INSTALLATION
Machine base and oil reservoir shown in Fig. 2,
fits into standard table cut-out and rests on the four
corners without bolting.
Rasp edges of cut-out, if necessary,as base must
be located so thot machine does not touch table.
Use shims on corners, If necessary, to prevent base
from rocking.
Base must be level in both directions so that oil
level will be accurately indicated by marks on base.
Machine bed rests on felt gasket In base. Fig. 2,
and is not bolted down.
Machine hinge pins must not support the head except
when it is tilted back.
CAUTION: Do not start machine until it has been thor
oughly lubricated as instructed below.
LUBRICATION
Machines of Class 262 have an automatic lubricat
ing system in which oil is circulated from a reservoir
by means of a centrifugal pump, and is delivered under
pressure to all principal bearings.
Before starting machine, the oil reservoir which
holds approximately 1 -3/4 pints must be filled to high
mark, as shown in Fig. 2.
Use SINGER* OIL "TYPE A" or "TYPE C". Use
"TYPE C" OIL when an oil is desired which will
produce minimum stain on fabrics.
NOTE: When machine is new or has been idle for some
time, remove face plate and oil the upper and lower
needle bar bushing wick by hand. The outomatic oiling
system will fuction efficiently after the first few min
utes.
Check oil level often to keep it from going below
mark.
CAUTION: If the flow of oil passing the oil flow window
shown in Fig. 3, should stop or become erratic, stop
the machine immediately and do not run machine until
the trouble has been eliminated.

toward operator. Re-adjust take-ups if necessary.
Securely tighten set screw right and two set screws
TO ADJUST AUXILIARY THREAD TAKE-UP
Auxiliary thread take-up,Fig. 40, should aid in set
ting stitch by taking up slack of needle threads as
needle bar finishes its downward stroke and should
start to set stitch as needle thread loops are shed
from loopers.
Loosen set screw and raise or lower auxiliary thread
take-up as required. Then securely tighten set screw.
Desired setting for auxiliary thread take-up
may
vary with changes of thread or materials in use.
TO ADJUST NEEDLE THREAD EYELET
Loosen the two screws shown in Fig. 40 and set
eyelet so that loopers back out of needle threod loops
with slight amount of tension on needle threads. Se
curely tighten two screws.
TO ADJUST NEEDLE THREAD TENSION RELEASERi
Tension releoser must release tension on needle
threads and looper threads when presser foot is raised.
Tension should not be even slightly released when
presser foot is down.
Loosen set screw. Fig. 41.
Turn shaft. Fig. 41, over to left until correct ad|ust-
ment is obtained.

SETTING FEED DOG AT CORRECT HEIGHT
Feed dog height adjustment should be mode with
machine set for longest stitch (See Page 8). At this
setting, the full depth of rear teeth of feed dog should
project above top surface of throat plate, as shown in
Fig. 42.
Height of feed dog is determined by height of stop
screw shown in
Fig. 43.
To adjust feed dog height, loosen feed dog screw
shown in Fig. 42 and loosen lock nut on stop screw.
Fig. 43. Raise or lower stop screw as required to
obtain correct height. Then securely tighten lock nut
and feed dog screw.
SETTING THE TILT OF FEED DOG
Front of feed dog may be tilted up or down to obtain
an even flow of both plies of material under the press-
er foot.
Loosen clamp screw shown in Fig. 43 and r'aise
or lower rock shaft crank to tilt feed dog up or down.
Then tighten clamp screw securely.
CENTRALIZING FEED DOG
Feed dog should never contact edges of throat
plate slots.
Sidewise Setting
To move feed dog toward left or right, loosen two
feed bar clamp screws, crank clamp screw D and four
collar set screws shown in Fig. 44.
Adjust feed dog carrier so that feed dog moves in a
line
midway between sides of throat plate slots. Then
align rock shaft crank with feed dog carrier. Securely
tighten all screws.
Lengthwise Setting
To move feed toward front or rear ends of throat
plate slots, set machine for longest stitch, as instruct
ed on Page 8. Loosen crank clamp screw E, Fig. 44
and move feed dog carrier as required to centralize
feed dog midway between front and rear ends of throat
plate slots. Securely tighten crank clamp screw E.
TIMING THE FEED DOG
Feed eccentric shown in Fig. 45 should be set
so that feed dog starts its feeding movement immedi
ately after needle leaves material and stops before
needle re-enters material on downward stroke.
From the library of: Superior Sewing Machine & Supply LLC

Setting
Remove large cop from top of mochine and loosen
three set screws on feed eccentric, as shown in Fig.
45.
Turn feed eccentric over toward operator to start
and stop feed motion sooner, or away from operator
to start and stop feed motion later.
Tighten three set screws and replace cap.
TIMING THE FEED ROLL (MACHINES 262-20 AND 262-32)
Feed roll on Machines 262-20 and 262-32 should
be timed so that roller begins its movement as soon
as feed dog starts its feeding movement.
Remove needle thread tension regulator bracket
from machine and remove arm cover.
Loosen three feed roll eccentric screws shown In
Fig. 46.
Rotate feed roll eccentric toward operator to start
movement of feed roll sooner, or away from operator
to start movement of feed roll later as shown In Fig. 46.
Tighten three feed eccentric screws and replace
arm cover and tension regulator bracket.
SETTING THE FEED LIFTING ECCENTRIC
Position of feed lifting eccentric, Fig. 47, deter
mines shape of elliptical path taken by feed dog. Thus
eccentric determines dlstarKre feed dog will rise and
fall, and point where feed dog will contact and drop
away
from material.
Remove cover from rear of machine arm.
Loosen three lifting eccentric screws shown in
Fig. 47.
Turn machine pulley over toward operator until feed
dog begins to move forward.
Rotate lifting eccentric. Fig. 47, until connecting
rod is at its lowest point and feed dog begins to rise.
At this point, center screws on feed eccentric, lift
ing eccentric, and bevel gear should be in line, as
shown in Fig. 47.
Securely tighten three lifting eccentric screws.
Eliminate excessive backlash in bevel gears shown
in Fig. 47, by loosening horizontal bevel gear set screw
and
moving gear toward or away from upright bevel
CAUTION: Bevel gears shown in Fig. 47 have been
lapped together at the factory and must be kept in mesh
atoll times.
