the serrations on the clamping arm are worn or the
sharpenershoe(Figure6,11)isworn.
3. Replacewornpart(s)asnecessary.

5. When the spacer is adjusted, use the pin to hold the
spacerinposition,reassemble,andtightenthelocknut
(Figure6,15).
6. Replace the plastic cap.
Checking the Stop Screw on the Sharpener Shoe
1. With new belts on the carrier, insert .010 feeler gauge
#141C1-27betweenthestopscrew(Figure6,8)andthe
knife. Ensurethat theclampingarm (Figure6,10) has
beenreleasedfrom thesharpenershoe(Figure 6,11).

and the knife.
2. If an adjustment is necessary, loosen the locknut
(Figure6,9). Adjustthesetscrewtotheproperspacing,
andre-tightenthe locknut.
Check the Width of the Bevel on the Knife
The bevel should be approximately 1/16" on both sides. If
it is not:
1. Install a new knife and new belts.
2. Color the bevel with a wax pencil.
3. Runthesharpenerupanddowntheknifeseveraltimes.
4. If an adjustment is required for Flex-Pad shoes, insert
