DESCRIPTION
Machine 300w103 has one needle and one looper and makes a
single row of two-thread chain stitching.
Machine 300w203 has two needles and two loopers for simultane
ously making two parallel rows of two-thread chain stitching. The needles
are set abreast and the distance between them may be from 3/16 Inch
to 1 inch, in stepsof 1/32 inch, as ordered. The standard gauges are 1/4",
5/16", 3/8", 1/2" and 3/4".
These machines are especially adapted for seaming overalls and
work pants, automobile trim, stitching tarpaulins, tents, seat covers and
similar work in medium and heavy fabrics.
A compound feed, consisting of needle feed and drop feed, working
in combination with alternating pressers, comprising on upper feeding
foot and lifting presser foot, carry the work forward in unison with the
needle in the material, insuring powerful, positive and even feeding of
two or more plies of material.
The maximum length of stitch is 3 to the inch. The needle bar stroke
is 1-1/4 inches and the presser bar lift is 3/8 inch.
An automatic oiling system delivers the required amount of oil to all
principal bearings.
SPEED
The maximum speed recommended for these machines is 4000 R.P.M.,
depending upon the nature of the work. For the first few days, the speed
of the
machines should not exceed 3500 R.P.M., after which they can be
driven at their maximum speed. The top of the balance wheel turns over
toward the operator.
CAUTION: Before starting the machine, it must be thor
oughly oiled, as instructed on pages 6 and 7.

TO OfL THE MACHINE
The machine has an efficient automatic citing system comprising a
hollow arm shaft and o hollow bed shaft which act as oil reservoirs and
deliver the required amount of oil to all of the principal bearings when
the machine is in operation. The oil is distributed to the various bearings
by centrifugal force through small jets in the shafts so that only clean
oil reaches the bearing surfaces. Oil holes ore provided for hand oiling
of parts in movable contact which are not oiled from the reservoirs.
CAUTION: Use "TYPE D" OIL sold by Singer Sewing
Machine Company. See inside front cover for description of
this oil-
THE MACHINE MUST BE OILED AS INSTRUCTED BELOW AND ON
THE FOLLOWING PAGE. FAILURE TO DO THIS WILL RESULT IN DAM
AGE TO THE MACHINE.
NOTE: It is not necessary to remove the work plate for the
first servicing or subsequent oiling of the machine. For this
purpose, merely swing out the face plate and remove bed slide
plate.
USE ONLY THE PRESSURE OIL CAN NO. 228491 FURNISHED WITH
THE MACHINE, AS SHOWN IN FIGS. 6 AND 8.
TO OIL ARM
SHAFT
1. To fill arm shaft
oil reservoir, insert
spout of pressure oil
can in hole D, Fig.
6 and inject 6 shots
of oil into shaft.

2. To fill bed shaft oil reservoir, push spring cover E, Fig. 7 to left,
insert spout of pressure oil can in hole F, Fig. 8 and inject six shots
of oil into shaft. Close oil spring cover E.
NOTE: The arm shaft and bed shaft con also be oiled from
right hand ends.
3. Apply oil to work plate oil holes and arm oil holes. Oil needle bar
bearings and connections, needle bar rock frame bearings, looper
rocker sleeve, presser lifting mechanism and looper pull-out rack.
AMACHINE IN DAILY USE MUST BE OILED AS FOLLOWS:
Fill arm shaft oil reservoir D, Fig. 6 (approximately 6
shots of oil).
Fill bed shaft oil reservoir F, Fig. 8 (opproximately 6
shots of oil).
Once a day Apply oil to all holes in work plate.
Oil needle bar bearings and connections and needle bar
rock frame bearings.
Oil looper rocker sleeve.
Oil feed
lifting rock shaft bearings in back of arm.
Occasionally oil tension release mechanism and looper pull-out rack.

Pull table slide toward you and turn balance wheel over toward you
until needle bar isat its highest position.
Move loopers out of sewing position, by pulling rod H, Fig. 11 out
1/4" and gear rack button G, Fig. 11 as far as It will go. This will make
threading easier and prevent accidental operation of machine before
loopers are returned to sewing position.

and pass both looper threads over one arm of take-up wire
shown in Fig. 13. Adjust tension to suit.
