structed in Fig. 4 above.
Back off screw 15 (turning screw anti-clock
wise) 1/2 turn. Check lubrication again.
To increase oil flow, turn screw 15 anti-clock
wise a small amount and recheck lubrication.
WHEN A MACHINE HAS BEEN IDLE FOR A CON
SIDERABLE TIME (OR AFTER A MAJOR INSTALLA
TION OF PARTS): Clean machine thoroughly. Then
apply a few drops of oil to oil grooves of feed bar
connections Q5 (see inset at bottom left of Fig. 4)
and to looper carrier connection guide bar at
02, Fig. 5 behind upper knife carrier and chip
guard. Apply a drop of oil to presser bar at

AFTER MACHINE IS INSTALLED AND BEFORE
STARTING MACHINE:
Remove belt and check freeness of machine by
turning machine pulley by hand. Replace belt.
Remove the chip guard from the front of the
machine.
Finally, “run-in” the machine for approximately
15 minutes at a moderate speed.

SPEED
Maximum speed recommended for these ma
chines is 5500 stitches to the minute. 5000 stitches
to the minute is recommended for long runs or
while sewing long stitches.
Maximum efficient speed is dependent upon the
nature of the operation, the ability of the operator
and the type of material being sewn.
It is advisable to operate these machines at
more moderate speeds the first few days, after
which they can be run at tap speed.
When the machine is in operation, top of ma
chine pulley must always turn over away from
operator.

below. Unless needle has the correct curvature,
it may cause skipping of stitches.
Orders for needles must specify the quantity
required, the Size number and the Catalogue
number
Selection of needles can make a great differ
ence in the ease and quality of the work, It is im
portant that each needle be lust right for machine,
thread and work being done.
For example
Choose your needle carefully. The correct size

The best stitching results will be obtained when
using needles sold by Singer Sewing Machine
Company.
CURVATURE OF NEEDLE BLADE
(Gauge 164588 for Needles of Sizes 9 to 16 only)
Before making any stitching adjustments, the
curvature of each needle blade should be checked
in the following manner:
Using gauge 164588, shown in Fig. 6, insert
shank of needle, with its flat side up, in the groove
A. Push the needle along the groove as for as it
will go against stop B. Tighten clamping screw C.
Swing the indicator D, slowly to and fro, along
the curve of the needle blade, observing the dis
tance between the needle blade and the tip of
the indicator.
\
C
The tip of the indicator should lust make con
tact at the needle eye and should clear needle
blade, at upper end of curve, by approximately
.005 to .006 inch. Use feeler gouge.

the setting of the stitch by taking up the slack of
needle threads as the needles finish their down
ward stroke; thus setting the stitch as the needle
thread loops are shed from the loopers.
When needles are at their highest position,
needle threads should run under clearance U3 of
needle thread controller J3, shown in Figs. 28 or
in fork U3 of controller J3, shown in Fig. 29.

TO SHARPEN THE TRIMMER KNIVES ON MACHINES
246K50
(See Figs. 38 and 39)
Knives on Machine 246K51 should be returned
to your SINGER Service Representative or to a
SINGER factory, when they require sharpening.
Knife Grinding Machine 701-9 (belt driven), is
necessary for sharpening the knives used on Ma
chine 246K50. The use of this grinder insures the
correct bevel of the cutting edge of each knife.
If this Knife Grinder is not available, knives that
require a new edge should be returned to your
SINGER Service Representative or to a SINGER
factory for sharpening.
Do not attempt to sharpen these knives by
hand.
Fig. 38. Sharpening the Movable
Knife
SHARPENING MOVABLE KNIFE D4:
Insert knife D4, Fig. 38 in knife holder B5, Fig.
38 on front of lever arm A5, Fig. 38. Allow ap
proximately 1/16 inch of the knife to extend be
yond holder, for grinding. Then tighten thumb
screw Z4, Fig. 38.
Turn thumb nut E5, Fig. 38 over from you until
the knife D4 clears the grinding face G5, Fig. 38.
While moving lever arm A5 alternately back and
forth, turn thumb nut E5 as required, to bring the
cutting edge of the knife lightly against the grind
ing face of the wheel.
Fig. 39. Sharpening the Stationary
Knife
SHARPENING STATIONARY KNIFE L4:
Insert knife L4, Fig. 39 in knife holder K5, on
rear of lever arm, so that its bevel M5 is parallel
with grinding face G5 of grinding wheel. Allow
approximately 1/16 inch of the knife to extend
beyond holder, for grinding. Then by turning
knurled end P5, Fig. 39 of lever arm, screw lever
arm into knife holder K5, securing the knife.
Sharpen the stationary knife as instructed above.
Continue the back and forth motion of the lever
arm, grinding off only enough to sharpen the
cutting edge.
The movable knife is thus ground to a shear
ing edge, requiring no special setting in the ma
chine to shear.
