3.14 USING THE GAUGE
The gauge is a necessary tool for adjusting Models 100 and 101. The following should be used as a
reference for your machine. The gauge (part #
10230
) has three important dimensions for three
separate measurement functions.
1. The thickness of the gauge is 1/16” (1,6mm). It is used to check the height of the feed dog
above the throat plate at the top of the stroke (see
Illustrations 35
). The measurement is made
with the presser foot on the machine and no thread or tape between the foot and the feed dog.
The gauge should just fit between the plate and presser foot. If it does not fit, the feed dog
should be checked for wear and replaced if needed. If the feed dog is not worn then adjust to the
1/16” (1,6mm) height.
2. Standing the gauge on edge, check the height of the needle at the top of its travel. The needle
height should be 1-1/8” (28,6mm). Refer to
Illustration 34
. The throat plate must be on the
machine for this check because the measurement is made from the throat plate to the bottom of
the eye of the needle. This dimension is very critical. Follow the adjustments in section
3.9.8
NEEDLE HOLDER ADJUSTMENT (page 26)
, if this dimension is not correct. Be sure the
needle is in the chuck all the way. The cut away portion, ¼” x 1-3/8” (6mm x 35mm), allows
this check to be made when the feed dog is on the machine. The needle and feed dog will be at
the top of the stroke at this point.
3. The third use of the gauge is to check the stroke or timing of the looper relative to the needle.
Refer to
Illustration 36
. With the looper to the right of the needle as far as it will travel or with
the looper retracted into the machine as far as it will go, measure from the center of the needle to
the tip of the looper. The small “
V
” in the gauge is now placed on the needle. The looper can be
adjusted so the gauge clears the looper and that the looper is right up to the gauge. Follow the
adjustments in section
3.9.5 FINE TUNING THE DISTANCE BETWEEN THE NEEDLE
AND THE LOOPER (page 25)
, if this dimension is not correct.
