The Belt
The belt should not be too tight, nor should it be so
loose, that it slips. If the belt is too loose, r'emove
the hook at one end, shorten the belt and rejoin.
Maschine Working Heavily
Should the machine run hard after standing idle for
some time, apply a little oil for cleaning in the oiling
places, and then run the machine rapidly. Then wipe
clean and oil the machine anew with SINGER Oil.
To Avoid Breaking the Needles
It is important that the presser foot or the attach­
ments used in its place are securely fastened to the
presser bar. Do not sew heavy seams or very thick
goods with too fine a needle. For heavy work a large
needle
and correspondingly thick thread should be
used (see chart on page 64).
It is important to see that the needle is not bent, and
avoid pulling of the material while sewing, in order
to prevent the needle from striking the throat plate
and becoming damaged.
Breaking of the Needle Thread
This inconvenience can be caused by the following:
Improper threading, too tight upper tension, thread
too coarse for the size of the needle, needle bent,
blunt or improperly set into needle clamp.
Breaking of the Bobbin Thread
This may be caused by:
Improper threading of the bobbin, too tight lower
tension.
Skipping of Stitches
This can occur if the needle is not accurately set into
the needle bar, or the needle may be blunt or bent,
or it may be too small for the thread in use.
