Automatic lubricating mechanism helps improve maintainability. The machine is provided with a sub oil pan and double filter to keep dust from entering the oil.

The machine is equipped with a bottom- feed adjusting mechanism that adjusts the amount of bottom-feed while keeping the needle feed fixed. With this adjusting mechanism, the machine can prevent uneven material feed without changing stitch pitches.

Since the needle thread tension-release solenoid is fitted on the rear face of the machine head, the area around the needle entry and one-touch type reverse feed button is easily viewable. This substantially contributes to improved operability.

The vertical strokes of the presser foot and walking foot (their alternating vertical movement) can be easily changed using a large dial mounted on the top surface of the machine head.

In addition the sewing speed is automatically adjusted with the set value. With this feature, ideal sewing conditions are maintained at all times.

The machine is equipped with an instantaneous changeover device for alternating the vertical movement amount of the walking foot and presser foot, which demonstrates its capability for processes involving sewing products with a lot of multi-layered portions.

The machine leaves a shorter needle thread after thread trimming, improving thread consumption efficiency. With a rigid knife and improved cam shape, the thread trimmer cuts thread as thick as #5 without fail.

With just a light press on the one-touch type reverse feed button, reverse feed stitching is actuated. Furthermore if a suspended ruler is attached on the machine or a 3-dimensional sewing product is sewn, the button can be shifted upward to prevent interruption.

The auto-lifter (pedal switch type) helps to increase efficiency by reducing operator fatigue.

The 1-needle type machine is equipped with a bottom-feed micro-adjustment mechanism with the needle feed amount fixed. This helps prevent irregular stitches which are free from pitch errors.

The new mechanism with a rectangular feeding motion promises consistent feed of materials of all thickness without stitch gathering.

The lower orbit of the feed dog prevents the material from flopping and reduces operating noise and vibration.

The machine has adopted a new mechanism that does not change the ratio of alternate vertical movement of the walking foot and presser foot even when the material thickness changes.

Even when a heavy-weight material is used, the presser foot lift does not decrease. This means that the presser foot comes into contact with the material at exactly the same time that it does when sewing lighter-weight sections of the material. As a result, the walking foot retains the material with a consistent pressure to prevent irregular stitches.

The amount of the alternating vertical movement of the walking foot and presser foot can be adjusted up to the maximum of 6.5mm according to the height of multilayered portions of material.

With the adoption of a new rectangular feed mechanism, an alternating vertical movement mechanism, and a unison feed mechanism, the machine can feed heavy materials powerfully and smoothly. Well tensed seams are consistently produced without pitch errors.

With its maximum stitch length of 9mm, the machine can be applied to a broader range of uses.

The high, 16mm foot lift enables easy material handling.

The 1-needle type machine has adopted a dual-tension mechanism, with which the machine can support high-tension sewing with thick thread. This means that the machine produces seams of excellent quality on a broader range of materials, extending from light- to heavy-weight.

With the adoption of this vertical-axis double-capacity hook, the frequency of bobbin thread changing is reduced, promising sewing work of increased efficiency.

The stitch length can be easily selected by the stitch dial.

The machine is provided with many improved features that offer enhanced operability such as an easy-to-observe area around the needle, placement of the bobbin winder on the front face of the machine arm, and a large handwheel (φ160).

A knee-lifter mechanism is built in the bed. This reduces the pressure required to operate the knee-lifter and facilitates setup. (Machines equipped with automatic thread trimmer are excluded.)

The machine is full-open-type top design makes it possible to fully open the top of the machine arm. Thanks to this design, adjusting works can be done without tilting the machine head.

The machine is equipped as standard with a safety clutch for preventing hook breakage. Reset work can be done simply by pressing a button.
