INSTRUCTIONS for USING this BOOK
GENERAL INDEX to ALL subjects appears on Pages 3 to 6.
GENERAL INSTRUCTIONS applying to ALL MODELS appear on Pages 7 to 16. These in-
structions cover adjustments, threading, needle sizes, etc. covering all models.
ADDITIONAL INSTRUCTIONS for EACH MODEL appear on Pages 17 to 31. These instruc-
tions cover the special features of each model which do not apply to other models. See

HOW TO ORDER PARTS
For your convenience in finding parts and part numbers, we have broken down the machine into
its various component groups (such as main shaft group, presser foot group, needle drive
group). Pictures of these groups are shown in PLATES numbered from A to 33. The Plates
I
are listed in the Index (Pages 4 and 5) with a description of the Group and the model numbers I
of the machines in which these groups are used.
All the groups used in each model are also listed under the Model heading (See Index Page 3
for each model).
The CROSS-REFERENCE CHART on Pages 33, 34, and 35 show the Groups and the various
models in which each group is used.
To find any part number, first refer to the Model number and Serial number stamped into the
top cover of each machine. Determine the group in which each part belongs, find the Plate for
this group, and locate the part and its number. The descriptions of the parts are on the page
opposite each Plate.
If the part number is known, refer to the Numerical Index (Pages 105-108) to locate all of the
Plates of Groups where the part is used.
ORDER by PART NUMBER, giving DESCRIPTION, QUANTITY, MODEL number and
SERIAL number of the machine.

INSTRUCTIONS FOR THE INSTALLATION,
ADJUSTING AND OPERATION OF ALL
COLUMBIA CLASS 300 MACHINES.
UNPACKING AND SETTING UP OF MACHINE
7
1. To remove the machine from the box, take off the cover. Use a nail puller to avoid
breaking the machine. Be sure to look carefully through the material used for packing before
destroying it, so that all the parts and equipment that go with the machine will be found. Lift
the machine out of the box very carefully to avoid breaking the tension studs, as these parts
project beyond the head of the machine. Small parts will be found wrapped in a package.
l, Set up the machine; clean away accumulated lint and dust, especially from the
looper.
3, Place the machine on the bench with the pulley lined up with the transmitter. The
machine should be set on the table so that the knee lever is 1/2" from the edge of the table.
4. Mark the two holes for the machine screws and bore for the screw holes; bore the
hole for the belt; place the felt pad under the machine and fasten the machine to the table, using
the two machine bolts in the package of parts shipped with the machine.
5. The machine may be run 3000 revolutions per minute; it is suggested, however, that
the machine first be operated at about 2500 revolutions per minute until the operator becomes
used to the machine, and then step up the machine to increase the speed.
6. We reserve the right to change specifications or designs at any time, without in-
curring the obligation to install such changes on machines previously manufactured.
HAND WHEEL
7. The hand wheel turns away from the operator in clockwise direction.
OPERATING THE MACHINE
OILING
8. Before starting the machine make certain that all oil cups, and all openings m~rked
with red paint, are filled with oil. Should your machine have a Top Plate stamped "OIL" push
the plate to one side, oil all the openings, reset and lock the plate.
SPEED
9. Check the speed of the machine. The machine should run at a minimum speed of
2500 revolutions per minute, and should not exceed 3000 revolutions per minute.
10. To be certain that there are no obstructions in and around the machine, press the
knee-lifter to the right, turn pulley by hand in the direction of the arrow a complete turn.

GENERAL INSTRUCTIONS
THREADING
11, To thread the machine turn the belt pulley by hand until the needle arm is in its
h i ghest possible position, Proceed as shown in Threading Chart Page llB. We suggest /#00
mercerized thread.
INSERTING WORK
12. To insert work in the machine, press the knee lifter to the right. (This lowers the
Apron,) Then place the folded edge or sewed edge of the garment DIRECTLY UNDER the
small curved slot in the gauge on top of the presser foot. Once this is done, the rest of the
fold should be held against the guide extending in front of the presser foot. In operating the
machine, just watch this guide (not the needle).
ADJUSTING NEEDLE PENETRATION
13. Run off a few test inches and inspect the work. If the needle does not catch the
fabric as desired, adjust the penetration by turning the dial indicator marked "MORE" or
"LESS", following the instructions below:
14. Turn this dial indicator either to the right for less penetration, or to the left for
more penetration, until the needle catches the bottom layer of the garment properly.
15. Usually it is sufficient to move the dial indicator a few graduations (NOT turns)
to the left, to obtain the desired stitch, however, should you move the dial indicator a few
graduations and get no results, then look for trouble at the point of the needle, which, very
likely, will have been turned up to a feather-edge, causing a dull point that prevents the needle
from penetrating the fabric properly. Pass your finger over the edge to see if the needle has
this feather-edge. If it does, discard the needle.
NEEDLE REPLACEMENT
16. Before inserting the new needle, turn the dial to the right, ("LESS") until the rib,
or plunger, remains clear of the needle, or else the needle will get a defective point again as
soon as the machine is started.
17. When replacing the needle, make sure that it is pushed up as far as it will go, and
tighten tp.e screw. Then turn the belt pulley slowly and look to see that the full bend of the
needle in back of the eye, rides on the needle guide before the needle enters the work. If it
does not , take the needle out and curve it just eno-ugh to make it rest on the guide, under a
slight tension.
STARTING TO SEW
18. You are now ready to proceed with the production. Press the knee-lifter to the
right; insert the work as explained above, release the knee-lifter, and guide the work as the
machine pulls it from you.
From the library of: Superior Sewing Machine & Supply LLC

...
GENERAL INSTRUCTIONS
DO NOT touch the knee-lifter while the machine is in operation.
LOOP SKIPS
19. In case the thread breaks too frequently, or the loop skips, or the fabric gathers,
correct this fault by adjusting the tension disc by turning the nut either right or left until you
get a smooth line.
REMOVING WORK
9
20. To remove the work after stitching, see that the needle is withdrawn entirely from
th e fabric, push the knee-lifter to the right, and remove work with a quick pull away from you,
in order to break the thread and lock the stitch.
NEEDLE SIZES
21. Needles are furnished in the following sizes, order by size number.
NO. NO.
Ordinarily, sizes 2-i and 3-k needles will serve the purpose. A full range of needle
sizes are, however, available to meet all requirements.
22. Use ONLY genuine COLUMBIA needles. Look for the copyrighted word
Columbia printed on each box of needles,
THREAD
23. Use any good grade of left-twist three cord hard finish cotton thread in sizes 70 to
100. We recommend No. 00 Mercerized thread or its equivalent. If silk thread is used, select
either •• 00" or "000".
REGULATOR FOR DEPTH OF NEEDLE PENETRATION
24. The needle penetration adjustment is located on the front of the arm column of the
machine, and is a dial that has graduations, show the word "MORE" which indicates the direc-
tion in which to turn the dial lever for a deeper needle penetration; and the word "LESS"
which indicates the direction to turn the dial lever to obtain less needle penetration in the work.
(See work apron adjustments for setting regulator).
TIMING
25. All basic driving parts are properly timed with spot screws.
