MOUNTING MACHINE
1. Fasten machine to table using felt pad. Tighten
screws evenly, turning each a little
at a time.
a. When an individual motor and clutch unit
is employed, it is recommended that the
motor be rated at 'h HP and 1725j1750
RPM. On all standard models, use a 31f2"
outside diameter pulley. On models in-
tended for alteration, use a 21f2" outside
diameter pulley.
b. When the machine is mounted on a power
table, a 4" pulley should be used. If pos-
sible, when using such stands,
the machine
should
be mounted TO AVOID CROSS-
ING THE
BELT.
c. The maximum machine speed recommend-
ed for any installation is 3000 RPM, unless
otherwise specified.
2. The handwheel's direction of rotation is away
from
the operator. It rotates in a clockwise
direction when looking at the face of the
wheel pulley, as shown by the arrow.
3. Either V-belting or round leather belting may
be used. Excessive tension of belt will cause
over-heating
and freezing of bearing at hand-
wheel.

ADJUSTING RIB TO NEEDLE
THE MACHINE SHOULD IE CHECKED TO INSURE CORRECT
NEEDLE SETTING TO PREVENT DAMAGE TO NEEDLES.
1. Press knee lifter to depress feed frome.
2. Turn hand wheel CLOCKWISE until eye of needle is at slot in
presser foot shoe (Fig. 1 ).
3. Slowly release knee lifter. The rib should JUST TOUCH THE
NEEDLE (Fig. 2).
4. If rib is pressing up against needle (Fig. 3), turn dial toward
"LESS" until rib just touches needle.
5. If rib is away from needle (Fig. 4), turn dial toward "MORE" until
rib just touches needle.
6. When needle just touches rib (Fig. 2), machine is set to test.
7. To test machine, when ratio is set 2 to 1 ratio-take sing~ layer
of material, place in machine and turn machine by hand. If machihe
catches once, then does not catch on next stroke, machine
is
ready to work.
8. Keep dialing "MORE" or "LESS" until above results are obtained
on
silk or any thin goods.
9. On heavy goods, it should catch or:l each stroke of needle.
1 O. You are now ready to thread machine. Refer to 'threoding
instructions.
FIG. 4
IMPORTANT:
Place o piece of thin sample material in machine. Set stitch
ratio on 2-to-1. Turn hand wheel clockwise by hand so that
needle catches on one stroke and skips a stitch on second .stroke.
ON THE SKIP STROKE, stop when the eye of the needle is at
the rib (fig. I). At this point, the gop between the Compen-
sating Skip Stitch Screw (fig. 5, Al and the Push
Rod IBl
should be .018 ( Cl. On the absence of o gauge, .018 is about
5 times the thickness of average letterhead paper.) This
ad-
justment is made by loosening Lock Nut (f) , adjusting screw
lA) so gap at !Cl is .018. Keep screw in place with screw-
driver and secure Lock Nut.
Once this
is done, a similar adjustment on Feed Frome Limit
Safety Screw
IE) should be made. Loosen Lock Nut !Dl,
adjust Safety Screw IE) so that gap (Gl between Screw IE)
and Main Frome of machine is .018. Hold Screw in place with
screwdriver and secure Lock Nut. THIS ADJUSTMENT IS TO
PREVENT OPERATOR FROM MISTAKENLY ADJUSTING RIB
TOO HIGH WITH "MORE/LESS" DIAL CAUSING NEEDLE TO
STRIKE RIB AND BREAK.

HOW TO SEW
1. Turn hand wheel slowly clockwise until needle
reaches high point (A).
2. With hands 12 inches or so aport (Fig. 1) hold
hem firmly. Depress knee lifter, pfoce hem in
machine parallel with, and up under presser
foot.(D)
3. Place edge of hem in slot of shoe (B) and at
edge of gauge (C).
4. Start sewing. IMPORTANT: Keep edge of
hem lightly, but firmly against gauge, keep
material parallel to gauge by KEEPING EYE~
ON GAUGE ONLY ... NOT ON NEEDLE
OR SEWING.
5. To remove ... make sure needle is again at
high point. Depress knee lifter and pull work
AWAY FROM YOU, straight back to break
thread.
IMPORT ANT-DO NOT TUG MATERIAL BACK
AND FORTH OR IT WILL UNRAVEL THE STITCH.
START SEWING
1. On thin goods or ribbon cloth guide Fig. 1,{C).
should be set almost at extreme right side of
machine and should obtain results shown in
Fig. 2. (F).
2. For heavier goods, bring cloth guide to the left
as necessary.
3. Do not pull material to help feeding, do. not
hold material back, just hold firm but lightly.
4. To remove finished work, MAKE SURE
NEEDLE IS AT HIGH POINT FREE OF
GARMENT.
TENSION
If material puckers, loosen tension.
If thread is loose, make sure thread is between
tension, discs then tighten accordingly. Do not
hesitate to turn tension nut several times as needed.
On thin goods, a light tension is required. On
heavier goods, a tighter tension is necessary.
IMPORTANT: Unlike a regular machine, this ma-
chine requires very little tension.
UNRAVELING STITCH
To unravel the stitching, turn hand wheel CLOCK-
WISE to high point of needle. Continue clockwise
until thread is off looper. Then COUNTERCLOCK-
WISE to threading position.
Depress knee lifter and remove garment ... thread
will unravel.
To unravel stitch on finished garment, start where
stitching finished, break straight thread and unravel
backwards, NOT FROM DIRECTION OF SEWING.

(Fig. 2). Bring
Needle Point
back to right hand edge of Needle Guide. Then loosen screw
11
B", keeping
screwdriver in place. Move
Cam forward or backward until Rib is at the STOP
position, holding Needle in Position with handwheel while performing this operation. Tighten
Screw
"B". Test accuracy of adjustment by repeating operation outlined in first paragraph.
If still not correct, readjust by loosening screw "B" again, change angle of Cam slightly
forward or backward
as needed and retighten Screw "B". When adjusted satisfactorily, be
sure
to TIGHTEN BOTH SCREWS "A" & "B" before putting machine into operation.
TO SET Rl B SHAFT
When needle is in same position as in Fig. 1, loosen Screw in Fig. 3, and turn Rib
to desired position. Secure Screw. (See page 9 for closer detail of Rib Shaft if needed.)
NEEDLE STROKE
Turn Handwheel clockwise, bringing Nee~le to end of stroke at the right side. At this point,
the Needle tip should be 5/8" to 11/16" from the right side of Presserfoot opening (Fig. 4).
To attain this, loosen Eccentric Ball Screw
until Needle reaches desired position.
(Fig.
5) and turn Eccentric Boll
REGULATING LENGTH OF STITCH
loosen Screw (Fig.
5) in Stitch Regulating Collar and turn until desired number is by
Indicator Notch
in The larger the Pumber by the notch, the longer the stitch. The
smaller the number by the notch, the shorter the stitch. WHEN MAKING STITCH LONGER
