ELECTRICAL INFORMATION
The Singer electric motor is located at the back of the machine, and can be
supplied for operation on alternating or direct current. Orders must state the
catalogue number of the motor, or the voltage, and in the case of alternating
current, the number of cycles.
Before inserting electrical plug, be sure that voltage and number of cycles
stamped on motor nameplate are within range marked on electric meter installed
by electric power company.
Electrical Connections for Machine: Push three-pin safety plug into three-pin
terminal block at right of machine and connect plug at other end of cord to
electric supply point.
Speed Controller: The speed of machine is regulated by amount of pressure on
foot or knee controller.
CAUTION! When you have finished your sewing always disconnect the
plug from the electric supply point.
LIGHT
To turn light "on," reach over machine arm and turn switch V, Fig. 1 to right. To
extinguish light, turn switch to left.

If the Machine is Electrically
Operated
Raise presser foot Qby means of
presser bar lifter Rto prevent injury to
the foot Qand feed T.
Place a piece of material under presser
foot and let the foot down upon it. Turn
on electric current and, if the
combination knee and foot controller is
installed as a knee controller, press
knee lever to the right. If controller is
placed on the floor to be used as a foot
controller, press down on pedal of
controller. The speed of the machine is
controlled entirely by the amount of
presser applied to the controller.
Operate machine in this way, without
being threaded, until you have become
accustomed to guiding the material and
operating the controller.

If the Machine is Hand Operated
When the machine is uncovered, the
hand attachment will be found to be out
of working position as shown in Fig. 6.
Pull the small spring stud 2, and turn
the handle back until leer 1, enters the
socket 3. Press back the hinged finger
4, Fig. 7 between the spokes of the
wheel. The machine is now ready for
working as shown in Fig. 7.
NOTE. Before replacing the cover on
the machine in its case, the lever
should be disengaged and the handle
placed in the position shown in Fig. 6.
To Operate the Hand Machine
Place a piece of material under the presser foot Q, Fig. 5, and lower the latter by
means of the lifter R. Now turn the handle over from you to work the machine,
without being threaded, until you are accustomed to guiding the material with the
left hand.

If the Machine is Treadle Operated
Loosen the hand wheel by turning motion screw L, Fig. 16, over toward you,
place both feet upon the treadle and turn the hand wheel over toward you, at the
same time allowing the feet to move freely and lightly with the motion of the
treadle. Continue to do this until a regular and easy movement is acquired and
you are able to work the treadle so that you can re-start the machine with the
wheel turning toward you.
When familiar with the working movement, tighten the hand wheel by turning the
stop motions screw over from you, and place a piece of material under the
presser foot Q, Fig. 5. Lower the latter by means of the lifter and again work the
machine without being threaded, until you are accustomed to guiding the
material.
The belt should be only just tight enough not to slip. If too loose shorten and
rejoin. Belt Shifter
This device simplifies throwing off and
replacing the belt. To throw off the belt,
move the belt shifter to the left (see Fig.
8), working the treadle at the same
time. To replace the belt, work the
treadle slowly with the hand wheel
turning toward you, when a revolutions
or tow of the wheel will bring the belt
back into its place.

Protection Against Rust Damage
Lint and fluff, if not removed prior to storage will, during humid periods, absorb
and hold moisture, and thus accelerate rust damage to highly polished thread
handling and other exposed parts. The extend of rust damage would depend
upon the length of time the machine remained in idle storage where there is no
ventilation. Sudden drops in temperature till cause moisture to form on parts
which, if not protected by a film of oil, would rust and damage while in storage.
Proper storage care suggests thorough brush-cleaning to remove all traces of lint
and fluff, followed by swabbing of all the exposed parts in Figs. 10 and 11 with a
lint-free brush saturated with SINGER oil. SINGER lint-free brush may be
purchased at your local SINGER dealer.

To Oil the Machine and Stand
If the machine is used continuously, it should be oiled daily. If moderately used, an
occasional oiling is sufficient. Apply one drop of oil at teach of the places indicated
by the unlettered arrows in Figs. 9, 10 and 12 and carefully clean the machine to
insure smooth and satisfactory performance. Oil holes are provided in the machine
for bearings which cannot be directly reached.
Remove face plate D, Fig. 9 by taking out screw Cand loosening screw Enear the
top of the place. Slip plate over screw E. Oil the points indicated in Fig 10 and
then replace face plate D.
Draw the slide to the left (as shown in Fig. 9) and, after removing the lint and dust
which may have accumulated (see instructions on page 24), apply a drop of oil at
the place indicated at F, Fig. 11. The slide should then be closed.

Class 99 & 99K
To oil the parts underneath the bed of the machine, turn the machine back on its
hinges and apply oil to the oil holes and bearings indicated in
Fig. 12.
To oil the stand, apply a drop of oil to the centers upon which the band wheel and
treadle work, and to both ends of the pitman rod connecting the treadle with the
band wheel.
After oiling, run the machine rapidly for a few minutes so that the oil may reach
the bearings. Neglect to oil the machine will shorten its life and cause you
trouble and annoyance.
Always use SINGER oil. Inferior oil clogs the bearings, prevents efficient
working, and causes rapid wear of the mechanism.
