Figure 1 ADJUSTING THE LOOPER
For convenient access, remove the presser foot, throat plate and feed dog.
Insert the looper into the looper rocker. Set the looper so that the distance
from the center line of the needle to the point of the looper is 6.5 mm '" 1/4" in
the lowest position of needle bar just before moving upwards (Fig. 1). Then,
loosen the nut at the right side of looper rocker and the ball stud till the speci-
fied dimension is obtained. As the looper moves to the right, its point should
pass behind the needle as close as possible without contacting it. Adjustment
can be made by loosening the fastening screws of looper rocker and replacing
the looper rocker axially till this adjustment be obtained.
Figure 2
ADJUSTING THE SPREADER
The spreader should closely pass behind the looper and behind the nee-
dle so that its point just brushes, without deflecting them. Set the dis-
tance of 5mm '" 13/64" between speader and needle (Fig. 2). If adjust-
ment is necessary, turn the connecting rod, as required to obtain the de-
sired dimension.
THIS ADJUSTMENT IS FOR WRAP AROUND SERGERS ONLY.
Figure 3
5mm
ADJUSTING THE UPPER LOOPER
Will be done like machines with spreader. But the distance between the
needle and looper are to be adjusted like (Fig. 3).
THIS ADJUSTMENT IS FOR ALL 81200 CLASSES EXCEPT WRAP
AROUND SERGERS.
/2 mm
SETTING THE NEEDLE BAR
Set the needle bar so that the top of the needle eye is even with the underside of the looper, when the
looper point in its travel to the left projects 1 - 1.5 mm =0.04 - 0.06" from the left side of the needle. If ad-
justment is necessary, loosen the clamping screw in the needle bar connection and move the needle bar
up or down as required and retighten screw.

THREADING AND ADJUSTMENT
INSTRUCTIONS

LENGTHEN
STITCH
Figure 6
1. Adjust the stitch length to give the desired number of stitches per inch. This adjustment
is made by loosening the stitch regulator stud nut (#HA 18 A) on the side of the feed rocker
(#80233) (Fig. 6). Raising the feed driving arm (#80651) shortens the stitch and lowering it
lengthens the stitch. After the stitch length is set, reset the rear needle guard so that it barely
contacts the needle when in its most forward position of travel.
2. Regulate the pressure on the presser feet so that the springs exert a pressure sufficient
to feed properly. A comparatively heavy pressure is usually required.

3. Adjust the left hand looper thread take-up (#81266 K) outward or clockwise
until the left hand looper thread just tightens as the left hand looper thread comes off
the right hand looper. (CAUTION: NO LEFT HAND LOOPER THREAD SHOULD
BE DRAWN FROM THE CONE AT THIS TIME.) All the left hand looper thread
should be drawn from the cone as the left hand looper moves to the end of its travel
to the right.
4. The needle and the right hand looper thread tension should be set as low as
possible yet high enough to give positive and consistent control to the needle and
right hand looper thread. The left hand looper thread tension should be just high
enough to give a beaded appearance of the lower thread at the purl or edge.
5. Make sewing test on a single thickness of rug material. If satisfactory sam-
ples are not obtained, check the following thread controls.
6. NEEDLE THREAD CONTROL
To pull less needle thread into the stitch, or move purl down, increase needle
thread tension, or raise needle frame eyelet. Most of the needle thread should be
drawn from the cone on the upstroke of the needle.
7. RIGHT LOOPER THREAD CONTROL
To pull more right hand looper thread into the stitch, or move purl down, re-
duce the right hand looper thread tension or move right hand looper thread take-up
(eyelet) clockwise, being careful that the left hand looper gauge is not changed when
nut (#9937) is loosened.
8. LEFT HAND LOOPER THREAD CONTROL
The left hand looper thread control eyelet (take-up) should be adjusted out-
ward or clockwise until the left hand looper thread just tightens as the left hand
looper thread should be drawn from the cone as the left hand looper moves to the
end of its travel to the right.
