GENERAL INSTRUCTIONS FOR THE INSTALLATION,
ADJUSTMENT, AND OPERATION OF LEWIS CLASS
150 MACHINES
UNPACKING MACHINE
7
To remove the machine from the box, take off the cover
and remove the nails and screws that hold the brace blocks in
position. Use a nail puller to avoid breaking the machine. These
blocks are held by nails or screws driven through the outside of
the box. The knee lifter is attached to the side of the box, and
the other small parts will be found wrapped in a package. Be
sure to look carefully through the material used for packing be-
fore destroying it, so that you will find all the parts and equip-
ment that goes with the machine. 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.
Set up the machine; clean away accumulated lint and
dust, especially from the looper.
Place the machine on the bench with the pulley lined up
with the transmitter, and, assemble the knee lift lever to the
machine, The machine should be set on the table so that the
knee lift lever is 1/2" from the edge of the table.
Mark the three holes for the machine screws and bore
for the screw holes; bore the hole for the belt; place the f.elt
pad under the machine and fasten the machine to the table, using
the three machine bolts that were used to hold the machine into
the packing case.
HAND WHEEL
The top rim of hand wheel turns, when facing the pulley,
away from the operator or clockwise. The pulley is 2" diameter
at the pitch line of the belt groove.
THREADING
From the spool stand, pass the thread through the eye-
let just back of the tension disc, then between the tension disc
on the left side, then lift thread over the pin which passes
through the tension discs; then through the pig-tail eyelet over
the needle bar, then through the hole in the needle clamp, then
through the eye of the needle.

REMOVING WORK
See that the needle is out of the cloth. Lower the feed
plates and retract the disc and give the work a quick jerk which
will break the thread.
We reserve the right to change specifications or de-
signs at any time without incurring the obligation to install such
changes on machines previously manufactured.
NEEDLE SIZES
The needles are furnished in the following sizes, order
by number:
Taper Point

purpose. A full range of needle sizes are, however, available
to meet all requirements.
Use ONLY genuine LEWIS needles. Look for the copy-
righted word "LEWIS" stamped on the shank of each needle.
THREAD
Use any good grade of left-twist three cord hard finish
cotton thread in sizes 70 to 100. If silk thread is used, select
either "00" or "000".
REGULATING DEPTH OF NEEDLE PENETRATION
The needle penetrating adjustment is located on top of
the cylinder base of the machine and is a dial with graduations,
showing the word "More" and indicates the direction in which to
turn for raising the ridge forming disc for a deeper penetration;
and the word "Less
II
which indicates the direction to turn the
dial to obtain less needle penetration in the work.

SKIPPING STITCHES
Examine point of needle to see if it is blunt or turned
over. Replacing needle will generally remedy skipping of
stitches.
REPLACING NEEDLE
Insert needle into needle carrier as far as possible
and tighten set screw. Needle should bear slightly on the
needle guide.
IMPORT ANT -- OIL MACHINE DAILY
SPEED
The LEWIS Class 150 machines can be operated up to
3000 stitches per minute. A speed of 1800 to 2000 stitches is
recommended in starting a new machine or with a new operator.
Speed may be increased to suit operator or class of work.
TIMING
All basic driving parts are properly timed with spot
screws.
PRESSER FOOT
Place new needle in the needle carrier as far as possi-
ble and with the point directly over the needle guide adjust the
foot up or down so that the point of the needle is under scant
.010" tension. Observe that shank of needle passes over the
needle guide freely.
RIDGE FORMING DISC (Refer to Plate lA)
The disc must be adjusted to be in the center of the
slot in the presser foot, and so that the nose of the disc is set
in relation to the needle, Models 150-1, 150-6, 150-6TS, 150-7,
150-17. For other models, refer to special instructions on model
in question.
Before setting the disc be sure that there is no end
play to the cradle 140-11. Any end play can be taken up by ad-
justing the pivot bearing screw 18-869, Set Screw 1003 must
first be loosened and the tension of Spring 21-377 released.
