MH-481, 481-5(4), 484, 484-5(4), 486-5(4) (September, 2003) 1/2
MH-481-5
● The machine comes with a thread spreading mechanism
and an adjustable needle guard to prevent stitch skipping.
The thread clamp mechanism, tension release mechanism
and needle thread draw-out mechanism enable the
machine to leave thread of a uniform length after thread
trimming, and prevent slip-off of the needle thread.
All of these mechanisms contribute to upgraded sewing.
● Safety stitching (condensation stitching) the perfect
method of preventing loose stitches, or reverse feed
stitching (back-tacking) can be alternated through the
simple adjustment of the stopper of the reverse feed lever.
Either sewing method can be used.

(with automatic thread trimmer)
1-needle, Double Chainstitch Machine
● The differential-feed is the best-suited feeding device
when sewing elastic materials including double-jersey or
light-weight materials such as satin or georgette.
Beautiful, elastic seams are created, while puckering,
thread breakage and thread fraying are all prevented.
● The sewing method can be alternated between stretch
stitching and shirr stitching with the simple operation of
a lever. This lever is also used to adjust the differential-
feed ratio.

MH-484-5(4)
(with automatic thread trimmer)
1-needle, Double Chainstitch Differential-feed Machine
● The machine comes with many different functions to prevent
uneven material feed and puckering for higher-quality seams.
The machine is adaptable to a wider variety of light-to heavy-
weight materials and takes full advantage of top-feed
mechanism. This enables unskilled operators to finish seams
of consistent quality.
● The machine comes with a forced lifting mechanism for the
top-feed dog. This enables the operator to place the material
to be sewn on the top-feed dog more smoothly. The machine
incorporates its exclusive chain-off thread presser pedal foot,
which improves seam quality and ease of operation.
