Where to Oil the Tucker
The only place on the Tucker that requires oiling
is the stud on which the marking lever works. See
Fig. j)7. One drop of oil occasionally is sufficient.
Careless oiling will result in oily blades and soiled
material. When the marking lever does not move up
and down freely it requires oiling. If neglected, it
may become so dry that it will stay down and cause
a drag on the material instead of lifting freely as
the mark is made.
To Attach the Tucker to the Machine
Raise the needle bar to its highest point, remove
the presser foot from the machine and attach the
Tucker in its place. Care should be taken to see that
the Tucker is securely fastened to the presser bar
and that the needle goes through the centre of the
needle hole. Note the position of the marking lever,
making sure that it is in the lower position and that
the needle clamp works on it as the machine sews.
How to Adjust the Scales on the Tucker
The width of the tucks and the space between
them is determined by the adjustment of the scales.
Adjustment for width of tuck is made by loosening
the tuck guide adjusting screw, which allows you
to move the tuck guide to the desired figure on the
luck scale. The tuck guide should be set just over
the figure you wish to use. The adjusting screw
should always be well tightened.

To adjust for the width of space between the tuct
loosen the space scale adjusting screw and move the
space scale until the desired figure is directly in a line
with the centre of the needle hole. You will find
a line in front and back of the needle hole to indicate
the centre.
Before starting to sew, tighten the screw well to
prevent the scale shifting when the Tucker is in
operation.
The figures on the tuck scale indicate the width of
tuck in eighths of an inch, the marks between figures
are sixteenths. The marks on the space scale arc
double the width of those on the tuck scale, so that
when both scales are set at the same figure, blind
tucks without spaces between them are made.
To make space between tucks, first set the tuck
scale, then move the space scale to the same number
and as much farther to the left as you wish to have
space. Each number on the space scale represents
one-quarter of an inch and each mark between
numbers one-eighth of an inch.
Use the table below to assist you in setting the
Tucker.
