SINGER 201K - Manual (Page 11)

Loosen the hand wheel by turning stop
motion screw 17, Fig. 12, oyer 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 move­
ment, tighten the hand wheel by turning
the stop motion screw over from you, and
place a piece of material under the presser
foot G, 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.
IF MACHINE IS TREADLE OPERATED
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 band wheel
turning toward you, when a revolution
or two of the wheel will bring the belt back
into its place.
